As part of the automaker's EfficientDynamics technology platform, the use of brake energy regeneration has been added to both gasoline- and diesel-powered BMWs.

While brake power regeneration is something most drivers relate to certain types of hybrid vehicles, some OEMs are adding it to ICE-powered vehicles as well, including BMW. The variable displacement oil pumps, according to Cowland, also enable the oil output of the pump to be tailored to the demand of the engine rather than pressurizing and then recirculating excess fluid. "An example of such technology is the integrated exhaust manifolds used on the Pentastar engine." "From a combustion perspective, we are adding technologies that allow us to operate as close to the stoichiometric air/fuel ratio as possible without the need for fuel enrichment to manage exhaust temperatures," Cowland said. For example, using start/stop technology to stop the engine at idle and seamlessly restart it when the brake is released, and advanced battery charging that helps to charge the battery from regenerated vehicle kinetic energy.įor Chris Cowland, director, advance and SRT powertrain engineering at Chrysler, optimization of existing combustion, thermodynamic, and gasoline exchange technologies, as well as improving mechanical processes, will increase the overall efficiency of the ICE. GM is also increasing its attention to what it calls "opportunity-type" controls. He added variable cam phasing, direct fuel injection, reducing engine accessory loading, electric power steering, improved vehicle aerodynamics, increased cooling airflow sealing, and reduced tire rolling resistance to the list. "Great examples of technologies that improve vehicle efficiency include added transmission gears (e.g., 6-speed versus 4-speed) lowering engine operation speed, enabling lower numerical axle ratios, and, in many cases, increasing performance and capability," Clark said.
