TheBMW i3 is the world’s first
premium car designed from the ground up to be powered by an electric
drive system. The result is hallmark BMW driving pleasure in
undiluted form, delivered with zero emissions and an engaging
intensity unmatched by any electrically powered vehicle.
The familiar sense of driving pleasure
embodied by the BMW i3 is the result of a rigorously implemented
overall concept, part of which has involved creating the optimum
balance of weight, performance and range for urban mobility. The key
elements here are the LifeDrive architecture and BMW eDrive
technology. The use of lightweight CFRP for the passenger cell
cancels out the extra weight contributed by the lithium-ion battery,
while the low, central positioning of the battery pack enhances the
car’s agility thanks to perfectly balanced 50 : 50 weight
distribution. Additionally, the electric motor mounted in close
proximity to the driven rear axle offers unique performance
characteristics for this type of drive system as well as providing
unbeatable traction. The driving characteristics of the BMW i3 are
dominated by its manoeuvrability – a direct response to the demands
of city driving. The instantaneous power delivery of the electric
motor, allied to the car’s stiff suspension set-up, precise
steering and impressively small turning circle (9.86 metres),
produces a typically BMW take on electric mobility
The electric motor generates output of
125 kW/170 hp and peak torque of 250 Newton metres (184 lb-ft), which
is on tap from the word go. The motor weighs just 50 kilograms and
boasts power density and responsiveness unprecedented in the world of
electric mobility. The specific construction of the hybrid
synchronous electric motor, developed exclusively for the BMW i3,
maintains a linear flow of power into
the higher reaches of the rev range. The BMW i3 sprints from 0 to 60
km/h (37 mph) in a mere 3.7 seconds and 0 to 100 km/h (62 mph) in 7.2
seconds.
The single-pedal control concept in the
BMW i3 – configured by the BMW Group’s drive system development
engineers – also contributes to the engaging driving experience.
Recuperation mode is activated the moment the driver takes his foot
off the accelerator. The electric motor switches from drive to
generator mode, feeding power into the lithium-ion battery. At the
same time, it generates a precisely controllable braking effect. This
recuperation is speed-sensitive, which means the car “coasts”
with maximum efficiency at high speeds and generates a strong braking
effect at low speeds.
The lithium-ion battery enables the BMW
i3 to achieve a range of 130 to 160 kilometres (81 – 99 miles) in
everyday driving. This rises by around 20 kilometres (12 miles) in
ECO PRO mode and by the same distance again in ECO PRO+ mode. If
desired, the BMW i3 is also available with a rangeextender engine,
which maintains the charge of the lithium-ion battery at a constant
level while on the move as soon as it dips below a specified value.
This role is performed by a 650cc
two-cylinder petrol engine developing 25 kW/34 hp and mounted
immediately adjacent to the electric motor above the rear axle. The
range extender increases the car’s maximum range in dayto-day
driving to around 300 kilometres (approx. 180 miles).
The world’s first fully networked electrically powered car
The BMW i3 is the world’s first fully
networked electrically powered car. No other model boasts such
far-reaching exchange of information between the vehicle, its driver
and the outside world. A SIM card fitted as standard in the BMW i3 is
the key that unlocks the BMW ConnectedDrive services – in their
recalibrated 2013 guise – available to the new electric model. For
example, it
introduces navigation services
specially developed to enhance electric mobility alongside familiar
features including the Concierge Services information facility and
the Intelligent Emergency Call function. Moreover, drivers can use
the BMW i Remote app to share information with their car at any time
using their smartphone. The pedestrian navigation function guides the
driver from parking place to final destination and back, while BMW
ConnectedDrive also offers unique intermodal route guidance as a
world first, which incorporates local public transport connections
into journey planning. The aim of this intelligent networking is to
enable maximum driving pleasure in a car emitting zero local
emissions.
The BMW ConnectedDrive services
specifically designed for BMW i focus on the areas of navigation and
energy management. The Range Assistant is engaged both for route
planning and during journeys already under way. If the destination
programmed into the navigation system is beyond the car’s range,
the system suggests switching to ECO PRO or ECO PRO+ mode and
calculates a more efficient route. If the driver needs to charge the
battery at a public charging station, a list of available stations in
the area is displayed. The navigation system of the BMW i3 also comes
with a dynamic range display, which supplies drivers with
exceptionally precise, up-to-date and reliable information on whether
there is sufficient charge to reach their destination and, if so, how
much power will remain at the end of the journey. All the factors
affecting range are considered in the calculation process, which is
carried out on a BMW server and sent to the navigation system via the
SIM card installed in the car. The range readout, presented in the
form of a spidergram on the navigation map in the central information
display, is extremely clear.
The link-up between driver and car also
enters a new dimension in the BMW i3. The BMW ConnectedDrive Remote
app for BMW i enables smartphone access to useful vehicle data for
journey planning. If the BMW i3 is hooked up to a charging station or
the BMW i Wallbox, the supply of energy can be controlled via
smartphone, while the air conditioning and heating function for the
high-voltage battery pack can also be activated remotely. In
addition, customers can use their smartphone to send destinations to
their car’s navigation system. The app also shows the driver
charging stations (both available and in use) and can establish if
the car has sufficient power remaining to reach them. The car’s
range limit display on the smartphone screen replicates that provided
by the car’s navigation system.
The BMW i3 is also available with an
array of other innovative BMW ConnectedDrive driver assistance
systems developed specifically to enhance convenience and safety in
urban conditions. These include Driving Assistant Plus, Parking
Assistant, a rear view camera and Speed Limit Info.
360° ELECTRIC provides an all-encompassing energy supply and mobility solution
The aim in determining the range of the
BMW i3 was to ensure that customers could cover their typical energy
needs by charging the car twice or three times per week. The studies
carried out as part of project i – involving more than 1,000
participants and conducted over some 20 million kilometres (approx.
12.5 million miles) – revealed that the average daily distance
covered was around 45 kilometres (28 miles). Customers can charge
their cars using either the wallbox supplied by BMW i or a
conventional domestic power socket.
BMW i offers an extensive range of
products and services in its 360° ELECTRIC package designed to meet
all individual customer needs for energy supply and journey planning.
The spectrum of services ranges from the installation of the BMW i
Wallbox in the customer’s garage and special
renewable energy supply offers, to the
charging card for user-friendly access to the public charging
infrastructure and additional assistance services from BMW
ConnectedDrive. If the BMW i3 concept fails to meet mobility
requirements in a specific situation, 360° ELECTRIC provides
flexible mobility solutions including alternative vehicles from the
BMW and DriveNow ranges.
