Made of aluminium in the barchetta style, it was devoid of road-going items such as carpets, weather equipment and exterior door handles.

[3] Testing by Norman Dewis at MIRA after the race proved that the overheating was caused more by the revisions to the cooling system than by the altered aerodynamics: the water pump pulley was undersized, so it was spinning too fast and causing cavitation; also the header tank was in front of the passenger-side bulkhead, far from the radiator, and the tubing diameter was too small at 7/8 inch.

The main drawback of the new body shape was that it reduced downforce on the tail to the extent that it caused lift and directional instability at speeds over 120 mph (193 km/h) on the Mulsanne Straight.

[4] This time the body was in thinner, lighter aluminium and the original twin H8 sand cast SU carburettors were replaced by three DCO3 40mm Webers, which helped boost power to 220 bhp (164 kW).

Philip Porter mentions additional changes: Further weight was saved by using a rubber bag fuel tank ... lighter electrical equipment and thinner gauge steel for some of the chassis tubes ... [T]he most significant change to the cars were the triple Weber carburetors and [switch to] disc brakes.

1954, the C-Type's final year at Le Mans, saw a fourth place by the Ecurie Francorchamps entry driven by Roger Laurent and Jacques Swaters.

In an article in the 11 June 2003 issue of Autocar magazine ("Slick Cat Jaguar", p. 70) the value of a "genuine, healthy" C-Type is estimated as £400,000, and the value of the 1953 Le Mans winner is about £2 million; replicas are available from a variety of sources from £40,000.
