Creating an entire sub-brand around a new philosophy of automotive development, BMW rolled-out their first vehicle from BMW i in 2014. The BMW i3 compact hatchback was introduced to produce a meaningful impact on how luxury motoring can combine with electrified motoring. The vehicle's construction emphasizes the use of lightweight methods and materials. A carbon fiber reinforced plastic passenger cell delivers weight-savings as well as high performance in the event of a crash. The BMW i3 provided buyers with the choice of an all-electric version capable of 81 miles per charge or one equipped with a Range Extender. Generically known as a plug-in hybrid, the BMW i3 featuring the Range Extender can travel up to 150 miles thanks to a two-cylinder gasoline engine. A vehicle with an environmentalist twist, the BMW i3's cabin incorporated items such as naturally-tanned leather, seat covers made almost entirely of recycled polyester and eucalyptus wood trim sourced from certified, responsible forestry.
