TOP 5 Most powerful sedans

HSV SV GTS-R W1

474kw Old school supercharged V8 pulls off towering figures and big noise working with a four-lobe supercharger within a 6600rpm rev limit. By sheer weight of numbers alone, it’ll go down as a great.

BENTLEY FLYING SPUR W12

467kw Unique W12 engine configuration is paired with two turbos to deliver torrential torque and effortless charm, although near 2.5-tonne kerb weight dulls the big sedan’s initial acceleration.

MERCEDESAMG S65

463kw If in doubt, add more cylinders seems to have been the mantra with Merc’s flagship S-class. Its 463kw only just outpunches the S63 AMG, but with four more pots and fatter torque.

ROLLSROYCE GHOST BLACK

450kw Recently tweaked as part of the Black series aimed at younger buyers, you can thank BMW for the effortless urge of the 6.6-litre twin-turbo V12 beneath the imposing bonnet of the imperiously rapid Ghost.

BMW 760Li XDRIVE

448kw The Bee Em flagship’s 6.6-litre V12 is the same as that in the Roller (inexplicably with two less kilowatts). Set to hit our shores soon, the AWD 760 hits 0-100km/ h in 3.7sec.
