Dismissing six cylinder cars as weak attempts at performance no longer applies. Buick guys have known this for decades, the Mustang guys started picking this up a few years ago, and Cadillac has recently gone for the full-on bonkers platform with the ATS-V, sporting a twin-turbocharged and intercooled 3.6L V6 that thumps out an impressive 464 horsepower. It might look like a small luxury car, but the Caddy will knock a very low 12-second pass straight out of the box. That’s fast, period, and for an engine that only has 217 cubic inches, that’s solidly impressive.

But for some, that just isn’t enough. Take this ATS-V coupe: with a down pipe, and X-pipe, and a 93 octane/meth tune, it is now cranking 545 horsepower at the wheels. That’s really not that much work to get an ATS-V to belt out a quarter-mile blast of 10.92@126 miles an hour. You might not appreciate the noise it makes…that exhaust note isn’t my favorite, either, to be honest…but the noise doesn’t mean a thing when it hustles around like a well-sorted big block!
