Holden’s in-house tuner HSV recently took the wraps off a new super-sedan concept destined for production later in the year. The new concept was the HSV W427, a VE Commodore powered by the Corvette ZO6’s 7.0L LS7 V8 engine, and it was showcased last month at the Melbourne Motor Show.

According to latest reports, the production version of the W427 is headed to the UK where it will be sold as a flagship version of Vauxhall’s VXR8. The new car will be priced at about £55,000 ($110,000) when it goes on sale in September and will output more than 570hp and 640Nm of torque, reports AutoExpress.

With these numbers the car will be able to sprint from 0-60mph in just 4.5 seconds and easily reach an electronically controlled top speed of 155mph. This puts it in BMW M5 and Audi RS6 territory, the exact segment Vauxhall is targeting for the new model.

A company spokesman revealed the car is in the early stages of development and that it will feature a number of components developed from the racing version.

Performance features of the concept include a carbon fiber rear spoiler, six-piston brakes, 20in wheels, a custom induction system and an uprated limited-slip differential, clutch and Tremec TR6060 six-speed manual gearbox. The car also features Magnetic Ride Suspension but it’s unclear what specifications the UK model will have.

HSV. You know what it stands for. Not just Holden Special Vehicles, but what it truly stands for, the stance behind the badge. Bravado is one. Value for money is another. Most importantly, it’s muscle. True Australian outback beef squeezed into a box on four wheels. In keeping with this macho image, HSV has finally put out the MY2008 W427 into dealerships, a lesson in what engineering steroids can do to a sweet, Ausie rules-loving bloke.

With that said, we can now cut through the grass and hit some serious manure. The W427 features 7.0-litres of muscle broth sourced from US sister brand Corvette, which allows for power to escape through the rear wheels in doses of 375kW at a time, depending on the engine speed of course. The limited slip diff ensures very little smoke is added to the show during enthusiastic (what other kind is there?) takeoff, from one green traffic light to the next. The high-strength 6-speed manual gearbox plays the starring role in all this, planting maximum torque of 640Nm.

Manic as it sounds, the W427 – of which only 427 will be made – is a serious dad’s car, funked up with all kinds of comfort sweet things to make the missus smile while scaring the kids at the back all the way to the village of Tyre Shred. A 6-CD/ MP3 player is in there, so is an overhead DVD unit for them little ones to help stop them shaking in their little boots. Bluetooth is optional, as is satellite navigation. The list is long and impressive. If you are lucky enough to live close to Australia and aren’t owning one of the 90 cars already allocated for 2008 at AD155,500 then get right on it. We expect quick sales.

With these numbers the car will be able to sprint from 0-60mph in just 4.5 seconds...
