The official performance specs of the 2015 Ford Mustang’s engines are in, and it looks like power is up across the board. The most potent is the Mustang GT, whose V-8 is rated at 435 horsepower, but unfortunately it weighs a hefty 3,705 pounds.

Mercedes-Benz is almost ready to show off its all-new C63 AMG. Today we learned that there will be both a standard model and extra potent S model. The latter is said to have as much as 503 horsepower.

Nissan’s autonomous car due in 2020 won’t be fully autonomous, the automaker has confirmed. It will be able to navigate certain situations by itself, though a driver will likely need to remain in control most of the time.

You'll find all of this and more in today's car news headlines from around the High Gear Media network, right here at Motor Authority.
