Based on detailed model-level data for US light-duty vehicles from 1980 to 2006, a recent analysis by a UC Davis researcher found that if weight, horsepower and torque had been held at their 1980 levels, fuel economy for both passenger cars and light trucks could have increased by nearly 50% from 1980 to 2006.

The engine should yield fuel efficiency gains of more than 50% compared to a downsized, turbo-charged gasoline direct injection engine, while reducing the overall cost of the powertrain system, said Fabien Redon, Vice President, Technology Development at Achates Power.

The FEV data are combined with supplemental data to generate CO 2 cost curves for ten EU vehicle classes (diesel B, C, D, E, SUV, and LCV classes and gasoline B, C, D, and E classes). These individual class curves are then sales weighted to estimate fleet average compliance costs for a range of potential CO 2 standards. Earlier post.).

That front-drive mode gets the car a green light in cities like London and Rome as they begin to bar polluting cars from their downtown areas. You switch the mode on by dialing it up on the Ferrari’s dramatic steering wheel, which integrates a cool arc of LED lights on its carbon-fiber rim to cue drivers to shift.

The more efficient combustion engine technologies, with their enabling of downsizing, come in compatibly with hybridization, with hybridization and electrification playing a larger role over time. The further downsized next-generation technologies can be very synergistic within hybrid applications. Planning background.
