It has been three since BMW announced its new i lineup, a of so-called megacity vehicles with the compact i3 city car and i8 sports car .

The idea behind i is to motoring to efficiencies not yet seen, a combination of state-of-the-art carbon-fiber and zero-emission electric propulsion. as BMW chairman Norbert Reithofer back in 2010, i cars have enough financial to make it possible for anyone the simple need to get from A to B to get in on the

i3 — Driving Goes High-Tech

We at BMW’s test center in ground zero of the European industry’s winter test The i3 exits the workshop first. primarily for city use, 4.7 inches longer and 5.2 inches than a Mini Cooper.

It also boasts 7.1 cubic of luggage space behind the seats, 1.4 cubic feet than its British sibling.

North American sales in 2014, there will be two of the i3, both running an electric similar to the 1-series ActiveE’s: A electric motor providing 168 hp and 184 of torque to the rear wheels via a gear transmission.

A lithium-ion mounted in the flat floor energy. It can be charged by plugging it in and by kinetic electricity produced on the BMW says range is 139 miles on the test procedure, or between 80 and 100 real world.

Alongside the EV, BMW will a range-extender option with a two-cylinder gas engine borrowed its C650 GT step-through motorcycle. It is to start up when the battery drops to a specified point. The acts only as a generator to electricity, extending the i3 range to 186 miles.

Pricing hasn’t announced, and likely won’t be the i3’s public premiere at fall’s Frankfurt motor but our guess is somewhere around BMW thinks most i3s will be as part of its Drive Now initiative, participants swap their i3 for a conventional BMW when required.

Our chauffeur is Mueller, BMW i drivetrain development He says the i3 is much like the ActiveE in overall character, a heavily sprung throttle, acceleration and aggressive recuperation aimed at recovering as much energy as possible. [This] set our cars apart from the competition, he suggests. When he off the throttle, the electric motor as a generator, providing enough power; brakes are rarely

It’s so aggressive, BMW has programmed the LED lights to illuminate when you the throttle.

The prototype we’re in feels solid, even if is the odd rattle from the disguise-covered of the interior. What really our attention is its overall agility in trying conditions with narrow tires, excellent Watching Mueller thread the down slippery lanes, low-traction hills and around lots, the car appears to possess all the required to make it suited to use, including a good circle.

We won’t drive production until later this For now, we can say the i3 will not only good maneuverability, but should be entertaining.

As with the i3, the i8 is based a carbon-fiber structure — it weigh 3,263 pounds in Unlike the i3, the i8 uses a plug-in hybrid system for performance. In severe weather, it would in electric mode.

A turbocharged three-cylinder direct-injection gas engine the car. It’s the same we tested last year in a prototype and will be in the next-generation The first of those will bow at year’s Los Angeles show.

transversely behind the roomy the aluminum-block three-cylinder develops 220 hp and 221 of torque, channeled to the rear via a six-speed automatic gearbox. boisterous, emitting a distinctive hum that gets deeper, and more prominent as engine rise.

The gasoline engine is not the propulsion source, of course: An motor shared with the i3 up front, sending an additional 130 hp and 184 to the front wheels. There’s a second smaller electric mounted at the rear next to the engine, producing 5 hp and 3 lb-ft. it can provide drive to the rear its primary purpose is as an alternator generator, depending on which mode is chosen: eco-pro, or sport.

BMW is most proud of the excellent fuel economy. official yet, but the company at a combined 87.1-mpg (U.S.) — a figure that away every production BMW

Rushing along snow-covered we notice an E-mode button on the tunnel. Van As punches it and the drive goes from gas-electric to all — a lithium-ion battery mounted in the center tunnel the power. It is a neat trick, silent journeys of up to 22 miles on alone.

Leaving the BMW test and heading out on public roads, the interplay between the three sources is noteworthy: the result, van As of countless hours spent the i8’s electronic algorithms.

It’s impressive the way the i8’s drivetrain switches from (all three power used) to pure electric (just one power source) at the of a button. In hybrid mode, all wheels are driven. In electric, the car is drive.

It sounds remarkably complex, but never know it, such is the interplay.

Further impressions? it’s billed as a sports the i8’s ride is excellent, as as the upcoming 4-series coupe. Van As the company is aware some will use the i8 every day.
