1.5 VC-Turbo e-Power vs 1.2 12V: which engine is more reliable?

According to our risk index, the 1.5 VC-Turbo e-Power carries less risk than the 1.2 12V: 36/100 (moderate risk) versus 57/100 (high 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 1.2 12V has 2 documented serious faults, the main one being «Timing chain stretch and tensioner wear».

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 1.2 12V reliable?

The 1.2 12V is a simple, low-power, naturally aspirated three-cylinder engine (54-70 hp), with two documented design faults: the timing chain tensioner, which can end up destroying the engine, and -on the Volkswagen Polo IV- a catalytic converter too close to the cylinder head that can burn the exhaust valves. Ignition coil failures are also common, and there are isolated cases of oil consumption and vibration.^{[4][5][6][7][8]}
