1.6 EcoBoost vs VR6: which engine is more reliable?

According to our risk index, the VR6 carries less risk than the 1.6 EcoBoost: 50/100 versus 59/100 (both high risk). The 1.6 EcoBoost has 3 documented serious faults, the main one being «Cracked cylinder head from overheating, with fire risk»; the VR6 has 1 documented serious fault, the main one being «VR6 timing chain and tensioners».

Is the 1.6 EcoBoost reliable?

It is a turbocharged direct-injection four-cylinder that Ford used between 2010 and 2018 as a mid-range step across much of its European line-up, and which Volvo sold under its own T3/T4 designations. Its most serious fault is overheating caused by a loss of coolant circulation that can crack the cylinder head and cause a fire: Ford has recalled cars in South Africa and in the US/Canada, although we have not confirmed an equivalent campaign in Spain.^[1][2][3]

Is the VR6 reliable?

Its best-documented faults are the timing chain, with tensioners on the 12-valve versions and stretching on the 3.2 (R32, A3 8P, TT, Cayenne), and, to a lesser extent, the cooling system of the 12-valve versions. The 3.6 FSI comes out of the sources better than the 3.2.^[4][5][6]
