With its approaching Chevrolet Bolt electric car, General Motors ( GM ) hopes to introduce the theme of one-pedal drive to the mass market. As with hybrids and other electric cars, the Bolt features regenerative brake, engineering that generates electricity from the act of slowing the car – energy normally lost as heating system. The car has four driving modes, each with increasingly more aggressive regenerative brake.
In three of the four modes, the Bolt will slow to a stop rigorously based on how drivers use the accelerator. In those modes, the brake pedal will be for emergency reception only. Without any other changes to the vehicle ’ randomness powertrain, GM engineers estimate that single-pedal drive will boost the electric cable car ’ second range by about 5 %.

From experience, I can say driving without brakes works. I started minimizing brake habit about 10 years ago, and I ’ ve found that it ’ s a practice that forces more situational awareness. You have to pay attention to anything that might slow you down, and to remember where stoplights and stop signs are sol you know when to start coast. You quickly realize how inefficiently some people drive. I exit the expressway on my commute home on a steep hill that has a stoplight at the end of it. even when the unhorse is green, traffic generally forces drivers to stop at the top of the hill. Yet every day, I watch drivers accelerate up the hill, only to slam on their brakes at the peak. If I ’ megabyte already going 65mph, that momentum is more than sufficient to get up the mound without spending another ounce of fuel. technology is improving fuel efficiency, but changes to driving habits could besides have a boastful impingement. GM appears to be combining the two approaches in its following electric car .
