The Corvette ZR1’s supercharged, 6.2-liter V8 engine is paired with the HSV GTSR W1. This produces 635 horsepower.
Holden Special Vehicles has introduced a trio hardcore GTSR-badged special-edition models as a last hurrah to the Zeta platform. Also, it marks the end of Australian manufacturing for the Commodore set to be retired on October 20.
The W1 is the least expensive of all the models. It comes in a limited edition of 300 units and costs $166,990 Australian dollars per pop. It also features a supercharged LS9 6.2L V8 engine taken from the Chevy Corvette ZR1. It produces 635 horsepower (474 megawatts), making it more powerful than the Mercedes AMG E63 S. The W1 also has 603 horsepower (450 kW), which is generated by a biturbo-4.0-liter V8 motor.
The massive power is channeled through the custom 20-inch forged aluminum wheels, shod with Pirelli P Zero Trofeo R rubbers exclusively through a close-ratio six speed manual gearbox. HSV has released preliminary specs that the GTSR W1 can reach speeds of 62 mph (100 km/h) in 4.2 seconds. It will also reach a electronically limited top speed of 155mph (250 km/h). The car’s maximum speed would be 182 mph (293 km/h) without a limiter.
The body is much more aggressive and features wider fenders, carbon fiber rear spoiler and a diffuser. It has received an upgrade to the interior cabin, which includes more Alcantara, body-hugging and other modifications that make it stand out amongst the GTS.
GTSR is available in sedan and Maloo ute flavors for $109,490 and $96,990. It features a supercharged LSA Generation IV V8 of 6.2-liters with (435kW) on tap, coupled via a six speed manual. HSV will offer these two models with an optional six speed automatic gearbox for an additional $2,500.
HSV has updated the brakes on all three GTSR models. They will be standard with a 6-piston AP Racing package with 410mm front rotors to cope with the extra punch. The GTSR models have the semi-active Magnetic Ride Control system. W1 is the top-of-the-line model and uses a new “SupaShock”, a suspension that Walkinshaw Racing developed for the Supercars championship.
Tim Jackson, HSV’s managing director, spoke out about the long-awaited return of the GTSR badge.
“We are confident that we have delivered the best product and most powerful cars this country has ever seen.”
