When I first heard about the technical solution proposed by the Koenigsegg Regera plug-in hybrid hypercar, it really peaked my interest. There’s nothing particularly special about how Koenigsegg married a twin-turbo V8 and three electric motors (it’s been done before), but what’s cool about it is the fact that it has a single drive ratio for the internal combustion engine that takes it from naught all the way to 249 mph. That’s like starting in top gear and then accelerating towards peak velocity, but what’s even cooler is that thanks to a special exhaust, it actually sounds awesome while accelerating, at any speed.
