Soot and Spin: Two Plug-in Paradoxes

Plugs and Cars

Paradox 1 - Soot: There's an apparent emissions paradox with plug-in hybrids (PHEV): Driving longer distances on battery power means more cold starts as the internal combustion engine (ICE) stops and starts up again after the batteries deplete. UPDATE: Felix Kramer of Calcars informs me that the vacuum bottle is standard on 2004-2008 Prius.)
