Nestling in-between the regular Audi A6 and the potent RS6, the 2020 S6 borrows a little from both. On the one hand, it’s a luxury sedan with all the expected trimmings. Air suspension, plenty of horsepower and torque, and a leather-trimmed cabin with the latest of Audi’s technology.
At the same time, though, it’s a potent alternative to sports sedans from BMW and Mercedes. Gone is the V8 of the old car, replaced by a 2.9-liter TFSI V6 biturbo engine. It packs 444 hp and 443 lb-ft of torque; 0-60 mph arrives in 4.4 seconds.
Outside, it’s arguably more subtle than its German rivals. That could come in useful if you want a surreptitious getaway.
