Trial Study Shows Mini E Meets Needs

Mini E
DAVIS, CA– UC Davis and the BMW Group have released the largest publicly available study of electric-car users. The study included over 120 families who drove the electric MINI E more than one million miles in California, New York and New Jersey from June 2009 to June 2010. The participants found the cars to be fun yet practical, easy to drive and recharge, and many said they would buy an electric car in the next five years, according to UC Davis researchers.

The results of the study provide valuable insight into the value of the new BEVs. The UC Davis study is part of a whole set of studies being conducted by the BMW Group on electric vehicles, which includes research in China, Germany and the U.K.

Through surveys of the participating households, and diaries and in-person interviews with a subset of more than 40 households, the UC Davis MINI E research team examined user behavior, infrastructure use, costs, environmental benefits, and other aspects of electric driving.

The study found the following:

By the end of the lease period, MINI E drivers were overwhelmingly in support of using renewable sources to charge their BEV. The drivers were strongly opposed to coal to generate electricity for their vehicles.

UC Davis Plug-in Hybrid Electric Vehicle Research Center director Tom Turrentine said the study highlights three new and potentially significant ways that drivers value BEVs. First, the MINI E meets drivers’ desire for a vehicle that is both environmentally friendly and fun to drive. Drivers loved the vehicle’s quick acceleration and quiet operation.

“What we heard over and over again in our interviews is how fun it was to drive. That’s in part because it’s a MINI and in part because of the feel of electric drive,” Turrentine said.

Second, drivers find value in using electricity as a fuel and in mastering their individual energy use through efficient driving behaviors. “The combination of limited onboard energy and extreme efficiency make BEVs the premier appliance for people to experience energy use,” says Turrentine. Additionally, the drivers learned to appreciate the car’s powerful regenerative braking function, which returns energy to the battery and allowed them to drive using a single pedal for acceleration and
braking.

Third, drivers like to develop their clean driving territory. “Drivers start talking about the MINI E as a special way to explore their region. They of course can go anywhere in their gas car, but they like to talk about where they can go in their MINI E,” Turrentine says.

While range is often held up as a limitation of BEVs, the MINI E’s range of around 100 miles was acceptable to most drivers most of the time. “We found that households adapted their driving around the capabilities of the vehicle and even explored ways to maximize the use of the MINI E,” said Turrentine.

By studying the MINI E drivers’ usage patterns and need for range, researchers were able to determine that strategic placement of charging stations could allow drivers to reach most of their desired destinations using a BEV that has a range of 90 to 100 miles. Most charging occurred at home, at night, and 99% of respondents said home charging was easy to
use.

“The MINI E studies are extremely valuable for us as they show that electric cars are already today offering an attractive mobility solution to a broader spectrum of customers. While reducing the tail pipe emissions to zero, the MINI E provides the fun that users expect when driving our products. The results of the UC Davis study have a direct impact on the development of all BMW Group electric vehicles to come,” says Ulrich Kranz, head of project i, BMW Group. “BMW Group now is developing the next generation of full electric cars, with the BMW ActiveE test fleet coming into the market in 2011 and the series production BMW i3 following in 2013.”

The all-electric BMW ActiveE will be available in select US markets beginning in late 2011, for a two-year lease at $499/month, with a $2,250 down payment. Details can be found at www.BMWUSA.com/ActiveE.
