Available in standard and long-wheelbase lengths, the 745e pairs a six-cylinder petrol engine with a battery and electric motor to provide both four-wheel drive and increased urban efficiency.

The 3.0-litre petrol engine produces 290hp on its own, while the electric motor can push out 115hp. Together the two give a total system output of 400hp and maximum torque of 600Nm, delivering considerable performance for a luxury limo.
The 0-60mph dash takes just five seconds for the standard length model, while the long-wheelbase models are actually quicker because they employ all-wheel drive. This shaves a tenth of acceleration times, hitting 60mph from rest in just 4.9 seconds.
Both cars use the same 12kWh battery pack, which gives the short-wheelbase model a maximum electric range of 36 miles. Long-wheelbase models can manage 34 miles. Both will do up to 87mph in electric mode, too.
BMW claims impressive fuel economy and emissions ratings for the hybrid 7 Series, though it’s worth noting these were achieved under less taxing NEDC tests rather than the more accurate WLTP. Still, a maximum 141mpg and 48g/km of CO2 are impressive results for such a large machine.
Interior fittings are just as luxurious as on any other models in the updated BMW 7 Series range, with the only visible difference for passengers being a slightly smaller load bay and bespoke hybrid instrument panel.
The new models are set to go on sale in the spring. BMW UK has announced that the short-wheelbase 745e will be priced from £76,815 on-road, while long-wheelbase 745Le xDrive models start at £83,560.
