The Rolls-Royce Dawn has been spied undergoing testing, ahead of its official unveiling at the Frankfurt Motor Show.

Essentially a convertible version of the Wraith, the Dawn has familiar design but adopts a retractable soft top and a modified rear end which is more conservative than the coupe.

Power will be provided by a twin-turbo 6.6-liter V12 engine that produces 632 PS (624 bhp / 465 kW) and 800 Nm (590 lb-ft) of torque. It enables the Wraith to accelerate from 0-100 km/h in 4.6 seconds, so expect the Dawn to be slightly slower.
