"Making its North American debut at the LA Auto Show, the Sport GT is the high- performance version of Maserati's Quattroporte flagship. Power is provided by a 4.2-liter, 400 horsepower V-8 mated to a Cambricorsa paddle-shift manual transmission that can change gears in 1/10th of a second. Performance figures include 0 to 60 mph in 5.2 seconds and a top speed of 170 mph. Features include Maserati's "Skyhook" continuously variable adaptive suspension, racing-style Brembo brakes, 19-inch alloy wheels and carbon-fiber interior trim."  (quote from L.A. Auto Show website)
