Mercedes Benz has some big plans for next week’s New York Auto Show, with no less than three world debuts planned, as well as the as the U.S. debuts of the 2010 model year E-Class Sedan and Coupe.

The three world debuts include the unveiling of the all-new E63 AMG performance saloon, the production version of 2007’s ML450 Hybrid concept and the 2010 model year facelift for the GL-Class SUV.

On display will be the renamed GL350 BlueTEC diesel and GL450 petrol model, both of which will feature a restyled grille, new bumpers, wheels and new lights with LED accents.

The GL350 BlueTEC replaces the current GL350 CDI BlueEFFICIENCY and is claimed to offer 20-30% better fuel economy than the comparable petrol model.

The seven-seat SUV also boasts an impressive cruising range – up to 600 miles at highway speeds.

The interior should also receive a number of trim and specification updates, including the addition of Mercedes’ Elegance and Avantgarde trim levels.
