Although Volkswagen has yet to officially reveal the ID 4, it has previously been seen undisguised. The images were contained in filings to China's Ministry of Industry and Information Technology (MIIT) as part of documents that all firms must submit to gain type approval for new models in China.

The images show how the ID 4 will look in its production bodywork and confirm that, as expected, it will share similar design features and traits with the ID 3. The documents also confirm that the SUV will be 4592mm long, 1852mm wide and 1629mm high, with a wheelbase of 2765mm. Initially, the Chinese model will feature the 201bhp powertrain.

The ID 4 was due to be launched at this year's New York motor show, but after that show was postponed due to the pandemic, it's expected to take place in the next few months.

The ID 4 will initially be sold with a single electric motor and rear-wheel drive, with a more powerful twin-motor four-wheel drive layout set to be offered within the first 12 months of sales, according to Brandstätter.

As suggested by the ID Crozz concept, the rear-wheel-drive model is expected to offer up to 201bhp and 229lb ft of torque from its rear-mounted electric motor. The four-wheel-drive model will add a front-mounted motor with an additional 101bhp and 103lb ft, taking its overall output to 302bhp and 332lb ft.

The ID 4 will offered with a range of different battery options, the largest of which, a rumoured 83kWh unit, will offer a range of up to 311 miles on the WLTP test cycle.

It will also offer rapid-charging capability that will allow its battery to be charged to an 80% state of charge within 30min on a 125-150kW system.

There will be two versions of the ID 4: a standard model and a coupé-SUV in the vein of the original concept, expected to be named the ID 5. This will be revealed at a later date.

"As early as 2020, we aim to sell 100,000 all-electric Volkswagens [per year]," said Volkswagen Group chairman Herbert Diess at the Crozz concept's 2017 unveiling. "But this is just the beginning. By 2025, annual sales could increase tenfold to one million vehicles."

The ID 4 and ID 5 aim to combine the dynamic lines of a modern-day sports car with the all-terrain capability of a dedicated off-roader. They're said to offer interior space on a par with the Tiguan Allspace, a long-wheelbase version of Volkswagen's best-selling SUV model.

The ID Crozz concept is 4625mm long, 1891mm wide and 1609mm tall, putting it in between the five-seat Tiguan and seven-seat Tiguan Allspace in terms of dimensions. The wheelbase is 2773mm.

The MEB-based ID Crozz features two electric motors – one mounted within the front axle, and one at the rear - powered by an 83kWh lithium ion battery housed within the floor structure. The front electric motor sends its 101bhp and 103lb ft to the front wheels. The rear unit delivers 201bhp and 228lb ft to the rear wheels, giving the car a combined output of 302bhp and 332lb ft of torque.
