German car manufacturer BMW has taken the warps off its new i3 and i8 electric cars at the Frankfurt Motor Show.
Part of a new sub-brand focused on efficiency and responsive driving, the cars are still concepts for now and will enter production in 2013.
A lightweight car made of aluminium and carbon fibre, the i3 is a pure electric car designed for shorter urban journeys.
Although the firm says that it will offer a petrol-powered range extending engine as an option, for now the car is solely powered by battery power.
BMW's i8 has a 1.5-litre petrol engine with electric power that can produce a combined 349 horsepower and 405lb.ft of torque.
It can manage 0 to 62mph in 4.6 seconds, and its top speed is 155 mph.
According to the firm, its fuel consumption stands at around 100mpg and CO2 emissions are just 66g/km.
Both cars can seat up to four occupants.
