BMW i3 Concept.
The Megacity Vehicle.
The BMW i3 Concept with eDrive is an uncompromisingly sustainable vehicle designed for urban areas. Driven purely by electric power and purpose-built to meet the demands of sustainable and emission-free mobility it embodies an intelligent form of urban transportation and commuting.
BMW i3 CONCEPT COUPE:
BORN ELECTRIC. NATURALLY INTELLIGENT.
The BMW i3 Concept Coupe recently celebrated its European premiere in Geneva alongside the BMW i8 Concept Spyder in a show of the present state of design, development and innovation.
Since 2008, the BMW Group has been investigating customer needs with regards to electric driving within the world's largest e-mobility field trial. As part of the test process, more than 20 million kilometres (12.5 million miles) of testing by more than 1,000 pilot customers in ten countries was conducted and dynamically assessed. The findings show that the distances covered by electric vehicles differ only slightly from the distances covered by conventional ones, at an average of somewhat over 40 kilometres (25 miles) a day. Based on this fact as well as findings on drivers' charging patterns and the general importance of public charging station locations to drivers, BMW i set out to design the BMW i3 Concept Coupe.
The BMW eDrive: connecting space between home, office and countryside.
Today, thanks to intelligent BMW eDrive technology, the BMW eDrive is as tailored to one's drive through the city as it is comfortable with longer, out-of-town journeys. A specially developed high-voltage, lithium-ion battery powers this drive system and all other vehicle functions, once more setting new benchmarks in energy efficiency. The battery's intelligent heating-cooling system ensures that its energy output (and hence the vehicle's range) is less affected by temperature fluctuations. Reducing the energy needed to run the BMW i3 Concept Coupe's various intelligent electrical components was also at the forefront of engineering priorities. Subsequently, the vehicle's cabin heating saves 30% of energy compared to conventional electrical heating systems, while the internal and external lighting employ energy-saving LEDs.
These are just two details that make a significant contribution to the vehicle's 80 to 100 mile range. In addition, the use of various driving modes – as seen in the image below – can boost the range by up to 25%. The "EcoPro" mode mean that when taking off to local destinations, the Coupe's driver can comfortably secure the vehicle range.
Range Extender: E-DRIVING FOR THE LONG RUN.
As the world's first fully networked electric vehicle, the BMW i3 Concept Coupe repeatedly updates its driver with realistic estimates of the car's range. An optional range extender – as part of the completely electrically driven BMW i3 Concept Coupe – almost doubles the electric driving range and makes e-mobility hassle-free.

BMW i3 Concept Coupe.
Born Electric. Naturally intelligent.
The BMW i3 Concept Coupe is designed to integrate technological innovations via ConnectedDrive.
The BMW i3 Concept Coupe’s electric engine generates an output of 170 hp at 250 lb-ft of torque by transferring anonset of power via a fixed ratio transmision to the rear wheels. The e-motor gathers its energy from powerful lithium-ion batteries, which are smoothly integrated into the vehicle’s under body. Three energy modes – COMFORT, ECO PRO and ECO PRO+ – allow the driver to choose from maximum ride comfort, extended range and maximum range, again customizing the driving experience.
The coupe is equipped with the BMW ConnectedDrive navigation system that is consistently customized to the needs of e-mobility. A central piece of this navigation feature is a dynamic range indicator that takes into account all relevant factors such as battery charge and driving style, as well as topographic conditions or even the current traffic situation. Upon the driver’s request, a charging station located near the destination is displayed The system also informs its driver how long the battery needs to be charged to complete the return journey or to continue on to another destination. With this comprehensive approach to navigating an urban environment, the BMW i3 Concept Coupe driver’s mobility can be managed with unique precision, reliability and comfort.
Synchronized with your city: the BMW i3 Concept Coupe.
BMW ConnectedDrive remote app.
With unique ConnectedDrive features developed specifically for BMW i, electric mobility is not only tailpipe emission-free but also designed to be hassle-free. By using the BMW ConnectedDrive remote app, available for iOS and Android, a driver can access all vehicle data and route information from a smartphone anytime, anywhere.
If the BMW i3 Concept Coupe is connected to a charging station, its driver can start or end the charging process remotely or even control it with a timer. One can choose a destination via mobile phone and subsequently have it transferred to the vehicle. Constant connectivity to the outside world reveals itself within the vehicle in two key displays that relay information in 3D, high definition graphics. In this way, the driver can receive relevant information concerning route, range and accessible charging stations along the way or at the destination.
BMW i takes the urban experience of mobility beyond the vehicle itself, as we have seen more recently with new mobility services such as DriveNow and ParkNow. Linking life on the go with the in-car experience, makes driving in megacities easier, more enjoyable and efficient.
BMW i3 Concept. The state of sustainability.
With the use of renewable resources, the latest version of the BMW i3 Concept represents a new benchmark for sustainability and provides an insight into the interior design of the BMW i3 series vehicle.
The interior of BMW i3 Concept is characterized by the visible use of natural resources such as European eucalyptus wood. The use of natural materials emphasizes the premium standard of BMW i while conserving resources.
The leather used in the interior is tanned using a natural process derived from olive leaves. The olive leaf extract provides natural protection against fading and wear while giving the leather a unique look and unmistakable character. The cowhide from southern Germany is not only environmentally friendly, but also produced for maximum durability.
The wood used in the dashboard is made entirely of timber grown in Europe and certified as 100% sourced from responsible forestry. By crafting the wooden components in Europe, BMW ensures short delivery routes and sustainability in the production stages. The natural substances used in the finish also lend the wood a sophisticated look and unique coloration.
The BMW i3 Concept is an impressive demonstration of the holistic BMW i approach to sustainability. Compared to a highly efficient vehicle in the same class powered by an internal combustion engine, the BMW i3 Concept is estimated to reduce its’ CO2 footprint by one third over its entire product life cycle. Innovations in the development, manufacturing and recycling processes allow BMW i to set new standards in sustainability along the entire value chain.
BMW i3 Concept – Sustainable Urban Mobility.
The BMW i3 Concept is a designed all encompassing concept, with every detail conceived and optimised to fulfil its eventual purpose. Its innovative LifeDrive architecture renders the BMW i3 Concept light, safe, spacious and dynamic. Innovative use of materials and intelligent lightweight design, moreover, not only enable the BMW i3 Concept to travel long distances on a single charge, they also provide superb safety in the event of a collision and help give the car its excellent driving dynamics.
The eDrive technology consisting of an extremely agile electric motor developed and built by BMW, innovative battery technology and an intelligent engine management system. Makes the BMW i3 Concept extremely agile and a joy to drive. The electric motor over the rear axle – which generates output of 125 kW/170 hp and impressive torque of 250 Nm (184 lb-ft) from a standstill – and a small turning circle combine to deliver pleasingly dynamic driving characteristics. The BMW i3 Concept accelerates from 0 to 60 km/h (37 mph) in under four seconds and from rest to 100 km/h (62 mph) in less than eight seconds.
The Life module conjures up a generous feeling of space inside the car. Select materials lend the open and airy cabin a lounge-like character. The use of renewable raw materials is another defining characteristic of the interior, offering passengers a further means of "experiencing" the sustainability of the vehicle. Parts of the instrument panel and door panelling are visibly made from natural fibers, while the naturally tanned leather of the seats creates a lounge-style ambience. With four seats, wide-opening opposing "coach" doors, a trunk capacity of around 200 litres and an additional functional compartment in the front, the BMW i3 Concept is equipped for the demands of everyday use.
Innovative connectivity functions create a seamless connection between the BMW i3 Concept and its customers' lives outside the car. Remote functions accessible via a smartphone enable owners to find their vehicles, locate nearby charging stations, allow battery charging and preconditioning at the touch of a button, and supply information on the current status of the vehicle. Meanwhile, intelligent BMW ConnectedDrive assistance systems ease the stress on drivers in monotonous city driving situations and allow them to arrive at their destination more safely and in a more relaxed state of mind.
BMW i3 Concept – compact, agile, sustainable.
The design of the BMW i3 Concept reveals the car’s qualities the first time you set eyes on it. The BMW i3 Concept represents the dynamic interpretation of an impressively practical vehicle.
Dynamic and compact proportions showcase the agility of the BMW i3 Concept. From the side view, the window graphics and door sills combine to create a dynamic wedge shape, giving the car the feeling of pushing forward before it even turns a wheel. From the outside, a flowing silhouette hints at the extraordinarily generous levels of space on offer in the interior, while short front and rear overhangs make parking in tight spaces that much easier. Practicality gets another boost from the “coach doors”, whose opposing construction creates a fresh new way of accessing the large, open spaces of the interior.
Extensive glass surfaces and black elements like the window surrounds and door sills give the vehicle a feeling of lightness and, together with the exposed carbon structures, draw attention to its low weight. Large narrow 19-inch wheels add further impact to the dynamic side profile.
The striking front end.
The front end of the BMW i3 Concept has a very clear and uncluttered design. The dominant element here is the strikingly molded kidney grille which has the hallmark BMW i blue background and – thanks to the car's all-electric drive system – is totally blanked off. Below the kidney grille the silver-coloured layer lends the sculptural front apron its form. Black surfaces identify the functional areas of the front end, such as the load compartment under the hood and the air inlets.
Clearly defined AirCurtains also lend visible expression to the honed aerodynamics of this BMW i model. The eye-catching LED headlights usher in a fresh take on BMW light design. Along with the strikingly formed kidney grille, the LED-backlit U-shaped lines form an important part of the arresting new BMW i face.
The functional back end.
The large, rear window offers optimum access to the luggage compartment, and the roof pillars stand upright to create as much space as possible in the interior. The rear window is also home to the tail lights, which are U-shaped (like the headlights) and appear to be floating in the glass. Behind it lies an extremely versatile boot area, whose capacity can be further increased by folding down the rear seats.
The wide, silver-colored rear diffuser marks the body's lowest edge and allows the driver to experience the car's efficient aerodynamics. Bordered by a blue layer, the diffuser tapers heavily towards the road and appears to continue underneath the car. The form of the diffuser underlines the car's powerful stance. A sportier version can be found on the BMW i8 Concept, forging a link between the two models.
Self-supporting and light – the interior.
The version of the LifeDrive architecture that underlies the BMW i3 Concept opens up totally new avenues in interior design. There is no center tunnel bisecting the cabin and the interior thus creates a very free, open and airy impression.
The passengers sit in a raised “semi-command” position which provides a good view over the hustle and bustle of city traffic and, at the same time, eases access to the seats.
The full-width seat benches in the front and rear create a new and connecting feeling of space for the passengers in the light interior. This layout also allows them when parked to move from one side of the car to the other and, if necessary, to all exit the car comfortably on the same side. This represents a major boost to comfort in tight parking spaces and when access to one side of the parked car is impeded.
A distinctive element of the light interior is the freestanding steering column. All the driving-oriented controls – such as the instrument cluster, start/stop button and gearshift lever – can be found here, rendering a center console superfluous. Behind the steering column the extremely intricate yet extensive instrument panel spans the interior. It begins at the air vents next to the steering wheel, continues in a line around the steering column, including the radio and climate controls, and finally moves on to the front passenger. Shortly before the front passenger door it then shears upwards, heads back towards the center of the interior and reaches the end of its journey in the central information display (CID) monitor positioned above the control panel for the radio and climate system. Around the displays, by contrast, the instrument panel design has large, wide surface sweeping prominently into a narrower and more delicate counterpart, before culminating in another wide section. The CID and control unit therefore present an attractive contrast to the clear, precise borders of the instrument panel.
The area around the instrument panel, the doors and the floor area of the BMW i3 Concept also feature contrasting materials. The natural origins of the high-strength dark anthracite material made from compressed and coated plant fibers are clearly evident and showcase the light, high-quality and beautifully crafted elements of the interior to optimum effect.
Connectivity – the linking up of the driver and passengers with the outside world and information superhighway – plays an important role in the BMW i3 Concept. Large displays act as interfaces between the vehicle and the outside world. The instrument cluster, meanwhile, emerges out of the steering column directly in front of the driver. Its freestanding design generates a very open feel around and above the driver’s head. Meanwhile, the central information display (CID) curves out of the black technical layer of the instrument panel’s upper section towards the passengers.
On another level, the highly technical-looking display graphics of the instrument cluster and CID lend visual form to the BMW i3 Concept’s electric drive philosophy. All the information is displayed in the high quality and visually appealing fashion you would expect from BMW.
The LifeDrive architecture of the BMW i3 Concept.
Both the BMW i3 Concept and the BMW i8 Concept feature the LifeDrive architecture, but the geometric implementation of the concept differs in the two concepts having been adapted to suit their different usages.
The BMW i3 Concept features a horizontal-split variant of the LifeDrive concept. Here, the Drive module provides the solid foundations for the Life cell, which is simply mounted on top. The reason for this functional rendition of the LifeDrive architecture is the large battery. In order to ensure the greatest possible electric range, the battery in the BMW i3 Concept is correspondingly large. The most space-efficient place to store the battery cells was under the car's floor section, where they occupy the whole of the module's central section, giving the car optimum weight distribution and a low centre of gravity. The battery is housed in an aluminum frame, which protect it from external impacts. Crash-active structures in front and rear provide the necessary energy absorption in the event of a front- or rear-end collision. The eDrive system is, as a whole, much more compact than a comparable combustion engine, cleverly accommodating the electric motor, gear assembly and drive electronics – in space-saving fashion – within a small area over the ear axle.
The integration of all the drive components within the Drive module removes the need for a center tunnel bisecting the interior through which power would previously have been transferred to the rear wheels. The BMW i3 Concept therefore offers significantly more interior space than other vehicles with the same wheelbase and – through solutions such as a full-width seat bench – also allows the interior to be adapted extremely effectively to the needs of urban mobility. The BMW i3 Concept offers comfortable accommodation for four passengers and, with around 200 litres of trunk space, room for their luggage as well.
The chassis of the BMW i3 Concept is also ideal for city driving. Its enviably small turning circle and direct steering responses result in outstanding agility, notably at low speeds.
All-electric – the BMW i3 Concept.
The electric motor of the BMW i3 Concept is designed primarily for operation in an urban environment, developing 125 kW/170 hp, with peak torque of 250 Nm (184 lb-ft). Typically an electric motor develops, maximum torque from standstill, in contrast to an internal combustion engine where torque increases with engine rpm.
This makes the BMW i3 Concept highly agile and provides impressive acceleration. The BMW i3 Concept accomplishes 0-37 mph in under four seconds and 0-62 mph in under eight seconds.
At the same time the abundant torque is delivered over a very large rpm range resulting in very smooth power delivery. The single-speed gearbox provides optimal power transmission to the rear wheels and accelerates the BMW i3 Concept to an electronically governed 93 mph without loss of power. The electric drive also allows for deceleration by means of the accelerator pedal. After the driver eases up on the accelerator, the electric motor acts as a generator, converting the kinetic energy into electricity which is then fed back into the battery. Energy recuperation generates a braking effect which makes a significant contribution to vehicle deceleration.
A coasting mode makes this unique "single-pedal control" of acceleration and braking using only the accelerator even more user-friendly. When the driver eases off the pedal, the electric motor's zero torque control keeps the drive train disconnected as long as the pedal is in this position. The vehicle now coasts without consuming power, driven by its own kinetic energy.
eDrive – Compact, efficient and powerful.
Thanks to eDrive technology, electric mobility provides a unique, exhilarating driving experience. The electric motor of the BMW i3 Concept not only offers attractive driveability; its innovative nature is particularly evident in the favorable power-to-size ratio. As a result of continuous development and refinement, the space requirements of the electric motor used in the BMW i3 Concept have been reduced by 40 per cent compared with the motor used in the MINI E. This newly developed e-motor is already being used today in the BMW ActiveE. This compact drive unit is mounted over the rear axle, together with the power electronics, transmission and differential, and does not intrude into the interior. The power needed to drive the vehicle and to operate all other vehicle functions is supplied by specially developed lithium-ion battery cells. The BMW i3 Concept's battery system is optimized which significantly reduces the extent to which external factors can influence the vehicle's power. A intelligent liquid heating/cooling system keeps the battery at its optimal operating temperature at all times, which helps to significantly boost the performance and life expectancy of the cells.
The battery can be fully recharged in four hours using an installed wallbox. If a DC-fast charger is used an 80 per cent charge can be achieved in around 30 minutes.
Range extender increases the driving range.
As the MINI E field trial demonstrated, over 90 per cent of the mobility requirements of the MINI E field trial participants could be met with the range of the MINI E. However, some customers want a longer driving range, or want their vehicle to be as flexible as possible. The BMW i3 Concept therefore offers an optional range extender, the REx, which allows the driving range to be increased. REx, a small, very smooth-running and quiet petrol engine, drives a generator which maintains the battery charge level to ensure that the vehicle can continue to run on electric power.
