Schrӧdinger’s Car: the plug-in hybrid conundrum
 Are plug-in hybrid vehicles (PHEVs) a rapid and practical route to carbon dioxide
reduction, or a uncontrollable and expensive diversion from other more promising types
of powertrain?
 Many vehicles are being launched with CO2 emissions below 49g/km on the WLTP cycle,
to gain CO2 ‘supercredits’ and tax advantages
 What does independent real-world testing tell us happens in practice?
 How dependent on driver behaviour are the CO2 benefits?
 Are the advantages of PHEVS being correcting represented in manufacturer marketing?
 How technology-neutral AIR Index ratings can help demystify the situation for policy
makers and car buyers.
