The Volkswagen ID.4 is very spacious, with more than enough room in the cabin for 4 fully grown adults. Headroom is plentiful in the front and rear, while those in the back will also get more than enough legroom. A relatively flat floor means even a 5th passenger will have just enough space for their head and legs. They’ll be a bit tight for width, though.
Further back, the ID.4 comes with a 543-litre boot. That makes it larger than that of the Audi Q4 E-Tron or the Ford Mustang Mach-E, but slightly smaller than you’d find in a Skoda Enyaq iV. It’s certainly big enough for a family’s holiday luggage, musical instruments or sports equipment, let alone shopping and school bags. It’ll be plenty for most customers.
