2017 Chevrolet Bolt: Testing the EV at Its Limits

by Michael Massey, Vehicle Testing Assistant

2017 Chevrolet Bolt EV

Electric cars and test tracks don't typically mix very well. That didn't stop us from bringing our new long-term 2017 Chevrolet Bolt EV out to our test facility to see what it could do. Even if it doesn't generate impressive acceleration numbers, pushing it to the limit still provides some useful information.

Take the jump to see how it stacked up against other electric vehicles we've tested.

Acceleration comments:
Strong off the line. Feels quick. No wheelspin even with traction control off, unless you're on a slippery surface. Sport mode doesn't really feel all that different at full throttle, so it's likely just altering accelerator response. We shaved a tenth off on the third run (compared to the second run) using Sport, but the key-up run (first run) was the quickest with the batteries at their fullest. No power braking here; overlapping the brake and accelerator only slows the rate you'll leave the line. Just going quickly from brake to throttle with your right foot works best.

Braking comments:
Under full antilock braking, the Bolt sometimes skews slightly to one side; other times it remains straight. This is essentially on the same stretch of pavement. There isn't a ton of noise from the ABS, but there is a lot of tire squeal. The brake pedal has a light effort but isn't overly soft. And under full pressure the pedal maintains a progressive feel. That's because, despite what we might expect, the brake pedal is entirely hydraulic, which means no regenerative braking. Braking distances are relatively constant, varying only as much as 3 feet. There's marginal nosedive as well, and the Bolt remains pretty flat under max braking.

Handling comments:
Steering is pretty responsive. It is not super quick, but there's a fair amount of sensation coming through the steering wheel, at least enough to know when you're losing traction at the front wheels. Stability control can be turned off but only temporarily. As soon as you go over a certain speed, it comes back on automatically. However, keeping traction control off allows you to drive a little more freely. During skidpad runs with traction control on, the torque of the motor is heavily limited as the systems try to eliminate wheelspin as much as possible. We had better success with traction control off.
