Top 5 most powerful sedans

HSV GTS-R W1

Power: 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.

6

Bentley Flying Spur W12

Power: 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.

6

Mercedes-AMG S65

Power: 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.

6

Rolls-Royce Ghost Black Badge

Power: 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.

6

BMW 760Li xDRIVE

Power: 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.
