Explanation: In this context Volllast = Full throttle, no doubt.
Two versions of the sentence:
A low-RPM driving manner with full-throttle intervals kept to a minimum would significantly reduce average fuel consumption, particularly with turbocharged gasoline engines.
or: ... improve fuel efficiency...
Particularly with turbocharged gasoline engines, actual gas mileage can be significantly improved through a relaxed, low-RPM driving manner where full-throttle intervals are kept to a minimum.
Turbocharging improves overall fuel efficiency, as it ensures more complete combustion of the fuel in the combustion chamber. At high revs/full throttle, however (in the so-called high supercharging zone), fuel efficiency deteriorates compared to a normally aspirated ICE. Actually, full throttle is always inefficient in terms of fuel consumption, but this seems to be more pronounced in turbocharged engines.
In short: if you're driving a turbo, your gas expenses would normally be lower - unless you're in the habit of holding your right foot down to the floor. Been there, done that... ;)
