Proton hybrid by Lotus

Lotus Engineering will unveil a new series hybrid drivetrain, together with its range extender engine, at the Geneva Motor Show, and it will appear in a Proton city car concept.

Lotus Engineering, the automotive consultancy division of Lotus Cars Limited, has designed and integrated the complete drivetrain, including the electrical drive system with single-speed transmission, which delivers low emissions, optimised performance and acceptable electric-only operating range for city use.

For longer journeys, when the battery charge level falls, the 3 cylinder, 1.2 litre Lotus Range Extender engine is used to replenish the charge in the battery and provide electrical power for the drive motors. The battery can also be recharged via an AC mains domestic outlet to achieve initial electric-only operation, in other words it’s a plug-in hybrid.

The Proton hybrid city car concept has been styled by Italdesign and will be unveiled on the Italdesign stand at the Geneva Motor Show.

The high efficiency Lotus Range Extender engine was unveiled at the Frankfurt Motor Show last year.

Lotus Cars Limited is a subsidiary within the Proton group of companies. Established in 1983, Proton is Malaysia’s largest manufacturer of cars.
