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 ...
C7 Corvette Grand Sport... doing a burnout with a proper diff - Graham MacNeil © I wrote a tech post comparing various open and limited slip diffs for a comparison and I found that a lot of people were asking questions. To simplify and make it easier to read, I decide to break them up for a future tech article about handling. Make sure to stay tuned for two posts on limited slip diffs this week!. WHY DO YOU EVEN NEED A DIFFERENTIAL? A differential's job is to allow two wheels on the same axle (or two axles in a 4WD drivetrain) to spin at different speeds so a car could smoothly go around a corner. Why do the wheels need to spin at different speeds? Each wheel on a car has to travel a different path to reach the end of the turn. You can see that for yourself every time you drive on snow covered roads or muddy trails.
