The £99,040, range-topping i5 M60 xDrive adds an electric motor on the front axle for four-wheel drive.
With up to 592bhp and 605lb ft in Sport mode, it has a claimed 0-62mph time of 3.9sec and, in combination with an M Launch Control and an M Sport Boost function, a top speed limited to 143mph.
Both EVs use an 81.2kWh lithium ion battery, with the i5 eDrive40 offering a range of between 300 and 348 miles and the M60 between 277 and 314 miles.
Both can charge at up to 205kW. BMW has also confirmed the petrol-electric plug-in hybrid 530e Touring will be sold in the UK from July in rear-wheel-drive guise, although a four-wheel-drive version will also be available overseas.
The 530e Touring pairs a turbocharged 2.0-litre four-cylinder petrol engine with an electric motor for 295bhp and 331lb ft. Its 19.4kWh battery gives an EV range of up to 60 miles.
The 5 Series Touring will also be launched with two pure-diesel options, but they are not destined for the UK. The mild-hybrid 2.0-litre unit develops 195bhp and 295lb ft in the rear-wheel-drive 520d and four-wheel-drive 520d xDrive – the former offering claimed consumption of 45.6-49.6mpg.
A 3.0-litre six-cylinder diesel, producing 282bhp and 479lb ft in the 540d xDrive, delivers 0-62mph in 5.4sec and up to 48.7mpg.
