An appreciation of what the 3GT’s unorthodox dimensions offer in terms of increased cabin space is crucial to the car’s appeal, but anyone expecting a drastic step change from either of its 3 Series stablemates will perhaps feel short-changed by the new addition. Instead, this is a reasonably subtle embellishment of the already excellent space on offer elsewhere.
The feeling of familiarity won’t be lost on the driver, as the handsome dashboard changes not one jot. The only alteration is the ergonomic relationship; BMW has raised all of the GT’s seats by 59mm, making you an overseer of the controls rather than the embedded operator around which the saloon’s chassis pivots.
If you’re not too long of leg, the captain’s chair can be set low enough to recognise the extra headroom afforded by the loftier roofline, but the regular 3 Series is already generous here, so the advantage is negligible.
In the back, the difference is more tangible. BMW says, thanks to the higher hip point and elongated wheelbase, there’s an additional 70mm of legroom behind the front seats. Our objective tape measure and subjective knees didn’t quite concur with that, although only a mean tester would argue that the space is insufficient for a genuinely superior sense of comfort. Being further from the ground inevitably makes getting in and out that little bit easier, too.
