MPG and running costs
The official MPG figures for the Q8 suggest that over 40mpg will be achievable on a combined run. With a careful right foot that may well be possible, but we only managed low-30s during our drive. That said, even our economy results are impressive for an SUV that weighs more than 2000kg.
The Q8’s huge wheels may not have a detrimental effect on the car’s comfort levels, but it does on the cost of tyres. The 285/45 R21 Hankooks that are standard on the S-line are over £200, while tyres that size from other brands are at least twice as much. The 285/40 R22 Continental Sport Contact 6 tyres on the Vorsprung are over £300 each.
