The Lotus 48 was a Formula 2 car based on a 1600cc Ford FVA-engine that was run around 1967. Famously, it was the car in which Jim Clark was killed. Apart from that unfortunate fact it was campaigned fairly succesfully in F2, taking several wins.
Lotus was active and competitive in Formula One racing from 1958 to 1994.
Lotus Elite - The Lotus Elite was an ultra-light 2-seater coupe, produced from 1958 to 1963.
Lotus Elan - The second Elan, released in 1989, was a technical tour de force but one that also defied Lotus 'performance through light weight' tradition, to its detriment.
Although single-seaters originally gave Lotus fits due to their having to adapt their fragile chassis to very high power to weight ratios, Team Lotus continued its on-track success in sports cars as Chapman continued to develop his engineering magic.
Lotus cars, though intentionally built sparingly, were not gimcracks.
The Lotus 29's combination of many 25 features plus a solid big block Ford engine was so far ahead of the traditional roadsters that it made the whole thing akin to shooting fish in a barrel.
