context_page_description: The Panhard CD is a car designed by Charles Deutsch and built by Panhard from 1963 to 1965. The CD was named for Deutsch and is considered a continuation of the line of Panhard-powered vehicles built by Deutsch-Bonnet. The car was the production version of the CD Dyna that raced at Le Mans in June 1962.
context_section_description: After going to Le Mans in 1963 with a car powered by a DKW two-stroke three-cylinder engine, Deutsch returned in 1964 with a new ultra-streamlined Panhard-powered car called the LM64. Two cars were built; LM64/1 and LM64/2. These cars retained the central backbone chassis from the production Panhard CD, revised by Jean Claude Haenel. The transverse leaf spring in the front suspension was replaced by coil springs.
  Once again Romani took the lead shaping the body. He produced a shape with completely covered headlamps, smooth sides with front and rear wheel spats and a smooth underfloor with a section towards the rear of the car shaped like a diffuser in an early use of "effet de sol" or "ground effect" to produce down-force. A more obvious feature was the two large vertical fins at the rear for stability at high speeds. The result of this work was that the LM64s had a drag coefficient even lower than that of the Panhard CD, with a  of just 0.12.
  Due to safety concerns cars with engines smaller than 1 litre were not allowed to run at Le Mans beginning in 1964. To overcome that restriction the engine in the LM64s received a Sferma supercharger along with other changes that included twin-iginition and dual Zenith carburetors. By applying the 1.4 multiplication factor for engines with forced-induction the effective displacement of the 848 cc Panhard engines rose to 1187 cc making the car eligible for the under 1200 cc class. Power output was up to 58.2 kW (78 hp). The transaxle used was a ZF 5-speed unit.
