Nevertheless the team persevered and fitted a standard 1.5-litre Climax 4-cylinder engine, mounted at a slant to make room for the front driveshaft. In addition the driving position was moved slightly off-centre to accommodate the gearbox and rear driveshaft to the driver's left hand side.

Meanwhile, advances in wing and tyre technologies negated any advantage to compensate for the extra weight and complication of their 4WD transmission systems compared to their rear-wheel drive contemporaries. Furthermore, virtually every driver who drove the cars hated the way they handled.

It was apt, given its designer, that the P67 itself was later used extensively in hillclimbs, as the
