Lithium-ion batteries highlight new sports car

JJAD's electric sports car will have lithium-ion batteries and has been designed for enthusiasts.

Design, engineering, and automotive specialist company JJAD is working to create an electric sports car using lithium-ion batteries. Managing Director Jim Dowle, who formerly worked on Gordon Murray’s team at McLaren, has designed the two-seat, purpose-built P1-E.

Performance targets include a maximum range of 370 km (230 mi) and a 0-97-km/h (60-mph) time of 2.9 s. Dowle had originally envisaged designing a car powered by an internal-combustion engine, but he decided to change the configuration to electric drive. Work on the prototype is starting in the U.K.

"It became obvious EVs would be part of the future," he said. "All the electric cars produced to date have been compromised in one way or another, and most have been of little attraction to the enthusiast driver. We decided that it was time to create an affordable electric sports car that combined the advantages of conventionally engined machines with those of electric ones."

JJAD is aiming to have a running prototype in about a year, with a manufacturer starting production possibly in 2012.

By designing for electric drive before prototype build, packaging was not compromised and performance enhanced, said Dowle. The P1-E is planned as an all-wheel-drive design, having two electric motors producing a combined 290 kW, with maximum torque of 800 N·m (590 lb·ft). A regenerative braking system will be fitted. Total mass will be about 1055 kg (2326 lb), with the body and chassis being made of composite materials.
