1.5 VC-Turbo e-Power vs 1.8 TCe: which engine is more reliable?

According to our risk index, the 1.8 TCe carries less risk than the 1.5 VC-Turbo e-Power: 32/100 versus 36/100 (both moderate risk). The 1.5 VC-Turbo e-Power has 3 documented serious faults, the main one being «Safe mode due to battery controller calibration (loss of propulsion)»; the 1.8 TCe has 2 documented serious faults, the main one being «A110 oil pressure solenoid valve sticking in 2018–2019 cars».

Is the 1.5 VC-Turbo e-Power reliable?

There is still little reliability data: the three-cylinder 1.5 VC-Turbo only generates electricity and no mechanical faults are known in Europe. The documented weak points are in the e-Power electronics: battery campaigns and isolated cases of immobilisation.[1][2][3]

Is the 1.8 TCe reliable?

The 1.8 TCe (M5P) in the Alpine A110 and the Mégane R.S. IV has no documented endemic faults. What has been published are recalls for the A110: the oil pressure solenoid valve (2019) and the fuel pump (2021 and 2023). We have found no recalls or complaints about this engine in the Mégane R.S.[4][5][6][7]
