You are driving a motor vehicle with a manual gearbox. How can you reduce the fuel consumption of your vehicle?

You answered correctly. Fuel consumption can be reduced by both shifting up to the next gear early and by driving in an anticipatory manner to avoid frequent speed changes. Early upshifting lowers engine RPM, which makes the engine run more efficiently and use less fuel. An anticipatory driving style means looking ahead and adjusting your driving to minimize unnecessary braking or acceleration, which also saves fuel. Driving at a high engine speed increases fuel consumption and should be avoided for economical driving. Using these techniques helps you drive more efficiently and use less fuel.
