At 129cm high, the Mission e sits shoulder-to-shoulder with a 911, while at 199cm wide it’s a full 18cm broader. Nose-to-tail it slots neatly between the Panamera and 911, but Mauer is quick to point out the Mission e is more of a four-door 911 than a small Panamera. Given its shrink-wrapped bodywork and 911-shaped glasshouse we’re inclined to agree. So the windows, roofline and chunky arches are classic Porsche, but there are fresh, forward-thinking elements in there, too.
