The latest generation of the BMW 7 Series Hybrid gets a little bit of an “i” flavor with the new BMW 740e and its long and all-wheel-drive version, the 740Le xDrive. These model boast a four-cylinder engine with an electric motor, good for a total of 326 hp.

So although the size of the motors are different, because the recipe is so similar to that of the i8 powertrain, BMW 740e has the same sort of power output as the hybrid sports car. Whether that’s enough for a car as bulky as the 7er, well, the regular 740e sprints from 0 to 60 mph in 5.4 seconds and the xDrive version in 5.3 seconds, and both are limited to 155 mph. We have a sneaking suspicion BMW is deliberately underestimating their cars again.

But the biggest thing about a hybrid car of any sort is the fuel economy, and BMW 740e iPerformance does not disappoint in that aspect. The rear-drive SWB version records a combined fuel consumption of 134.5mpg and the Long AWD model 117.7mpg. CO2 emissions are 49g/km and 54g/km respectively, and the electric motor provides 29 miles of zero-emission driving as well. So the trendy CEO that will drive these things can boast to his colleagues when they are lunching at a high-end restaurant how he’s car is saving the planet.

Both models are packed with are packed with all of the safety, connectivity and convenience equipment you’d expect from a 7er, including LED headlights, the BMW Display Key, the ConnectedDrive navigation package, smartphone integration with an inductive charging. The BMW 740e is priced in the UK from £68,330 and the xDrive from £74,880, but unless you want to go off-roading in your luxury saloon you don’t need the all-wheel-drive.
