They've finally posted it! The 2013 Lightning Lap feature is finally available online (full article: Lightning Lap 2013: Hot Cars, Hot Track, Hot Laps ).

But as you might know or have learned from reading the article, they aren't without their faults, which means engineers are always working to get around those limitations. You may not be surprised to learn that something like the Ferrari 488 GTB doesn't use a traditional limited slip diff, but it's not limited to super cars, far from it. Cars like the Golf GTI, the Civic Type R, various Mustangs, Corvettes, and BMW M cars, and even the Lexus RC F and GS F, all avoid a traditional limited slip diff in favour of one of these technologies. To keep things simple, I'll focus on two wheel drive vehicles. The vast (vast) majority of principles apply to all and 4 wheel drive vehicles, but there are some subtle differences that I'll
