The Maserati Coupé is a true four-seater capable of comfortably seating two adults in the rear seats. It has a wheelbase of 2,660 mm (105 in) which is about 76 mm (3 in) longer than the rival Jaguar XK8 and 305 mm (12 in) longer than a Porsche 911 (996). Overall vehicle length is 4,523 mm (178 in), width is 1,822 mm (72 in), and height is 1,305 mm (51 in). Total curb weight is 1,670–1,680 kg (3,682–3,704 lb). The design is similar to the preceding 3200 GT but the boomerang shaped taillights were replaced in favour of more conventional units.
Both models utilize the F136 R V8 belonging to the Ferrari/Maserati F136 engine family; it displaces 4,244 cc and is rated at 390 PS (287 kW; 385 hp) at 7,000 rpm with a peak torque of 450 N⋅m (332 lb⋅ft) at 4,500 rpm.
Significant changes from the prior 3200 GT engine were the larger displacement resulting from an increased cylinder bore diameter and the move to a naturally aspirated intake system which replaced the twin-turbocharged induction approach Maserati had used for the previous 20 years, fundamentally because the powertrain was now Ferrari based. The crankshaft is of cross plane design. The engine operates at a compression ratio of 11.1:1 with the eight cylinders configured in a 90° V design. The cylinder bore diameter is 92 mm (3.62 in) and piston stroke length is 80 mm (3.15 in). The engine shares many of the design features of modern racing engines, including dry sump lubrication, a pump assembly located outside the crankcase, and four valves per cylinder. The 32-valve DOHC utilises chain-driven, twin-overhead camshafts that provide valve actuation in less than 0.15 seconds, with the intake cams being controlled by variable valve timing. The crankcase and cylinder heads are made from an aluminum and silicon alloy, giving the engine a relatively light weight of 184 kg (406 lb)
