The BMW Group will be the world’s first manufacturer of premium automobiles to deploy a fleet of some 500 all-electric vehicles for private use in daily traffic. The MINI E will be powered by a 150 kW (204 hp) electric motor fed by a high-performance rechargeable lithium-ion battery, transferring its power to the front wheels via a single-stage helical gearbox nearly without a sound and entirely free of emissions. Specially engineered for automobile use, the battery technology will have a range of more than 240 kilometers.

The MINI E will initially be made available to select private and corporate customers as part of a pilot project in the US states of California, New York and New Jersey. The possibility of offering the MINI E in other markets is currently being considered. The MINI E will give its world premiere at the Los Angeles Auto Show on November 19 and 20, 2008.

The MINI E’s electric drive train produces a peak torque of 220 Newton meters (162 lb-ft), delivering seamless acceleration to 100 km/h in 8.5 seconds. Top speed is electronically limited to 152 km/h.
By introducing the MINI E, the BMW Group is underscoring the resolve with which it works towards reducing energy consumption and emissions in road traffic.

The BMW Group aims to start series production of all-electric vehicles over the medium term as part of its Number ONE strategy. The development of innovative concepts for mobility in big-city conurbations within the scope of “project i” has a similar thrust, as its objective also includes making use of an all-electric power train.
The energy storage unit: cutting-edge lithium-ion technology engineered specifically for use in the MINI.

Based on the current MINI, the car will initially be available as a two-seater. The space taken up by back-seat passengers in the series model has been reserved for the lithium-ion battery. When in use in the zero-emissions MINI, the battery unit combines high output with ample storage capacity and a small footprint with power ratios that are unrivalled in this field of application so far. The lithium-ion storage unit will have a maximum capacity of 35 kilowatt hours (kWh) and transmit energy to the electric motor as direct current at a nominal 380 volts. The rechargeable battery is made up of 5,088 cells grouped into 48 modules. These modules are packaged into three battery elements that are compactly arranged inside the MINI E.

The MINI E’s lithium-ion battery can be plugged into all standard power outlets. Its charge time is strongly dependent on the voltage and amperage of the electricity flowing through the grid. In the USA, users can recharge a battery that has been completely drained within a very short period of time using a wall box that will ship with every MINI E. The wall box will be installed in the customer’s garage, enable higher amperage, and thus provide for extremely short charging times. Wall boxes fully recharge batteries after a mere two-and-a-half hours.
 
 Mounted transversely under the MINI E’s hood, the drive train unleashes its full thrust from a dead standstill. The MINI E’s intense driving experience is augmented by its dynamic deceleration potential, which is also directly coupled to the accelerator pedal. As soon as the driver releases the gas pedal, the electric motor acts as a generator. This results in braking force, and the power recovered from the kinetic energy is fed back to the battery. This interaction ensures extremely comfortable drives – especially at medium speed with constant, but marginal, variation. In city traffic, some 75 percent of all deceleration can be done without the brakes. Making substantial use of this energy recuperation feature extends the car’s range by up to 20 percent.

At first glance, the MINI E is obviously an iteration of the brand. But its design, which is the blueprint for the zero-emissions two-seater, has been complemented by a number of visual cues that point to its revolutionary drive concept. All of the units produced for the pilot project will have the same paintwork and bear a serial number on their front fenders.
The MINI E’s coachwork sports an exclusive combination of metallic Dark Silver on all panels but the roof, which is clad in Pure Silver. What distinguishes the zero-emissions MINI is a specially designed logo in Interchange Yellow, depicting a stylized power plug in the shape of an “E” set against the silver backdrop. It has been applied to the roof, in smaller dimensions to the front and back, to the charger port lid, the dashboard trim, and – combined with the MINI logo – to the door jamb, in slightly modified form. The color of the roof edges, mirror housings, interior style cues and seat seams will match the logo’s yellow tone as well.

A 500-unit, limited-production MINI E series will be manufactured through the end of 2008.  The cars will change hands based on a one-year lease with an extension option. Monthly lease installments will cover any required technical service including all necessary maintenance and the replacement of wearing parts. At the end of the lease, all of the automobiles belonging to the project will be returned to the BMW Group’s engineering fleet where they will be subjected to comparative tests.

The MINI E’s energy storage unit emerged completely unscathed from all of the crash tests mandated by US standards, which are especially high.
Production of the approximately 500 cars will take place at the company’s Oxford and Munich sites and is scheduled for completion before the end of 2008. MINI’s UK plant will be responsible for manufacturing the entire vehicle with the exception of the drive components and the lithium-ion battery, with the brand’s series models rolling off its assembly lines concurrently. The units will then be transferred to a specially equipped manufacturing complex situated on BMW plant premises in Munich, Germany, where the electric motor, battery units, performance electronics and transmission will be integrated.

What it means
If BMW- the most brand-aware auto company on the planet - gets so publicly into the electric car game, that means that EVs are a serious business opportunity by now. As we all know, the Bavarians won’t accept defeat, no matter what, and this is a huge vote of confidence in the electric car’s future. Faced with a now questionable ‘performance’ strategy, a no-no during this financial tumult and economic hardship, the electric avenue allows the company to maintain its engineering leadership – and its much-vaunted ‘premium’ status without raising eyebrows. Some mass–marketed environmental creed doesn’t hurt either, something harder to do with the possible diesels. All in all, a very positive development with far reaching implications for the  auto retail, recharging infrastructure and even financial industries.
