What is the difference between nascar cars

Aero, brakes and the suspension settings can all depend on the type of track being raced on. The current Generation 6 car in the Sprint Cup debuted in , with the major changes being to the bodywork. The front-engine, rear-wheel-drive cars are said to be based off current road car models — the Ford Mondeo Fusion , Toyota Camry and Chevrolet SS — but the only real similarity is the look.

This was brought in for the Generation 6 car through improving the visuals of the cars to make them better resemble machines on the road, as well as helping to differentiate the manufacturers involved. There have been some changes for , with rear spoiler heights decreasing from six to 3. This is one of the few pieces of aero on the cars. Front splitter leading edges and radiator pan widths have also been reduced to make cars trickier to drive, while gear ratios have been adjusted to maintain a maximum rpm engine speed in top gear.

The Truck series is the bottom tier of the national Nascar division, below the Xfinity series and the top championship, the Sprint Cup. It is the only series that races modified pickup trucks, with its inaugural season taking place in , 46 years after the first campaign for top-line stock car racing in the USA. While the Sprint Cup races on a mix of ovals, as well as two road courses, the Truck series is predominantly on intermediate oval tracks, with a few speedways, short tracks, road courses and dirt tracks in the mix too.

The season will be spread over 23 races, with a similar play-off system to the Chase for the Sprint Cup being adopted for the final seven rounds. Many races of the series support the Sprint Cup, but some do take place on different weekends and at different race tracks. Many top drivers have come through the championship and gone on to success in the next two tiers.

Over the years, more and more modifications have been allowed slowly increasing the performance of the cars over the years. The overall shape of each of the cars, the tires, suspensions, fueling systems, electronics, and transmission are all the exact same. Racing teams are able to reuse these parts and some elements are allowed variation. For example, the block and cylinder heads of the engine can be remachined within a range of certain tolerances.

The tolerances for piston ring gaps and bearings are the only pieces that engineers did not have to follow any NASCAR regulations on. In terms of quantitative regulations for the engine, all engines have to feature a cubic inch 5. The current regulations on horsepower for NASCAR is hp on tracks shorter than one mile and just hp on tracks longer than 1 mile.

NASCAR prohibits the use of turbocharged engines and no car has ever used one in the history of the sport. This is largely due to turbo lag which can result in the engine delivering instant power likely leading to an error or crash. This kind of design in tires gives more surface areas for the tires to be driven on a dry track, which provides a better grip on the road. Terms and Conditions - Privacy Policy. Compare Cars.

Hybrid engines are those that are powered by a combination of both fossil fuels like gas and electric energy. Notably, all three engine suppliers have been investing in extensive research into electrical engines the last few years, and sell cars with hybrid engines. Toyota, Ford and Chevrolet would all be making engines for NASCAR that are more similar to what they sell to their customers, and to what the future of cars look like.

The shift to hybrid changes has been happening in other motorsport categories as well, with Formula 1 having hybrid engines since , and Indy car planning a similar shift. The change also makes sense from an environmental perspective; hybrid engines are more environmentally friendly, as they pollute less. Making less damage to the environment is crucial for NASCAR's and all of motorsport's long run success, which also helps explain the transition to hybrid engines.
