Electric living with a BMW i3

Rarely in the 27-plus years I've been testing and writing about cars has any vehicle changed this much from my initial impression until I was later able to spend more time in one. Nearly two years ago, I got a brief test drive of the then-new BMW i3 EV on a selection of both flat and hilly, curvy roads west of Los Angeles the day before LA Auto Show press days. My impressions at the time were mixed: polarizing exterior and interior designs but roomy, easily accessible rear cabin; great twisty road handling but somewhat brittle rough-road ride; good performance but annoyingly strong (always on) regenerative braking. And there was no opportunity to test one with the optional range-extender (which BMW calls a "REx") engine. So I wanted an extended experience in a REx-equipped i3, and recently got one. And, I'm here to report that, driving it for a week like I owned it, the quirky i3 soon won me over. The quirky i3 soon won me over. The $42,400 BMW EV's unique, lightweight "LifeDrive" architecture features a Carbon Fiber Reinforced Plastic (CFRP) passenger cell on an all-aluminum chassis. Powered by a 22-kWh lithium-ion battery pack, its 170-hp AC synchronous motor spins out a healthy 184-pound-feet of torque through a single-speed transmission and offers three drive modes: Comfort, Eco Pro (which BMW says adds roughly 12 percent of range) and Eco Pro+ (another 12 percent). The optional rear-mounted 647 cc (0.65-liter) in-line 2-cylinder REx engine drives an electric generator, never the wheels. It increases the sticker price to $46,250 and curb weight from 2,860 pounds to 3,130 lb., and that 270-lb. weight penalty reduces its electric-only range from 81 to 72 miles and EPA-rated combined (gas-equivalent) fuel economy from 124 to 117 MPGe, and slows its 0-60-mph acceleration from 7.0 to 7.8 sec. But it nearly doubles the i3's official EPA-rated total range from an EV-only 81 miles to an EV-plus-gasoline 150 miles. The i3 arrived (from roughly 90 miles away) with its battery depleted but an indicated 75 miles of gas-powered range remaining. Wanting to experience it REx-only at first, I drove it on a 9.6-mile local trip and found little difference in sound or performance from what I recalled from that California battery-only test drive. When I returned home, however, the indicated gas range was just 55 miles, so I had used 20 miles of projected range in less than 10 local miles. My initial impressions were good, with a few quibbles.

BMW i8 to go full-electric after facelift

According to Autocar, BMW has plans to turn the i8 sports car from a hybrid to a fully electric vehicle. The carbon fiber structure would be modified with a wider center tunnel to house a sizable battery. Despite this, there would be no weight gain to the i8; the current version weighs in at 3,274 lbs. The electric prototype would have three BMW-developed brushless electric motors, two of them powering the rear wheels and one of them taking care of the front wheels. As the 1.5-liter gasoline engine would be shelved, there would be ample space for the two rear-mounted motors. Currently, the i8 produces 357 horsepower all told, but the electric motors in the prototype are said to produce up to 268 horsepower – each. The electric prototype is to be based on the architecture of a hydrogen prototype, which manages 242 horsepower in total. The information relayed on to Autocar comes from a source close to BMW's development boss, Klaus Frohlich. The facelifted version of the i8 should arrive next year, with awaited improvements like a new 26Ah lithium ion battery – 6Ah up from the current version. There is also talk of a Qualcomm inductive charging system, and its 7.2kWh operating power is doubled from the current 3.6kWh plug-in setup. If the rumormill is to be believed, engine output in the facelifted version would be up ten percent, resulting in 390 horsepower.

BMW M4 Concept bows, takes handoff from M3 Coupe

Remember how, when the first BMW M4 Concept images leaked earlier today, we told you the official information would be coming later this evening? Well, scratch that. The whole kit and caboodle is now online, meaning all the official details are below, as well as a full gallery of high-res images above.
The replacement for the M3 Coupe, the Concept M4 Coupe shares a number of styling similarities with its dearly departed forbearer. To us, it's kind of like a mishmash of greatest hits from the new 4 Series and the old M3. The 4 Series headlights have grown on us, and the side grilles, which are part of BMW's Air Curtain and Air Breather system, are functional.
The power dome in the hood is smaller than on the M3, but is of a similar shape, while the rear diffuser and exhaust treatment look like they're lifted straight from the old car, aside from being finished in carbon fiber. Speaking of which, the carbon fiber roof sports a new touch, a cool BMW M tri-color that runs the length of the roof on the driver's side. The 20-inch M alloy wheels come in a twin five-spoke design, which has sort of become a calling card of BMW's M cars in recent years. Hiding behind those meaty wheels are M's carbon-ceramic brakes.
