The Cincinnati Concours d'Elegance has established the practice of honoring an outstanding collector with a special exhibit. For its 47th incarnation the concours chose Jeff Lane, owner of the Lane Motor Museum in Nashville, TN (https://www.lanemotormuseum.org/). This is a must see museum as it boasts a large collection of European vehicles as well as an impressive assortment of micro cars and a number of vehicles you won't see anywhere else. As an example, here is a 1932 Helicorn Propeller Car. This car is actually propeller driven through its 1000 cc four cylinder Citroen engine. It has rear wheel steering and, believe it or not, is road legal in its native France.
A slightly more conventional design is this 1960 BMW 700 coupe. Powered by a 697 cc air cooled flat twin engine that generated 40 horse power. This low cost car is often credited with helping BMW survive following World War II.
Over nine million 2CVs were manufactured by Citroen in France between 1948 and 1990. Yes, the cars did come with a body as this one is in the midst of a restoration. They were driven by a 602 cc flat boxer two cylinder engine that cranked out 32 horse power.
The Czech vehicle manufacturer Tatra began operations in 1850 making it the third oldest continuous vehicle manufacturer in the world. This is a 1958 T-603 Saloon. The cars were made from 1957 until 1975 and only members of the Communist party were allowed to buy them. The car has a 3.5 L V8 engine in the rear.
The first rotary powered car manufactured by Citroen was this 1970 M-35. Only 267 were ever produced and the factory tried to buy them all back. Sixty survived and this is the only one known to be in North America. It has a 497.5 cc rotary engine that produces 49 horse power.
This is 1964 Peel P50. This British micro car is the smallest passenger car in the world. It has a single cylinder engine and weighs in at 250 pounds. While it has three forward gears there is no reverse. What there is, though, is a handle in the back for people ti pick it up and move it themselves.
On a more conventional note here is a 1955 MG TF which I believe was the very first car Jeff Lane ever bought and restored. These cars were heavily exported world wide following the end of World War II. They have a 1250 cc inline four cylinder engine that churns out 57.5 horse power.
This 1957 Aurora Safety Car was designed and built to be the safest car in the world. Built by Branford, CT based Juliano Custom Cars it sported such features as seat belts, puncture proof tires, side impact protection, a padded dash board, and even a roll cage. It does have a 264 cubic inch V8 engine that makes 143 horse power. This is the one of one concept and cost $300,000 in 1950s dollars. Safe it might be but it's not going to win any beauty prize.
