EVERYTHING. SV8 is a new model created by Holden, positioned between S and SS Commodore variants.

As for the VY Commodore facelift, apart from the new front and rear exterior sheetmetal styling, changes for the low-series sports models include new exterior mirrors, a new plenum ramp behind the bonnet, dark-tinted tail-light lenses and a new 'floating' rear wing.

Inside there's an all-new dashboard, new steering wheel, mobile phone compatible Blaupunkt sound system to replace the dated Eurovox unit, side airbags, new cloth trims, new instruments and a multi-function information screen displaying gear selection, audio details and service indicator.

The 12-volt power outlet has been relocated to inside the centre console, road speed-sensitive variable intermittent wipers and audio volume control have been added, and there is now a stopwatch function for the trip computer.

Commodore SS also now comes standard with auto headlights on/off, twilight sentinel, front reading spotlights, rear windscreen sunshade, front seatbelt force limiters and an alloy pedal cluster.

There are also a number of powertrain updates, including the liberation of an extra 10kW and 15Nm - plus a beefier exhaust note - via Monaro-style induction tract revisions and the adoption of a full-length, stainless steel twin exhaust system.

Finally, recalibration of the front suspension damping is aimed at increasing front-end compliance and ride comfort.
