Elva Chassis

C Sports Race


Elva (a name derived from the French "Elle va" = "She goes") was a successful car constructor in the late 1950s and early 1960s, and was certainly a force Lotus drivers had to reckon with as the well built and efficient sports racers proved more than a threat to Colin Chapman's production.


Elva produced 69 Mk7s between 1963 and 1965. The car shown on the right is the 13th. It was built in 1963 and delivered to Swiss racer Sidney Charpilloz. The photos and information below are from an ad seen on on July 26, 2004.
