2012 Mercedes-Benz SLS AMG Roadster Long-Term Road Test


2012 Mercedes-Benz SLS AMG Roadster: Fuel Economy Update for January

February 4, 2013

2012 Mercedes-Benz SLS AMG Roadster

This was our first full month in the Mercedes-Benz SLS AMG Roadster. We are getting more comfortable with it, but to be honest, you never get really comfortable driving a nearly $250,000 car.

That's the tradeoff that comes with a car that is otherwise the highlight of most people's day. Whether it's people seeing it drive by on the street, or passengers who bug us for a ride, the SLS is everything a supercar is supposed to be.

That, of course, includes its mileage figures, which are predictably poor. This is a big car, but it's not that big. We've had Suburbans that turned in better than 13.4 miles per gallon. It's still early, though, so as the miles pile up the SLS may bump its overall average up considerably. Not that it matters.
