Holden Special Vehicles Reveals Commodore W427 with +496Hp LS7 V8

The muscle-car party in Australia just keeps going on and on; HSV or Holden Special Vehicles, unwrapped the LS7 V8 powered W427 Commodore at the Melbourne Motor Show. While power output figures are still to be confirmed, the W427’s 7.0-liter or 427 c.i. V8 engine is likely to produce in excess of 496 Hp and 640 Nm or 472 lb/ft of torque.
HSV Managing Director, Scott Grant, said: “The W427 will be quite possibly the fastest road registrable Supercar ever produced in Australia and among the quickest anywhere around the world. The W427 will only be produced in limited numbers and we want to reflect that exclusivity in how we connect with our Supercar customers”.
Styling and design highlights of the W427 include an all new front fascia, a three piece carbon fibre rear spoiler, 20 inch machined faced alloy wheel, unique exhaust tips and red leather interior. The W427 is scheduled to enter production in the middle of the year and will be available for sale in dealerships in the third quarter of 2008. –Details and pics after the jump
