Walkinshaw Performance has introduced their tuning packages for the Holden VF Commodore and HSV Gen-F. The name of the projects are W457 and W497.

"The W Series has already seen the naturally aspirated W310 and W375 packages which offer terrific performance and value for money that we have developed thanks to the outstanding base vehicles- the VF SS Commodore and the Gen-F HSV. Today we take another step with the W457 and W497 packages. These packages represent the pinnacle of Australian automotive design and engineering capabilities. On power figures alone it's impressive, but as we always say; drivability is the number one goal and we believe that these W Series twins are exceedingly well mannered in this key area. That said, it's hard to hide the performance results and these cars are guaranteed to bring a smile to the face of every motoring enthusiast.", commented WP General Manager Tony Harris.

The W457 boosts the VF Commodore's 6.0 liter V8 engine to 621 HP (457 kW) and 780 Nm (575 lb-ft), while the W497 for the HSV Gen-F's 6.2 liter V8 has 675 HP (497 kW) and 955 Nm (704 lb-ft) of torque.

The pricing starts from $18,990 AUD.
