Bodywork

A stress-bearing steel monocoque with both the external panels and box-section superstructure are galvanised-coated on both sides, two-door Spyder, two-seater, longitudinal front engine, rear wheel drive.

Chassis

Chassis made from high resistance galvanised steel with a rear tubular sub-chassis to support the suspension and gearbox, and a front tubular sub-chassis to support the suspension and engine.

Suspension

Front: double wishbones with arms and hubs in forged aluminium; continuously variable aluminium gas dampers with adaptive damping and acceleration sensors on each wheel (Skyhook system), co-axial coils and springs.

Rear: double wishbones with arms and hubs in forged aluminium, additional radius arm to control toe-in; continuously variable aluminium gas dampers with adaptive damping and acceleration sensors on each wheel (Skyhook system), co-axial coils and springs.

19” Trofeo-design alloy wheels; front 8J x 19, rear 9.5J x 19; Tyres, front 235/35 ZR19, rear 265/30 ZR19

Brakes

Brembo braking system with four cross-drilled ventilating discs. Front 330 mm x 32 mm, rear 310 mm x 28 mm; Alloy four-pot callipers with differentiated diameter: front 46- 38 mm with ceramic insulating seals; rear 34-30 mm. Brake pads: Ferodo HP1000

Bosch 5.7 four-channel anti-lock braking system. Electronically controlled braking corrector (EBD).

Transmission

Transaxle architecture with longitudinal Maserati gearbox rigidly connected to the engine. Mechanical six-speed Cambiocorsa transmission with electro-hydraulic operation and electronic management operated by paddles behind the steering wheel, triple cone synchronisers 1st and 2nd, and double cone on 3rd, 4th, 5th and 6th. Gear shift ratios: 1st 3.286; 2nd 2.158; 3rd1.609; 4th 1.269; 5th 1.034; 6th 0.816; Reverse 2.733.

Asymmetrical limited-slip differential (25% under acceleration, 45% on lift-off), hypoid bevel gear pair, final
drive 3.73 (11/41).

Dry twin-plate clutch, diameter 215 mm (8.46 in) with flexible couplings and hydraulic control. Steel 20 mm driveshaft flexibly supported on four bearings in an engine-gearbox connection pipe.

Maserati Stability Programme (MSP) stability control with Bosch ASR, MSR and ABS.

Engine

90° V8, crankcase and cylinder heads in hardened aluminium silicon alloy. Crankshaft in refined forged steel, balanced individually on five main bearings.
