A couple of weeks ago, I made a post about a recent Motor Trend test of the Lincoln MKZ lineup. In that post, I suggested that the testing itself was hurting Lincoln's image. The vast majority of the review was about performance numbers and that doesn't seem to be what Lincoln is after so, naturally, Lincoln cars don't put down numbers you can brag about. They're simply adequate. That doesn't necessarily mean they are bad cars though. For example, if someone were to take a Rolls Royce Phantom Coupe and compare its performance to a new Corvette Stingray Z51, the Phantom would come up really short. In reality, the Phantom Coupe is very far from bad or even average. It's simply not a performance car. In fact, it's so far from a performance car and offers so much more luxury and brand prestige than a Corvette that they would never be cross shopped, but you get the point. If you use the Corvette yardstick, the Rolls Royce would come up short. The opposite
BMW M2 equipped with an eLSD - BMW © A few weeks ago, I posted about traditional clutch-type limited slip diffs (LSD's) and how they work. You can read about those in the previous post: How Limited Slip Diffs Make You Faster on Track . 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
