The first production models had rolled off the production lines on 2 December Unlike the first Escort which was developed by Ford of Britain , the second generation was developed jointly between the UK and Ford of Germany. Codenamed "Brenda" during its development, it used the same mechanical components as the Mark I. The estate and van versions used the same panelwork as the Mark I, but with the Mark II front end and interior.
At the time this amounted to the fairly typical story, told in paraphrased summary here: The Twin Cam proved to be an excellent platform for the competition machines in both touring car and eventually rallying guise, and the Escorts campaigned by the Ford works teams racked up wins around the globe, becoming an iconic symbol of plucky British racing prowess in the process. Ford promptly celebrated the win by creating a special edition of the car for the consumer market, called the Escort Mexico. Released in , it was sold alongside the more expensive and faster RS model, which was powered by a belt-driven twin-cam engine developed by Cosworth as opposed to the smaller-capacity push-rod unit found in the Mexico. Soon after production of the second generation Escorts began in late, Ford decided the Mexico name should be carried over to the new lineup of its Rallye Sport versions. Without the racing provenance of the RS that sat above it in price nor the Sport that was just below it, the RS Mexico was a great car that barely sold thanks to sales cannibalization from those two and a lack of visibility in motorsport. Only 2, examples are said to have been built between and , and those were only for the domestic UK market, making the Mk2 Mexico one of the rarer versions of the great sporting Escorts, in addition to a pretty potent one.
