Built in 1970, towards the end of the production run - this E-type is one of the last Series II roadsters built before the introduction of the V12 powered Series III. The engine was the same 6 cylinder XK engine that was originally introduced in 1948 in the XK120, although it has grown from the original 3.4 litres to 4.2 litres and the fuel is provided by 3 carburettors instead of the original 2 SUs.  


Series I cars had fully enclosed headlamps but these were changed during 1967/68 to comply with US safety regulations. The rear lights were restyled at the same time. Interior changes meant the door handles were recessed and rocker switches replaced the toggle switches to meet US safety legislation.


The car is an original UK Right Hand Drive car built to UK specification, fitted with the 4.2 litre version of the famous six cylinder Jaguar XK engine. It is equipped with three, 2 inch SU carburettors and free from the emission control equipment that was fitted to the US specification twin Stromberg cars.  Jaguar claimed that the E Type developed 265 bhp but it is more generally believed to be around 250 bhp. The US specification cars had about 30% less power so any Americans who have driven an E-Type in the USA tend to be surprised at the power of our British specification E-Type.  


We have replaced the chrome wire wheels with alloy copies of the racing wheels used on the Jaguar D-Types in the 1950's, supplied by Realm Engineering in Evesham. These wheels are 6 inch wide instead of the standard 5 1/2 inch wheels, allowing us to fit wider tyres. Most tyre suppliers have problems balancing wire wheels and they rarely get it right so the new alloy wheels result in a complete lack of any wheel vibration and a smoother and safer ride.




  • E-type Series I - from Spring 1961 to 1968       - 38,399
  • Series II - from December 1968 to March 1971 - 18,854  
  • Series III (V12) - from Jan 1971 to Dec 1974    - 15,283  




The rear half of the car is a steel monocoque with a space frame bolted to the front bulkhead. This space frame holds the front suspension, the engine and gearbox and carries the bonnet. The boot lid has no external handle, being opened by a lever behind the driver’s seat.  


History of DDT 343H:  

  Removable steering wheel from Superspoke

We have an extensive history file on the car right from its 1st service through to a major re-build about 15 years ago.  


In 2015 Jaguar Heritage finally started re-manufacturing new bonnets for SII E-Types (they had been making bonnets for SI and SIII for some time) so we bought a new bonnet and had the whole car re-painted.  To complement the paintwork we had the rear bumpers re-chromed before re-fitting them.  


In February 2016 we fitted a removable steering wheel mechanism to our E-Type.  The steering wheel can now be removed to help driver's enter or exit the car or if we are working under the dashboard or in the driver's foot-well.  A brilliant piece of engineering manufactured by Superspoke Steering Wheels.




  • Length 14ft 8in (4.45m), width 5ft 5.25in (1.66m), height 4ft (1.22m), weight 2,688 lbs, 24 cwts (1,206 kg).
  • Engine 4,235cc six cylinder XK engine with twin overhead camshafts and hemispherical combustion chambers. 
  • Develops 265 bhp at 5,400 rpm and 283lb ft of torque at 4,000 rpm.
  • The engine is fed by three SU HD8 2 inch carburettors mounted on a heated inlet manifold.
  • Contact breaker points gap (where fitted) 0.014 to 0.016 in  (0.36 to 0.41mm)
  • Spark plug gaps 0.025 in (0.64mm)
  • Servo assisted disc brakes on all four wheels with the rear brakes being inboard (near the differential not at the hubs).
  • Front suspension: independent by double wishbones and torsion bars, with telescopic shock absorbers and an anti-roll bar.
  • Rear suspension: independent by lower wishbones with radius arms and twin coil springs with shock absorbers, the drive shaft forms the upper link.
  • Steering: Rack & pinion with 2 1/2 turns lock to lock giving a turning circle of 39 feet. 
  • The original 16 inch wooden steering wheel, although adjustable for reach, tends to rub across the driver's knees, so it has been replaced with a smaller 13 inch wooden Motolita wheel.
  • Wheels: Knock-off 'D-Type' style alloy wheels fitted with 205/70H15 radial tyres.
  • Tyre pressures (pounds per square inch): Front 32, Rear 32.
  • 0-60 in 7.0 secs. 
  • Top speed 150 mph (allegedly – probably nearer 130).
