This is BMW’s new ActiveHybrid 7, a hybrid limo which will compete with the Mercedes S400 Hybrid and Lexus LS600h as the car of choice for the rich but eco-conscious businessman.

Not quite. Both car use the same 4.4-litre twin-turbo V8, but the hybrid X6 is more performance biased. So while the X6 has two electric motors, nickel-metal hydride batteries and an electric seven-speed CVT transmission, the 7-series features just one motor (sandwiched between the engine and torque converter) but an eight-speed automatic and lithium-ion batteries.

The total output of the engine and electric motor is 459bhp and 516lb ft. That’s 19bhp and 59lb ft down on the X6, but with less weight to lug, it’ll sprint to 62mph in 4.9 seconds, seven-tenths quicker than the SUV.

The 29.1mpg and 219/km figures also best the hybrid 4x4, and the equivalent V8-engined 7-series (which does 24.8 and 266g/km), but can’t match the 39.2 and 192g/km CO2 of the 730d. It won’t matter to UK buyers though, because BMW isn't planning to engineer the ActiveHybrid 7 for right-hand drive. Shame.

With an eight-speed auto, the ActiveHybrid 7 is the first automatic BMW with stop-start, and the battery back-up means the electric air-con systems can keep running even when the engine is switched off.

And to make it stand out from lesser Sevens, there's special aero-optimised 19-inch wheels, ActiveHybrid badges and a unique Bluewater paint.
