Official: Lotus will build Range Extender engine for hybrids

Article by Christian A., on August 29, 2010

Fagor Ederlan has entered into a partnership with Lotus Engineering to collaborate on technology to make the Range Extender engine, which was presented last year at the 2009 Frankfurt Auto Show.

It will take some time yet before production begins but already, Lotus and Fagor Ederlan have already completed a joint technical and market study. Both sides concluded that the range extender is worth manufacturing.

The 3-cylinder 1.2l engine, which will be used in a series of hybrid vehicles, has an aluminum monoblock construction. Inside this structure is where the cylinder block, cylinder head and exhaust manifold are found in one casting. As a result, cost and mass are reduced as the engine weighs just 85 kg. This unit works with alcohol-based fuels and/or gasoline.

The range extender delivers 35 kW (48 PS/47 hp) of power at 3,500 rpm through an integrated electrical generator, which converts mechanical energy to electrical energy and then distributes it to the battery pack. The same electrical generator works as an engine starter.

Generator is installed to the engine via the crankshaft. It can sustain vehicle operation beyond what batteries provide.

Fagor Ederlan Group is one of the leaders in the field of Chassis and Powertrain Engineering, offering products that provide integral solutions in the market. In fact, Fagor Ederlan Group counts as clients all major auto companies as well as Tier 1 suppliers, allowing it to share and discern the challenges of the market as well as provide a customized response to their demands.

Because of its clear service approach, the Fagor Ederlan Group was able to penetrate into the global market as a cooperative company. In fact, as a global supplier, Fagor Ederlan boasts of having 15 manufacturing sites and production alliances across the main market regions of Western and Eastern Europe, Mercosur, Asia and NAFTA. Operating within the Mondragon Corporation, Fagor Ederlan employs over 3,500 people around the world.

Its objectives include the generation of jobs in a way that’s sustainable and that strengthens its social commitment.

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.
