The latest member of VW's growing family of I.D-badged electric concepts debuts in Shanghai, ahead of its first production model due in 2020.

Volkswagen has continued its stream of electric concept cars, adding the high-riding I.D. Roomzz to its collection in Shanghai.

Built on the same modular MEB underpinnings as the brand's previous electric concepts – the same underpinnings that'll drive Volkswagen Group as it pushes toward widespread e-mobility – the Roomzz represents the brand's vision for a practical family crossover. Or should that be crozzover?

When it launches in 2021 (at least, for the Chinese market) Volkswagen says the car will have three rows of seating and Level 4 autonomous capabilities.

Up front, the headlamps and 'grille' outline are both in keeping with previous electric Volkswagen concepts. That means lots of rounded shapes, with friendly LED detailing aplenty.

Although there are big concept wheels and skinny concept mirrors, we'd suggest the leap from concept to production won't be massive here.

There's minimal detailing along the flanks, and a tall tailgate. You'll notice the slim pillars and tall windows, both of which should make for an airier, more spacious feeling from inside and better visibility all around.

There's also a neat chrome strip running along the roofline, for an extra dash of show-car sizzle on the stand in Shanghai.

Under the skin is a pair of electric motors making 225kW, hooked up to an 82kWh battery good for 450km of range on the tougher WLTP test cycle. That's in keeping with previous I.D. concepts, and should provide a loose guide as to what Volkswagen is aiming for when the Roomzz actually reaches production.

Thanks to 150kW fast charging, an 80 per cent charge takes around 30 minutes.

Behind the wheel, the usual concept array of screens serves as a centrepiece. The driver is faced with a fully digital display, and there's a huge screen taking pride of place in the dashboard. Volkswagen says it appears to float, we'd argue it looks pretty firmly attached. Semantics.

Light-coloured materials dominate, once again helping to keep things light and airy. Just don't let your concept kids spill their concept drinks on your concept seats, okay?

With no transmission tunnel eating into space, storage spaces abound, and there should be an abundance of space for leggy teenager in the back seats.

Volkswagen has made much of the space efficiency afforded by its MEB platform – the Golf-sized 'Neo' will purportedly have the cabin space of a current Passat when it launches – and the Roomzz appears to take full advantage.

The Roomzz is on show in Shanghai.
