Audi Sport has just launched new generations of its RS 6 Avant and RS 7 Sportback but details about more potent Performance versions coming down the line have surfaced. Expect the future Performance versions to come with plug-in hybrid technology and outputs approaching 700 horsepower.

Aston Martin's DBX is in the final stages of development and a prototype has just been spotted. The SUV will be revealed in December but won't be in production until next summer. Our latest spy shots show the final body shape and some of the interior.

Following the reveal of the CT4-V earlier this year, Cadillac has now shown us the standard version of its entry-level sedan. There's nothing entry-level about the CT4, though, as even the base model comes with close to 240 hp.
