Other technologies—such as efficiency improvements in gasoline engines as well as the rollout of hybrid electric power trains—offer more compelling and cost-effective pathways to reducing CO 2 emissions from European passenger cars, the ICCT says. For instance, hybrid electric vehicles and diesel cars in the small (e.g.,

The T-Hybrid (based on a Kia Optima) ( earlier post ) and the ADEPT (based on a Ford Focus) ( earlier post ) both utilize an advanced 48V lead-carbon battery system with bolt-on electrical components that allow for significant engine-downsizing without loss in performance. This concept vehicle is powered by the Optima’s existing 1.7

With high power density, a recharge time of 2-3 seconds and more than one million life cycles, ultracapacitors are unique in their ability to not only reduce CO2 emissions but also increase performance and be cost-effective for manufacturers.

Cummins has developed an E-85-specific engine and powertrain that reduce carbon dioxide emissions by as much as 80% compared with a baseline gasoline-powered medium-duty truck. It delivers the power (up to 250 hp / 186 kW) and peak torque (up to 450 lb-ft / 610 N·m) of gasoline and diesel engines nearly twice its 2.8-liter

liter i-DTEC offers maximum power output of 118 hp (88 kW) at 4000 rpm, and 300 N·m (221 lb-ft) of torque at 2000 rpm). By downsizing from the outgoing 2.2L This is a 15-gram drop (13.6%) from the 110 g/km emissions of the enhanced 2.2L i-DTEC introduced in September 2011 at the Frankfurt show. Earlier post.).

The Delphi study assessed the technology of downsizing and turbocharging; GDI fueling and its synergies with turbocharging; and an analysis of downsized 3-cylinder versus 4-cylinder engines. Downsizing can be accomplished via reduction in the number of cylinders, and/or a reduction in the displaced volume of each cylinder.
