BMW Vision Efficient Dynamics
Encyclopedia
The BMW i8, first introduced as the BMW Concept Vision Efficient Dynamics, is a plug-in hybrid under development by BMW
. The initial concept car was unveiled at the 2009 Frankfurt Motor Show, and the BMW i8 concept car
destined for production was unveiled at the 2011 Frankfurt Motor Show. The i8 has a 7.2 kWh lithium-ion battery pack which delivers an all-electric range
of 35 km (21.7 mi).
In 2010 BMW announced the mass production
of the Concept Vision Efficient Dynamics in Leipzig
beginning in 2013 as the BMW i8. The i8 is part of BMW's "Project i" and will marketed as a new brand, BMW i
, sold separately from BMW or Mini
. The BMW i3
and the BMW i8 will be the first models available from 2013. Other i models will follow.
is a plug-in hybrid with a three cylinder
turbodiesel
engine. Additionally, there are two electric motors with 139 horsepower
. It allows an acceleration
to 100 kph in 4.8 seconds and an electronically limited top speed of 250 kph.
According to BMW, the average fuel consumption
in the EU test cycle (KV01) is 3.76 liters/100 kilometers, (75.1 mpg imp), and has a carbon dioxide
emission rating of 99 grams per kilometer (1,3 l/100km and 33g CO2/km ; EU-PHEV ECE-R101). The estimated all-electric range
is 50 km (31.1 mi), and the 24-litre diesel tank extends the total vehicle range to up to 700 km (435 mi). The lightweight chassis is made mainly from aluminium. The windshield, top, doors and fenders are made from polycarbonate glass, with the body having a drag coefficient
of 0.22.
unveiled at the 2011 Frankfurt Motor Show has a 7.2 kWh lithium-ion battery pack that allows an all-electric range
of 35 km (21.7 mi). Its top speed is electronically limited to 250 kph and is expected to go from 0 to 100 kph (0 to 60 mph
) in 4.6 seconds. Under normal driving conditions the i8 is expected to deliver 80 mpgU.S. (34 km/L) under the European cycle. A full charge of the battery will take less than 2 hours using 220V.
The i8 combines the electric drive system of the BMW i3
, with a 129 hp electric motor
located in the front axle powering the front wheels and at the rear is a turbocharged 1.5-liter 3-cylinder gasoline engine producing 164 kW and 300 Nm (221 lb-ft) of torque. The result is a combined output of 349 hp. All four wheels provide regenerative braking. The location of the battery pack in the energy tunnel gives the vehicle a low centre of gravity, enhancing its dynamics. Together with the positioning of the motor and engine over the axles, the result is an optimum 50/50 weight distribution.
