BMW i3 REx Road Test Yields 34 MPG, Plus Noise Levels Of The REx In Operation (video)
With the first BMW i3 landed at port today in New York, the good fellows over at ForoCochesElectricos have done something we have longed for here in the United States for quite some time – thoroughly test the BMW i3 REx.
More specifically, put both an MPG number to the BMW, but also a sound to it – after the battery has been completely exhausted.
As for the efficiency, a 100 km trip would net a result of about 7 liters of gasoline, which works out to be 33.6 miles per gallon. ForoCochesElectricos explains the result thusly (translated from Spanish):
“For consumption we have filled the tank of i3. A deposit for up to 9 liters. We conducted a driving circuit including a stretch of 17 kilometers within the city and a stretch of 19 kilometers by highway, running exactly 100
mileskm. Always at legal speed, both 50 km / h maximum in city’s 120 km / h on the highway. All in a circuit.
After 100 kilometers, back to the same gas station to refuel. And refuelled to full with 7.68 liters in total re-introduced. We can put a margin of error of 10%, as the filling in this second occasion seems to have been to limit the capacity of the tank, which would give us a figure of about 7 liters per 100 kilometers.”
As for the BMW i3 REx’s abilities when the car has been juiced, they had some issues under extreme conditions. While driving 120 km/h (75 mph) before a rather steep slope, the BMW has lost 50km/h (31 mph) by the time it had reached the summit. Starting from 60 km/h (37 mph) netted them an end result of about 30 km/h (20 mph).
The tester does note when used normally that if the BMW i3 “gets some wind” on the flat area with the battery depleted, “within seconds we have new energy to circulate normally.” Morale of the story? Don’t completely exhaust your battery at the very bottom of a mountain.
