The interior layout, fit and finish
Inside, the Vauxhall Corsa-e looks very different to the Peugeot e-208 despite the two cars being closely related. The Corsa-e's layout is far more conventional and conservative, although that does actually bring some benefits.
For example, you're unlikely to have any issues viewing the instrument dials behind the steering wheel. In the e-208, the instruments are mounted above the wheel, which doesn't suit everyone. Plus, the Corsa-e has proper dials and buttons to control its air-conditioning, while in the e-208 you have to faff around with the touchscreen to adjust the interior temperature.
