Platform sharing within the wider Stellantis group (this car’s close relative: Peugeot 308) means a change to the model’s proportions, but it’s one that appears to have paid off. The new Sports Tourer is 60mm shorter than the outgoing model, but sits on a wheelbase 70mm longer, allowing Vauxhall to claim it as another example of efficient packaging, though without actually saying it’s as roomy inside as the old one.
With a wheelbase 57mm longer than that of the new Astra hatchback, the Sports Tourer shouldn’t be compromised in the practicality stakes, despite the squeezed dimensions, thanks to an “Intelli-Space” moveable boot floor. It can be adjusted to high or low positions to maximise room, and includes stowage for the retractable load cover. The result is a flat-floored load space with the 40-20-40 split rear backrests folded down of 1,634 litres – the old model had 1,630. With rear seats in place you have a 608 litre boot – or 548 litres if you opt for the plug-in hybrid which has its lithium-ion batteries under the boot floor.
