Mercedes is a conversion. Why does nobody mention that the rear passengers have their legs higher—unnaturally, or that the interior is super cramped because there's a central tunnel from the combustion model? Or slow charging?

Much cheaper and, as the twin, completely sufficient compared with the Ultra. The cockpit is a bit of an acquired taste.

Very disappointing overall for a car that comes to €57,500 with options.
After 27,000 km in it over 2 years — so many disappointments...
Despite Volvo’s updates, many “small” problems that ruin daily life:

Mirrors that desynchronize and reset when you open the car.
With the keyless option the car sometimes unlocks when you’re at a distance but won’t open when you try the door.
Intrusive driver aids that become dangerous: they slam the brakes when detecting phantom vehicles while reversing (with a wall behind) or detect vehicles in the lane to our left as a “vehicle coming from the left” (same in roundabouts).
Same issue when overtaking: it lets you pass without problem but then abruptly pushes you back into oncoming traffic when you cross the line to move over.
Screen that stays black or frozen for several tens of seconds at startup.
Performance drops sharply once battery falls below 60%.

Handling is rather mixed: very good when it was new, after two years it develops body roll, tends to overreact in corners (it bounces), and loses grip at the front in roundabouts (for a rear-wheel-drive…).

The engine is overall pleasant and powerful, but the chassis does not at all match the 272 hp.

Volvo EX30 twin performance is een super handige compacte auto die vast op de weg ligt . Is pijlsnel en je zit iets hoger. Interieur went snel . Ik heb er zelf eentje en ben er verliefd op . Heb BMW G30 gehad . Fantastische auto , maar groot en onhandig . Geef mij maar de Volvo en we zijn maar met 2 .

...the best electric car we've driven so far. Trouble-free, safe, tidy and easy to use.

The German predecessors (the Wolfsburg group) can be completely forgotten!
