Mercedes-Benz redesigns its midsize SUV for 2006, giving it more power and larger dimensions, but seating for five instead of seven. ML-Class construction switches from truck-type body-on-frame to car-type unibody. Compared to the 1998-2005 version, the wheelbase is 4 inches longer, the body 6 inches longer and 3 inches wider. V6 ML350 and V8 ML500 versions return. ML350 has a 268-hp 3.5-liter replacing a 232-hp 3.7. ML500's 5.0 V8 now has 302 hp vs. 288. A 7-speed automatic replaces a 5-speed as the sole transmission. Both MLs have all-wheel drive without low-range gearing. ABS and traction/antiskid control are standard. ML350 has 17-inch wheels, ML500 18s; 19s are available for both. Front side airbags and curtain side airbags are standard. Rear side airbags are available. MLs have a 60/40 split folding rear seat. For '06, the shift lever moves from the center console to the steering column. Standard on ML500 and optional on ML350 is leather upholstery and wood and aluminum interior trim. Available for both are a navigation system, steering-linked xenon headlamps, and Mercedes' Tele Aid assistance.
