Numbers are Impressive
Earning 19 MPG in the city and 26 MPG on the highway, the Mercedes trumps V8 alternatives to almost all luxury SUV competitors. The BMW X5, Lexus LX570 and even the V6 equipped Acura MDX all feature worse fuel economy ratings than the diesel-equipped Mercedes. The only cars that can keep up are other diesels like the Audi Q7 TDI or the BMW X5 xDrive35d diesel, which doesn’t even have a third row.
That benefit at the pump doesn’t come at much of a compromise either. Making 240 hp and 455 lb-ft of torque, the GL350 is still a primo performer off the line. On the highway the truck takes just a moment to get primed for a pass, as the seven-speed gearbox chooses the perfect ratio for maximum acceleration.
As expected, the torquey diesel motor can tow and like the rest of the GL lineup is rated at 7,500 lbs.
