Mitsubishi Motors Corp has delayed the introduction of its Outlander plug-in hybrid (PHEV) model in the US market until 2015 due to supply constraints.

The delay – the model was to be launched in the US in the autumn of 2014 – is because of bottlenecks in battery production at Lithium Energy Japan (LEJ) and juggling battery demand between the Outlander PHEV and the i-MiEV electric car.

European retail sales of the Outlander PHEV began in October and Mitsubishi has reported strong interest in the model across the world.

In September, Mitsubishi doubled production capacity for the Outlander PHEV at its Okazaki plant near Nagoya to 4,000 units a month (or nearly 50,000 units a year).
