We did the bulk of our 67-mile trip from Montclair to Chester, New Jersey, and back again in EcoPro, reverting to Normal for several acceleration and handling tests.
That trip, including a number of hilly roads and a few brief spurts of acceleration, used 88 percent of the battery capacity, for a real-world usage of 2.7 miles/kWh--not the best efficiency we've experienced.
Moloughney said he's eager to test out the car's range in warmer weather, and he suspects that with careful driving in spring temperatures, he'll be able to get more than 100 miles on a full recharge.
Smaller margin of safety?
Moloughney noted that in an early test of a completely depleted battery, he got only about 1 mile of additional range once the car's remaining-range indicator dropped to 0. BMW had estimated a margin of about 5 or 6 miles, he said, though he noted he did his tests on a day when the temperature was just 18 degrees F.
After that, the ActiveE barely crawled until he was able to recharge enough to get him back to his house.
In the Mini E, by contrast, he said he knew he had a safety margin of 10 to 18 more miles.
EcoMode fogging
The one drawback to the EcoPro mode proved to be anemic seat heaters--they were nice and toasty in Normal mode--and occasional fogging of the glass.
Cabin heating and ventilation are major energy draws in any car with a high-voltage battery, so the "Eco" setting usually dials down those accessories a lot. Moloughney would prefer that the cabin heating be dialed down more, but the seat heaters retained at a higher power.
Brief blasts with the fan cleared up the misting, and the car's good insulation mean that it stays warm once the car was pre-conditioned while plugged in or the occupants had warmed up.
Moloughney also noted his irritation that the car cannot be set to pre-condition the cabin at the same time each day. The smartphone app only gives him access to a 24-hour window, with no recurring setting mode.
One awkward moment on our test underscored the car's developmental nature: Using both friction and regenerative brakes in two-pedal driving coming uphill to a stoplight, the car simply shut down, with a message on the display saying it had a powertrain problem.

Tom & Meredith Moloughney get keys to first BMW ActiveE electric car delivered in U.S., Jan 2012
Enlarge PhotoIt rebooted itself and behaved fine thereafter, but Moloughney plans to seek an explanation from BMW about what happened. It is, he admits cheerfully, part of his role as a test driver for this new technology--or, as BMW calls them, an "electronaut."
The listed price of the BMW ActiveE is $59,500 plus an $850 delivery fee, for a total of $60,350. All 600 drivers, however, will lease the car for two years at a cost of $499 per month after a down payment of $2,250.
The ActiveE fleet of 600 cars in North America will be tested for two years, leading up to an expected September 2013 launch of the company's ground-breaking BMW i3 electric minicar

Very exciting to see BMW make progress and I look forward to seeing how the i3 performs.
Can't wait to see what is possible with the 2700 lbs i3.

Elon Musk has to be VERY satisfied with his team's efforts after reading this review. Back to the drawing board, Bimmer Boys.
As for price, the BMW ActiveE is $60,350 including delivery. The base model of the Tesla Model S will be $67,400 before any incentives (don't be misled by Tesla's annoying habit of quoting prices with the $7,500 Federal tax credit deducted) plus an unknown delivery charge.
But it's a somewhat specious comparison, since you can't buy an ActiveE at all. BMW will only lease 600 of them in the U.S., they'll take them back after a couple of of years, and they'll likely be dismantled and crushed.
But, of course, GM has to continually play the bad guy for making a completely logical, prudent decision years ago...
And GM making a profit off SUVs is bad, whereas Toyota/Nissan/Honda tripling SUV production in a decade (and losing money while doing it)is apparently a good thing. Oh, that's right, again, if GM does it, it's bad. Profit is a good thing sometimes.
You're smarter than that, Chris.
They have a lot of challenges ahead and haven't even sold 2,000 cars in nearly four years of business. Lets see how the Model S launch goes. I doubt if they'll have more than a couple hundred cars made in 2012 and then lets see if they can ramp up production in 2013 and not have massive quality issues. All that said, I really want to see them survive. You can say BMW isn't ahead of anyone because they still haven't sold any EV's and that's fair, but in that regard they aren't behind anyone either
John Briggs: you realize the legendary German building quality is largely a marketing myth right?
Fair enough. However, what I am saying is that an established company like BMW is more likely to deliver a quality product than Tesla on the Model S.
That said, Tesla seems to have a good track record with the Roadster. On the other hand, significant portions of the Roadster came from the established company Lotus. Still, seems like the battery pack, electronics, and motors Tesla has delivered are performing well.
Financially, how much the ActiveE cost , including sales tax? I paid $40,500 before the tax credit (including all charges) for SL model.
I really hope that Lithium-Air (Oxygen) technology proves to be viable & cost effective within 5-10 years to make EV a long distance car. BMW sees a market EV. Would love2C BMW
