GENEVA MOTOR SHOW: Holden 2018 Commodore Sportwagon

We've seen Holden's all-new, imported 2018 Commodore sedan, which is actually a liftback, and now General Motors has officially unveiled the wagon version.

Confirmed to continue the homegrown Commodore's 'Sportwagon' name when it arrives Down Under early next year, the German-sourced wagon will make its world debut in Opel form at the Geneva motor show next month.

Holden says its first imported Commodore wagon will offer 1640 litres of total cargo volume – accessible via a foot-operated motion sensor – which is well down on the outgoing model (2000 litres).

Like the sedan, a one-touch folding 40/20/40-split rear seatback will be optional for the Commodore for the first time.

As with the sedan (there will be no ute), Holden claims its next Commodore will deliver "class-leading driving dynamics" thanks to a "world-first" Twinster adaptive all-wheel drive system with torque vectoring.

However, as per the sedan, AWD will likely be fitted only to the top-shelf 'SS' version powered not by a V8 but a 230kW/370Nm 3.6-litre V6, with mainstream 2.0-litre four-cylinder petrol and diesel models driving their front wheels for the first time, albeit via Holdn's first nine-speed automatic transmission.

Also promised beneath the "sleek European design" is "superb refinement" and a host of new safety features including Lane Keep Assist, Autonomous Emergency Braking, IntelliLux LED matrix lights, adaptive cruise control.

Head-up display and rear cross-traffic alert continue, alongside forward collision warning, lane departure warning and blind-spot monitoring.

Billed as the most advanced Commodore ever, the 2018 model will bring other advances such as adaptive three-mode ‘Flexride’ suspension and weight savings of around 200kg thanks to a new E2 platform, which will lower fuel consumption.

Further boosting efficiency will be Active Fuel Management cylinder shutdown and idle-stop systems.

New (and likely optional) features will include massaging and ventilated front seats, heated front and rear seats, new-generation head-up display and an 8.0-inch infotainment display with Apple CarPlay and Android Auto compatibility.

As expected, the wagon features the same Opel Monza concept car-inspired frontal design as Opel's new Insignia, on which it will be based, as well as LED tail-lights and silver roof-rails.
