But gasoline engines are gaining ground against diesel engines thanks to a suite of efficiency technologies, such as direct injection, turbocharging and downsizing, cooled EGR, and variable valve timing. For instance, hybrid electric vehicles and diesel cars in the small (e.g., Renault Clio) and lower medium (e.g.,

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.
Cars That Think

Call it Peak ICE—the last hurrah of a technology that governments are ushering off the stage to combat climate change. Automakers are finding it difficult to challenge those boldface numbers with internal combustion alone, especially as engines are relentlessly downsized to meet regulations. And don’t forget sound.

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. In fact, the optimized PHEV is much more efficient as a long range liquid fuel vehicle, because the engine is downsized. This helps to explain the climate changes we are now experiencing.

While at face value this announcement looks like a win for the climate movement, there are provisions in the EPA's proposal that will cause it to fall short of the Administration's purported ambitions. They recognize that such a meager incremental improvement is insufficient to address the scourge of climate change.
