Although real-world fuel economy improvements from GDI technology alone are close to 1.5%, they can reach 8% by downsizing and turbocharging the engine, which can be achieved on GDI engines without loss of power compared to PFI engines. The EPA GHG program is aimed at reducing tailpipe CO 2 emissions. —Saliba et al. of the data.
