Proton claims the X50 returns a fuel consumption figure of 6.4-litre/100 km for the range-topping 1.5 TGDi Flagship variant. But what’s the real-world fuel consumption like? We tested the Proton X50 to find out.

As per usual, all tyres were inflated according to the manufacturer's recommended tyre pressure. Then the Proton X50’s 45-litre fuel tank was brimmed.

Air-conditioning was set at 22 degrees Celsius in automatic mode. Driving behaviour was normal, without aggressive throttle inputs or hypermiling. Driving mode was kept at normal mode.

After driving for 71km in a mix of 60% city and 40% highway driving, a calculated fuel consumption of 10.2-litre/100 km was obtained. Admittingly, it is on the higher side. Interestingly, the onboard computer showed an average fuel consumption figure of 8.4-litre/100 km.

To recap, all variants but the Flagship are powered by a 1.5-litre multi-point injection (MPI) turbocharged 3-cylinder engine that produces 150 PS and 226 Nm.

The Flagship gets direct-injection (TGDi) which bumps output to 177 PS and 255 Nm. Both engines are mated to a 7-speed DCT automatic transmission.
