The ELR shares its drivetrain and platform with the Chevrolet Volt and Vauxhall/Opel Ampera, offering an electric range of around 50 miles but with the backup of a range-extending petrol engine for longer drives.

However, none of the sheet metal or interior parts are common between the Cadillac and its nearest siblings, while it adds a regen-on-demand feature via paddles behind the steering wheel to increase regenerative braking as required.

Thomas Sedran, president and managing director of Chevrolet and Cadillac Europe, said: ‘We at Cadillac see ourselves as a true ‘challenger brand’ in Europe and we fully understand that we have a lot of work ahead of us to make ourselves relevant to the European premium customer. Being a niche player, we have the opportunity to challenge the traditional approaches to marketing and selling premium vehicles.’

The ELR will join the ATS saloon and coupe, CTS saloon, SRX crossover and Escalade SUV due to launch in Europe by the end of the year, and Cadillac dealers will also be responsible for selling the Camaro and Corvette after Chevrolet is withdrawn from the region.

Uwe Ellinghaus, Cadillac global chief marketing officer, added: 'The engine of growth for Cadillac is our cars – with a fresh new take on premium. The unique personality of the brand makes Cadillac the distinctive new face in the crowd. Europe is a key region for any premium brand and will play an important part for Cadillac in the future.'
