At CAR, we take each vehicle we test on a standard, mixed-use fuel route of 100 km (comprising of urban and motorway sections) to gather data on its "real-world" fuel consumption. Listed below are the 10 most fuel-efficient cars (measured in litres per 100 km) of the 75 vehicles we tested in 2019...

8=. Toyota Corolla Hatch 1,2T Xs: 5,90 L/100 km (claimed: 6,10 L/100 km)

The Toyota Corolla Hatch is an impressive midsize challenger, with its 1,2-litre turbocharged four-pot producing 85 kW and 185 N.m of torque. It also proved fairly frugal.

8=. Suzuki Vitara 1,4 Turbo GLX 6MT: 5,90 L/100 km (claimed: 5,80 L/100 km)

Sporting Suzuki’s 1,4-litre Boosterjet mill (the same unit found in the plucky Swift Sport), the Vitara churns out 103 kW and 220 N.m, the latter from a low 1 500 r/min, which is sent to the front axle via either a six-speed self-shifter or manual ‘box with the same number of ratios, which features here.

8=. BMW i8 Roadster: 5,90 L/100 km (claimed: 2,10 L/100 km)

The futuristic-looking i8 Roadster’s hybrid powertrain produces a combined 275 kW and 570 N.m. Roof down, the i8 is even more appealing.

5=. Suzuki Ciaz 1,5 GLX MT: 5,60 L/100 km (claimed: 5,50 L/100 km)

A second Suzuki makes its way onto the list. The Ciaz employs a 1,5-litre four-cylinder naturally aspirated petrol engine, producing 77 kW and 138 N.m of torque, and, like the Vitara Turbo, used only 0,1 litres more than its claimed figure.

5=. Datsun Go 1,2 Lux: 5,60 L/100km (claimed: 5,20 L/100 km)

Weighing 864 kg, the Datsun Go uses an atmospheric 1,2-litre petrol engine with modest outputs of 50 kW and 104 N.m to lug it around. Available only in five-speed manual when tested (a CVT option has now been added to the local line-up), the city car managed a 5,60 L/100 km figure.

5=. Audi A1 Sportback 35 TFSI S tronic: 5,60 L/100 km (claimed: 5,10 L/100 km)

Arguably the sweet spot in the A1 range, this Python Yellow 35 TFSI’s 1,5-litre turbo four sipped only 0,5 litres more on our standardised 100 km fuel route than what the Ingolstadt brand claims.

4. Mahindra XUV300 Diesel W8 Manual: 5,30 L/100 km (claimed: 5,88 L/100 km)

Employing a peppy diesel engine with 300 N.m of torque on tap from 1 500 N.m, the Mahindra boasts a fuel-route figure nearly 0,60 L/100 km less than claimed. Only a six-speed manual gearbox is on offer.

3. Volkswagen T-Cross 1,0 TSI 85 kW Highline DSG: 5,20 L/100 km (claimed: 5,30 L/100 km)

The small crossover to beat, the T-Cross was met with great enthusiasm when launched in the local market. Tested in December 2019, this Highline model’s 1,0-litre turbo triple directs 85 kW and 200 N.m to the front rubber via a seven-speed dual-clutch transmission.

2. BMW 320d Steptronic: 5,10 L/100 km (claimed: 4,50 L/100 km)

Returning a consumption figure just above the 5,0 L/100 km mark, the Bavarian automaker’s entry-level diesel 3 Series is both dynamic and frugal.

1. Mercedes-Benz C220d 9G-tronic: 4,90 L/100 km (claimed: 4,40 L/100 km)

 

A more comfortable proposition than the BMW, the refreshed C220d clinches top-spot with a tested fuel consumption figure of just 4,90 L/100 km.
