Holden Special Vehicles announced today production volume and pricing of the W427 Commondore sedan which originally appeared at the Melbourne Motor Show this past February. With only 427 units to be produced, each of Holden's 64 dealers in Australian and New Zealand will be allocated one unit assuming they have an order. The remaining units will then be allocated to dealers based on 2007 sales figures. HSV’s owner and founder Tom Walkinshaw confirmed the price of the W427 will be $150,000 AUD as well as final power output of 375kW (502hp) and 640NM (472 ft/lbs) of torque coming from the 7.0-liter LS7 V8 from the Z06 Corvette. The Holden Special Vehicles W427 goes on sale in August.
