1 min read
Sports car firm Lotus is to unveil its Proton Concept car (pictured) at the Geneva Motor Show, showcasing an advanced series hybrid drivetrain, designed and developed by the company's automotive consultancy division.
The Proton Concept is a plug-in series hybrid city car, for which Lotus Engineering has designed and integrated the complete drivetrain, including the electrical drive system with single-speed transmission, delivering low emissions, optimised performance and acceptable electric-only operating range for city use. For longer journeys, when the battery charge level falls, the three 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.
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 IAA 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."
