Woodcliff Lake, N.J. –. The born electric BMW i3 represents a new era of electromobility. It is like no other car the world has ever seen. It offers visionary design, a ground-breaking vehicle architecture, dynamic performance and innovative connectivity. No other car represents such a holistic approach to sustainability throughout the value chain. The BMW i3 will go on sale in the US market in the second quarter of 2014. The battery electric model will have a base MSRP of $41,350, before any federal or state incentives, and before Destination & Handling fee (currently $925). The range-extender model will have a starting MSRP of $45,200. Again, this is before any federal or state incentives, and before Destination & Handling fee.
The new all-electric BMW i3 is a landmark in BMW’s mission to provide a completely sustainable, electric vehicle that still stays true to the Ultimate Driving Machine moniker. The BMW i3 is the first product of the new BMW i sub-brand, and is a truly purpose built electric car. It’s a new era for electro mobility at BMW.
The vehicle concept behind the BMW i3 was designed from the outset to incorporate an all-electric drive system. This has numerous advantages over “conversion” vehicles, in which the original combustion engine is swapped for an electric motor. The engineers can design whatever works best, in terms of construction, dimensions and configuration of the electric drive system’s components. The car’s development is dictated by the characteristics designed into the car by the development team and not by the constraints imposed by a pre-existing vehicle design. For example, the space in a conversion vehicle set aside for the fuel tank or exhaust system cannot be used. In the BMW i3 there is no need for this kind of compromise.
This leads to the LifeDrive architecture concept, which was purpose-built specifically for the BMW i3. It is comprised of two modules; the Life Module, and the Drive Module. Think of the Life Module as the passenger cabin, or greenhouse. It is the first-ever mass produced Carbon Fiber Reinforced Plastic (CFRP) passenger cell in the automotive business, and is a big factor in the cars efficiency. Carbon Fiber Reinforced Plastic is equally as strong as steel, while being 50% lighter, and 30% lighter than aluminum. The result is an electric car that weighs about 2,700 lbs (preliminary US figures).
Due to the lightweight, high tensile strength of CFRP, the passenger cell has added protection, and the battery has less work to do, which allows for the use of a smaller, lighter battery that saves even more weight, reduces charging time and increases range. The light weight design of the Life Module also lowers the BMW i3’s center of gravity, making it a more engaging and dynamic car to drive.
The Drive Module, which is constructed out of 100% aluminum, consists of the 22-kWh, 450 lb. lithium-ion battery, electric drive train, MacPherson strut and 5-link rear suspension system and structural and crash components. The battery mounted in the rear, close to the drive wheels, gives impressive performance characteristics while also providing better traction.
Another benefit of the LifeDrive architecture concept is that there is no space-consuming transmission tunnel running through the center of the car, like in most internal combustion powered cars, because of the separate Drive Module. This gives the BMW i3 the interior space of the BMW 3 Series, while only having the footprint of the much smaller BMW 1 Series.
Even the vehicle’s key is sustainably manufactured. The source material of the new bio-polymer key is based on castor oil pressed from castor seeds. The owner’s manual is also made from renewable resources.
The interior is made using high quality renewable sources and recycled materials. The BMW i3 has the Next Premium interior, which blends sustainable resources with a premium feel for the same interior quality as the BMW 5 Series Sedan. 25% of the plastics in the interior and 25% of the thermoplastic parts on the exterior are made from either recycled materials or renewable sources.
According to studies carried out as part of BMW’s Project i, involving more than 1,000 participants and conducted over some 12.5 million miles, it was revealed that the average daily distance covered was around 30 miles. The BMW i3 will be able to travel 80 to 100 miles on a single charge. This can be increased by up to approximately 12% in ECO PRO mode and by the same amount again in ECO PRO+ mode. It is able to recharge in only 3 hours with the use of a 220V Level 2, 32-amp J1772 charger. The SAE DC Combo Fast Charging, which charges the BMW i3 up to 80% in 20 minutes, and 100% in 30, can be had as an option.
In order to reduce range anxiety, a rear-mounted 650cc, 34 hp, two-cylinder, gasoline-powered Range Extender generator is available, which roughly doubles the vehicle’s range. When the battery gets to a certain level, the Range Extender starts and maintains the battery’s current state of charge. The Range Extender never directly drives the vehicle’s wheels. The Range Extender adds roughly 330 lbs. to the vehicle curb weight and has a fuel capacity of 2.4 gallons.
Since 1999 according to the DOE, average gasoline prices in America have increased from approximately $1.136 to $3.618, or about a 218%. In the same time, the pricing of electricity has increased from 6.6 cents to 9.9 cents, a change of only 50%, making electricity a far more attractive commodity from a pricing standpoint.
