- Zero-emission, 80-100 mile EV range with sporty appeal launches new BMW i sub-brand
- MSRP of $41,350-$45,200 (three trim levels)
- Available Q2 of 2014 in USA
- Carbon Reinforced Plastic design greatly enhances efficiency
BMW has announced the specs, features, pricing and release date range for the all-new i3
all-electric vehicle. From concept and 2011 i sub-brand news to today's worldwide
debut, the four-door BMW i3 focuses on snappy all-electric urban mobility and safety. It
will be available in America the second quarter of 2014 for a base MSRP of $41,350 -
three trim and tech packages available.
Powered by a 110 lb, 170hp, 184 lb-ft hybrid-synchronous electric motor, BMW claims a
real-world EV range of 80-100 miles - a Motor Trend i3 First Drive claimed a 0-60mph
time of around 7 seconds. The i3 utilizes the BMW eDrive rear-wheel drive powertrain
found on the BMW ActiveE. A single-speed transmission delivers uninterrupted zero-emission power to the wheels. Performance and range hinge around what BMW is calling
its LifeDrive architecture concept, which comprises of a "Life Module" or passenger
cabin and "Drive Module."
The i3 has footprint the size of the 1 Series. It boasts a small turning circle of 32.2ft due to narrow 155/70/19 sized tires on 19-inch light-alloy wheels, which are claimed to have a contact patch of a more conventional 16-inch tire. 50-50 weight distribution and electric power steering also help create a vehicle that is extremely nimble in tight city situations.
Iconic kidney grilles mark the front end along with Aerodynamic Air Curtains that
minimize drag. A rear diffuser, which is the lowest part of the car, also aids in aero. U-
shaped LED headlights front and rear highlight a fresh take on BMW light design. A
large rear window then increases driver visibility.
The all-aluminum Drive Module consists of a 22-kWh, 450 lb lithium-ion battery,
electric drivetrain, MacPherson strut and 5-link rear suspension system, and structural
components. The battery is mounted low and to the rear, close to the drive wheels to
For those interested in further driving range, an optional rear-mounted 650cc, 34hp, two-cylinder, gasoline-powered Range Extender generator is available, which roughly
doubles the vehicle's range. At a predetermined battery level, the Range Extender turns
on and maintains the battery's current state of charge. The Range Extender never directly
drives the vehicle's wheels. It adds roughly 330 lb to the vehicle's curb weight and has a
fuel capacity of 2.4 gallons.
The i3 features Brake Energy Regeneration, which aids in EV range by converting kinetic
energy into electricity. When the driver lifts off the pedal at higher speeds, the
decelerating motor acts as a generator that routes electricity into the battery. At lower
speeds the regeneration feature is disabled to allow the car to coast and generate a strong braking effect.
On the acceleration end, the right pedal has a "neutral" position to preserve energy and
increase range as well. This means that when the driver eases off the accelerator, the
electric motor uses zero torque control to separate from the drivetrain and utilizes only the
available kinetic energy for propulsion. In this mode, the BMW i3 cruises using virtually
no energy at all.
A leading reason for the claimed 2,700-pound i3's efficiency is its Carbon Reinforced
Plastic (CFRP) Life Module passenger cabin design - an industry first for mass produced
automotive passenger cells. CFRP is equally as strong as steel at 50 percent the weight.
It is also 30 percent lighter than aluminum. The lightweight passenger cabin, which features the interior space of the BMW 3 Series, lowers the center of gravity for improved handling characteristics.
Emphasizing safety is CFRP's ability to absorb impact energy. Crash-active aluminum
structures in the front and rear reinforce the exterior too. The low battery position also
was purposely placed away from common impact areas. To minimize the threat of battery
fire, in the event of a crash, it is disconnected from the system and discharged when the
passenger restraint system is triggered. This prevents the possibility of a short circuit,
which could cause a fire. After an accident, driver and passengers also can depend on an
automatic Intelligent Emergency Call (eCall), which quickly sends location, number of
front-seat occupants and crash data to the BMW ConnectedDrive Call Center who then
routes the information to a 911 dispatch center.
While head turning looks may not be the main selling point, BMW made aspects of the
car more inviting with a focus on technology. For instance, the navigation unit not only
tracks detailed live traffic conditions but also driving style for better prediction of route in relation to remaining battery life. An embedded SIM card unlocks BMW ConnectedDrive services that can search nearby charging stations, connect to a 24/7 Concierge Service, alert authorities in the event of an accident and Driving Assistant Plus Services.
The optional Driver Assistant Plus features Collision Warning (audio/visual alerts) with a
brake priming function, which is activated at speeds up to an estimated 35mph. It can
respond to both moving and parked vehicles, and pedestrians by braking the vehicle
without driver input. The Parking Assistant makes parallel parking fully automated.
Traffic Jam Assistant allows the i3 to delegate the tasks of pulling away, braking and
steering to keep the vehicle in lane. A Speed Limit Info system is also available. A BMW
i Remote app then allows users to link their phone to their car.
Complementing the interior technology are driving controls that are ergonomically placed for easy driver access. The instrument panel spans across the entire interior. The freestanding steering column features the instrument cluster, start/stop button and gear
shift selector. Motor Trend had this to say about the interior of the i3:
"The interior isn't the usual dark, brooding, uber-serious German hunting cabin, but a
place of bright, playful fun. Atop its wave-shaped dash are twin, freestanding displays.
They essentially perform the same duties as BMW's current two dash-imbedded ones, but
perch airily like a couple Kindle Fires on stands. When you open the doors, portions of its naked carbon-fiber passenger cocoon are risquely displayed. This enclosure is one of the i3 bright spots."
The i3 will come in three different trim and tech packages, which BMW refers to as
- "Mega World" is the base model offeirng: 19in extra-efficient forged aluminum
wheels, BMW navigation, BMW ConnectedDrive with eCall, BMW i Remote,
