Hybrid and plug-in hybrid electric cars are not nearly as fuel efficient as their manufacturers claims, according to a new trial by Consumer NZ.
The trial found, when measured at the pump, PHEVs used on average 73% more fuel than the manufacturers' claims, while hybrids averaged 20% more fuel use.
The trial was commissioned by the Ministry of Transport to assess the fuel use of five brands' PHEVs and hybrids to see how normal use compared with manufacturers' claims.
