The Nissan Qashqai 1.5 dCi is known for its efficient fuel consumption, making it a popular choice among diesel SUVs. Official combined fuel economy figures for the 1.5 dCi (particularly from model years 2017-2021) reach as high as 61.9 mpg (UK), with city driving rated at about 56 mpg and highway driving up to 65.4 mpg[2]. This equates to a potential total range of approximately 898 miles on a full tank in ideal conditions[2].
Manufacturer claims for the 1.5 dCi are often around 60 mpg (UK), with CO₂ emissions as low as 99 g/km for some trims[5]. However, real-world fuel consumption can vary. Long-term tests and owner reports suggest that a realistic expectation for daily driving is an average of 48–52 mpg (UK), with careful motorway driving occasionally reaching 55–60 mpg[3][5].
For the newer 1.5-litre dCi 115 DCT (automated version), official figures under WLTP testing put fuel economy at up to 52.1 mpg (UK)[4].
Actual results depend on driving style, traffic conditions, maintenance, and whether the car is predominantly used in urban or motorway environments. Owners generally report that, even in winter or with predominantly city use, averages above 50 mpg can be achieved[3].
