The silhouette suggests mini-MPV, and this is fully reflected inside with upright seating for five at a pinch. The contemporary looks continue within the styling of the steering wheel, dashboard and high-resolution displays.
You step up into the cabin, which boasts a flat floor, underneath which sits a 230kg battery. The lithium-ion unit consists of 96 individual cells and comes with a warranty valid for up to six years or 100,000 miles. There is a commanding view from the high-mounted driver’s seat, although you look in vain for any bodywork beyond the base of the windscreen, such is the acute angle of the stubby bonnet. The view out back, meanwhile, is hampered somewhat by the substantial pillars and a shallow rear window within the tailgate. Accommodation up front is excellent, with the i3 imparting an airy and upbeat ambiance.
The decision to eschew a conventional steel monocoque in favour of a more advanced combination of aluminium, carbonfibre and steel construction for the i3 required a big investment in production infrastructure, but it has allowed BMW to bring its first dedicated electric car to market with a kerb weight that undercuts the competition at just 1195kg. By comparison, the similarly sized Nissan Leaf hits the scales at 1525kg, while the smaller Renault Zoe weighs 1390kg.
Further weight-saving measures are evident throughout; the outer body is a combination of thermoplastic panels, the windows use thinner glass than you find in the more traditional BMW models, the chassis uses largely bespoke aluminium components and selected interior trims, including the top of the dashboard, go largely untreated.
As well as being relatively light, the advanced construction used by the i3 also helps endow it with what BMW describes as class leading rigidity. This inherent structural strength has allowed designers to do away with traditional B-pillars and permit the use of coach style rear doors. It’s meant to easy entry to the rear. However, a combination of the high-mounted floor and curvature of the roof makes getting in a more difficult exercise than it would appear. The stubby rear door also boasts fixed windows.
The electric motor used by the i3 is mounted within its own sub-frame, which forms part of the rear axle assembly. It is coupled to a gearbox that provides uninterrupted progress owing to the fact that it boasts just a single ratio. Drive is sent to the rear wheels with the choice of three modes: Comfort, Eco Pro and Eco Pro Plus - the latter of which acts as an energy-preserving mode by limiting top speed to 50mph, reducing the performance of the air conditioning and, in combination with the most advanced optional navigation system, provides routing on roads with favourable topography. Also on board are traditional safety features such as traction, dynamic stability and cornering brake control.
