635 Horsepower 2017 Holden HSV GTSR, W1, Maloo

To mark the end of the Commodore VF Series II-based Gen-F2, HSV is glad to present the GTSR W1. The swan song of HSV may be labeled a “road-legal racecar,” but the truth of the matter is that this is a four-door Corvette ZR1.

The belly of the beast is an LS9 V8 that was previously used by the ZR1 between 2009 and 2013, as well as the Equus Bass 770. Based on the LS3, the LS9 V8 is a 6.2-liter engine enhanced by an Eaton four-lobe supercharger. With 474 kW (636 hp) at 6,500 rpm and 815 Nm (601 lb-ft) from 3,900 rpm, the GTSR W1 is almost as powerful as the sixth-gen Corvette in ZR1 guise.

Only available with a Tremec TR-6060 six-speed manual transmission, the rear-wheel-drive four-door sedan from the Land Down Under can accelerate to 100 kilometers per hour (62 mph) in 4.2 seconds. The 1/4-mile, meanwhile, is doable in 12.1 seconds or thereabout. Straight line performance, however, isn’t this bruiser’s strongest point. What is, in fact, is handling prowess.

 

 

Fixed-rate suspension from SupaShock, Pirelli P Zero Trofeo R rubber (265/35 up front, 295/30 at the rear), 6-piston calipers and 2-piece discs, and torque vectoring are just a few of the goodies that make the GTSR W1 the most hardcore HSV ever. The price reflects its status as well: AUD 169,990.

Converted to U.S. dollars, that sum translates to $129,150 at current exchange rates, which is ridiculous money when you think about it. The C6 Corvette ZR1, for example, originally retailed for $103,300. Adjusted for inflation ($115,155), the Corvette ZR1 is still cheaper than the GTSR W1.
