Mercedes-AMG’s S63 has been updated along with the rest of the 2018 Mercedes-Benz S-Class range. Chief among the updates for the S63 sledgehammer is a new, more powerful V-8 engine.

Dodge has just unleashed its 2018 Challenger SRT Demon and Texan tuner Hennessey has already promised modifications to almost double the car’s output. We’re talking upwards of 1,500 horsepower.

A new generation of the Bentley Continental GT is just around the corner. The redesigned model will be sportier than the outgoing car thanks to a platform developed by Porsche. Our spy shots suggest it will look better, too.
