Porsche Says “One-Pedal Driving Is Inefficient, Leading to Double the Losses”

Arguably top-of-the-line features of an electrical vehicle (EV) is one-pedal driving during which the automobile slows down without the necessity to physically apply pressure to the brake pedal. This is feasible due to the regenerative braking system in EVs, which uses the electrical motor as a generator and converts kinetic energy from the vehicle’s forward motion into electricity.

While this provides a greater driving experience for a lot of, it is just not essentially the most efficient option to decelerate an EV, based on Porsche engineers. As an alternative the German automaker decided to go along with a driving feature from internal combustion engine (ICE) cars, coasting, which it says is “more natural.”

In response to Martin Reichenecker, Senior Manager Chassis Testing at Porsche Engineering, coasting can be more efficient and the recuperation of energy only happens when the brake pedal is used.

In a recent article within the Porsche Engineering Magazine Reichenecker explained, “it is a more efficient way of driving, since it keeps the kinetic energy within the vehicle.” This compares to one-pedal driving which recuperates first, and only then converts the recovered energy back into propulsion, leading to “twice the losses.” (via GreenCarReports)

Porsche also says it expects the brake pads within the Taycan and their future EVs to outlast their usable life, and that they will probably be replaced due to their age and never because of wear. But that lack of use also can cause issues during which the brake discs accumulate dirt and dirt, but Porsche has provide you with a feature to maintain them clean.

“The vehicle brakes at regular intervals using the hydraulic system only, and without the electrical motors, to remove dirt from the discs,” Porsche explains.

Despite this, the Taycan still uses its electric motors to decelerate 90% of the time. The one time the hydraulic brakes are needed is when the automobile is travelling below 5km/h, a speed at which the electrical motors don’t generate enough power to decelerate the automobile.
