2016 Cadillac CTS-V Sedan spy shots

If you thought Cadillac was content to leave its twin-turbocharged Vsport as the range-topping CTS, think again. Behold, our first good glimpse at the next-generation Cadillac CTS-V sedan, sporting more aggressive styling (somewhere under there), meaty quad-exhaust pipes, and what very well could be a new face for the V-badged Caddies.

Creating an all-new grille design seems like an awful lot of work just for a prototype, so it's very possible that the vertical-bar treatment you see here could make its way into production. Our spy photographers have pointed out that they've seen this same sort of grille treatment on prototypes for the smaller ATS-V sedan, and we've heard V-series models may soon have greater differentiation from the standard vehicles that sired them – that seems especially necessary if Cadillac insists on expanding this whole Vsport range.

Regardless of how its front end looks, the CTS-V ought to be a real monster. Industry sources say we can expect to see a supercharged version of General Motors' 6.2-liter V8 under the Caddy's hood, and considering the current car already makes 556 horsepower and 551 pound-feet of torque, we wouldn't be surprised to see a decent increase in both of those numbers. After all, one of the CTS-V's main competitors, the Mercedes-Benz E63 AMG, is currently putting out 550 hp and 590 lb-ft of torque. Could this mean a 600-hp Cadillac is on the horizon?

Despite the CTS-V being in prototype stage, we're still over a year away from seeing the production car. Expect it to show up sometime in the 2015 auto show season as a 2016 model.
