HSV has revealed a more powerful GEN-F line-up for 2015.

Following confirmation that it is building the world's most powerful ute, the GTS Maloo, Holden's performance tuner has announced some significant running changes to its regular fleet of models, including a bump in outputs on certain models, modest styling tweaks and new personalisation options.

The updates have coincided with small price increases on some models.

Available from late November, all R8 models (Clubsport R8, Clubsport R8 Tourer and Maloo R8) will absorb the previously optional $4995 SV Enhanced pack, increasing their power outputs 15kW and 20Nm to 340kW and 570Nm overall. The pack comprises a bi-modal air intake, high flow inlet tube, high-flow bi-modal exhaust with high-flow headers and catalytic converters and dual-mass flywheel.

In addition, the regular Maloo and ClubSport models have been fettled for an additional 8kW or power, thanks to the fitment of a hi-flow exhaust system with X-pipe intermediate and a bi-modal muffler. The changes take total outputs to 325kW and an unchanged 550Nm – the same power outputs found on the previous generation E Series 3 GTS.

Topping the 2015 range will be the GTS sedan which, along with the GTS Maloo, offers unchanged outputs of 430kW and 740Nm from its 6.2-litre supercharged V8.

As with Holden's 2015 SS-V Redline Commodore, automatic variants across the HSV range will now receive paddle shifters as standard. The six-speed automatic now brings a $2500 premium over the standard six-speed manual, $300 more than before.

HSV has also deleted manual versions of the R8 Tourer for 2015, following a similar move from Holden with its SS wagon.

Some minor styling changes have been introduced across the GEN-F range for 2015. The GTS gets a new Dark Stainless finish on its 20-inch forged alloy wheels, while R8 models will be offered with a new Tornado Grey hue on their 20-inch alloys.

In addition, HSV has introduced a new high-mounted Hyperflow performance rear spoiler for ClubSport, ClubSport R8 and GTS models (a $690 option, free on GTS), while a 'Pitch Black Style' option will be available on the three R8 options. The latter kit features "black accenting on the fender vents and mirror scalps together with the lo-line spoiler (ClubSport R8) and the tailgate applique' (ClubSport R8 Tourer)". Production of the MY15 HSV models will commence in early November, with the first vehicles available from later in the year.
