In the BMW i3 – the first series-produced model by BMW i – zero-emission mobility in a premium car package proves to be a recipe for pure driving pleasure. The first BMW Group model running on electric power alone offers customers totally new and groundbreaking ways to experience driving pleasure, sustainability and connectivity on city roads. The visionary design of the BMW i3 showcases both BMW’s customary sporting capability and the efficiency of a four-seater with authentic clarity. Its innovative vehicle concept, including a passenger compartment made from carbon-fibre-reinforced plastic (CFRP), combines lightness, stability and safety with extraordinary spaciousness. Meanwhile, the driver assistance systems and mobility services from BMW Connected Drive and the 360° ELECTRIC services – all developed specially for BMW i – turn zero-emission urban mobility into a compelling everyday driving experience.

The electric motor powering the BMW i3 generates a maximum output of 125 kW/170 hp and peak torque of 250 Newton metres (184 lb-ft). Its instantaneous power flows to the rear wheels via a single-speed transmission. The motor sources its energy from lithium-ion storage cells integrated into the car’s underfloor section. The significantly lower centre of gravity of the i3 – the result of the low, central placement of the battery units – and even weight distribution make an additional contribution to the car’s agile handling. The battery gives the car a range in everyday conditions of 130 – 160 kilometres (81 – 99 miles) when fully charged from a conventional domestic power socket, BMW i Wallbox or public charging station.

Sustainability plays a prominent role for the BMW Group in this area also. The BMW i3 was the first vehicle project for which sustainability objectives were agreed that were pursued with the same vigour as cost, weight or quality objectives. The aim is also to reduce the environmental impact of production as much as possible, focusing on aspects such as energy supply and water consumption, solvent emissions and waste treatment.

Carbon fibre production with wind and hydroelectric power.

Even for the manufacture and processing of carbon fibre-reinforced plastic (CFRP), BMW attaches the utmost importance to conservation of the environment and resources, and the use of a renewably generated power supply where possible. The BMW Group therefore has control over all process steps, from fibre production to the recycling of fibres and composites. This is illustrated particularly well by the ultramodern CFRP production chain, which starts in Moses Lake in the U.S. and passes to Germany in Wackersdorf and Landshut and on to final manufacturing in Leipzig. In Moses Lake, for example, the required electricity is generated in an environmentally friendly way from 100 per cent hydroelectric power, while at the Leipzig works the entire electricity requirement is met using self-generated wind power.

BMW works in Leipzig: 100 per cent of electricity generated by wind power.

The BMW works in Leipzig is unique in a number of ways. The power required for production is generated directly on site by wind power. In fact, the four wind power systems installed on the works grounds generate more electricity than is needed to manufacture the BMW i models in Leipzig. In addition to the CO2-free power supply, the works sets other records: compared with the already highly efficient BMW production average, a further 50 per cent energy and 70 per cent water were saved in BMW i manufacture.

CFRP series production: high process safety, fast cycle times.

In the BMW works in Leipzig, series production of the BMW i3 is setting new standards, and not just in environmental protection. The use of carbon components is unique in automotive mass production because large-scale use of CFRP was previously considered too expensive, and processing and manufacture too complex and insufficiently flexible. However, after over ten years of intensive research and optimisation of processes, materials, systems and tools, the BMW Group is the only automobile manufacturer to have the necessary expertise to use CFRP in mass production. The process is unique, and the cycle times unusually short even for complex CFRP components. The same is true for the proprietary bonding techniques developed in-house, which are used to bond the individual components together in the bodyshop in a fully automated process.

First recycling concept of its kind worldwide.

In the course of developing the BMW i, the BMW Group eventually devised the first recycling concept of its kind worldwide for CFRP components, body parts and sorted production waste that was suitable for series production. The valuable recyclable materials are reused in different processes and channelled back into the production process or used in other applications in order to save valuable resources. BMW has even devised useful repurposing for scrapped batteries.

E-mobility: the road is clear.

With a range of up to 160 kilometres, the BMW i3 meets the mobility demands of its users in urban areas. Charging is extremely simple and is possible at home, at work or at public charging stations. In addition, BMW i offers a comprehensive range of products and services under the 360° ELECTRIC label that meets individual customer needs. BMW i is also exerting great pressure together with different partners to advance the expansion of the public charging infrastructure, including convenient reservation and payment systems.

eDrive: reliable, safe and long lasting.

It goes without saying that the reliability and safety of electrical components are very important to the BMW Group. It is good to know that the lithium ion battery of the BMW i3 lasts at least the full lifetime of a vehicle. This is achieved through intelligent battery management and an effective heating/cooling system developed by BMW, for example. Like all BMW vehicles, the BMW i3 also meets the company’s strict demands, which exceed the statutory requirements.

Ease of service and repair to a renowned standard.

Even in the highly unlikely event of a fault, defective components can be identified, and individual modules or the entire battery replaced. The same applies to damage caused to the body resulting from an accident, as ease of repair was high on the list of technical specifications for the BMW i3 even during its design phase. BMW therefore developed time-saving repair methods specially for the plastic panelling and CFRP components of the BMW i3. As a result, all of the accident repair costs are similar to those of a BMW 1-Series
