Cadillac’s award-winning ATS sedan is about to spawn a high-performance variant, and a prototype has been spotted at the Nürburgring. The car is the all-new ATS-V, which will join the upcoming ATS-V Coupe and CTS-V in the American luxury brand’s high-performance lineup. Designed to rival the likes of the BMW M3 and Mercedes-Benz C63 AMG, the new ATS-V looks very fast as it carves up the ‘Ring in our latest spy video—and the sound it makes is very aggressive.

We’re expecting both this ATS-V sedan and the ATS-V Coupe to be launched on the market late next year, as 2016 models. The two cars will be almost identical, though obviously the ATS-V Coupe will feature two doors. The ATS-V Coupe will also be slightly wider, as the regular ATS Coupe is already 0.8 of an inch wider than the regular ATS sedan.

Though it’s yet to be confirmed, power in Cadillac’s new ATS-V models is expected to come from an uprated version of the twin-turbocharged 3.6-liter V-6 found in the current CTS and XTS Vsport. It appears a previously-rumored V-8 option has been ruled out, although we hear the new ATS-V models will come in both standard form and more potent ‘Plus’ trim, with the latter possibly getting a V-8.

Peak output is expected to lie somewhere close to 425 horsepower in standard form, which matches the output of BMW’s new M3 and M4 models but is less than the output of the Lexus RC F and likely that of the next-generation C63 AMG. One key advantage of the ATS-V models is their lightweight Alpha underpinnings. The ATS-V models are also thought to benefit from a seven-speed manual transmission as standard, with General Motors Company's [NYSE:GM] brilliant eight-speed automatic available as an option.

On the outside, the ATS-V models will feature an aggressive look at the front, dominated by a unique grille with vertical slats. Steel brake discs are present on this prototype, and at the rear we see a set of four large exhaust tips integrated into a diffuser. On top of this appears to be a chunky trunk lid spoiler.

A reveal should take place soon.
