The 2004 Maserati Spyder

Maserati Spyder

A top speed of 176 mph is complemented by superb acceleration figures over short distances – the result of superb response and excellent traction – and over longer distances as a result of the prodigious engine torque, power delivery and sleek aerodynamics. In addition to the 0-to-60 mph acceleration time of just 4.9 seconds, the Spyder accelerates from 0-to-400 metres in 13.3 seconds and 0-to-1000 metres in 23.9 seconds.

The integrated Bosch ME7.3.2 ignition and injection systems incorporate OBD II (On-Board Detection and Diagnostic System), which allows operating malfunctions in the engine control system to be detected, guaranteeing compliance with emissions limits. The new engine also meets current and future environmental protection standards. The accelerator is an electronic ‘drive-by-wire’, while the ECUs communicate with the other systems by CAN line (Controlled Area Network) to optimise engine management processes. Great attention also went into the layout of the engine bay, which combines external shielding with classic Maserati colours, such as the red camshaft covers.

Transmission

The Maserati Spyder GT is equipped with a longitudinal mechanical gearbox, with six forward speeds plus reverse, triple cone synchronisers on 1st and 2nd gears, and double cones on 3rd and 4th gear ratios. To achieve the best weight distribution, the gearbox is located in-unit with the rear axle and limited-slip differential. In the Cambiocorsa version, the gearbox incorporates the entire hydraulic actuation system.

There is a rigid link between the engine and transmission, the two assemblies linked by a tubular element housing the propeller shaft. This architecture enables an ideal weight distribution between the front and rear axles to be achieved, with a front-rear split of 53%-47% respectively. The car's behaviour is therefore stable and balanced, delivering maximum traction and maximum pick-up.

Cambiocorsa

Another important innovation of the transmission design is the electro-hydraulically-actuated gearbox control with computerised gear selection on the Spyder Cambiocorsa model.

The new gearbox management system brings racing technology to the Spyder driving experience, improving performance and offering the comfort and safety of an advanced automatic transmission. The Cambiocorsa does away with the clutch pedal and gear selection so that clutch engagement-disengagement is managed electronically by the control unit incorporated in the engine management system.

To ensure the best possible solution in terms of speed, ease of operation and safety under all conditions, the Cambiocorsa transmission features two paddle shifts behind the steering wheel, integral with the steering column, to change up and down. Reverse control is on a separate panel on the central tunnel.
