New vs Used: Mercedes-AMG C63 Coupe vs BMW M6 Competition

Power is addictive. And a budget of $150K yields a wide selection of ways to feed the habit.

You can score a HSV GTS with 430kW and $50K worth of change. Or, for less of a discount, Lexus’s RC F offers 351kW of high-tech atmo grunt.

However, if you prefer power in a more sophisticated package you should turn to Germany. Your mates at the pub might scoff at the smaller, turbocharged engines the big three are bolting together, but they won’t be so smug after hearing the sort of numbers these engines make.

Mercedes-AMG’s C63 S manages to extract 375kW and 700Nm from a measly 4.0-litre V8. And if you needed any indication there’s some headroom left, the similar engine in the incoming GT R makes 430kW.

By all accounts, the new twin-turbo unit matches the old 6.2-litre atmo V8 in all facets. You’ll need to creep above our $150K budget to have one in the sleek coupe, which isn’t the prettiest body style around. Although as with most things, there’s an alternative to that in the classifieds.

BMW’s M6 is a looker and limbos under $150K thanks to the depreciation devil. We’ve found a 2013 example for $139,980, which is on the spectrum’s cheaper end, but shows how far it’s come from the original $300K price tag. For that, though, you’re up 37kW on the C63 S and given an extra 400cc. Sure, it has 20Nm less, but we wouldn’t be surprised if BMW’s been conservative with the M6’s outputs, as its rolling acceleration is phenomenal.

The chassis isn’t as agile as the Merc’s, and with older M6s exiting their warranty periods about now, make sure you ask for a full and detailed logbook. However, the upside is that modifications are now kosher. We’d opt for a proper exhaust, too, because like we said, power’s addictive.
