Automotive Security: From Inflatables to Satellites

The year is 1910 and auto robberies are on the rise. A certain Mr. Bosco of Ohio has just wasted $5 on an ignition locking device that failed to prevent a determined thief to take the Bosco jalopy on a joy-ride.

Now, Mr. Bosco didn't quite take it kindly that the thief could take off with his ride in spite of having spent on an anti-theft deterrent device. In his rage, he had this brainwave that there is no better deterrent for a car thief than seeing a human in the car.

So Mr. Bosco launched the 'Bosco Collapsible Driver'. An inflatable imitation of Charlie Chaplin, the 'Collapsible Driver' was meant to be put away once the owner had returned to the vehicle. Now, the adverts of that time really tried hard to convince the general public that the 'Bosco Collapsible Driver' was the best thing to happen to a driver trying to save his car from robbers.

The 'Bosco Inflatable Driver Co.' sadly had to fold up within two years of opening shop, perhaps due to the fact that one could only have as many inflatables in cars. But it is rumoured to have laid the building blocks of the automotive security industry.

These days, we have security solutions that enable tracking of your precious vehicle using the entire communication network. Tracking the whereabouts via satellite in real time, you even receive updates on your cell phone at pre-determined intervals, to keep you relaxed about the location of your prized possession at all times.

As the digitization of our lives continues to grow in leaps and bounds, who knows what awaits us in our quest to keep our wheels safe...

City Roads - A roller-coaster ride

                                      (Source: Google Images)

You just gotta love the powers that head the Public Works Department in this crazy city fondly known as Bombay. Many a times I have wondered if they have their own magic carpets to waft around the city or do they have some sort of 'floo-network', a la Mr Potter.

                                   (Source: Google Images)

For I have never for one understood their twisted sense of humour, if it may be called so. The tarmac in this wonderful city has been under constant attack from myriad clueless agencies who come to work with a showel and an axe to pick. The planning boffins may have even been buried under a few feet of cobwebs by now, so long have they been absent from the city scape.

It truly is difficult to digest that the richest Municipal corporation in the entire country cannot provide its tax paying citizens some decent tarmac. The latest such example being the lovely idea of paving entire roads and junctions with interlocking cement blocks.

                                 (Source: Google Images)

Just ask the common man and you will realize why this was not such a great idea. But NO! The wonderful powers that be in the BMC decided to go ahead and do just that. Entire budgets were poured into lining the city streets with these paver blocks. Tarmac that could have been restored and maintained at a fraction of the cost was uprooted and these ugly things put in place.

The result? A bumpy and harsh ride that kills the backs of the citizens of this city. A health hazard and a nightmare for the poor drivers who navigate through the bumps and the sharp edges. And a city that curses its way 24/7 while it nurses its wounds.

                                   (Source: Google Images)

A cabbie recently told me - "Saab - Yeh BMC waale hai naa, hum log ko Essel World ki seher roz karaana chaahate hai, isliye yeh raaste aisi haalat mein chodte hai" Translation - The BMC wants us citizens to have a roller coaster ride similar to the ones available at Essel World, that's why they give us such roads!

Wake-Up Call!

                                    (Source: Google Images)


Its eight in the morning and the middle of the week. At a busy intersection somewhere in the suburban heart of the city that never sleeps, people are in their own world. Hurrying about to meet their daily commitments, they are unmindful of the fact that their life is tied to making it onto the 8.13 train! Meanwhile, back on the streets, its rush hour. In the networked world of today when everyone is said to be wired into the other; one incident made me question the entire situation.

A lady struggling to cross the street. Auto-rick guys, two-wheeler riders and car-drivers all swerve without bothering to allow the lady to cross. How much time does it take to pause a bit.... not much, but then again, the people are in some mad dash to get somewhere important. Eventually, she does manage to make it to the central median.

Something about her doesn't seem right. Everyone fails to notice her struggle. And then it happens. She trips and falls right in the path of the oncoming traffic. People watch, vehicles swerve around her. A few even have the gall to hurl abuses at her. Its as if everyone is engrossed in some cheap reality show. A young lady shows up, helps her to her feet and escorts her to the safety of the street curb.

People now snap out of their stupor and continue with their lives as if nothing ever happend. A newspaper guy begins to chide her for even attempting to cross the street. Yet another misguided soul comes up and mutters about why is it that some people just don't stay at home when unwell. The lady in discomfort finally pays heed to her samaritan and her assistant; and agrees to return home to rest!

Then comes another ordeal. The assistant is pleading with various rick-guys to help take an injured lady home. The heartless buffoons just swerve away with their meters half flagged. Finally one kind guy stops, hears the tale and whisks her away to safety.

That's it. A FIVE minute slice of life in the great city of blinding lights. Touted as the city that never sleeps, it was saddening to know that most people were caught napping in their apathy!

The V-12 (Vee Twelve) - An endangered breed...

                                    Source: taylorpatterson
As far as automotive nirvana goes, having a V-Badged car is an assured way to knowing that you have something special under the hood. A peculiar thing about this family is their equal numbered cylinders in the quest for balance and power. Starting with the V6, they reach their zenith with the most superlative of them all, the Beast! Reverently called so because of the huge lump of power that they exude, they are also called upon to power some of the most insane set of wheels in the world. In today's times of political and environmental correctness, this particular species of power-plants is a fast disappearing rarity. So rare is their appearance these days that they have gained their place in the endangered species of power-plants list.

                                     Source: motorwerksgroup

Mercedes-Benz have always been staunch believers in the power of the V-engine (Vee) design. It was back in the early nineties when they unleashed their flagship 6.0-liter V12 beast on the motoring world. Internally referred to as the M 120 Engine, it was a path-breaking design for Mercedes-Benz. Not only was it their first series-produced twelve-cylinder Mercedes-Benz passenger car, but also the most powerful Mercedes-Benz car engine of its day. The power and torque figures were rated at 300 kW (408 hp) and 580 NM respectively, with a staggering 500 NM of it available at just 1600 clicks! For some V12 aural nirvana, watch the short clip below.

The beast was kitted up with four-valve tech, a variable intake cam and a sophisticated electronic injection system with a hot-wire air mass sensor. All this high tech wizardry were in cahoots with each-other to try and keep both, exhaust emissions as well as fuel consumption down to a minimum. To put things into perspective for you, each cylinder had over 300 customized ignition maps with knock limiting in each case and were managed together by the ignition system! In-fact, the M-120 was the only twelve cylinder engine in the world to feature this sophisticated cylinder-selective anti-knock control.

The high compression ratio that was a result of all this tech-wizardry meant that engine and drive management would need to be looked at afresh. So, the control modules communicated via a common data channel, thereby rendering them jointly active. This feature made it possible for the rapid warming of the catalytic converters despite cold starts; it enabled the vehicle to find its grip on slippery surfaces via Acceleration Skid Control and a new engine friction torque control feature that allowed it to power out of slippery situations.

And the V12 saga continued with it offering the world’s largest catalytic converter unit for passenger cars. With a seven-litre volume, in order to avoid any excess fuel consumption on account of the catalytic converter, it ensured a high degree of long-term stability. An innovative design was used to create double and triple walled manifolds and pipes in the exhaust system. Together with these, the ceramic catalytic converters were embedded in insulating expandable matting.  This allowed them to reach their optimum operating temperature in a very short time, thereby aiding emissions control as well as controlling fuel consumption.

This beast of an engine has gone on to power some of the most special cars in the Mercedes-Benz family. Of these it is the W140 SEL 600, the most special of them all. A favourite of the most powerful people in the world, today these behemoths are being cared for by dedicated aficionados all over the globe.

The SLS AMG Formula-1 Safety Car

In recent years, AMG-Mercedes have been the chosen ones to lead the Formula1 pack as the official safety car. In the recently concluded 2010 Formula1 season, AMG-Mercedes pulled out a very special weapon in their arsenal - The SLS AMG super sports car.


                           Image Source: Mercedes-Benz

During the safety car period, the race cars have to be slowed down to a speed where their components are under severe stress. This is because, a Formula1 Race Car is a finely tuned hyper-sports machine built to extremely tight tolerances. While performing at the best under the optimal temperature range; outside it, they are left vulnerable to over-heating, tire-cooling, brake inefficiencies, etc. On the other hand, the safety car is literally moving along at max speed. Such are the opposite perspectives of the Race track and on the Road. Thus, any car aspiring for the safety car slot in Formula1 has to be supremely exceptional in all aspects.



                               Image Source: Mercedes-Benz

The engineering brilliance of the production SLS AMG has warmed the hearts of every Mercedes connoisseur and Formula 1 fans the world over.Featuring the same power-train package as the production car, the SLS AMG acting as the Safety Car 2010 ended up covering a distance of 88 laps, equivalent to a distance longer than a Formula 1 Race! The exceptional technology package for the super sports car ensured perfect driving dynamics and meant that no further technical modifications or lightweight-design measures were necessary. The sole exception was the all-new rear silencer, which allowed the high-revving AMG V8 naturally aspirated engine to breathe more easily and offered Formula-1 fans an even more emotionally charged sound experience.



                                Image Source: Mercedes-Benz

While the performance measures were unchanged from the commercially available car, there were other changes made, which are a pre-requisite for an exceptional Formula 1 Safety Car. The two centrally positioned green lights in the aerodynamically optimized light bar illuminated when the Mercedes-Benz SLS AMG F1 Safety Car joined the field and needed to overtake all the racing cars in front of it. Once the SLS AMG assumed the leading position, the outer orange flashing lights were switched on to signal to the Formula-1 drivers that no overtaking whatsoever is allowed. The white stroboscopic lights in the headlamps and tail lights perform a general signalling function in that they always flash whilst the safety car was deployed. A special number plate at the rear, with "Safety Car" lettering and 700 LEDs, provided additional safety in darkness or wet weather. A reversing camera was integrated to the left of the number plate, allowing those in the cockpit of the Mercedes-Benz SLS AMG F1 Safety Car to keep an eye on the Formula-1 cars behind via monitor.

Two central monitors in the SLS AMG cockpit were used to monitor the progress of the race. To the left and right of the lower monitor were the controls for the radio system, which allowed the driver and co-driver to communicate with Race Control as well as with each other. A second interior mirror allowed the co-driver to keep an eye on the Formula-1 cars behind. Meanwhile, the "Marshalling System" was integrated in the central display on the instrument cluster and in the lid of the glove compartment: here the driver and co-driver could see exactly the same signals as the Formula-1 drivers in their cockpits. For instance, the various LEDs indicate when yellow or green flags are being waved. LEDs indicating the status of the roof light bar, along with an on-board camera angled towards the driver are mounted at the front end of the dashboard.

4 Wheel Drive - The Mercedes Way

 
     (Image Source: Mercedes Benz.com)

In the mid-1980s the time was right to introduce four-wheel drive in other Mercedes-Benz passenger cars; to meet the requirements for saloon cars, however, it would be necessary to redesign the system.It was the anti-lock braking system (ABS) that had laid the foundations for this technology in 1978.

It formed the basis for acceleration skid control (ASR in 1981). It was followed by Automatic Differential Lock (ASD in 1985) and in that very same year, that the innovative 4-MATIC four-wheel drive system made its debut.

A common thread of these applications was that they registered and limited wheel slip with the help of the latest microelectronics and hydraulics, in order to improve the linear dynamics of an automobile. 4-MATIC was permanently active and distributed the drive torque between the front and rear axles during normal driving on a grippy surface. This maintained the dynamic advantages of rear-wheel-drive while giving the driver additional safety reserves.

4-MATIC was premiered in the 124 series in 1987. 4-MATIC showed its strengths particularly in unfavourable weather conditions such as wet roads, ice or snow, by ensuring exemplary handling stability and perfect traction. By providing traction on such difficult situations the permanent four-wheel-drive system supported the already outstanding handling characteristics of Mercedes-Benz passenger cars, also ensuring typical Mercedes safety and surefootedness when confronted with unusual dynamic requirements.

 Although the additional technology carried a small weight penalty and led to slightly higher fuel consumption, it proved extremely popular – especially in the mountainous regions of Europe and particularly North America.

 The 4-Matic went on to provide traction across the Mercedes-Benz product range. The S Class, The E Class, the baby C-Class all the three main saloons have benefited from the superior traction of the 4-Matic AWD system.

The latest in the prestigious lineup to benefit from the traction-enhancing feel of the 4-Matic system is the 2010 R-Class that is the newest model to be launched in the Indian Luxury touring class. Thus, the Indian customers are the chosen ones this festive season to experience the superior traction benefits while touring, the Mercedes-Benz way.

The 2010 Mercedes-Benz R-Class: A versatile answer to the Which Car? Query

                           (Image Source: RockingTeam.com)

The positive response to the new 2010 R-Class at the world premiere at the New York International Auto Show in March this year has convinced Mercedes-Benz that they have a winner on their hands. Featuring a redesigned front end to complement the over all look that is a tribute to the mercedes-benz saloons and suv's; the "twenty-ten" R-Class combines the spaciousness of modern day MPV's with the comfort, high-class appeal and prestige of classic Mercedes-Benz luxury saloons.

At the same time, this latest generation retains the interior versatility of its predecessor, whilst also benefiting from the robustness and all-wheel drive capabilities of the Mercedes-Benz SUV's. Thus, the 2010 R-Class combines the best of the Mercedes-Benz heritage and performance into one exciting all-round package.







 
                                   (Image Source:Google Images)


The Indian line-up features the R 350 4MATIC. Featuring a 3498cc V6 Engine with 272 bhp redlining at 6000rpm and 350 nm torque at 2400rpm this is one powerful beast. This engine is mated to the 7G-Tronic automatic transmission with a new torque converter that decouples at standstill. Such features help reduce engine stress, provide a quieter ride with smoother idling and reduced fuel consumption habits that make this vehicle a winner.

The designers of the 2010 R-Class were focused on providing an integrity of design while encapsulating the unique personality of this super-versatile vehicle. They have completely revamped the front end with a horizontally structured bonnet while making use of the extra width of the vehicle to give it a harmonious, powerful and well planted look. The side view with its flowing coupe like lines is a pleasant contrast to the existing MPV's in the market. The design idiom of the front is carried over to the rear section where, a new
bumper covering, modified tail-lamps and integrated tail-light trim help accentuate the squat, well planted look.


Once the designers were done with the exterior, they decided to focus on lavishing attention on the interiors. Working on a wellness program concept, they envisioned the R-Class interiors to be a relaxed environment for both, longer journeys as well as everyday use.

Touring with your loved ones is easy with the flexi-seating options. The R-Class can easily seat from two to 7 people while its luggage compartment can swallow 1950 litres of luggage with a separate stowage compartment under the load compartment floor.
 




                           (Image Courtesy: Google Images)
The R-Class has options like multi-zone 'Thermotronic' climate control system, 'Disctronic' proximity control system, memory function for the front seats, mirrors and steering wheel. The pilot in the captain's chair can control all the functions from the conveniently placed 'Comand' centre that places all the multi-media and sat-nav system.The bright, classic interior - which seems even more spacious when fitted with the optional panoramic glass sunroof - makes use of new materials and colour combination to enhance the high-class appeal and quality of this luxury tourer. At the same time they underline the sense of wellbeing inside the vehicle which is so typical of a Mercedes-Benz.

The R-Class provides the most comprehensive model range in the premium long-distance saloon segment. Together with the significantly more appealing body design, the complete range of standard equipment and the numerous individualisation options, the R-Class can be tailored specifically to meet individual requirements.

Indeed, if there was such a thing as a vehicle versatility test, then the R-Class would certainly be the favourite to
take first place.

'Shooting-Brake'

                                 (Image Source: Google Images)

In the olden days, carriages were used to ''break'' in wild horses and restrict (brake) their urge to move, before being used as work horses. Given the wild nature of the horses, carts that were not immediately in need were used for this task. Where necessary, "Brakes" were often fitted out with variable bodies, which were only really used to carry along anything that may have been necessary for the hunt, for example. Thus, the vehicles used when going out shooting were called Shooting Brake or Shooting Break.

The popularity of motorized shooting brakes was high in Great Britain, way back in the 1960s and 1970s. These were designed as exclusive cross-over vehicles, which combined the luxuriousness of a coupe with extended space on offer and additional variability.

Mercedes-Benz already had their CLS which still turns heads with its fascinating design and wows customers the world over. Mercedes decided to take the CLS design into the new decade with the announcement of the CLS Shooting Brake.

Based on the great tradition of stylish, cultivated sportiness in reverence to the great Mercedes coupes, the new CLS Shooting Brake takes this unique legacy an exciting step further. In addition, it also points the way towards the future design language that Mercedes is moving towards since the past couple of years.

Scheduled for introduction in 2012, the CLS Shooting Brake is yet another feather in the cap for Mercedes' premier plant in Sindelfingen. This model will be built on the same production line as the CLS and the E-Class saloon; where it will be joined by the Mercedes-Benz SL in 2014. This decision further underlines the significance of the plant as the competence centre for the luxury
class.

First the SLS AMG and now the CLS Shooting Brake. This exciting design philosophy reiterates the role of Mercedes-Benz as a leader in innovative passenger car concepts and design.

Gullwing Magic from the Three-Pointed Star

The origin of the legend has its roots in the early fifties when Mercedes were looking to regain their exalted position in motor-sports that they had held in the 1930’s. Those efforts bore fruit in the form of the 1955 Mercedes-Benz Gullwing Coupe 300SL.

                          (image source: themotorreport.com)

The brain child of development engineer, Rudi Uhlenhaut; the Mercedes 300 SL originally began life as a sedan, then morphed into a race car before being touched by Rudi, the automotive alchemist. Rudi and his team of magicians conjured up an intricate design made up of small tubes welded together. The team soon hit upon a roadblock, as the design of the frame left no room for traditional doors. This was in contravention to the race rules prevalent at that time, which stated that operational doors were a must on every race car.
                                  (image source: flickr.com)

Utilizing a loophole where the rules left out the detail over how the doors of a car should open; Rudi and his team came up with a solution that is celebrated by enthusiasts as one of the most iconic feature of the car in automotive history. The resultant “Gullwing Doors” became the most distinctive feature of the car. The single minded devotion to aerodynamic efficiency resulted in the absence of external door handles and even rear-view mirrors were post-factory add-ons. This design has gone down in the annals of automotive history and fans over the world have been clamoring for an encore.

The powers-that-be at Mercedes-Benz decided to delight their fans in the form of the Mercedes-Benz AMG SLS.


                                 (image source:dymee.com) 

Employing an aluminum space-frame, the entire body shell weighs in at a mere 241 kilograms. From the forged AMG wheels, the magnesium backrests and even the high performance ceramic brakes, the pursuit for weight reduction has been relentless. The construction of each and every component is closely monitored with wall thickness reduced in less stressful areas. Multi-part components are dispensed with to save weight; while simplifying the production process and reducing the burden on the environment.

All this has been backed by a high performance AMG heart supported by a dry-sump to help you slide out of those corners on the race-track without caring about any performance drops. Moreover, the flat underbody together with the underbody diffuser, help channelize air-flow to the seamlessly integrated rear aerofoil which is automatically deployed as you cross speeds over 120KMPH.

While all this technology helps you outperform the competition on the race-track, the AMG SLS is designed to pamper you off the race-track. The two-zoned seat cushions together with four-way lumbar supports cosset you for those long drives. To help serenade you further, the 11-speaker 1000-watt Bang and Olufsen Sound System provides you an exclusive listening experience at the highest level. And as you arrive at your destination, those alluring ‘Gull-wing’ doors and the shimmering ‘alubeam silver’ paint finish ensure that you remain the cynosure of all eyes.

The financials behind a new car purchase!

A common misconception amongst people is that of a new car purchase being cheaper than holding onto your old car.

Most people's knowledge of a new car's cost begins at the ex-showroom price and continues with the on-road price. What they fail to realize is that the true cost of a new car involves much more than just its purchase price.

To the ex-showroom price, one must add duties and taxes. Then comes the insurance cost. For a small hatch, these two components easily add up to around 40,000/- With the B-Segment offerings and those above, this amount keeps increasing.

But the biggest component and the one most neglected is Depreciation. A car is a depreciating asset and for the salaried class owner, Depreciation is the biggest value eroding component in a new-car owner's life.

A quick look at the used car price charts will give one a good insight into the depreciated value of cars in the Indian market. You will notice that the compact hatch segment depreciates the least while the depreciation increases in direct proportion with the size of the vehicle.

On the other hand, the European Marques see their value being eroded quicker than the Japs or the Koreans even in the A & B segments.

So, a new car does not make much economic sense especially in our example of Sameer Patel. So What then should Sameer do ?

Keep your 8 Year old Car or Replace it?

The festive season is just getting into high gear for the grand finale for the year. With Diwali being celebrated around the country starting today, its the time for shopping around. Tempted by mouth-watering deals and the sheer variety of cars on offer, a lot many of the new car buyers splurge on their cars during this auspicious time.

Which brings us to Sameer Patel. A banking executive in his late twenties who lives in suburban Mumbai. Having had a Zen in his family since the past eight years, he's now being harrowed by the 'Joneses' in his apartment complex to upgrade to snazzier wheels.

I'm sure that there must be more like Sameer in a similar predicament: Keep your 7-8 year old car or replace it!

Most petrol engines usually have a usable life of 2,00,000 kms. So long as the scheduled maintenance of replenishing essential fluids and other consumables is followed at the prescribed intervals, these engines are pretty happy to chug along.

Sameer's Zen is the MG410 engined carb version. Its clocked up 98,000 kms by now. In these eight years, the car has been cared for in the same garage at the prescribed intervals. Thus the cypress blue car has really been pampered with all essential parts being MGA OEM ones.

Today, she is looking her age. Her paint is not as lustrous. Various sounds are heard as she goes through her paces along the pot-holed roads of this city. Her suspension is making noises of the wrong kind, her fiber panels are rattling, the AC cooling is not as good as new. Besides, the entire She is in dire need of some TLC and a mid-life make-over.

Her list of woes seems to be never ending and what has aggravated her situation is the new-car scene currently.

Sameer has proved to be a fabulous employee and his company has rewarded him by fast-tracking his career in the past two years. He is also looking to ask his lady for her hand in marriage early next year. His folks are due for retirement by mid next year and his younger sister has just begun senior college. Thus, he is in a pretty stable position in life; both monetary as well as with respect to other responsibilities.

Further, he recently went on a drive with a colleague in his Ford Fiesta. Ever since then he has been thinking of upgrading from his Zen to a suitable mid-size alternative.

In the next installment, we shall take a closer look at the argument in support of a new car purchase.

Welcome to the Jungle!

Deep within the bowels of this amazing city of ours, there exists a green lung that is one of the most abused public spots. Officially it is known as the Sanjay Gandhi National Park. More commonly known as the Borivli National Park. An entrance gate that is dwarfed by a flyover, the park is a mere blur in the windows of the people zipping on that flyover.

For a select few, this park is one of the last remaining oasis in this concrete jungle of ours. The worst time to come visiting this place is on a Sunday, when the hordes amass upon this green lung and choke it to gasping point with their abusive ways.

The best season to come visit this place is from June to September. These few months, this place transforms into a magical world. A modern day, city version of wonderland. The sheer variety of colours on display make it a dream come true for every photographer/painter worth their salt.

During the rest of the year, it would be advisable to visit it during weekdays. If a weekend visit is unavoidable due to the rat-race, then its best to enter before 7 am so that you get 3-4 hours of peace before the rowdy picnickers invade the place.

Like a jewel with multiple sides, the park begins to reveal its secrets to those observant enough. Go take a walk in the park or pedal away to glory. Hit the toy-train to take a step back into time, when life was slower and simpler. If you feel its too kiddish for you, then get off it and follow the track as the train chugs away from you.

If the railroad is not up your lane, then get off the track and follow the path of the river that snakes its way through the park. Another alternative would be to walk down to the tourist information center and take off on a safari into the wildlife enclosure. Here you can get up close and personal with the lions, tigers and leopards that reside there. A note of caution here, although the animals here are well cared for, do not attempt to tempt fate unless you have nine lives to your credit.

By now you must be running a little low on energy and the first of the crowd invasion coming in. So, hop across to the restaurant across the entrance and refuel yourself for life in the concrete jungle.

A puncture-proof drive - The Holy Grail for Auto-Manufacturers.

Ever since the pneumatic tire was invented, tire manufacturers have been chasing the holy grail - a tire that never punctures!

So why then do companies chase such a mirage.

The answer is cost and performance gains. Confused...read on.

If a vehicle were to have tires that would never deflate, it would make the spare tire excess baggage. And the best way to performance gains and reducing fuel consumption would be to pare off excess weight. And it may not appear so, but the weight of a spare tire, the Jack and the associated mounting-unmounting paraphernalia do add up to the weight of a young child.

To the car designers, they could very well use all this space to provide a larger fuel-tank, a better suspension or just more boot-space. For the car user, he/she would be rescued from the chore of having to attend to a flat-tire forever. And to top it off, he/she could in theory get a more fuel efficient car/ a better performing one or just one with a larger boot to take in all the adventure equipment or shopping bags.

So why then are these tires not as popular as their regular tube-less counterparts!

The answer lies in the fact that tires are a huge factor in deciding how a particular vehicle rides or handles while out on the road and off it.

So far with pneumatic tires, by virtue of the time spent understanding them, the rubber-wizards have gotten pretty good in the dark art of churning out tires that are competent enough to handle the rough and tumble of the tarmac world.

For example, a stiffer side-wall reduces flex and thereby enabling it to grip the road and corner better. However, the same stiff side-wall ensures a jaw-breaking and harsh ride. On the other hand, while a soft sidewall will flex more, thereby ensuring a cushioned ride, it will reduce available grip. Similarly, a harder compound tire will wear slower and be less prone to punctures than a softer compound tire that would wear faster and be more prone to punctures.

The tire tech guys have become well accustomed to playing one parameter against the others to get the desired performance out of pneumatic tires as per the ride/handling brief. With Run-Flats however, it is still very early in the learning curve for them. This is reflected in the ride/handling performance of the vehicles shod with run-flats and the opinion of customers the world over.

In India, the situation becomes even more peculiar. Run-Flats traditionally have a stiff side-wall and flex much less in comparison to pneumatic tires. In addition, their construction affects their ride quality in a negative manner. Besides, with the still 'under-development' nature of the road infrastructure, vehicle manufacturers are traditionally expected for setting their vehicles up in comfort-mode. To add to this, RFT's in their current stage of development cost a bomb to replace, which becomes a necessity if they deflate and are driven on.

Some, if not all of these reasons have led to two of the big three Luxury Manufacturers in India - Audi and Mercedes Benz, from offering Run-Flat Tires as OEM on their cars.

Which brings us to the remaining luxury manufacturer - BMW Motors, makers of fine driving machines that traditionally have good handling at the cost of ride quality.

BMW so far have been zealous in their promotion of RFT's on their cars. The reasons behind such a move baffle this humble tarmac worshipers mind and leave him wondering behind the premature decision to force such an ill-suitable and yet-to-be-developed technology down the pockets of the help-less Indian Luxury Car Buyer.
