The BMW i3

After years of prototypes and testing, BMW has pulled the silken cloth off the i3, its first all-electric car and the first member of its "i" sub-brand of green cars. The global premiere was a triple-city affair, taking place simultaneously in Beijing, London and New York. The US$42,000 electric hatchback employs some of BMW's most advanced technologies to date.

Electric done BMW-Style

In research that was conducted during its Project i, which involved 1,000 participants and more than 12.5 million driven miles, BMW found that the average daily driving distance was around 30 miles (48 km). When viewed through that prism, the i3's 80 to 100 miles (129 to 161 km) of range looks more than ample. BMW says that ECO MODE can add an extra 12 percent on top of that.

For those that don't believe the range is ample, BMW offers an interesting option. Unlike other automakers, who have kept models strictly electric or strictly hybrid, BMW is hedging its bets with the i3. In addition to the all-electric version, buyers can choose to equip the i3 with a 34-hp 650cc range-extending two-cylinder engine, essentially turning the car into a Volt-like series hybrid. That engine will not power the wheels but will serve strictly as a back-up power reserve, adding range and versatility.

BMW says that the range extender, which has a fuel capacity of 2.4 gal, roughly doubles the car's range, which still falls well short of a traditional gasoline car. More important than outright range, however, is the fact that, with the range extender, drivers can refuel at gas stations rather than having to find an electrical charge station. Gas stations are far more readily available than charge stations and also provide quicker refueling.

The i3's basic powertrain specs remain much the same as when BMW introduced the last i3 concept at the LA Auto Show last year. The 170-hp electric motor, which twists out up to 184 lb-ft of torque, receives its power from a 22-kWh, liquid-cooled lithium-ion battery. Thanks to the optional SAE DC Combo Fast Charging hardware, that battery can fill to 100 percent in about 30 minutes. The 220-volt Level 2 J1772 charger, meanwhile, takes care of business in about 3 hours. The motor works in concert with a single-speed transmission to send power to the rear wheels.

The i3 can't compete with the upcoming i8 when it comes to speed, but it will offer drivers ample pep for daily commuting. It can accelerate to 30 mph (48 km/h) in 3.5 seconds and 60 mph (96.5 km/h) in about double that time. The car's top speed is 93 mph (150 km/h), which is electronically limited to conserve electricity.

The i3 uses regenerative braking to help keep the battery running as long as possible. The regeneration is speed sensitive, employing braking at lower speeds and coasting at higher speeds. As BMW tells it: "Rather than switching straight to energy regeneration when the driver eases off the accelerator, the electric motor uses zero torque control to separate from the drivetrain and deploy only the available kinetic energy for propulsion. In this mode, the BMW i3 cruises using virtually no energy at all."

Lightweight materials and compact design

The powertrain may be the technological highlight of any EV, but electric cars also tend to have a lot of other technologies at work, pulling the most range and efficiency possible out of that powertrain. The i3 sets a new standard in this regard. According to BMW it uses the first mass-produced carbon fiber-reinforced plastic (CFRP) passenger cell build in the auto industry. BMW has committed to bringing carbon fiber, more common in supercars like the Lamborghini Aventador, into the mainstream, and the i3 is one of the first models that makes good on the promise.

The CFRP is used in the construction of what BMW terms the "Life Module" (i.e. the cabin area), helping to slim the i3 down to roughly 2,700 lb. That weight is distributed at a near-perfect 50:50 ratio. The "Drive Module" (i.e. chassis) is made of all aluminum, and other lightweight materials like a magnesium instrument panel cross-member add to the weight savings.

In addition to its light weight, BMW says that the CFRP Life Module, combined with crash-activated front and rear aluminum structures, offers ample safety and protection. The company coordinated with international crash test agencies to thoroughly test the integrity of the design and reports that CFRP's rigidity and high impact absorption allow it to maintain form and protect occupants well. The battery is positioned in the underbody of the car, where it is least likely to be affected by the impact of a crash.

The debut i3 is in the form of the four-door, as opposed to the Concept Coupe from LA. When compared to the original i3 concept, it loses the extreme glass doors, but maintains the expanded rear side window of the Concept Coupe. The rear-hinged rear coach doors create an open, B pillar-less entry into the car. Other exterior design features of interest include U-shaped LED head and tail lamps, contrasting black surfaces, a large rear windshield, and aerodynamic air curtains.

BMW designed the i3 as a city car through and through, using short front and rear overhangs to improve maneuvering in tight driving and parking spaces. The car has a turning radius of 32.3 feet (9.8 m), helping it to remain nimble around cramped city centers. Thanks to the elimination of the typical transmission tunnel, the open interior offers a "Slide Through Experience," allowing the driver to easily slide over and jump out the passenger door to avoid exiting onto a busy street, or perhaps when the space is too tight to open the driver-side door.

Futuristic interior

While naming the cabin the "Life Module" seems a little dramatic, the i3's interior does separate itself from the average car. In addition to the Slide Through Experience, the loss of the transmission tunnel increases space and creates a more open feel, which is further promoted with front and rear bench seats. A clean, functional dashboard keeps the driver focused on his mission of navigating from point A to B. The freestanding steering column houses all of the controls he'll need to push forward, including the instrument cluster, start/stop button and gear shift selector.

BMW reminds driver and passengers they're in the most eco-friendly of rides using a portfolio of available sustainable materials it calls "Next Premium." The sustainable eucalyptus wood trim showed in the concept stages carries over to production, as does the olive leaf-tanned leather. Parts of the instrument panel and door panels are made from natural fibers procured from southern Asia’s Kenaf plant.

Navigation and infotainment is handled by a SIM card-powered BMW ConnectedDrive system tailored specifically to electric driving. BMW i Navigation delivers a real-world driving range estimate and mapping visualization, taking factors like elevation and distance into account. The system also provides information about nearby charging stations.

On the road, the driver has access to a ConnectedDrive agent at all times of the day. The agent can provide information about things like charging stations and points of interest. BMW's Intelligent eCall provides emergency assistance, sending information about the location, number of front-seat occupants, and crash severity to the BMW ConnectedDrive Call Center, which notifies the appropriate 911 dispatch.

The i3 also leverages the latest mobile technology to enhance functionality both in and out of the car. An Apple cable connects iPhone owners with apps and phone features. The BMW i Remote smartphone app offers functions like battery monitoring, car location, and door locking and unlocking.

Pricing and availability

The BMW i3 will launch in Europe in November and in the United States in the second quarter of 2014. It will be available in three trim levels – Mega World, Giga World and Tera World – starting at US$41,350, before any federal or state tax credits or BMW's destination and handling fee. All three trim levels include the ConnectedDrive system, Intelligent eCall, i Remote app, trim-specific 19-inch wheels, a 7.4 kW onboard charger and LED headlights. The main differences are in interior materials and equipment. The Range Extender i3 model will start at $45,200, before destination and handling fee or tax incentives. Product page: BMW i3

While the volt was promoted as a serial hybrid before it's introduction, unfortunately it wasn't to be. They claimed some vague marketing reason and actually shipped a parallel hybrid. More info at: http://www.autoguide.com/auto-news/2010/10/gm-admits-chevy-volts-gasoline-engine-can-power-the-wheels-so-is-it-still-special.html And: http://www.popularmechanics.com/cars/alternative-fuel/cells/chevy-volt-hybrid-drive-system Seems like the worst of both worlds. Two transmissions (electric and gas), extra weight, and extra cost. The I3 is the first true series hybrid that I know of.

Can the range extender be removed from the car when not needed... Or is it hard mounted into the vehicle.. (making it removable would be a great Idea...) Also. stop saying that the Volt is a series hybrid... It is a parallel hybrid variant... Noting that parallel hybrids are able to achieve higher efficiencies under some operating regimes, so it isn't negative to market it as such... (People may feel a little ripped off when they find out that their great new electric car, still has a mechanical link from the engine to the wheels...) Obviously this vehicle has no such connection, and the range extender appears to be purely a generator. Keep the concepts coming. Great to see. (Quote for the die hards: "In effect, the gas engine supplies power directly to the transmission, which is just like a parallel hybrid." "...caused some consternation because over the Volt's development GM has stated that the gas engine never directly powers the car. While that's not entirely true,..." Popular Mechanics

"It's time we make an electric car. I know, let's make it look terrible!" -every designer from an established car company I thought BMW was smarter than that but they're really going ahead with these ugly things.

Let me tell you what I and most other consumers want for an electrical car. 4 door sedan with gorgeous looks inside and out. Range of about 250-300 miles and a price no more than 30K. Till this is done electric cars will always be an after thought when it comes to buying a car. Having said that my hats off to Tesla as they have done an amazing job so far. They will come up with the car I am wishing for with in the next 3-5 years of not in 2.

Gotta hate these useless press release photos car makers give to news outlets. Geez, BMW! Show me the trunk! What's under the hood in the front? Come on, lederhosen!

Show me a 2 seater conv. that is sporty & fun to drive. I suggest that BMW consider a 2 seater convertible that would be a fun commuter, think electric Lotus 7-ish that old school sports car drivers would call "spidery" which would be hugely popular, instead of just another puffed up (mini-ish) blob-mobile with two big nostrils, a set of flashy rims and tall tires! For similar money you can buy a electric classic Bug from Zelectricmotors http://www.zelectricmotors.com/about that may or may not be a convertible but we know they are fun to drive, especially around town...

It is a nice idea and design to have the electric range up to 100 miles. The range is an plus over other e-cars. To overcome the anxiety of the range, in each and every gas stations the car manufactures should have the fast charging stations and all cars must have universal connectors rather than having its own proprietary chargers. However no car is near to Chevy Volt in design and technology. They set the standards in electric cars. But failed to market it. And also bad media gave negative image about the car. Many wrote he reports on Volt without driving the car. Just for your information I was proud owner of Chevy Volt. Tesla Model S is a super car, but it is far beyond reach to mass. Only few can buy it not to save the money on gas> The person spends 100 grand it does not matter to him to spend few dollars on gas whatever the price may be. The price of e car should be in the range of $30,000 which is affordable to many.

Why can BMW make the i3 a hip car - or at least not so ugly? The new i3 is almost as ugly as the Pontiac Aztek. It seems they think electric car owners do not care about the car atheistic look.

With performance figures nearly identical to the Mini Cooper S, and 50/50 weight distribution it sounds like a fun track day car. I'm also guessing that the potential torque available from the electric motor just might be electronically limited as well for the sake of range.
Don Duncan
Closer to a practical EV, but not close enough (no cigar). Too pricey. This is not a fully functional car at 100 mile range, 200 if you want to part with another $4000. And what about the battery life? When it goes how much to replace? The range is fine except for my once a year trip. Then I need 400+. Why couldn't they have made the gas tank 7-10 gals? Or extend the range by lower weight (2 seater) and lower drag. Curtains? How about sealed wheel wells and undercarriage? And slicker body?
