Went from diesel to gas
By helilog on


2007 Mercedes-Benz GL-Class GL450 4dr SUV AWD (4.7L 8cyl 7A)


Traded an ML320CDI diesel for a GL450 gas V-8. The diesel has a narrower power band, more gear shifting, with 3-4 second bursts of huge power on demand in the upper gears. The gas V-8 has a wide, slightly weaker power band, less gear shifting, extended acceleration leaves the diesel for dead. Pick your poison. V-8 averaging 18mpg overall on regular gas, canceling some of the diesel's excellent 25mpg on pricey diesel fuel. The GL air suspension gives a smooth, level ride. Think S-Class. Car-like steering and brakes, much better than the vague, jerky brakes on the diesel. Standard manual rear hatch is light, easy to use. Nav system data entry is tedious, results are confusing.

Best Features

The GL is a great city car with a short turning radius and excellent visibility out the big, low rear side windows for lane changes, parking and such. More goodies: All side windows open. Two sun roofs. Fit and finish, style, quality and comfort of the standard MB Tex 7 seat interior is excellent.

Worst Features

Price the nav system option at $1.99 because that is what it is worth. Perforate the sweaty optional leather seats for ventilation. Make xenon headlights standard. (Although the normal halogen lights are adequate, they just suffer compared to the xenons. It's a safety issue.)
