The sportiest Rolls-Royce model ever (according to the British firm's own statements), has just become a little bit faster, thanks to the tuning minds over at Mansory, who are using the Geneva Motor Show to present their program for the Wraith coupe.

It all starts with a new ECU and a complete exhaust system that runs straight to the tail pipes, for the Wraith's 6.6-liter twin-turbo'd V12.

After these upgrades, power goes up from 624hp (633PS) and 800Nm (590 lb-ft) to 730hp (740PS) at 5,500rpm and 1,000Nm (737lb-ft) delivered from 1,500 to 5,500 rpm, while the 0-100km/h (62mph) acceleration time goes down from 4.6 seconds to 4.4 seconds, and the top speed goes up from a restricted 250km/h (155mph) to 300km/h (186mph).

The display model in Geneva showcases a bespoke two-tone, chrome and petrol blue exterior paint job, along with new front and rear bumpers, integrated LED and daytime running lights, modified front fenders, side skirts, rear apron, boot and roof spoilers, and 22-inch rims in high-performance rubber from Verdestein (size 265/35).

Mansory also customized the Wraith's interior with two-tone leather upholstery and decorative trim accents in carbon fiber with a multi-coat piano lacquer.

Could be launched next summer

The 2015 Rolls-Royce Wraith Drophead Coupe has been spied for the first time.

Designed to slot below the Phantom Drophead Coupe, the Wraith convertible has a familiar design but eschews the stylish roof for a power folding soft top. Additional changes are limited but the rear end has been redesigned to accommodate the folding roof.

Power will be provided by a twin-turbo 6.6-liter V12 engine that develops 632 PS (465 kW) and 800 Nm (590 lb-ft) of torque. This enables the coupe to accelerate 0-100 km/h in 4.6 seconds, so expect the convertible to be a few ticks slower.

While the model looks virtually production ready, speculation suggests the Wraith Drophead Coupe won't be launched until next summer.
