Well, it's this time of the year again for Motor Trend's Best Driver's Car feature. The full feature and the drag race is not available yet but quick reviews have been posted for the contenders as well as lap times (everyone loves lap times, right?). I will post a rundown of the cars that surprised and disappointed me the most when the full reviews are available but for now, enjoy the above car introductions and specs as well as hot laps and lap times around Mazda Raceway Laguna Seca. I have posted the most recent video, which is of the 2015 Nissan GT-R Nismo. From there, you can go back through videos by clicking on the video insert next to "PREVIOUS VIDEO" or "NEXT VIDEO" between the 2:30 mark and the 2:40 mark depending on the car's lap time.

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
