Visually, this i4 aims to offer a more sporting take on what a mid-sized EV should be. The dimensions, 4,785mm long, 1,852mm wide and 1,448mm tall, are similar to those of the brand's 3 Series saloon, but there's also a 'Gran Coupe'-style GT look that gives this car a more upmarket demeanour. Unlike the larger iX, there's no EV-specific platform. Instead, under the skin, the i4 uses basically the same CLA modular cluster architecture that features in all of the brand's other mid and large-sized models, though with a super-slim lithium ion battery inserted beneath the floor of the passenger cell. The sleek shape has a drag coefficient of just 0.24Cd, helped by active elements like 10-stage adjustable flaps in the front kidney grille that open and close to aid aerodynamic efficiency.
Inside, there's a completely new approach to the company's iDrive cabin screen design. This sees a 12.3-inch digital instrument panel paired to 14.9-inch central infotainment screen, creating what the brand calls a 'Curved Display'. This is held in place by a supporting structure concealed from the occupants' view, so it appears to be standing freely in the cockpit. And the use of anti-reflective glass makes it possible to dispense with the binnacle usually required to shield the readouts from sunlight. Rear seat space is more 5 Series than 3 Series-like. And there's a big 470-litre boot.
