MK4 Cortina - Performance and Economy!

New Cortina has a comprehensive engine line-up, with a choice of 4 power units, including 2 special economy versions - 1300 and 1600 cc. All the engines are established Ford designs which have been tried and tested in other models and shown to be ruggedly reliable. Fleetowners know and respect these engines and appreciate the easy-servicing characteristics, combined with widespread availability and low cost of service parts.

The charts show the performance figures and engine availability, and you'll see that there's an engine to suit every buyer's needs. Starting at the top of the range, the 2 litre OHC engine with twin-venturi carburettor has all the power needed for sparkling acceleration and a top speed well into 3 figures. This unit is available in the GL, S and Ghia models. For a balance between performance and economy, the 1600cc OHC engine with single-venturi carburettor is available in L and GL models and gives good acceleration, a top speed over90 mph, and a touring fuel consumption figure of around 34 mpg. Then, if outright economy is of paramount importance, the Cortina and Cortina L models have a choice of 2 special economy packages, either 1300cc or 1600cc. This is the first time that an economy version of the 1600cc engine has been offered, and like the 1300 economy engine, its carburettor and inlet manifold have been carefully recalibrated to give optimum economy and driveability in conjunction with revised overall gearing.

Many vehicles spend up to a third of their working lives either warming up after a cold start or idling in heavy traffic, and it is in these conditions that regular carburettors tend to be least efficient. Using technology derived from gas turbine dynamics, Ford engineers developed the Sonic Idle system which, by dramatically improving fuel atomisation, enables steady stall-free idling to be obtained on much leaner air/fuel mixtures. Fitted to all single venturi engines, the Sonic ldle carburettor enables the choke to be dispensed with sooner after a cold start, eliminating unnecessary fuel wastage. And on short journeys, this can result in savings up to 15%. All four engines incorporate ballasted ignition coils for quick-fire starting and all are fitted with alternators and lightweight low-maintenance batteries. Improved ignition switches and electrical connections give even better reliability and durability. A special cassette-type water pump seal has been developed and this is incorporated in every new Cortina engine. New improved engine mounts are also fitted to all new Cortinas.

To meet European exhaust emission regulations, all Cortina carburettors are fitted with "tamperproof" seals to help ensure they keep their tune. And, in keeping with the anti-pollution aims of lower-lead content petrol, all the engines have been calibrated to operate satisfactorily on low-lead petrol containing only 0.15 grams per litre of lead additive. The engines drive through either the world-renowned Ford 4 speed manual gearboxes or the sophisticated Ford C3 automatic transmission. Both systems have been praised by many thousands of satisfied owners and are still fully competitive with anything offered by competitive manufacturers. Careful attention has been paid to the relationship of engine, drive shaft and differential to minimise vibration. This has been achieved by lowering the front of the engine and re-aligning the drive shaft to reduce the angles through which the universal joints-operate.
