In February 1988, the 2.5 L engine was enlarged to 2.7 L, the Maestro-derived instrumentation had been changed to gauges sourced from a different component-builder (losing the oil pressure gauge and voltmeter in the process) and build quality had vastly improved. A budget version of the 800, using an eight-valve (as opposed to the usual 16-valve) version of the O-series engine was introduced. This was called M8, it differed from the O-series engine as the water pump was driven by the timing belt. Though this budget model was short-lived.
