If you haven’t yet heard, rumor has it that Cadillac is working an ATS-V+, an even more hardcore version of the high-performance ATS-V. The vehicle is said to cradle GM’s naturally-aspirated, high-displacement 7.0L LS7 V8 engine for one heck of a high-performance compact luxury sedan and coupe. But what advantage would an LS7 have under the hood of the ATS compared to the twin-turbo 3.6L LF4 V6 in the “regular” ATS-V? In one word, a lot.
For the sake of figuring out the advantage of the LS7 in the rumored ATS-V+, we’re going to assume the following three things:
- An ATS-V+ is actually on the horizon
- The rumored ATS-V+ will cradle GM’s LS7 V8
- The LS7 will beastly seven liter will make same amount of power in the ATS-V+ as it did in the C6 Corvette Z06 and in the fifth-generation Camaro Z/28
With those assumptions in mind, the advantages are quite clear: the ATS-V+ would have 41 horsepower and 36 pound-feet of torque more than the “regular” ATS-V. Plus, the ATS-V+ would likely weigh less than the ATS-V, since the LS7 is lighter than the twin-turbo LF4, further increasing the capability of the already-capable ATS-V.
And if that doesn’t tickle your fancy, then we should also note that the LS7 would also make that brawny burble-gurgle sound. Mate it to a seven-speed manual or eight-speed automatic along with the ATS’ already-excellent handling and vehicle dynamics, and we finally have proof that there can be such a thing as automotive perfection.
|VEHICLE:||2016 ATS-V 3.6L TT LF4||RUMORED ATS-V+ 7.0L LS7||ATS-V+ +/-||2015 BMW M3/M4|
For the sake of comparison, we also threw in the BMW M3/M4 into the chart just to see how much the ATS-V already blows it out of the water, and how much the ATS-V+ will do so even more.
