Based on the same drivetrain as the Chevrolet Volt and Vauxhall/Opel Ampera, the ELR offers a 37-mile electric range before its 1.4-litre petrol engine is used to drive a generator and keep the battery topped up on longer journeys.

However, it shares no interior or exterior panels with its siblings, and the ELR debuts a Regen on Demand function allowing drivers to store kinetic energy from the vehicle’s movement as electricity for the battery, using paddles behind the steering wheel.

The 240-volt home charging station is supplied including installation and allows the battery to be fully charged in five hours. By comparison, recharging from a 120-volt domestic socket takes between 12.5 and 18 hours, according to Cadillac.

Uwe Ellinghaus, chief marketing officer, Global Cadillac, said: ‘The ELR's blend of leading technology with provocative design and fun-to-drive performance is set to bring new buyers to Cadillac and to electrification itself. Professional installation of the fastest home-charging unit is a natural way to mark the introduction of ELR to the luxury market.’
