For the first time, the top performance option for a Porsche model line is a hybrid, in this case the Panamera Turbo S E-Hybrid. The super sedan combines a twin-turbo V-8 with an electric drive system for a combined 680 horsepower, and we’ve just driven it.

If you prefer old-school grunt, Ford has an updated Mustang GT on the way, and it has a naturally aspirated V-8 delivering 460 hp.  It has some interesting tech, too: a programmable exhaust system that allows you to choose which hours you want your exhaust at its loudest.

Audi is working on its first-ever RS 5 Sportback, and we’ve just spotted a test mule. The good news is that since the latest A5 Sportback is being sold in the United States, we should see the RS 5 version as well.
