Ecurie Ecosse, a tuning company that was a former motor racing team from Scotland founded in November 1951 by Edinburgh businessman and racing driver David Murray and mechanic Wilkie Wilkinson,  has relaunched the nearly forgotten 1966 Jaguar XJ13 prototype racer.

The new version, known as the Ecurie Ecosse LM69 Sports Car, is a road-legal sports car. The original racer, which was originally designed to compete against Ford, Ferrari and Porsche in the 1969 Le Mans 24 Hours race, has been updated as an “ideal” of what the Jaguar XJ13 was intended to be. Unfortunately, the first XJ13 project was cancelled due to a lack of funding as other Jaguar projects were prioritized.

The new model has been developed in aluminum and composite materials. It also follows the general principles of the Jaguar XJ13 period with design features and technology that appeared in motorsport prior to 1969. The LM69 is fueled by a quad-cam, naturally aspirated 5.3-litre V12 engine and fed by a conventional mechanical injection system. The engine will be manufactured to the same specification as the 5.3-litre V12 in the original XJ13. The engine will deliver 502bhp, 517Nm of torque and a top speed of 177mph to the sports car.

The 5.3-litre V12 can also be equipped with programmable fuel injection and electronic ignition for enhanced performance and dependability. Also, potential buyers can request a tuned version of the same V12 engine with capacity incremented to 7.3-litres.

The LM69 is fiercely loyal to the original model’s style, though some modern features have been added, such as a curved glass engine cover, a permanent roof and a large rear wing. The Ecurie Ecosse model also includes broader wheels and tires than the original 1966 Jaguar XJ13, as well as a pair of powerful dive planes for improved handling.

In September, the Ecurie Ecosse LM69 will debut at the Concourse of Elegance at Hampton Court Palace in London. The new model is available to order now at an estimated price of £750,000, though production will be restricted to just 25 units, which is in line with the 1969 FIA homologation regulations. Each model will be hand-built in the West Midlands by top British craftsmen.
