Nissan's new flagship sedan is built upon an all-new front-drive "D platform" that is shorter between the wheels and overall, yet boasts a wider front and rear track. Why then does it look larger and meaner? Because of a butched-up styling language that Nissan calls "liquid motion." Just look at the aggressive stance and wide, upright grillework. Then note the broadly spaced, asymmetric head and taillamps and sculpted muscular lines down the sides and hood. No slab-sided antiseptic styling here; the 2009 Maxima channels the GT-R and Infiniti G35 to great effect.
