context_page_description: The Maserati Coupé and Spyder are a series of grand tourers produced by Italian automaker Maserati from 2001 to 2007. The two nameplates refer to the four-seater coupé and two-seater convertible models, respectively. The design of both models was based on the preceding 3200 GT, which was not sold in the US. Due to the confusing nature of the names "Maserati Coupé" and "Maserati Spyder" the Coupé and Spyder are both commonly referred to as the 4200 GT, which is an evolution of the prior model name and a reference to the increase in engine displacement from 3.2 L to 4.2 L.
  The Spyder was first unveiled to the public at the 2001 Frankfurt Auto Show with the Coupé's debut following shortly thereafter at the 2002 Detroit Auto Show. Sales in the United States began in March 2002 for the Spyder and in May for the Coupé. The introduction of the Spyder heralded Maserati's return to the North American market after an 11-year hiatus. Almost as soon as it was introduced, the Spyder was selected by Forbes as the Best GT for 2001.
  The Coupé and Spyder were designed by Giorgetto Giugiaro of ItalDesign, who also designed the Ghibli, mid-engined Bora, Quattroporte III and the 3200 GT as well.
context_section_description: 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 crossplane 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).
