About the HSV GTS R W557

The 2017 HSV GTSR W557 represents the pinnacle of aftermarket-enhanced Australian muscle, born from a collaboration where Walkinshaw Performance took the already potent supercharged 6.2-litre LSA engine and pushed its output to a staggering 557 kW. This comprehensive upgrade package transformed the standard GTSR into a literal powerhouse, featuring a high-lift camshaft, high-flow injectors, and a unique supercharger pulley set that delivered an incredible 930 Nm of torque. In the current Australian market, the W557 occupies a prestigious niche, appealing to a buyer pool that demands even more raw performance than the factory-standard flagship. Desirability is exceptionally high for manual sedans that retain their official Walkinshaw certification and signature ceramic-coated headers, particularly those finished in hero shades like "Light My Fire" or "Spitfire Green." Because these modifications were applied to the final run of locally manufactured HSVs, the W557 has cemented its status as a blue-chip investment, maintaining a significant market value premium for those seeking the ultimate evolution of the Zeta platform.
