BMW 5 Series
520i M Sport petrol RWD automatic
Sustainability Rating: 2½ stars
Our verdict:
Tested here is the BMW 520i - a premium limousine equipped with a 2 litre turbo-charged petrol engine supported by a 48 V-mild hybrid system. Given its luxurious specification and relatively high unladen weight of 1,800 kg, the vehicle achieves an adequate score of 46% and collects 2 Green stars. The most challenging area of assessment are the greenhouses gases, where the car scores poorly due to the combustion of relatively high amounts of fossil fuel.
- The exhaust emissions control system keeps pollutants very low, providing minimal air quality impact. The tyre abrasion score is good, but brake abrasion reduction potential is limited. The production and fuel supply emissions slightly worsen the score.
- Fuel use is moderate but limits the sustainability scoring. Lab test measurement resulted in 5.6-7.8 l/100 km, while the mixed trip On-road test needed 5.7 l/100 km.
- Fossil fuel combustion drives high GHG emissions: the average direct propulsion GHG emissions are measured with 149 g CO2/km. The additional emissions from the other LCA phases further reduce the score.
Driving Experience
Our comments:
The Driving Experience evaluation of conventional vehicles focuses only on the performance in the section 'Consumption and Range'. The BMW 520i's estimated real-world consumption figures are seen as adequate in all conditions - warm weather and cold winter, urban, rural, highway and mixed driving scenarios. The consumption readings on the board computer display are very accurate.
