.. and, unfortunately, the app certainly is not accurate (or the GPS on my phone). The app showed the BMW do 0 - 60 in 5.8 seconds.. I'm sure that this can't be close to the actual number.. Car&Driver got 6.6 seconds I believe for the 2017 i3 BEV. I highly doubt that the car is actually 0.8 seconds faster..
That's what the drag racer app does. Torque Pro also has it.. However, the result seems off.. Car is not that fast even though I'm more than impressed how the BMW accelerates like that without tire spin and tiny tires. The Kona chirps the tires until about 45 mph.. no traction..
Tried the app on the Kona and only got 6.6 seconds from 0 - 60 mph.. Problem with the Kona is that the tires don't grip and tires come loose up to 45 mph.. It's crazy..
