Since the launch of the Cadillac ATS, we’ve waited with baited breath for an ATS-V. Now, we can share some details, and they’re better than you could hope. Yes, Virginia, there will be an ATS-V, and it will be powered by Cadillac’s twin-turbo 3.6-liter V-6 making 425 hp.
Better yet, it’s slated to get a seven-speed manual gearbox option. Even better than that is Cadillac's plan for an ATS-V+, which will get an even more powerful V-8, and could arrive as soon as 2017. Could the V-8 be the new supercharged, "625+ hp" LT4 from the 2015 Corvette Z06? We sure hope so. What's not getting the LT4 is the new Cadillac CTS-V. Instead, it gets a new twin-turbo version of the Corvette’s LT1 V-8, an engine that's also slated for the next Corvette ZR1. Additional plans call for seven-speed manual, an eight-speed auto, and a dual-clutch transmission, though that quick-shifting gearbox probably won’t arrive until early 2015. In all, the ATS family appears to be filling out quite nicely. The 2015 Cadillac ATS coupe, made its debut at the 2014 Detroit auto show, with the two-door sporting sleek lines and Caddy's new badge that ditches the wreath. Like the sedan, the ATS coupe is offered with the turbo-four and V-6 and rear or all-wheel drive. That said, expect the V treatment to carryover to the two-door ATS as well."
Leaving off the ZR1 talk because it's way too early to discuss that, this is absolutely FABULOUS news for us E9X M3 owners who don't want to give up the V8 in search for our next cars. All Hail the ATS-V+!!! (actually I think the V8 version will just be called "ATS-V" whereas the 3.6 TT version will be called the "ATS V-sport" like its CTS cousin)
