 Covini C6W 2011

The original idea for the Covini C6W was conceived by Ferruccio Covini in '74 and made provision for 10 inches front wheels because there where no low profile tyres at the time. The project was ditched in favour of the Soleado prototype, deemed more important, and lay dormant until the 80s when hydro-pneumatic suspension for the four front wheels where devised to optimise weight distribution under various loading conditions. High development costs and other contingencies forced the project to be delayed again. Its use of new ABS technologies and airbags in the 90s pointed in the direction of new research into active and passive safety. This aspect encouraged backing from companies for its development.

Why six wheels?

• in case of a front tyre deflation, the vehicle control is guaranteed by the other wheel next to it.
• our front disc brakes, although a smaller single area, ensure a greater braking surface; this means less overheating and a higher brake effort
• low risk of aquaplaning, due to the two foremost wheels, which wipe the water for the ones behind them, ensuring a better roadholding
• comfort is a consequence of more evenly distributed reaction forces in the supension: the reaction in case of a pot hole is divided between the four front wheels and the shudder in the chassis is limited.
• reduced unsprung weight in the wheels improves the grip. Directional stability is improved: a change of angle due to slack in the steering mechanism (in stuctures like silentblocks) is compensated by the second set of wheels.
• two additional springs and dampers provide a better handling for the vehicle.

Nissan GT-R - The Epoch-Making Car

By Chris Cornell

When the Prince Automobile Company merged with Nissan-Datsun in 1967, it gave way to the beginning of new GT-R legend series. Though the super car came from the humble Nissan Skyline family saloon, it was right at the time when the FIA GT series was making waves in the market. Nissan wanted to take on the Porsche 904 in the Japanese Grand Prix since the earliest predecessor of the GTR, the S54 2000 GT-B, came second in the very first race in 1964. So in 1969, Nissan premiered its first race-spec GT-R and it overtook the Porsche 904 in the race. That was the beginning of the legend of the GTR Skyline.

Nissan rolled out the next generation of the GTR, a four-door sedan PGC10 2000 GTR. It was good enough to achieve 33 victories in a short span of one and a half year. In 1972, the Skyline GTR, which had 1000 victories, was discontinued by the company. The next year, it brought out a better version of Skyline GT-R, a 2-litre engine driving the rear wheels. The production was suddenly stopped in 1977 due to poor sales. The last of the original GTRs from the Nissan saloon was the KPGC110 2000GTR. But it was never used for race and is still kept at a unit as historical reference in Zama.

The setback of 1973 Skyline GT-R, which was powered by a 1989cc engine, was due to the oil crisis and it smothered the enthusiasm for high-performance cars in the market. Sixteen years later, in 1989 the new GT-R version of Skyline with advanced technologies like four-wheel drive system 'Attesa-ETS' and the Super-Hicas four-wheel steering was launched. It progressed from 1989 until 2002 in R32, R33 and R34 specifications. In 2007, Nissan displayed a redesigned concept. The new Nissan GT-R was based on this concept and did not carry the Skyline badge. Thus the Nissan Skyline GT-R, which has achieved great success on the race track, is still forms the heritage of Nissan.

In 2009, the Nissan reached an agreement with Federation Internationale de l'Automobile GT Championship (FIA GT1) to fine tune its performance to market the car to racing team. And in 2010, Nissan was declared the Official Vehicle Supplier for the new FIA GT1 World Championship in which it will supply four GT-R cars for each SRO event and one of its high performance vehicles will take the Official Safety Car role at each event.

Renault Dealer - Make Sure You Choose the Right One

By Pete Ridgard 

There are few vehicles in the world today that have as storied a history across Europe as the Renault. Founded in the late 1890s, Renault has set the stage for many car companies that came later. Pioneering superior engineering, craftsmanship and design, there are few vehicles -- and car companies -- that can even begin to compare to the superiority of a Renault. As such, when you are in the market for a new car, you need to make sure that the Renault dealer you choose to buy your new car from, is just as superior as the products they are selling.

Your Renault dealer should be professional, courteous and have the proper product knowledge so that no matter what question you can think to ask, the answer will be forthcoming and correct. Additionally, the dealership from whom you purchase your new vehicle should also have a great supply of the newest and hottest Renault vehicles from a hatchback to a coupe to everything in between. By offering their customers a great selection of these top of the line vehicles, it can set any given dealer apart from their competition. Too, service after the sell is also going to be one of the factors that sets dealerships apart from each other. It is important to find a dealer that is not only reputable, but one who is also superior in their customer service. It is the combination of both of these aspects that is going to propel one dealer over the other and create an atmosphere where customers can be delighted by the attention to detail and superior product selection.

Your Renault dealer should also have a reputable and trustworthy mechanic employed on site. The fact of life is that cars -- no matter how well built -- will need to have checkups from time to time to make sure they are kept in a perfectly running condition. Taking your vehicle to just any mechanic who may not be certified for the type of car you have is not a wise idea as they can actually do more damage to your engine and operating systems than not.

This is not to say they are bad mechanics, just that they may not have the experience in working on your particular type of vehicle, this is why it is important to be able to take your car to the mechanic at the dealership to ensure the proper parts are used should you find yourself needing maintenance. All in all, the things you are looking for in your new car -- reliability, superiority and reputation -- should also be used when determining which Renault dealer you should choose to buy your new car from.
