The coupe-style vehicle, following on the proportions and essence set by its 5-Series GT sibling, is 200 mm longer than the Touring 3er, has a 110 mm longer wheelbase and stands 81 mm taller.
Naturally, the interior benefits the most, improving on aspects of space and freedom of movement over the rest of the 3er range. Aside from extra headroom, both front and rear seating position is raised by 59 mm, and the rear compartment gets 70 mm of additional legroom over its sedan and touring stable mates.
As for the boot space, there’s 520 litres on call here, and that’s 25 litres more than the Touring. Key features are a large load aperture and high-opening tailgate, as well as a 40:20:40 split/folding rear seat bench and a two-piece parcel shelf.
An active rear spoiler makes its debut on the car, its job to provide both visual lightness and reduce lift at touring speeds. Wheel sizes start from 17-inches for the baseline specification.
Besides the three equipment lines (Modern, Luxury and Sport), there’s an entry-level – or baseline – version and an optional M Sport package, which becomes available from July.
Three petrol and two diesel engines will be available at point of debut, all TwinPower Turbo units. In terms of petrol variants, the 335i Gran Turismo leads the pack, with its 3.0 litre six-cylinder, followed by the 328i GT and 320i GT.
For the diesels, the 320d GT and 318d GT are the oil burners at launch. Transmission choices are a six-speed manual – as standard in Europe – and an eight-speed automatic, both linked to Auto Start-Stop. As usual, plenty of EfficientDynamics and ConnectedDrive tech on call on this one, from the earlier mentioned Auto Start-Stop right up to HUD.
