The Porsche Taycan is a bit of an oddity in the world of electric vehicles. Instead of beefing up its regenerative braking system with one-pedal driving, it just works like a gas-powered car: the brakes come on when you press the brake pedal. Now Porsche explains why its upcoming Macan EV also lacks one-pedal drive.
One-pedal driving is exactly what it sounds like; When you take your foot off the accelerator, the electric brakes come on, slowly slowing the car down. This generates electricity for the EV’s battery, providing a slight increase in range. But in a recent press release, Porsche says that driving with one pedal is a bad idea that wastes energy.
According to Porsche research, one-pedal braking wastes kinetic energy by decelerating the vehicle at the wrong times. Allowing the car to slide is a “more efficient way to drive” since braking (and regeneration) only happens when the driver really needs to slow down.
This of course means that the Taycan and Macan drive more like gasoline cars (which many drivers will prefer). But Porsche still boasts an efficient regenerative braking system: It claims that high-end configurations of these EVs can regenerate about half a mile of electricity when slowing down from “high speeds” (presumably highway speeds).
It’s an interesting idea that appeals to many drivers, who may not be interested in one-pedal driving. I should also point out that rival automakers such as BMW are slowly moving away from one-pedal driving. And most electric vehicles (and hybrid cars) allow you to disable drive with a single pedal.
