With 577 horsepower and 516 pound-feet of torque from the twin-turbocharged 4.0-liter V8, it’s quite easy to reach extralegal speeds in the R Roadster – and quickly, too. Sixty miles per hour comes in just 3.5 seconds, and hypothetically, if you keep it floored you’ll hit 197 mph. The AMG V8 sounds superb and offers some real punch starting from way down low in the revs, thanks to nearly twenty pounds of beautiful German boost in the turbos. Even with all that charm and all that power, it’s not the speed that gets us.
The R Roadster is a real charmer even around town. AMG tuned the steering to near perfection, filled to the brim with feedback and responsiveness. Helping the long roadster corner with even more vigor is the active rear-wheel steering system. Pitch the car into a corner with all you’ve got and it responds with phenomenal grip and genuine agility. Although the ride quality suffers (read below) the chassis is rock solid, with almost zero flex, even compared to the hardtop. All things considered, this car is an absolute supercar riot, even when you’re not on the track.
