The super-hot CTS-V is the king of the Cadillac hill — and claimed to be the world's fastest four-door sedan.
Still, the key is the engine: a supercharged 6.2-litre V8 with either a six-speed manual or six-speed automatic directing power to the rear wheels. The bottom line is 410kW and 745Nm.
Unfortunately, all that engineering has left little room for a right-hand drive conversion that would bring it to Australia.
“When we put the 6.2-litre V8 engine in and the supercharger plumbing on it, we ran out of real estate,” General Motors product boss Bob Lutz says.
Its mechanical package includes magnetic ride control for the suspension, Brembo six-piston disc brakes and Michelin Pilot Sport 2 tyres.
But Lutz, always the optimist, believes there is potential for Holden Special Vehicles to tweak a go-faster CTS for Australia.
“Talk to HSV. I'm sure they will whomp up something,” he says.
Pick up the phone, HSV.
