Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L

Update on DOE Co-Optima project to co-optimize fuels & engines; goal of 30% per vehicle reduction in petroleum

Green Car Congress

The researchers suggest that there are engine architectures that can provide higher thermodynamic efficiencies than available from modern internal combustion engines; however, new fuels are required to maximize efficiency and operability across a wide speed/load range.

Camry hybrid, Ioniq 5 N reviews; Prius and Cybertruck recalls; Highlander EV: The Week in Reverse

Baua Electric

Available all-wheel drive, its ratings of up to 51 mpg combined, and a comfortable, spacious interior make it one of the most appealing Camry sedans yet. Mercedes has also, reportedly, scrapped its extended-range EV powertrains under development, at least partly because they were too expensive and seen as a technological patch.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

Unlike the vehicles fueled entirely by battery which must carry the weight of enough batteries to attain a desired range, the PHEV simply switches automatically to an efficient, non-electric engine using an energy-dense fuel when greater range is occasionally needed. Typical vehicles are parked for over 20 hours per day.
