Onyx Concept has introduced their new Rolls-Royce Ghost San Mortiz.

Described as the "ultimate expression of sporty dynamism and style," the San Mortiz features a new front bumper with a handcrafted satin-carbon spoiler.  The model also has revised side skirts, a rear spoiler and a four-tailpipe sports exhaust system.  Other notable highlights include a retuned suspension and 22-inch alloy wheels. 

Under the hood, the twin-turbo 6.6-liter V12 engine has been tuned to produce 613 bhp (457 kW) which is an increase of 50 bhp (37 kW).  The company declined to say how fast the car is but the standard model accelerates from 0-60 mph in 4.7 seconds before hitting a limited top speed of 155 mph (250 km/h).
