Back in 2006 when the Chevrolet Volt was first conceived, its extended-range electric (ER-EV) powertrain was originally dubbed E-Flex as its configuration was designed to be flexible. The only part of the system that was constant ...

Last March at the Geneva Motor Show, Lotus announced its new Omnivore research engine. The Omnivore is a two-stroke direct-injected engine designed to take advantage of the latest in electronic engine management and run on just about any liquid fuel (hence the name). In the time since the initial ...

Since our first encounter with General Motors' HCCI (homogeneous charge compression ignition) engines in August 2007, the powertrain research engineers at GM's Tech Center in Warren, MI have continued plugging away at the technology, trying to turn it into a marketable reality. The basic premise of ...

General Motors and the University of Michigan have been working together on vehicle technology for 50 years, and a new institute will take the long-standing relationship to the next level. GM researchers will work with U of M faculty and students to develop new battery, engine, manufacturing, and ...

We've talked about homogeneous charge compression ignition (HCCI) engines in the past, particularly how their complex process of producing energy equals that of a diesel in terms of efficiency, while not requiring expensive exhaust after-treatment systems to clean up emissions. Billed as the ideal ...

Ford is looking for ways to pack their automobiles with innovative technology that achieves the seemingly impossible goal of using smaller, more efficient engines while still delivering the performance wallop customers are demanding. Not only is the Blue Oval seeking more involvement from their ...

We're not gonna try to explain all the physics involved in this new engine design. That's for all you Autoblog readers with engineering degrees to do in the comments. But, from what we understand, MIT researchers have taken a long hard look at an engine design called homogeneous charge compression ...

The aptly named Diesel Forecast is reporting on a diesel technology discussion involving BMW, Volvo, Audi, and Bosch, and the path that each may take to address the increasingly-stringent emission requirements in the U.S. and in Europe. BMW, for its part, does not envision bringing over diesels to ...
