DETROIT -- Cadillac's 2016 CTS-V -- the third generation of the track-ready midsize sedan -- will shoot from 0 to 60 mph in under four seconds and hit a top speed of 200 mph.
The car's 6.2-liter supercharged V-8 engine will produce 640 hp, up from 556 hp in the last generation, which was phased out this year. Torque is rated at a whopping 630 pounds-feet, about 100 more than the Mercedes E63 AMG.
Power will be transferred through General Motors' homegrown eight-speed automatic transmission with paddle shifters.
Cadillac's V series gave the brand some much-needed credibility when it debuted in 2004, first on the CTS sedan, and later on coupe and wagon variants. The new CTS-V will compete with the E63 AMG and BMW M5.
The car represents "the most compelling example of Cadillac's product substance and brand trajectory," Cadillac President Johan de Nysschen said in a statement.
The '16 CTS-V has distinct sheet metal from the cowl forward, compared with the base sedan, including a carbon fiber hood and larger, mesh grille opening to cool the bigger engine. Performance enhancements include a new version of GM's magnetic damping system that responds to road inputs 40 percent faster, engineers say.
Inside, the car is blanketed in suedelike microfiber and has Recaro racing seats and a performance data recorder that records high-definition video of drivers' experience.
Production is scheduled to begin this summer.
Near-term plans do not include a coupe or wagon, but Cadillac is expanding its V series offerings with the introduction of ATS sedan and coupe versions, which arrive this spring.
