First up is a slick 356-horsepower all-wheel-drive plug-in diesel-hybrid concept that BMW claims accelerates like an M3, sips gas like a Toyota Prius and can go 31 miles on battery power alone. It’s called the Vision Efficientdynamics Concept, and we’ll see it later this month at the Frankfurt auto show.
No, Vision Efficientdynamics Concept doesn’t exactly roll off the tongue. But the name aside, BMW has a dynamite idea on its hands here.
The EfficientDynamics is a 2+2 four-door hybrid that combines M Series performance with better fuel efficiency and less emissions than you see in many compacts. BMW performs this magic by marrying its ActiveHybrid technology with an extremely economical engine and excellent aerodynamics. The result is a concept car with a top speed governed at 155 mph and a zero-to-62 acceleration time of 4.8 seconds. More impressive, the car gets 62.2 mpg and emits a Prius-like 99 grams of CO2 per kilometer.
The lithium-polymer battery pack sports 98 cells. It delivers 8.6 kilowatt-hours for driving the car, and BMW says the serial arrangement of cells has gross storage capacity of 10.8 kilowatt-hours. The pack weighs 187 pounds and BMW says it doesn’t need an active cooling system. BMW says the battery recharges in 2.5 hours at 220 volts.
So far the Vision is just a concept. Still, BMW has made it clear it plans to make sustainability a cornerstone of its lineup, so we’re sure to see some of the technology in road cars before long.
