The GL550 is the in-your-face luxury SUV that the GL450 should have been all along. Its big grille fronts a powerful V-8 that it uses to turn massive wheels.
The ML- and GL-class SUVs get a new V-8 for 2008. Displacement goes from 5.0 liters to 5.5. AMG body styling comes along for the ride.
GL-class is expanded this year with the addition of the GL550.
