Holden HSV W427 'muscle car' revealed at Australian Motor Show to spill over 500 bhp from the 7.0-litre Corvette engine.

Holden is working on unleashing its might on Australian roads as it revealed the HSV W427 at the Melbourne Motor Show. The HSV – Holden Special Vehicles – will be the fastest standard road car to ever come out of Australia, and will probably be one of the quickest globally as well. Unconfirmed power figures put the W427 at over 370kW and 640Nm of torque. Such numbers are seen only in saloons like BMW M5 and Mercedes-Benz E63 AMG. Many thanks to Corvette’s 7.0-litre LS7 power plant.

To better utilize the power, a limited slip diff will be used in conjunction with a new high-strength 6-speed manual shifter.

The car receives GM product’s Magnetic Ride suspension which helps adapt the car to current road conditions for optimum handling. A number of exterior enhancements such as carbon fiber rear spoiler, 20-inch wheels and a new front fascia.

What a tribute Australia’s original “muscle car” which turned 20 years old today.
