Daimler is currently working on a new hybrid vehicle engine that the company calls a transmission-integrated electric engine. As the name suggests, the setup puts the electric engine (motor) into the automatic transmission.

According to Daimler, the setup is good to power levels of more than 15 kilowatts and the integrated setup could boost performance of the company's hybrid vehicles while also reducing fuel consumption. By containing the vast majority of the hybrid powertrain components within the transmission, the system could be utilized across vehicle platforms with relative ease.

The automaker will invest $56 million into its Berlin factory to convert a portion of the plant to work on development and production of the transmission-integrated electric engine for future Mercedes-Benz hybrid vehicles. Follow the jump for more information.

New electric engine for hybrid vehicles to come from Mercedes-Benz plant in Berlin
Berlin, Germany, March 30, 2010
  • Site to take over production of a key technology for the future
  • Investment of around EUR 40 million in development and production
  • Historical origins of electric engine construction are in Berlin
The Mercedes-Benz plant in Berlin is to produce a new generation of transmission-integrated electric engines for Mercedes-Benz hybrid vehicles from 2012 onwards. As a result of this decision, the site will add a key technology of the future to its production portfolio. The intensive collaboration between the plant and the research and development departments will create excellent conditions for the further development and production of the latest technologies.

With this decision, Mercedes-Benz Cars is continuing its strategy of building up technology for the electrification of drive systems as a core competence, also in production. The decision to award the contract for the development and production of the new transmission-integrated electric engine to Berlin was made as part of the overall strategy of actively shaping sustainable mobility. Furthermore, Daimler has also taken on a leading role in the development and production of battery cells and the future manufacture of lithium ion battery systems in two joint ventures with Evonik Industries AG.

Investment in future technologies

A hall with a surface area of 4,000 m² is currently being converted for the new scope of production at the Berlin plant. The company is to invest around EUR 40 million in total in the development and production of the new engine. The necessary machinery and equipment is to be set up in the new production buildings by early 2011. A total of 50 employees will be involved in the development and production of these electric engines at the site. The engines are expected to be used in Mercedes-Benz hybrid vehicles from 2012 onwards.

The electric engine is a transmission-integrated version, i.e. the electric engine is built in as part of the automatic transmission and can develop an engine power of 15 kW and more. It boosts performance by interacting with the combustion engine and lowers consumption by recovering energy during braking, for example, which charges the battery.

Tradition of electric engine production in Berlin

With a history going back over 100 years, the Berlin plant is firmly rooted in the German capital. The history of the electric engine has its origins here. Even at the end of the 19th century, the electric engine was already being regarded as an alternative to the combustion engine. Motorfahrzeug und Motorenfabrik Berlin-Marienfelde [Berlin-Marienfelde motor vehicle and engine factory], the precursor to the current Mercedes-Benz plant in Berlin, presented its first electric vehicle as early as 1898. The partner for the project was the Columbia Electric Company in Connecticut, USA, which continued to produce electric cars until 1918. The licensing agreement with the Berlin plant, which originated from the company Altmann & Cie. GmbH, was signed in 1897. In 1899, Motorfahrzeug- und Motorenfabrik Berlin-Marienfelde offered four different passenger cars based on the US patent. However, Columbia Electric's electromobile system was unable to keep up with the rapid development of the combustion engine, and production in Berlin-Marienfelde stopped in 1902. In the same year, Daimler-Motoren-Gesellschaft merged with Motorfahrzeug- und Motorenfabrik Berlin-Marienfelde, following a resolution passed on 16 August.

The Berlin plant currently produces V6 and V8 diesel engines and V12 biturbo engines for the Mercedes-Benz and Maybach brands. It also focuses on product development and production in the area of components and parts.
