Subaru Outback
2.5i Lineartronic petrol AWD CVT
August 2023: The result of this car has been updated. Previously reported Ammonia (NH3) values were incorrect owing to a technical error with the equipment at the test laboratory and a correction has been applied.
Subaru's AWD Outback is a large family car with well-known all-rounder capabilities. The newest version comes with a 2.5 litre naturally aspirated boxer engine. The high power demand of this vehicle type in combination with no pressure charging or powertrain electrification lead to high consumption figures, which are also reflected in the poor greenhouse gas emissions performance. The vehicle's mass and utility value, however, is no excuse for the pollutant control difficulties the car experiences at high load testing – here made obvious in the BAB130 Highway Test. On the plus side, pollutants are controlled better than average under moderate power requirement, including standard real-world driving with cold powertrain start. NOx emissions are always kept low, even on the motorway. Overall, with a final result of only 1½ Green Stars, the Outback's environmental behavior needs to be improved in order to suit better its legendary off-road capabilities or its 5 star Euro NCAP safety performance.
