Cackette was in effect suggesting that the future tailpipe emissions baseline (LEV III) for light duty passenger vehicles—both diesel and gasoline—was likely to be or to approximate CA SULEV/US Tier 2 Bin 2. We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. John Kirwan.

At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.
