New BMW 5-series revealed - Telegraph The petrol line-up also meets the new emissions standard ahead of schedule, including a new 4.4-litre twin-turbocharged direct-injection V8. Powering the 550i saloon, Touring and Gran Turismo, it develops 449hp and 479lb ft of torque, achieves 32.8mpg and emits 199g/km of CO2. That makes it more powerful and more fuel-efficient than its predecessor. As well as the new and revised engines, there are subtle tweaks to the 5-series' styling. All saloon and Touring models have additional contour lines around the BMW kidney grille and a new-look lower air intake. The door mirrors now house indicator repeaters and the tail lights incorporate LED strips. All models have Xenon headlights with LED lights available as an option. There are mild changes to the look of the 5-series Gran Turismo, too, with a new front air intake, an extended tailgate and a chrome strip in the rear apron. The Gran Turismo is more practical than before, with luggage capacity increasing by 60 litres to 500 litres. Equipment levels have been improved. All saloon and Touring models are now supplied with satellite navigation as standard. Four-cylinder Gran Turismo models continue to come with satellite navigation while six-cylinder models now have the more sophisticated "Professional Navigation" system. All 5-series are equipped with BMW Emergency Call, which contacts the emergency services with the car's location in the event of an accident. Optional safety systems include Driving Assistant, which combines Lane Departure Warning and Front-end Collision Warning, and will automatically apply the car's brakes if required. Prices for the 520d SE saloon start from £31,530 (an increase of £1,100), while the Touring costs £33,855 (up £900). Order books are open now, with the customer deliveries starting in September.
