The Volvo S90 is a luxurious sedan with a cavernous interior and excellent safety features. It is also, at the same time, a performance beast. Depending on the powertrain in your Volvo S90, it will be able to leap from 0 to 60 in as little as four-and-a-half seconds. The standard B6 mild hybrid can make the same jump in just 6.4 seconds.1
