The 2009 Maserati GranTurismo lineup expands to include a top-line S model. This four-passenger coupe shares much of its basic design with Maserati's Quattroporte sedan. The standard powertrain is a 405-hp 4.2-liter V8 and 6-speed automatic transmission with steering-column-mounted shift paddles. New for 2009 is an S model with a 440-hp 4.7-liter V8 shared with the Alfa Romeo 8C. Unlike most front-engine cars, the GranTurismo has a rear weight bias, which Maserati says improves handling. Standard safety features include ABS, traction control, antiskid system, front side airbags, and front curtain airbags. Standard on all models are dual-zone climate control, adaptive bi-xenon headlights, and a rear obstacle detection system. Also standard are a navigation system, 10-way adjustable front seats with memory that power forward to ease entry to the rear seats and a power tilt and telescopic steering column that raises and lowers for easier ingress. This evaluation is based on preview test drives.
