This is the first SUV I have owned, unless you count the Volvo XC70 I had. I am not a big fan of SUVs but they have their purpose. We wanted something that would ride more people comfortably, be able to tow a car trailer and haul stuff, and is great in the winter. We also liked the Mercedes since the operator controls are so similar to our E350. This vehicle has the 362HP twin turbo inter-cooled 4.7L V8 engine (M278). This is the lowest power rating for this engine. It is the same powertrain as the GL550 of this year that is rated at 429HP and this engine in the S-Class was rated up to 450HP. There is an aftermarket flash file that will re-rate this powertrain to 500HP/580ft-lbs. This is the first year of the X166 GL chassis which brought many evolutionary changes to the GL line. We don't intend to put that many miles a year on this as it is not our daily driver except in the winter.
