BMW i3 With REx
In the Edmunds long-term test garage is a BMW i3 REx.
Recently, Edmunds put the i3 REx through its standard battery (pun intended) of tests, which includes acceleration, handling, braking, etc.
We'll focus solely on acceleration here, as the test methods from Edmunds reveals figures we've not seen published before.
Acceleration: (All runs with Traction Control on. Secondary runs are with the battery depleted and range extender recharging the battery) 0-30 (sec): 3.1 (w/ battery depleted 3.8) 0-45 (sec): 4.7 (w/ battery depleted 7.7) 0-60 (sec): 7.1 (w/ battery depleted 13.7) 0-60 with 1-ft Rollout (sec): 6.8 (w/ battery depleted 13.3) 0-75 (sec): 11.2 (w/ battery depleted no time)
1/4-Mile (sec @ mph): 15.6 @ 85.6 (w/ battery depleted 19.2 @ 64.7)
It's clear from these test results that the i3 REx is not peppy (0 to 60 MPH in 13.7 seconds is Geo Metro territory) when its battery is depleted. Additionally, the i3 REx was not capable of reaching 75 MPH in battery depleted operation.
