The BMW ActiveE is a demonstration electric car based on the BMW 1 Series small family cars. It is the second vehicle after the Mini E to be developed under BMW Group’s Project i. The electric drive system is the latest addition to BMW’s EfficientDynamics programme.〔 The US Environmental Protection Agency official range is , with an energy consumption of 33 kW·h/100 miles, and the agency rated the ActiveE's combined fuel economy at 2.3L/100 km (102 miles per gallon gasoline equivalent). The four-seater, rear-wheel drive ActiveE was unveiled at the North American International Auto Show in Detroit in January 2010. Deliveries of the ActiveE for field testing in the U.S. began in January 2012, after the Mini E trial ended. A total of 1,100 vehicles will participate in the program worldwide, 700 will be allocated for the U.S. trial and 35 to a trial in China. Participants in the Mini E trial had priority to lease the new electric car.〔 Production began at BMW's Leipzig plant in July 2011.〔 After the field trial of the Mini E, BMW took reservations for drivers, who BMW calls "Electronauts", in mid-2012. The field trial of the ActiveE started in early 2012. BMW has stopped accepting reservations for the ActiveE, and has leased out all of their ActiveE cars. The lease details are similar to that of the Mini E lease details, a two-year limited lease with free maintenance. The lessee must complete online surveys and take their ActiveE into their local BMW dealership for analysis and service periodically. Once the ActiveE program ends, all ActiveE cars will be taken off of the road. Lessees will turn their ActiveE vehicles back into BMW, and will not be able to purchase them back off of lease. The cars will be donated to tech schools or museums for analysis and dissassembly, as well as for display purposes. ==Specifications== The electric car has a 32 kWh lithium-ion battery pack developed in cooperation with SB LiMotive and an all-electric range of . The ActiveE takes 8.5 seconds to reach and its maximum speed is electronically limited to .〔 The ActiveE has an EcoPro mode that retards throttle response, shuts down the defrosters and tweaks the climate control to boost efficiency by up to 10%.〔 The ActiveE has a electric synchronous motor integrated into the rear axle to power the rear wheels, the same configuration that will be used in the BMW i3. The motor weighs and delivers of torque. The curb weight of the ActiveE is , nearly heavier than a BMW 135i, but the ActiveE has a 50:50 weight distribution. The liquid-cooled storage cells are located under the hood, in the transmission tunnel and where the fuel tank would normally reside. The rear-mounted electric motor reduces the trunk space to versus in the standard BMW 1 Series.〔 Based on the lessons learned by BMW regarding cold weather problems during the Mini E field testing, the ActiveE will have liquid cooling and liquid heating, with a thermal management system that is expected to keep ActiveE batteries at an optimal performance temperature.〔〔 The ActiveE comes with all the standard ConnectedDrive features including navigation, Sirius satellite radio, Google Local Search and Send-to-Car functionality, and a range of connected apps that normally come in higher-spec models. Also included with the ActiveE is a reworked BMW MyRemote application for the smartphones that allows remote locking and unlocking, horn and headlamp activation, and GPS-based CarFinder that allows the user to find the E within . The smartphone app also allows the user to find charging stations, get range information and pre-heat or cool the car to help extend the range.〔 Like other electric vehicles with use of the motor for regeneration of battery power, the Active E has a different driving experience from a car powered by an internal combustion engine: taking pressure off of the accelerator pedal results in deceleration as the motor brakes and regenerates electricity. Many drivers rarely use the brakes except to hold the car at a stop. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BMW ActiveE」の詳細全文を読む スポンサード リンク
