The Corvette Stingray might have grabbed most of the attention at this year’s North American International Auto Show in Detroit, but the launch of the new 2014 Cadillac ELR coupé is perhaps more significant.
That’s because it takes GM’s Extended Range Electric Vehicle (EREV) technology from the compact Chevrolet / Holden Volt and Vauxhall / Opel Ampera and, for the first time, puts it into a luxury car.

In theory the EREV powertrain has the environmental and running-cost benefits of an electric vehicle without any of the range anxiety. Consisting of a 1.4 litre petrol-powered electric generator, an electric motor and a T-shaped lithium-ion battery pack, its total system output is rated at 207 bhp (154 kW / 209 PS).
The Cadillac will run in electric-only mode for around 35 miles (56 kilometres), which should be enough for many daily commutes. That figure goes up to over 300 miles (480 kilometres) when the petrol generator is employed as well.
Trips to fuel stations could be a rare occurrence though, since the battery pack can also be recharged using a 120 V outlet or a 240 V dedicated charging station. The latter option is expected to take around 4.5 hours.

The smart styling of the 2+2 ELR coupé is virtually unaltered from that of the Converj concept, which was first seen back in 2009. An evolution of Cadillac’s ‘Art and Science’ design language, it incorporates prominent vertical head- and tail-light clusters, taut surfacing details and large 20” wheels with low rolling-resistance tyres.
ELR assembly is due to begin in late 2013, although Bob Ferguson, Cadillac global vice president, has stated: “It will be a specialized offering produced in limited numbers.” The first North American deliveries should then follow in early 2014.
Of course, pricing is bound to be a major factor in determining sales volumes but, for the time being, Cadillac is keeping quiet on the subject.
Another unknown is what plans exist for offering the ELR in the UK. While eventually it will be available in Europe, the business case for a right-hand drive version is probably not strong.
