Catalogue information
The 1.6 CDVi diesel engine originated from the partnership between Ford and PSA and thus carries Peugeot-Citroën genes. However, Ford has also had its say in the development phase. The German-American manufacturer insisted on having an overboost function of the engine as on its TDCi's. Specifically, the turbo pressure is slightly increased - but only in the top two gears - to provide some extra Newton meters for a few seconds: 20 in the case of the 1.6 CDVi, bringing the maximum torque to 260 Newton meters. The power also turns out to be remarkably good considering the cylinder capacity: 109 hp is available from 4,000 rpm, making the specific power to 70 hp per liter. Nevertheless, the CDVi has two minor flaws: its noise reduction could be better and when you press the accelerator you systematically experience a shock. In theory, a small cylinder capacity, a high injection pressure (1,600 bar) and a high specific power (69.9 hp per liter) guarantee low consumption. This appears to be correct for the CDVi, because its standard consumption is 5 liters per 100 km, despite the dimensions of the Mazda 3. Practice confirms this: on a route consisting of major roads, highways and a good dose of traffic jams in city traffic, we reached after all, a general average of 6.9 liters per 100 km.
