The Maserati GranTurismo is a two-door, four-seat coupé produced by the Italian car manufacturer Maserati. It shares the platform of the Maserati Quattroporte V and parts of the Ferrari 599 GTB and Scaglietti.
The chassis is made of stamped and boxed steel sections, and is complemented by two aluminium subframes: one at the front supporting the engine and providing suspension attaching points, and a tubular one at the rear supporting both suspension and differential (or the entire transmission in transaxle cars). Structural body panels are steel, the engine bonnet is aluminium and the boot lid is a single sheet moulding compound piece. The base GranTurismo 4.2 has a drag coefficient of Cd=0.33.
The suspension system consists of unequal length control arms with forged aluminium arms and cast aluminium uprights, coil springs and anti-roll bars on both axles. Dampers are either fixed-rate and set up for handling or “Skyhook” adaptive. The Skyhook system uses aluminium-bodied gas dampers, allowing automatic and continuous damping rate adjustment by means of proportioning valves.
