The 740e iPerformance is BMW's range-topping plug-in hybrid saloon
It promises CO2 emissions as low as 49g/km
This is likely to make it a hit among company car users...
...particularly as it has the lowest P11D value of all the non-diesel BMW 7 Series models
Its low list price is partially thanks to use of a two-litre, four-cylinder petrol engine
Other 7 Series models use six, eight and twelve-cylinder engines.
Despite its small engine, the 740e is still impressively quick.
0-62mph takes less than six seconds, and response is virtually instantaneous thanks to the electric motor
The electric motor alone can take the 740e up to beyond 80mph
It's also on hand to provide a welcome boost when you're overtaking or accelerating on the motorway
To make the most of the 740e's hybrid capabilities you'll need to keep the lithium ion battery pack fully charged.
This can be achieved overnight with the supplied charging cable.
In theory, up to 134.5mpg is possible
The long-wheel base 740Le xDrive version is slightly less economical...
...but still promises in excess of 100mpg
