Alfa Romeo Stelvio Quadrifoglio review - MPG and running costs
That V6’s thirst is not a strong point; expect barely more than 20mpg in normal driving
Alfa Romeo’s official MPG rating is 23.9mpg on the WLTP cycle, a figure that’s difficult to match in the real world. Over the course of more than eight months with one on our Fast Fleet, we managed an average of 21.3mpg, but found on limited occasions it would rise to closer to 30mpg on gentle motorway cruises.
Over the course of nearly 18,000 miles it also needed an oil change, which cost just over £300, and two sets of rubber (one being winter rubber, admittedly) that cost somewhere around £900 for a set. The Pirelli P Zero standard rubber performed well, but the aggressive geometry set-up and low wear rating will make tyres an expensive enterprise, especially if you upgrade to the new 21-inch options.
There are also some question marks over the long-term reliability of the power and drivetrains, as with Stelvios now coming to the end of their warranty period, dealership workshops have started murmuring about issues surrounding the turbochargers and differentials. Still, given the old Selespeed transmissions and electrics of previous generations of Alfa Romeos this shouldn’t come as a surprise.
The extreme stance of those tyres will also make regular touch ups around the lower surfaces a requirement if you wish to keep it free of excessive stone chips. The aggressive geometry also will need constant attention, as the steering operates on a knife-edge, something only exaggerated by the quick and light steering rack.
