BMW is taking the step in the development of plug-in with its i3 electric car due out at the end of 2013. The i3 be a city car made of carbon that BMW plans to sell in big around the world.

Last BMW announced the i3 would come an optional gasoline-powered range internal combustion engine runs a generator to provide range once the batteries are

The Chevrolet Volt and the Fisker have similar set-ups. use versions of General Motors’s four-cylinder engine. The Volt an 84-hp, 1.4-liter version, the Karma uses a 260-hp, 2.0-liter version.

Intended as a car, the i3 will use a much gas engine.

This follows in line with what Dr. Frank—a mechanical engineering at the University of California who is considered the of the plug-in hybrid—had in mind ago. (A plug-in hybrid is name for an extended-range electric His idea included reducing the and capability of the gas powertrain to make up for the weight of the batteries.

At a BMW-hosted event in New York yesterday, we had an opportunity to meet key people on the i3 development team, to more about this car and the technology within it.

When whether the i3 would use an engine BMW’s car or motorcycle parts Chief Engineer Ulli initially demurred. But his eyes lit up it was suggested that a motorcycle might be a perfect fit for such a At the same event, BMW announced its upcoming i8 plug-in hybrid will use a small three-cylinder boasting 220 hp, to drive the rear

BMW has claimed the i8, which will more than $130,000, have acceleration times of than five seconds 0-60 mph. Reports noted that the electric on the front axle is good for 260 kW, or 349 hp, we’re not sure how much of it will use. Presumably of its power will come the electrically-driven front wheels.

In cars, BMW has said, reducing the weight has an exponential effect on weight and cost in the battery and boosting performance and range reducing charging times). why the i3 is made of carbon fiber and

The i3 will use an all-aluminum chassis will house all the drivetrain including flat-format prismatic batteries (made by Bosch and and assembled by BMW), and an electric on the rear axle. Kranz the carbon fiber that on the chassis will offset the weight of the batteries, saving 500 pounds. A further benefit, smaller batteries will charging time.

The batteries will be liquid which will allow to pre-heat and pre-cool the cabin, and minimize the effect of cold on range.

Kranz also that the car will be 100-percent That’s right, 100 percent the batteries. To aid that goal, the i3 make extensive use of naturally fibers in the interior, including the and seats.

BMW believes that will be seen as a luxury when the car goes on sale.

The i3’s drivetrain will be in BMW’s upcoming Active-E car. a 1 Series coupe to electric power. Unlike previous electric car, the the Active-E won’t have its seat consumed by batteries. The new flat-format battery pack and its system are smaller than the battery pack in the Mini-E.


says this is the drivetrain for the i3.

The i3 will roll out in major around the world, including the markets. It will include two new in the United States: Boston and San Other U.S. cities Los Angeles, San Francisco, Sacramento, and New (including New Jersey and Connecticut

Rich Steinberg, manager of electric-car programs in the United says the company is focusing on that have planned for vehicle rollouts and have public charging infrastructure in to ease electric-car buyers’ anxiety.” Of course, that not be an issue for owners of the version the optional range-extending gasoline He says he sees public as eliminating a psychological barrier, though BMW’s analysis most electric-car drivers charge at home.

BMW expects that between 5 and 15 percent of cars will in for some or all of their power by

The i3 will fit in with other cars on the market such as the Volt and the Nissan Leaf. the Leaf, the i3 is targeting about a range without the range-extending gas Our just-released test of the Leaf has that its claimed 100-mile is about 75 miles in the real (and about 90 miles on an day). Our tests show cars are very inexpensive to

If BMW’s weight saving can bring down the required and cost of the batteries, that strengthen the case for electric and hybrid cars.
