Background
By the time the Series III E Type hit the roads in April 1971, the range had had a full ten years to cultivate a well-earned place in the hearts and minds of the discerning motoring enthusiast, especially in the important North American market. North American sales were critical to the E Type and, hence, Jaguar with well over 50% of the car’s production being shipped across the Atlantic.
With the Americans increasingly demanding V8 propulsion, preferably displacing as many cubic inches as possible, the mere six pots of the Series I and II’s were starting to lose their lustre a little. No surprise, then, that the Series III debuted the 5,343cc V12 SOHC Hassan and Mundy designed engine, breathing freely through quad 1.75-inch Zenith / Stromberg carburettors. The engine was originally designed for the ill-fated XJ13 Le Mans car and was de-tuned and reconfigured for road use losing an overhead camshaft in the process.
The engine still delivered a competitive 266 bhp, however. This prodigious power paired with Malcolm Sayer’s super slippery shape made for a truly performance orientated offering. A contemporary road test of a manual OTS was able to record a highly impressive 6.4 second 0-60 mph time and roar on to hit 146 mph. A truly eye-widening performance for the time. Better still, this class leading performance was available at a surprisingly modest price point. At launch in 1971, a V12 OTS unadorned with extras retailed at £3,123 or the equivalent of 108 times the period’s average weekly wage in the UK. Using that same measure today, this equates to around £60,000.
The new V12 engine was the headline, but it wasn’t the only change, of course. The track was wider to accommodate 6J wide wheels and, as a result, the wheel arches were subtly flared. Power steering became standard on all models as did servo assisted brakes all round. The Series III did without the Fixed Head Coupe of the earlier Series, with the tin top now only available in the longer wheelbase 2+2 Coupe. The deeply desirable OTS configuration remained, of course. The success of the Series III translated into a relatively large production output of 15,287 cars in total. However, only around half of the total were open topped cars.
