Sport Plus higher rev per gear compared to comfort mode. If using it as automatic the gear does usually shift beyond 6. It uses more fuel to create pops and bangs of the exhaust
In my experience the only way to make the fuel consumption of Sport Plus to come close to comfort is to drive in manual mode with paddle shift where you could control the gearing to some extent but you would still not be able to higher basal rev usually below 50mpg.
