Due in 2018, the controversial new Commodore will for the first time drive the front wheels and not be offered with a V8 engine option or a sedan body style.
The reduced length hasn't negatively impacted interior space because of improved packaging as a result of having the engine run across the engine bay (in an east-west configuration) rather than along the length of the car, as with every other Commodore. So the distance between front and rear occupants is just 1mm shorter than the outgoing car and rear knee room is claimed to be identical.
But the narrower cabin means the Commodore is no longer as well suited to three adults across the rear, long a sales pitch of the big-car-for-a-big-country.
And while front headroom is unchanged, rear headroom has shrunk 13mm, although Holden still claims it's more than adequate for tall Australians.
The traditional Commodore sedan will be killed off, too, instead replaced with a five-door hatchback body style to be marketed as Sportback.
There will also be a wagon, or Sportwagon, which is expected to spawn a Subaru Outback-style light duty off-roader.
Under the bonnet is the choice of two 2.0-litre turbocharged four-cylinder engines – one petrol and one diesel – as well as a 3.6-litre V6.
