ZAFIRA is powered by a new-generation 2.2-litre ECOTEC DOHC 16-valve four-cylinder engine that develops 108kW of power at 5800rpm and 203Nm of torque at 4000rpm. In an effort to minimise fuel consumption, the all-alloy unit features optimally shaped combustion chambers, a compression ratio of 10:1, minimal friction losses in the cylinder head and an advanced engine management system. Official figures for the automatic version point to 10L/100km on the city cycle and 6.6L/100km on the highway. It uses standard unleaded fuel and complies with the tough Euro 4 emission standards not due in Europe until 2005.
