Those wanting a full-on, all-terrain Benz can get an off-road package with dual-range four-wheel drive, and center and rear differential locks. The standard 4.5-liter V8 rated for 335 hp and 339 lb-ft of torque. It hooks up with a seven-speed automatic transmission. Benz says zero to 60 mph takes 7.4 seconds.
Inside, the GL450 is roomy and has an upscale feel. A tall adult can get comfortable in the third row thanks to a sunken footwell design, and a standard double-sunroof configuration enhances the cabin's open feel. Both the second- and third-row seats fold flat, and the 50/50 third row has a power-fold feature. There's 43.8 cubic feet of cargo space with the third row folded, 83.3 cubic feet with the second-row seats folded.
