The 2016 ATS-V Coupe has already leaked to the web but that hasn't stopped Cadillac from releasing another teaser video for the BMW M4 competitor.

In the latest clip, we can see a heavily camouflage prototype accelerating on a track. The video doesn't reveal much but we can hear the tell-tale sound of a manual transmission and a rather dull exhaust note.

As we have previously reported, the ATS-V Coupe will feature a twin-turbo 3.6-liter V6 engine that develops 450 bhp (335 kW) and 445 lb-ft (602 Nm) of torque. It can be connected to a six-speed manual transmission or an optional eight-speed automatic.

The car will debut at the Los Angeles Auto Show on November 18th, so stay tuned for full details.
