1971 Jaguar E-Type Series III 2+2
In 1971, the Jaguar E-Type Series III introduced the V12 engine to the model. This raised the car’s appeal on paper by having much more exotic specification. Jaguar called it the “Ultimate Cat” and advertised the car’s inherent smoothness and absence of engine noise.
Both the Coupe and Roadster were built on the longer 2+2 chassis which meant the Borg Warner automatic transmission was available on all V12 xkes.
Weighing in at 680 lbs (300 kgs) the small block V12 displaced 5.3 liters and produced 314 horsepower. It was an all-new sohc V12 utilizing four Stromberg carburetors.
Much of the E-Type structure had to change to accommodate the new V12 including widening of the engine subframes and a wider track. This included using the Saloon rear subframe assembly which added 3.25 inches of track.
Visually the car had a new eggcrate grill, wheel arch flares, four exhaust tips. Mechanical upgrades included larger brake discs and a larger fuel tank.
Production of the Series III coupe reached 7,299 cars.

Auction Sales History
1972 Jaguar E-Type Series III 2+2 Coupe – sold for $30,800 Ideally suited for touring, this Jaguar features both power steering and factory air conditioning, a perfect combination with the larger 2+2 body style. The car has been driven, though its original leather upholstery and carpets are quite presentable. The engine bay is clean, however, it is not detailed and reflects regular use. Equipped with the very desirable four-speed manual transmission, optional chrome wire wheels and red exterior with biscuit leather interior, it would be a car perfect for Jaguar Club driving events.
