INNOVATIVE FROM EVERY POINT OF VIEW
The exhaust system connected to the V8 power unit uses metal catalysers rather than those made of ceramic material,
just like on racing engines. Driving a Maserati GranTurismo, the customer is behind the wheel of a car that meets the most
stringent anti-pollution laws, without having to compromise in terms of performance.
The new load-bearing body design boasts a mix of materials and technologies for weight optimisation and strength.
The central structural part is made of steel, the bonnet and front reinforcement member of aluminium, and the boot
is constructed using Sheet Moulding Compound (SMC) technology.
This keeps the component weight down and is more resistant to minor damage and corrosion. Its versatility also allowed
the designer more scope to apply his creative flair.
The GranTurismo's extremely rigid bodyshell, in conjunction with its sophisticated suspension system, enhances the car's
dynamic handling, whilst also reducing vibration. This optimises on-board comfort whatever the road surface.
The frame, constructed in high-strength steel box sections, incorporates a tubular structure in the rear to support the
suspension and differential, and in the front to support the suspension and engine.
This layout achieves the traditional Maserati rear biased weight distribution (49% front - 51% rear) with a slightly higher load
on the rear axle.
This makes the Maserati GranTurismo enjoyable to drive, responsive to commands, and enhances its safety. Moving the
engine back behind the front axle generates a large number of dynamic benefits. In everyday use, it translates into balanced
and predictable performance which makes driving very easy.
The main benefits are:
• Maximisation of traction when accelerating
• Optimisation of traction when accelerating on low grip surfaces
• Outstanding roadholding (lateral acceleration up to 1g)
• Exceptionally stable and balanced performance during emergency manoeuvres.
