Why F1 hopes its new-look 2022 car is a game changer – ESPN

New year, new rules, new look. After one of the most exciting seasons in its history, Formula One is due to make one of the biggest regulatory shakeups for decades.

Why change the regulations?

The overhaul of Formula One’s technical regulations for 2022 is so extensive that it’s easier to list the parts of the car that aren’t changing than the parts that are. Having said that, the cars that line up on the grid for the first race in March will still be instantly recognisable as Formula One machines, although the shapes and philosophies that make up the designs will be a significant departure from the ones that crossed the line at the final race in Abu Dhabi last year.

When Formula One and the FIA, racing’s governing body, first set out to create the new set of regulations in 2017, there was one main aim: improve wheel-to-wheel racing. Factors such as aesthetics and cost were also part of the equation, but the overarching purpose of every article in the 2022 technical regulations is to increase the chances of overtaking.

The problem F1 was trying to overcome was well known from the get-go. For years, drivers complained about a loss of downforce while following another car, making it difficult to plan and execute an overtaking move as they lost cornering performance the closer they got to the car in front.

The reason for the problem was also understood: the aerodynamic surfaces of a Formula One car are designed to offer as much downforce as possible as air passes over them, but the design process to reach those surfaces assumes the flow of air is clean and constant. As soon as another car runs in front, it disrupts the flow of air over those aerodynamic surfaces and makes them less effective, reducing the cornering performance of the car.

F1’s studies found that a typical car built to last year’s regulations would only retain 53 percent of its peak downforce once it is running within a car’s length of a rival. This loss of downforce makes it almost impossible for cars to race closely through high-speed corners where downforce is essential to performance, significantly reducing the chances of overtaking at certain tracks.

The new regulations are written to tackle this problem at the cause, and simulations of the new designs suggest cars will be able to retain as much as 82 percent of their downforce while following within a car length of a rival. Whether that 82 percent figure is accurate once teams have tweaked every last surface of the car to work to their advantage remains to be seen, but it’s hard to argue with the theory behind the rule change.

NASCAR’s Symmetrical Next Gen Cars Are Getting Skewed In Practice – Jalopnik

NASCAR’s newest Next Gen cars may be designed to make these vehicles as symmetrical as possible, but some teams have already found a way around the rules. During this week’s test session at Daytona International Speedway, some cars have been running some fairly excessive skew — and right now, it could very well be totally legal.

Basically, skew refers to the angled nature of the NASCAR Cup Series car. The front end looks like it’s pointing in a different direction than the car is actually going, which gives the whole thing a sort of crab-walk look. The rear axle is mounted on a skew when compared to the whole chassis. For…….


Is Norway the future of cars? – Kathimerini English Edition

The speed by which electric vehicles have taken over Norway has stunned even the cars’ enthusiasts. [Asya Demidova/The New York Times]

Last year, Norway reached a milestone. Only about 8% of new cars sold in the country ran purely on conventional gasoline or diesel fuel. Two-thirds of new cars sold were electric, and most of the rest were electric-and-gasoline hybrids.

For years, Norway has been the world leader in shifting away from traditional cars, thanks to government benefits that made electric vehicles far more affordable and offered extras like letting electric car owners skip some fees for parking and toll roads.

Still, electric car enthusiasts are stunne…….
