HSV E Series II focus on fuel

The company is not revealing too many details about the HSV E Series II upgrades but buyers can expect some visual and engine tweaks to deliver more power from the 6.2-litre V8 without sacrificing fuel economy.

Power is believed to have been lifted from 317kW to around 320kW but engine emission tweaks have delivered slight gains in fuel economy.

HSV spokesman, Simon Frost, says the company is focusing on fuel consumption but there will also be a number of significant visual improvements to the cars.

HSV managing director Phil Harding says the multi million dollar program includes "major visual differentiation and introduces at least five Australian auto firsts, a huge shot in the arm for the local industry".

"We know our customers want the latest technologies, as well as distinctive luxury and performance features in their HSV," he says.

"The new range delivers in improved economy, more power, some truly exciting driver enhancements and distinctive design themes across the board."

The new HSV line-up arrives in showrooms around September.
