The Maserati GranSport’s normally aspirated 4,244 cm3 V8 has all the structure of the most advanced racing engines with dry sump lubrication and twin overhead camshafts per cylinder bank with four valves per cylinder hydraulic tappets. The intake cams also feature variable phase timing.
Its maximum power delivery has been upped from the original 390 hp to 400 hp too, thanks to special development work to reduce internal attrition and careful work on the intake manifolds and valve seats. The engine has been combined with a sports exhaust system that is instantly recognisable, thanks to the unusual design of its twin chrome exhausts and was designed to give enthusiasts that instantly recognisable deep, full-bodied rumble. Thanks to an electronically controlled pneumatic valve system, even more can be made of the exhaust by pressing the “Sport“ button on the central console too.
The Maserati GranSport is available only with the six-speed electro-hydraulic transmission in which the gears are changed using paddles mounted behind the steering wheel, a feature that further enhances the car’s sporty personality. The Cambiocorsa systems allows drivers to choose between various gear shifting modes (Normal, Sport, Automatic and Low Grip), and in the case of the Maserati GranSport , is controlled by specific software. Even with respect to already very highly developed Coupé Cambiocorsa system, the Sport mode in the GranSport offers 35% faster gear changing on average and also boasts automatic heeling and toeing to make dropping down a gear even faster. Thanks to the new Cambiocorsa software, the Maserati GranSport can sprint a whole kilometre from standstill in a breathtaking 23 seconds flat.
The gear shift ratios are specific too, with the adoption of a sixth gear that is 5% longer, which, in combination with its more powerful engine and improved aerodynamics, allows the Maserati GranSport to improve on the already blistering speeds of the Coupé, delivering a dizzying top speed of 180 mph.
