HSV Gen-F fact files

The HSV Gen-F project took 33 months from start to finish. As Holden began to finalise the VF Commodore in December 2009, HSV got into full swing once it was signed off by August 2010.

By December 2010 HSV had done the initial computer simulation testing on how an LSA engine would fit in the engine bay of a Commodore and what components would need to be strengthened.

The development of the Gen-F was the first time HSV had run to a General Motors timetable. In HSV's words, "we made the same decisions we used to make, but we made them earlier".

The new HSV range was tested in extreme hot and cold conditions, for durability testing and stability control settings, including Sweden, North America, Spain and outback Australia.

HSV tested Bridgestone and Continental tyres back to back during most of the VF development process. The company was reluctant to sever its loyalty to and its long ties with the Japanese tyre company. But test after test the Continental tyres delivered more grip, quicker lap times and performed better in all criteria.

The dial to adjust the driver settings in the GTS is from the Corvette, but with unique lettering for use in the HSV.

The water pump used on the engine is from the Holden Volt plug-in hybrid electric car.

HSV is expecting the weight and fuel consumption of most models to come down, but is yet to finalise figures. The GTS will likely be the same weight as before (or even a little heavier) given the heavy duty hardware added.

In transport mode (between Holden and HSV) the supercharged LSA engine is limited to 1500rpm so delivery drivers and other car wranglers can't thrash it.
