However, while these cars were moderately successful and had a good reputation, Ford could not match Holden's price, so sales suffered. One of the reasons for the price difference was the higher cost of imported parts, which were subject to an import tariff. Ford also assembled Canadian-sourced Ford V8 models, but these cars were in a higher price category, putting them out of reach of the average buyer. Hence, Ford decided to commence local production of a Holden challenger. Initially, they intended to produce the Zephyr, Consul, and Zodiac, using expensive dies they would need to purchase from Ford of Britain. However, during a visit to Ford headquarters in Detroit in 1958, they were shown the new Falcon, which was being prepared for its United States launch. Immediately, the executives were attracted to the new car- it was about the same size as Holden, but it was low, long, wide and modern. The width allowed it to accommodate six people, and a two-speed automatic transmission was available. Besides all this, Ford Australia felt they had more experience building North American cars. Hence, they decided to make Falcon their new Australian car. In 1959, Ford built a factory at Campbellfield, a suburb of Melbourne, for local production of the North American Ford Falcon. The factory was designed in Canada, and had a roof that would facilitate dispersal of snow, notwithstanding the fact that snow does not usually fall in Melbourne. The first Falcon sold in Australia was the XK series, introduced in September 1960. It was initially offered only as a four-door sedan, in both Falcon and Falcon Deluxe trim levels. The XK was essentially a right-hand drive version of the North American model, although local country dealers often included modifications such as heavy-duty rear suspension (five leaves) and larger, 6.5 by 13-inch (17 by 33 centimetre), tyres. The steering was light and the ride surprisingly good, on well-paved roads. The Falcon's "king-size" drum brakes actually had less lining area than the Zephyr's, but they were stopping a car that was over lighter, and so were adequate. Whereas the North American model used an "economy" 3.10 to 1 rear-axle ratio, the Australian Falcon was built with a 3.56 to 1 ratio, which better complemented the torque characteristics of the engine, yet still allowed a reduction in cruising rpm when compared with the Zephyr. The station wagon, added to the range in November 1960, lacked the American version's extended rear overhang due to concern that the back of the car might scrape on rough roads and spoon drains.
