CO2 Downsizing Light Pollution 
Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. l/100 km)—the average fuel economy of the in-use United States light-duty fleet in 2014.

It is a high octane fuel with combustion characteristics that allow engines specifically designed for methanol fuel to match the best efficiencies of diesels while meeting current pollutant emission regulations. A bridging option is to use methanol derived from natural gas, with a CO2 intensity that is no worse than conventional fuels.

A new vehicle type-approval test procedure for the EU, the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), will likely reduce that gap beginning in 2017. With respect to light-commercial vehicles, CO 2 standards as low as 90–100 g/km (NEDC) can be achieved with few or no electric vehicles in the new-vehicle market.

The Environmental Protection Agency (EPA) recently released a detailed proposal designed to strengthen greenhouse gas emissions standards for light-duty vehicles. Vehicles with larger footprints are allowed to generate more CO2 than vehicles with smaller footprints. Under the current rules, credits expire after five years.
