Lotus Evora 414E Concept – Click above for high-res image gallery

Lotus Engineering has reached an agreement with the Spanish Fagor Ederlan Group to develop and produce a small engine for use as a range extender in electric vehicles – a system similar to that found in the Chevrolet Volt. Lotus first showed its 1.2-liter inline-three engine at the Geneva Motor Show in the Evora 414E and Proton Emas concepts.

Both cars used a similar series hybrid powertrain architecture, where an electric motor provides the drive torque while the engine only drives a generator to sustain the battery after the plug-in charge has been depleted.

Because this new engine is designed specifically for use as a range extender rather than a primary power source, Lotus has been able to optimize the efficiency and reduce the weight. An adapted off-the-shelf engine like the one in the Volt is still designed to hold accessories like the alternator, air-conditioning compressor and power steering pump. Lotus has left out these structures for a lower cost and mass.

Lotus and Fagor Ederlan will take the 47 horsepower engine to production and offer it up to any automaker that wants to build an extended range electric vehicle, but no production timing or customers have been announced yet.

PRESS RELEASE

Lotus Range Extender Engine set for production

A collaboration between Lotus Engineering and Fagor Ederlan will develop the Lotus Range Extender Engine for series production.


Lotus Engineering, the automotive consultancy division of Lotus Cars Limited, and Fagor Ederlan, part of the Mondragon Corporation Cooperativa, the biggest co-operative group in the world, have completed a joint technical and market study analysing the best route to production for the Lotus Range Extender Engine. The study has culminated with an agreement for Lotus Engineering to develop the engine for series production and sale by Fagor Ederlan for the global automotive market.

The three-cylinder, 1.2 litre Range Extender engine from Lotus Engineering has been designed specifically for series hybrid vehicles and the production engine will offer a fast route to market for manufacturers wanting to source a dedicated range extender. The high efficiency, low mass design will enable low emissions vehicles to be produced cost effectively across a wide range of hybrid vehicle applications, as already demonstrated in both the Lotus Evora 414E Hybrid and the PROTON Emas concepts, which were shown at the 80th International Geneva Motor Show this year.

      Will it come in colors other than Zax Sauce?

      So then what happens when those accessories are needed? They just further drain the battery? I don't see the benefit of simplifying here, unless those accessories are not going to be present in a prospective application.

        I am sure the car engineers have thought of that possibility.

        To add to my previous statement, this engine is meant for an EV, one that already has or doesn't need these components/accessories, ie think a Tesla Roadster ER.

      That color is gorgeous.

      Even though it is smart paring down on non-essentials, complexity and weight for a dedicated range extender engine, i am forever puzzled why nobody is building a diesel engine for this purpose.
      I understand that diesels are a bit heavier, and more expensive, but it would seem that one of the MANY portable diesel generator engines could be made clean, simple, and cheap enough for this use.

      The The Polo BlueMotion is powered by a 1.2-liter three-cylinder turbo-diesel derived from the 1.6-liter TDI four-cylinder engine and it makes 75HP and gets over 70MPG (U.S.), so it would seem like a relatively easy task to build a smaller, simpler version of an engine like that, perhaps 750CCs making 50HP, and getting closer to 100MPG (when running in range extender mode).
