HOLDEN Special Vehicles has finally bitten the bullet and put a 7.0-litre Chevrolet V8 in one of its Commodore-based cars. Holden's performance arm had built a racer-for-the-road Monaro with a similar 7.0-litre engine as a concept back in 2002 and even started taking cash deposits for the car it called the HRT 427. Unfortunately, the business case didn’t make sense and HSV pulled the pin on the mighty coupe. Its second attempt, the W427, is not a road racer, but a luxury sedan with a race-bred Chevrolet engine. HSV upgraded the W427 with a new manual transmission, improved brakes, unique interior trim and details, special wheels and unique styling. It doesn’t come cheap, with the W427 attracting a sticker price of $155,500.
