At CAR, we take each vehicle we test on a standard fuel route of 100 km (comprising urban and motorway sections) to gather data on its "real-world" fuel consumption. Listed below are the least fuel-efficient cars (measured in litres per 100 km) we tested in 2020...
5. Alfa Romeo Stelvio Quadrifoglio – 11,1 L/100 km (claimed: 9,0 L/100 km)
With its Ferrari-sourced twin-turbo 2,9-litre V6, the Stelvio Quadrifoglio proved to be quite a bit heavier on fuel than Alfa Romeo claims. Of course, the Stelvio is by no means the only performance SUV that appears on this list...
4. Range Rover Velar SVAutobiography Dynamic Edition – 12,5 L/100 km (claimed: 13,5 L/100 km)
Although modern in appearance, the Velar SVAutobiography keeps things old school with its supercharged 5,0-litre V8. Although its capable of sprinting from 0-100 km/h in an impressive 4,63 seconds, lugging around all that mass doesn’t come without a compromise on efficiency.
3. Lamborghini Huracán Evo LP640-4 – 12,7 L/100 km (claimed: 15,7 L/100 km)
Although not the largest engine here, the Huracán Evo is indeed the most powerful car on this list courtesy of its naturally aspirated 5,2-litre V10 engine. Interestingly, however, it proved to be significantly lighter on fuel than Lamborghini claims. And, as you may have already noticed, it's the only model on this list that is not a performance SUV.
2. Lamborghini Urus - 14,3 L/100 km (claimed: 13,6 L/100 km)
Yes, the SUV theme continues with the Urus and its twin-turbocharged 4,0-litre V8 petrol mill. Unlike the Huracán Evo above, Lamborghini's SUV wasn't able to best its claimed figure.
1. Jeep Grand Cherokee Trackhawk – 15,8 L/100 km (claimed: 16,8 L/100 km)
The Trackhawk’s position here should come as no surprise. Not only is it the heaviest vehicle on this list but its supercharged 6,2-litre V8 engine has quite a drinking habit. Regardless, our fuel-route figure interestingly beat Jeep’s claim by a full litre per 100 km.
