Styling aft of the C-pillar is derived from last year's Sportspace concept with wraparound LED tail-lights. The top-end GT model also boasts a Sportspace-inspired diffuser integrated into the rear bumper (photos here).
With the rear seats up, the boot can carry 553 litres worth of gear according to the VDA standard, an increase of 48L over the sedan. To help with load lugging, the rear seat split folds 40:20:40, and there's a powered tailgate that can be automatically activated when the key fob is in close proximity.
Just like the sedan, the Optima Sportswagon is 4855mm long, 1860mm wide, and rides on a 2805mm wheelbase. Height has grown by 5mm to 1470mm.
Available features include smart cruise control, autonomous emergency braking, lane keeping assistance, automatic high beam activation, blind spot monitoring, and speed limit sign recognition. Depending on the model, the Sportswagon rides on 16- to 18-inch alloy wheels.
In Europe, the Optima wagon will be offered with the choice of three four-cylinder engines: a 120kW/196Nm 2.0-litre four-cylinder petrol, a 104kW/340Nm 1.7-litre turbo-diesel, and a 180kW/353Nm 2.0-litre turbocharged direct-injection petrol motor.
The new wagon is targeted squarely at Europe, with the company claiming that two-thirds of sales in the Mondeo-class, and fully three-quarters of all fleet sales in the segment come from wagon variants.
The Optima Sportswagon goes on sale across Europe from the fourth quarter of 2016.
Kevin Hepworth, Kia Australia's general manager of media and corporate communications, has informed CarAdvice that the local arm will "certainly be having a close look at the Sportswagon, but there is quite a bit of research still needed to see how a wagon might fit into the model lineup, particularly given the seemingly ever-increasing popularity of SUVs".
