Here's what's new in the Hyundai Genesis coupe

Hyundai has made a few tweaks to the Genesis coupe for the 2014 model, following a major redesign for 2013.

Perhaps the biggest change to the Genesis coupe's drivetrain for the 2014 model year is a downshift rev-matching system, which has been standard for models equipped with an eight-speed automatic transmission.

Hennessey Performance upgrades the Ford Mustang Boss 302

We should get to drive one of them sometime before the fully finished models go on sale next summer and then we will have a more definitive take on the car.
