How the iBrand works

BMW i3 Concept
The i3 Concept has an electric engine on the rear axle. It delivers 125 kw/170 hp and 184 lb.ft of torque, which is available from the standing start. Acceleration takes 7.9 seconds for the sprint from 0-62 mph and 3.9 s for 0-37 mph. The acceleration which is important for overtaking (50-75 mph) takes 6 s. The top speed is (legally) limited at 93 mph.

Fully charging the lithium ion battery pack takes 6 hours through a house hold socket and fast charging for an 80 percent load costs only one hour.

Fully charged the range of the i3 will be between 80 and 100 miles. Drivers who need to have a longer range will get the option to have their BMW i3 fitted with the REx range extender, a small gasoline engine that drives a generator to maintain the battery charge level to ensure the vehicle can continue to drive on electric power Energy is recuperated by deceleration and braking. A special coasting facility provides a user-friendly character by means of the unique single-pedal control: when the driver eases off the pedal, the electric motors zero torque control keeps the drive train disconnected as long as the pedal is in this position. The vehicle now coasts without consuming power, driven by its own kinetic energy.

The electric vehicle has a wheelbase of 101.2 inches, while length, height and width are 151,6, 60,6 and 79.1 inches respectively. The cars curb weight is 2.755 lbs.

  • It’s encouraging to see BMW showcasing its test vehicles but it’s got a way to go to catch up with some of the other manufacturers. I hope they have a serious wish to be contenders in the EV technology race as opposed to be seen to be doing something for the publicity sake of it!
