The Europa utilized a minimalist steel backbone chassis with a fiberglass molded body to achieve a strong body with less weight.
All Europas were mid-engine cars, which made them ideal for road races like Le Mans, where cornering ability is a must.
There were several different models of the Europa, including the Series 1, Type 47, Series 2, Twin Cam, and Special.
Although the Renault and Ford/Lotus engines left much to be desired in the raw power department, these cars were still quite fast due to their low weight and low drag coefficient.
This car handled so well during its time that many reviewers claimed it was the closest any average man could get to driving an F1 car. The design and 4 wheel independent suspension have been imitated to various degrees of success since then in many smaller cars that want to be mini racers. Even today, cars like the Tesla Roadster electric car owe much to these original Lotus racers.
These cars can be found at collectible auctions and on places like eBay. You can also find some parts on eBay.
