“The Executive Board at Porsche AG has given the green light to the development of an LMDh prototype,” explains, um, Porsche. LMDh cars will form the top tier of the World Endurance Championship and North American IMSA WeatherTech Sportscar Championship from 2023, so there’s a bit of a wait.

The new category allows Porsche “to fight for overall victories with a hybrid system at the Le Mans, Daytona and Sebring classics without breaking the bank”. We’re told these cars are built on an upgraded LMP2 chassis, while the spec for the hybrid system, including the control electronics, is all standardised. Each racer will weigh around 1,000kg and feature aforementioned hybrid powertrains kicking out some 680bhp.

“We hold a record with our 19 outright wins at the 24 Hours of Le Mans and we’ve climbed to the top podium step many times at major races in the USA,” explains Porsche’s Motorsport VP Fritz Enzinger. “We can continue this tradition with an LMDh vehicle while at the same time keeping costs reasonable. There has been huge interest from other manufacturers.
