Character

EW7 1.8

"307/406/Xsara. EW family — aluminum block, 16V. Timing belt. Oil consumption at high mileage. Thermostat housing. Adequate performance. Less common than 1.6 or 2.0."

TU3 1.4

"15 million TU engines made. Simple cast iron block. Timing belt (not chain). Head gasket can fail on very old units. Incredibly cheap to maintain. 206/207/C3 workhorse. Over-engineered for what it does."
