BMW i3 & i8 Concept Cars
BMW i3 Concept ? dynamic, compact, emission-free.
The BMW i3 Concept 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.
"This automotive concept uses a new architecture which showcases all of its new possibilities and potential. It is the world's first premium electric vehicle." (Andreas Feist, Head of vehicle project BMW i3)
BMW i3 is a well-resolved all-round concept, with every detail conceived
and optimized to fulfill its eventual purpose. Central to its design is
the innovative LifeDrive architecture, the key to the BMW i3 Concept's
appeal as a light, safe and spacious car. Innovative use of materials
and intelligent lightweight design not only enable the i3 Concept to
travel long distances on a single charge and provide superb safety in
the event of a collision, they also help give the car its excellent
driving dynamics. The secure arrangement of the battery in the Drive
module gives the vehicle a very low center of gravity and optimum weight
distribution. 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
crisp driving characteristics and give the driver a very immediate
experience of the BMW i3 Concept's lightweight design. 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
extremely direct sensation at the wheel is expressed in outstanding
agility at low speeds and during turning maneuvers, and makes parking
in tricky situations that much
Life module conjures up a feeling of space inside the car more generous
than even the latest conversion vehicles can offer. 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. Elements of the instrument panel and door paneling are visibly made from natural fibres, while the naturally
tanned leather of the seats creates a lounge-style ambiance. Together,
these materials provide an appealing contrast to the clear, "floating"
forms of the instrument panel and door elements, and lend the interior a
strikingly modern feel. With the drive components located in the Drive
module, there is no centre tunnel running through the passenger
compartment. This allows the two front and two rear seats to be
connected with each other by a continuous seat surface, which allows for
ease of entry and exit via the front passenger side of the car and
means you can park up close to walls, for example. With four seats,
wide-opening opposing "coach" doors, boot capacity of around 200 litres
and an additional functional compartment in the front, the BMW i3
Concept is neatly equipped for the demands of everyday
However, the electric motor developed by BMW and the optimized
lightweight design of the LifeDrive architecture cannot take all the
credit for imbuing the car with such efficiency and enabling it to
travel such long distances on each charge. Indeed, the ability of the
car to recoup energy while on the move and special range-extending
functions, such as ECO PRO mode, also add miles to the clock. With ECO
PRO mode activated, all the vehicle functions operate with maximum
efficiency. For example, the accelerator mapping is tweaked to limit the
output summoned when the driver flexes his right foot, and the climate
control functions also use as little energy as possible. Added to which,
sophisticated aerodynamics and slim, low rolling resistance wheels minimize resistance to the car's forward progress and maximize its
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, flag up 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 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 i8 Concept ? emotional, dynamic and efficient.
The BMW i8 Concept and the fascinating approach that underpins it embody the vision of a sustainable contemporary sports car brought to life. Its innovative plug-in hybrid concept combines the modified electric drive system from the BMW i3 Concept ? fitted over its front axle ? with a high-performance three- cylinder combustion engine producing 164 kW (220 hp)/300 Nm (221 lb-ft) at the rear. The electric motor in the BMW i8 Concept is a full-capability unit which can also power the car on its own, if required. However, working in tandem allows the two drive systems to display their respective talents to the full, delivering the performance of a sports car but the fuel consumption of a small car.
Acceleration of 0 to 100 km/h (62 mph) in under five seconds combined with fuel consumption in the European cycle of under three litres per 100 kilometres (approx. 94 mpg imp) and average customer fuel consumption of between five and seven litres per 100 kilometers (40.4 ? 56.5 mpg imp) ? even when driven hard ? are figures currently beyond the capability of any vehicle powered by a combustion engine of comparable performance. Thanks to its large lithium-ion battery, which can be charged from a domestic power supply, the BMW i8 Concept can travel up to 35 kilometers (approx. 20 miles) on electric power alone. A large proportion of short everyday journeys can therefore be completed with zero emissions. The car's electric-only mode allows it to enter emissions- capped central areas of cities with access restrictions in place for petrol or diesel-powered vehicles. The i8 Concept's efficiency rating is further enhanced by its ability to generate energy at both axles. The electric motor at the front axle recoups maximum energy every time the driver brakes, while a high-voltage alternator hooked up to the combustion engine charges the battery, if required. Added to which, the 2+2-seater offers enough space for four people, giving it a high level of everyday practicality.
The emotional design of the BMW i8 Concept ensures its qualities are clear for all to see. Its dynamic proportions give the BMW i8 Concept the appearance of surging forward before it even turns a wheel and lend visual form to its extraordinary performance. The sophisticated concept behind the upward- swiveling doors fixed to the A-pillars underlines the car's sporting capability and opens up access to the front and rear seats at the same time.
A series of air inlets allow the air to flow through and around the vehicle to optimum effect, ensuring extremely low drag. They also add visual emphasis to these advanced aerodynamics. Airflow plays an extremely important role at the rear of the vehicle as well. Intakes behind the passenger cell and at the rear provide a cooling flow of air through the engine compartment, while outlets in the rear diffuser and the flow of air around the rear wheels ensure the car is extremely efficient in terms of lift and downforce at both axles.
The LifeDrive architecture of the BMW i8 Concept has been carefully adapted to enhance the vehicle's sports car character, and therefore to deliver unbeatable performance and excellent driving dynamics. The motor in the front axle module and combustion engine at the rear are connected by an "energy tunnel", which houses the high-voltage battery. This gives the car a low center of gravity ? and the dynamic benefits that come with it. The positioning of the electric motor and engine over their respective axles and the space-saving and well-balanced packaging of all components result in an optimum 50/50 weight distribution.
The weight of every component inside the BMW i8 Concept has been minimized down to the very last detail, allowing the extra weight of the electric drive system and battery to be canceled out. The BMW i8 Concept therefore presents the ideal environment in which to sample this very special drive concept on the road. The passengers sit ? in typical sports car style ? in an extremely low and enclosed position inside the CFRP-constructed Life module (mounted above the Drive module).
The sporting character of the BMW i8 Concept continues into the interior. Boasting a driver-focused environment unmatched by any BMW Group vehicle before it, the BMW i8 Concept immerses the driver fully in the unique driving experience. The purpose-built driver's position is geared squarely towards the person at the wheel and gives optimum access to all information and controls. The three-dimensional displays are crystal clear and flash up the relevant information for the driving situation at hand. The interior as a whole is defined by the functionality of a classical BMW sports car and majors on lightness and ease of use. The BMW i8 Concept is the sports car for a new generation ? pure, emotional and sustainable.
