Cadillac is seeking some much-needed momentum for its entry-level ATS nameplate with the launch next spring of V series track-ready versions of the sedan and coupe.
The 2016 ATS-V models, unwrapped Tuesday at an event on the eve of the Los Angeles Auto Show, will be powered by a twin-turbocharged V-6 engine rated at 455 hp and 445 pounds-feet of torque.
It's the same engine that GM introduced last year in the CTS and XTS Vsport sedans.
GM said the ATS-V models will sprint from 0 to 60 mph in 3.9 seconds and achieve a top speed of 185 mph. The engine will be coupled with a six-speed manual or eight-speed automatic transmission with paddle shifters.
GM will begin production of the cars in the spring, the company said in a statement.
Cadillac introduced the V series in 2004 on its CTS sedan, and later rolled it out to the coupe and wagon. GM has said V series sales account for about 8 percent of overall CTS volume.
