The Cadillac ATS-V needs to bring the power to put the BMW M3 away. The Cadillac ATS-V will bring an exciting engine for the new Cadillac track star — we just don’t know which one yet.
The Cadillac CTS-V uses the LSA supercharged 6.2L V8. This engine makes 556 hp in the CTS-V. The Camaro ZL1 uses a modified version of the LSA engine, tuned to 580 hp. We may reasonably see this modified variant in next year’s redesigned CTS-V as well, at 580 hp.
The Camaro ZL1 is down on power compared to its arch rival the GT500, which makes 662 hp. The ZL1 is a better overall package, but I am hoping GM Powertrain brings the power for the next iteration of the LSA and hits 700 hp. A powered up CTS-V also gives more head-room for a powered up ATS-V.
Cadillac ATS-V – Turbo V6?
The ‘missing’ engine is the Turbo 3.6L coming as an engine for the 2014 CTS. We don’t know the exact output for this engine yet, and it will likely arrive in several states of tune. Rumors have been all over the place — 450 hp for an initial show car, down to 425 hp for production, and up to 475 hp.
A maximum effort ATS-V version of a turbo V6 engine could be tuned for 480 hp and still leave room for a slightly heavier CTS-V with a 580 hp V8. But besides avoiding sibling rivalry, will that be enough for the Cadillac ATS-V?
Sizing the Competition
How much power does the Cadillac ATS-V really need? The 2014 BMW M3 is the logical target. The current M3 uses a 414 hp V8. The next M3 is rumored to equip a tuned turbo V6, for 430-450 hp. BMW manages to under-rate their engines; so when matching it is best to plan for an extra 25-35 hp for equivalent. A good target for the Cadillac ATS-V powerplant then is BMW 450 +30 equivalent + 50 better or 530 hp.
And ding ding we have a 556 hp LSA engine available that can be slotted for the ATS-V. Give the CTS-V a power-up to a 650-700 hp version that the Camaro ZL1 needs, and there is head room to give the ATS-V the current LSA.
If GM Powertrain can bring the same power range (500-530 hp) in the Turbo V6 of course, all the better…
