When looking at a new car, fuel efficiency is an important factor to consider as fuel costs climb ever higher. You will save more money each time you travel if your vehicle is more economical. Miles Per Gallon (MPG) measures how many miles a car can travel on just one gallon of fuel. Fuel economy will vary depending on who's behind the steering wheel, as everyone has different driving styles.
When it comes to fuel economy over the years, diesels are known for being the best option regarding MPG for longer journeys, with petrol-engined cars having to play second fiddle. However, these days, plug-in hybrids dominate fuel economy figures, with turbochargers and electric technology helping to make petrol and diesel engines more efficient than ever. The Mercedes GLE 350de, for example, can manage well over 200mpg due to its ability to run solely on electric power for upwards of 50 miles.
