Proton plug-in hybrid: the platform
February 23, 2010 § Leave a comment
Here’s what lies under the surface of the Italdesign-styled Proton plug-in hybrid. Developed by Lotus Engineering (owned by Malaysian firm Proton), the powertrain incorporates the Lotus Range Extender engine, designed specifically for a hybrid system. This is a three-cylinder, 1.2-litre unit, which also acts as a generator to recharge the batteries and drive the motors; it delivers low emissions and works via a single-speed transmission. There is an ‘acceptable’ electric-only range for city use, says Lotus, boosted by recharging from a domestic AC power socket.
