When Cadillac introduced the 2016 ATS-V in coupe and sedan guise, we were promised 455 HP and 445 lb-ft (603 Nm) of torque from the twin-turbo 3.6-liter lump. That output hiked to 464 HP months after the BMW M3/M4-rivaling Caddy debuted, but this might not be the end of the ATS-V’s quest for power.
As if a 0 to 60 mph (96 km/h) stint of 3.8 seconds (4.1 for the automatic) wasn’t enough performance to pose a threat to the M division, Cadillac engineers could get berserk with a future iteration of the ATS-V. MT’s Mike Connor reports that the Cadillac ATS-V+ will make use of the naturally aspirated LS7 big-block V8 that’s used by the fifth-gen Chevrolet Camaro Z/28 track monster.

Without citing any source or “a man on the inside,” the motoring publication is adamant the 7-liter tower-of-power will animate the ATS-V+ model. Though many of us were expecting the ATS-V+ to be offered with a downtuned LT4 from the Corvette Z06/Cadillac CTS-V, MT makes a case in point: “GM wants its high-revving naturally aspirated eight-cylinder to live on, so it's keeping it in production for the Cadillac ATS-V+.”

With 505 horsepower and 481 lb-ft (652 Nm), the LS7 is a pivotal point of the Z/28’s track-oriented package. It’s mum’s guess whether this rumor will see the ATS-V+ whoop some Bavarian ass in the guise of the BMW M4 GTS. The latter is expected to debut this August at Pebble Beach, water-injection included.

Expected to come with an 8-speed automatic and C7 Corvette-derived 7-speed manual, MT is hinting towards a third transmission option - “a quick-shifting dual-clutch gearbox.” The Chinese-spec 2016 Chevrolet Cruze is available with a DCT, but we have our reservations regarding a strong enough dual-clutch transmission for the LS7 V8’s ample torque. Then again, will the LS7 V8 fit the engine bay of an ATS-V?

UPDATE: speaking to MotorAuthority, Cadillac communications manager David Caldwell makes it rather clear the LS7 in an ATS-V is a pipe dream: “The ATS-V we have today is supremely capable—so much so that it’s unlikely to receive a larger, or different engine in the foreseeable future. As for V-8 engines, yes, we have another car coming that will take care of this beautifully, that being the CTS-V. The obvious question is, 'why not' have V-8 power in both? The answer is that there’s no need for the two V product lines to be twins. Brothers, yes. Twins, no. This new era of V-Series gives us the chance to dial-in two types of performance character—both track capable, both premium. One is smaller, a little more approachable (relatively speaking) with the most powerful V-6, the Cadillac Twin Turbo. And its big brother coming later this summer with a supercharged V-8 with authoritative power.” Dear folks from MotorTrend, you were wrong on this one. Badly wrong.
