BMW i8 Concept Spyder Revealed
The i8 Concept Spyder uses the same technology and components as its sibling, the BMW i8 Concept. Both cars are plug-in hybrids with an electric motor on the front axle and a turbocharged three-cylinder gasoline powered engine. The system output of the electric motor (131 hp / 96 kW) and the combustion engine (223 hp / 164 kW) is 354 hp (260 kW) with a peak torque of 405 pound feet (550 Nm ).
The lithium-ion battery, which is the same as in the BMW i3, was slightly modified for the i8 and is located in the “energy tunnel” between the front and the rear axle modules. To compensate for the additional weight of the batteries, BMW uses carbon-fiber-reinforced plastic (CFRP) for the Life module (passenger cell) of the car. Together with other components a perfect 50:50 weight distribution was achieved, which should endow the Spyder with characteristic BMW handling..
Looking at the performance figures, the i8 Spyder can go from 0 – 62 mph (0 to 100 km/h ) in five seconds and has an electronically limited top speed of 155 mph (250 km/h). It can cover a distance of 19 miles (30 km ) on electric power alone. It takes less than two hours to fully recharge the battery.
Thanks to innovative hybrid-technology and the new lightweight, the BMW i8 Concept Spyder offers the fuel economy of a small city car and the driving performance of a sports car. In the EU test cycle, the fuel consumption is only 3.0 l/100 km (78 mpg).
Simultaneously with the announcement of the BMW i8 Concept Spyder, BMW also announced that it had achieved an additional reduction of 70% in water use and a 50% drop in energy consumption per vehicle at its production plant inLeipzig. One hundred percent of the energy used comes from from renewable sources. Currently the BMW 1 Series and the X1 are built inLeipzig. These models will be joined by the BMW i3 in 2013 and the BMW i8 in 2014.
