The Proton Concept Car, which will be unveiled at next week’s Geneva Motor Show, will showcase a series hybrid drivetrain designed and developed by Lotus Engineering.
Integrated into the Italdesign penned concept is the Lotus Range Extender engine, which uses a 1.2-litre three-cylinder engine to replenish charge in the battery and provide electrical power for the drive motors when battery levels are low. This method is much like GM’s E-REV system in the Chevrolet Volt, where the internal combustion engine does not power the wheels, and only acts as a “generator”. The battery can also be recharged via household sockets to achieve initial electric-only operation. No range is given for the pure electric mode, just a mention that it’s “acceptable”.

Dr Robert Hentschel, Director of Lotus Engineering said: “The hybrid drivetrain of the Proton Concept is another example of Lotus Engineering’s expertise in electrical and electronic systems and efficient performance engines. The high efficiency Lotus Range Extender engine, which we unveiled to great acclaim at the Frankfurt Motor Show last year is perfectly suited for the advanced series hybrid we have created for the Proton Concept city car. It is an exciting example of the diverse range of highly efficient total propulsion systems that Lotus Engineering continues to develop for its partners and clients.”
