The two-door coupe now features recalibrated suspension and steering, as well as new brake hardware to improve the driving experience, while equipment includes the 4G LTE version of OnStar with an on-board WiFi hotspot and wireless charging pad for compatible smartphones.

Performance from the drivetrain, a re-tuned version of the system used in the Chevrolet Volt and Vauxhall/Opel Ampera, has also increased. The 2016 ELR produces 214bhp in Tour mode, compared to 181bhp for the previous version, and 233bhp in Sport, the latter bringing the sprint to 60mph down from 7.9 to 6.4 seconds.

Buyers can also add a Performance package, comprising new 20-inch wheels and performance tyres, a Brembo brake system, recalibrated steering and dampers and thicker Sport steering wheel. The 10% increase in lateral grip from the tyres reduces the standard car’s 39-mile electric range by around 10 miles, Cadillac said.

The 2016 ELR, will start at $58,495 (£39,584) net pricing after U.S. federal tax credits.
