The GranCabrio's 4.7-litre V8 engine is upgraded with the addition of a supercharger driven by a cogged-tooth belt. Maximum boost pressure is limited to 0.35 bar. Meanwhile a water-to-air intercooler with dedicated water circuit ensures optimal power yield and healthy engine temperatures.

The Novitec Tridente "Sport" compressor conversion also includes a custom intake manifold and larger injectors. Reprogrammed engine electronics coordinate the interaction of the new high-performance components. The new mapping programme also aims to ensure an optimal power yield, durability and compliance with current exhaust emission standards.

The engine conversion costs 19,900 euros and can also be used in conjunction with a new Novitec Tridente sports exhaust system. The fully stainless-steel system features four slanted tailpipes with diameters of 90 millimeters and is available with or without a control flap. The former allows the driver to engage in sound tuning from the cockpit. Depending on the control flaps' positioning, the eight-cylinder engine can sound either sporty, subdued or with the aggressive nature of a racing car.

After the supercharging conversion the rated power of the four-valve engine jumps by 150 hp (110 kW) to a claimed 590 hp (434 kW) at 7,300 rpm. Simultaneously peak torque grows from 490 Nm to a claimed 572 Nm at 5,400 rpm. The uprated power plant interacts with the standard six-speed automatic transmission, both in manual and automatic mode: The sports car sprints from 0 - 100 km/h in a claimed 4.5 seconds while top speed increases from the standard 283 km/h to a claimed 301 km/h.

These higher speeds place greater demands on the aerodynamic properties of the vehicle so the Novitec Tridente designers have developed a number of discreet new add-on components that also fit the GranTurismo coupé version. They aim to further emphasise the cabriolet’s sporty character as well as optimising its aerodynamic properties. All body components are made from carbon fibre with either a clear coated finish or painted in body or contrasting colour.

The small front spoiler lips are attached to both sides of the production front apron with their curving shape aiming to reduce lift on the front axle, thus further improving directional stability at high speeds. In combination with the carbon-fiber radiator grille surround the two new lip spoilers aim to give the vehicle a sportier face. The rocker panel underside trim calms the airstream along the vehicle’s sides and gives the two-seater a longer, more sleeker appearance. To create an optimal aerodynamic balance, the GranCabrio can be upgraded with the a small new rear spoiler lip and a diffuser for the standard bumper. The tuner claims they each improve the stability of the handling at high speeds while these two components also aim to add a more sporty character to the rear appearance.

The makeover continues with new wheels and tyres with a staggered combination of 21- and 22-inch alloy wheels for front and rear further emphasising the wedge-shaped design of the sports car. The three-piece wheels with five double spokes are available in any desired colour and upon request or even coated with carbon fibre. The 9Jx21 wheels at the front are fitted with Pirelli P Zero high-performance tyres sized 255/30 ZR 21 while at the rear 315/25 ZR 22 tyres on 11.5Jx22 rims provide optimal traction.
