Dubbed the 740e iPerformance, the plug-in hybrid features the same drivetrain as the already launched X5 xDrive40e, and mates a turbocharged 254bhp 2.0-litre, four-cylinder petrol engine with an electric motor, giving a combined power output of 322bhp and 369lb ft of torque. Official fuel economy figures are 134.5mpg, with CO2 emissions of 49g/km.
The 740e will be available in both standard and long-wheelbase forms, and also as an all-wheel drive xDrive variant. In this form, the 740e returns 122.8mpg and emits 53g/km of CO2. All models get an eight-speed automatic transmission as standard.
The 740e iPerformance can travel up to 25 miles on electric power alone (dropping to 23 miles in the xDrive version), and can sprint to 62mph in 5.6sec - the long-wheelbase version is 0.1sec slower while the xDrive variant is 0.1sec faster.
BMW’s Auto eDrive function allows drivers to choose how the 740e operates and features modes for pure electric driving and performance. Drivers can also select from the usual Eco Pro, Comfort and Sport modes too. The 740e can be charged in less than four hours from a domestic socket, or in under three hours from a wall charger.
Standard equipment on this hybrid 7 Series is generous and includes satellite navigation, BMW’s range of connected infotainment services, a digital display key, LED headlights and a mobile phone charger. The car also gets special graphics in its instrument cluster.
Interestingly, BMW is choosing to badge all of its future hybrid models with the iPerformance label, linking regular BMW models with the futuristic BMW i brand.
The hybrid 7 Series is one of three BMW hybrid models to launch in the past 12 months, with the 330e and 225xe being revealed in November of last year. They join the X5 xDrive40e, the i3 and the i8 in BMW’s growing hybrid and electric model range.
Pricing for the hybrid 7 Series has not yet been revealed, but top-end versions of the 7 Series start at £79,675, and that’s where BMW is likely to pitch the 740e iPerformance.
