Lotus unveils E-R9 next-generation EV endurance racer design study Lotus unveiled the E-R9, a new design study for a next-generation pure electric endurance racer that could be on the starting grid of circuits around the world for the 2030 season. The EV features a sleek fighter jet-style canopy centrally mounted in a delta-wing upper body. Innovations include advanced active aerodynamics with morphing body panels and vertically mounted control surfaces to assist with high-speed cornering. Lotus Engineering created the E-R9 as a technology showcase of its philosophy, capability and innovative spirit in the fields of advanced electrified powertrains and aerodynamics. E-R stands for Endurance Racer, while 9 is the car’s competition number carefully chosen in tribute to Lotus’ racing past. It was in a Lotus Mark IX that the race team made its debut appearance at the Le Mans 24 Hours, with company founder Colin Chapman among the drivers competing. The year was 1955, meaning the E-R9 race car concept—if raced in 2030—would be in celebration of the Mark IX’s 75th anniversary.
