Opel definitely needs to make things right in its wagon lineup because the Astra Sport Tourer’s cargo capacity with the rear seats down is actually bigger than the Insignia Sports Tourer’s by a full 100 liters (1,630 vs 1,530). Both of them have the same 540-liter trunk space with the rear seats in place, but the all-new Insignia Grand Sport Tourer wagon will address this issue by providing increased hauling capabilities.

It’s going to do that by growing in size taking into account the hatchback/liftback will be elongated by 5.5 centimeters (2.1 inches), so look for something similar for its wagon counterpart. Some of the stretch is going into the wheelbase to enable superior rear legroom, but the trunk should also take advantage of the increased footprint.

To be brutally honest, the camouflaged prototype spotted here gives the impression of a hearse, but look closer and you’ll notice Opel has slapped on some extra panels affixed to the real body as a way to mask the wagon’s appearance. The roof-mounted spoiler at the back stands out right away because there’s obviously something tacked on to make it bigger than it actually is and it’s more obvious when you look at the recessed third brake light.

Some other faux panels attached to the prototype’s side profile contribute to make the wagon seem bulkier and quite unattractive. But don’t worry, as once those fake bits and the camouflage will come off, it should turn out to be a handsome wagon since the styling will have a lot in common with the rather stunning 2013 Monza concept.

The test vehicle was equipped with the standard halogen headlights, and we already know the second-gen Insignia will be available with new matrix LED headlights featuring 16 light-emitting diodes in each cluster representing twice as many as those in the Astra K.

Not only will the new Insignia wear the usual Opel and Vauxhall badges, but it will also travel to America to become the 2018 Buick Regal wagon as well as to Australia where it will be sold as the 2018 Holden Commodore. The standard hatchback is expected to be unveiled before the year’s end, prior to a confirmed public debut in March at the 2017 Geneva Motor Show. The more practical body style should arrive several months later, quite possibly in September on its home turf in Frankfurt.
