What Are The Top 5 Most Fuel-Efficient Cars Of 2021?
When you are in the UK market to buy a passenger car, you look for a few desirable features. For instance, you would want a vehicle that is cosy and easy to drive, have ample room for passengers and their stuff, and boast a range of safety, driver-assist, and tech features. But wait, how can we forget about the fuel economy rating of the vehicle? With so much fluctuation in fuel prices, it really helps to have a car with the best-in-class fuel economy figure. Today, we bring you the top 5 most fuel-efficient cars you can buy this year. We have considered a mix of petrols, diesels, and hybrids, so there is something for every motorist.
1. Skoda Octavia 1.0 TSI e-Tec SE auto – 56.5mpg

The Skoda Octavia hatchback would take you to places on a full tank that no other vehicle can go. However, for that, you need to select it with a 1.0-litre three-cylinder mild-hybrid engine delivering an estimated fuel economy of 56.5mpg.
Obviously, when you go for a mild-hybrid variant instead of a combustion-powered model, you have to compromise on performance. The hatchback generates only 110hp and 200Nm of torque, enabling it to hit 100 km/h (62mph) in 10.6 seconds and top out at 200 km/h. However, that is not sluggish by any means. It has enough oomph for most of your daily commutes. Of note, the Octavia 1.0 TSI e-Tech only comes fitted with an automatic transmission. The manual is available with the non-hybridised 1.0-litre petrol engine.
2. Peugeot 308 SW 1.2 PureTech Active Premium manual – 54.9mpg

The second one on our list of most fuel-efficient cars of 2021 is the Peugeot 308 SW returning up to 54.9 mpg. It is very impressive considering it doesn’t get assistance from an electric motor-generator as the Octavia does.
We have picked the most frugal option for the 308 featuring 1.2L PureTech generating 110hp and 205Nm of torque, delivering enough power to all your motoring needs. The good news is both the estate wagon and the hatchback have the same economy figure.
3. Skoda Octavia 2.0 TDI SE manual – 68.9mpg

Are you going after the most economical diesel family car on sale in the UK this year with the best value for money and practicality? Look no further than the Skoda Octavia 2.0 TDI manual. When we say value for money, we are talking about an infotainment system with Apple CarPlay and Android Auto, efficient Virtual Cockpit digital display, LED headlights, rear parking sensors with manoeuvre assist, and exceptional 600-litre boot space.
The 2.0 TDI is powerful enough to create 115hp and 300Nm of torque with a manual gearbox and 148hp with an automatic. With a 68.9mpg fuel economy figure, it is a perfect ride for motorway commutes.
4. Mercedes GLE 350de AMG Line Premium auto – 403.6mpg

The diesel-electric plug-in hybrid model of the Mercedes GLE comes with the highest fuel economy figure on this list. Although it is a big car with a powerful engine, it returns an extraordinary 403.6mpg.
According to Mercedes, the GLE hybrid’s 2.0-litre diesel mill and electric motor can churn out a maximum of 320hp and an enormous 700Nm of torque. Thanks to this massive power, the GLE plug-in hybrid can zoom to 100 km/h from a standstill in only 6.6 seconds. You have to pay a pretty penny for this beauty since the GLE 350de AMG Line Premium is a range-topping model in the lineup.
5. Audi A3 40 TFSI e-Sport auto – 282.5mpg

Doesn’t matter you like the plug-in Mercedes A-Class AMG Line or the Audi A3 40 TFSI e-Sport; both are rated at 282.5mph thanks to their almost similar footprint. Indeed, the A-Class offers a little more power than the Audi A30 40 TFSI e, but the latter is by no mean a slouch producing 204hp and 350Nm of torque. This power takes this family car from 0 to 100 km/h in 7.6 seconds.
