The BMW i3 is the German brand's first-ever all-electric car, packed with cutting-edge materials and technology, and offering an innovative solution to range anxiety: an optional two-cylinder motorcycle engine that provides electricity to the battery to keep the car on the road once the battery is depleted.
The i3 is a BMW like no other. Launched in 2014, the little city car is so different from BMW's carefully-honed traditional lineup of sporty sedans and crossovers that it forms the first entry in what will become a range of special "BMW i" sub-brand vehicles.
The shape of the BMW i3 is unlike that of anything currently within the BMW or MINI fold, but that's because it's been conceived from the start as a dedicated electric car,
The i3 is designed and styled for urban environments. The tall hatchback has plenty of glass all around, including on the hatch, to provide great visibility and make parking easy in tightly packed cities. The doors are hinged at the rear to keep it short and provide a coupe-like look. The tall and narrow tires measure 155/70R19 and are of the low-rolling-resistance variety to improve mileage.
The 22-kilowatt-hour lithium-ion battery that powers the i3's rear-mounted electric motor is sandwiched into the car's floor. The body is made of carbon-fiber reinforced plastic (CFRP), so strong that there are no pillars required between the front and rear doors on each side. And like the iconic Toyota Prius and the more recent Nissan Leaf, the BMW i3 is instantly identifiable--with looks that provoke strong reactions, one way or another.
The i3 can trace its roots to BMW's MegaCity concept car. The architecture that concept spawned is called LifeDrive—it's a passenger (Life) module set atop a powertrain (Drive) module, for a modern twist on the old body-on-frame idea. In a first for a mass-produced vehicle, the passenger cell is produced from carbon-fiber-reinforced plastic, while the rolling chassis is made of aluminum.
The i3 is primarily an electric car—with a robust 170-hp rear-mounted electric motor system providing somewhere between 80 and 100 miles of driving range. But separately there’s the option for a range-extender—a 650-cc gasoline twin-cylinder engine, making 34 hp.
Although modest, the system's output is enough to move the i3 in a sporting way; BMW claims a 0–60-mph time of 7.2 seconds, and the little city car can top out at 93 mph. The rear-drive layout and near-50/50 front/rear weight distribution help it to outdo the dynamics of other small electric cars, although the handling is somewhat affected by the tall body and boosted electric steering. The weight-saving measures also pay dividends here, as well as with energy consumption.
In the BMW i3, the range extender only functions to provide electricity, not supplemental tractive power, like in the Chevy Volt. With its tiny 2.4-gallon fuel tank and an estimated 33-42 mpg, it should about double the effective range—as well as curb any range anxiety. The i3 will charge up to full in about three hours at 220 volts, or get to a full charge in 30 minutes using an (upcoming) SAE DC fast-charger.
As you might guess from the outside, the i3 has a very upright cabin layout that helps make the most of available space. Cabin upholstery includes recycled materials—even the wood has been sustainably sourced—and with the tall roof there looks like enough space for adults in back.
Three different trim levels of the i3 will be offered: Mega World, Giga World, and Tera World. Navigation, ConnectedDrive, LED headlights and running lamps, an alarm system, and 7.4-kW charger are included on all levels. The Giga World adds a sunroof, contrast stitching, and satellite radio, while the Tera gets special trims, a full leather interior, and unique wheels. As with BMW’s more conventional offerings, there will be plenty of chances to upgrade, with high-tech possibilities like
Pricing for the U.S. starts at $42,275, and it went on sale in May 2014. Thus far, early sales are split about 60:40 between the range-extended and battery-electric versions.
At the 2015 Consumer Electronics Show, BMW unveiled a concept i3 that can park itself without a driver in the vehicle, stowing and retrieving itself in parking garages. The company also showed an i3 equipped with an advanced laser sensor array for safety, as well as a smartwatch app that can control some vehicle functions. With the exception of the latter, which is now available, no timetable has been set for rollout of these features to the i3 or any other BMWs.
