I'd seen the one that was in car shows and museums, but this is new to me.



....and I like it.

He tried to pitch it to U.S. automakers. No one was interested.
The Chrysler Airflow debacle had turned automakers against 'streamlining.'
The customer is never right.

Which is ironic considering the Airflow only had the appearance of being streamlined, without the actual streamlining that the prototypes had.

Volkswagen Auto2000


The 1981 Volkswagen Auto 2000 obtained 63 mpg city, 71 mpg highway, boasting a 0.25 drag coefficient, 53 horsepower diesel engine, and 1,716 lb curb weight[1].

Volkswagen's E80 diesel concept obtained even better fuel economy. Using a 51 horsepower supercharged 3-cylinder turbo diesel, the 1,540 lb Volkswagen E80 managed to obtain 74 mpg city and 99 mpg highway[1]. It had a 0.35 drag coefficient[1].

I'd bet that someone with the resources could get my 46 horsepower 45MPG Dasher into the sixties or seventies.

Don't car much about the Airflow but I really wish Chrysler had brought the Pentastar to production. They'd have filled a niche the VW Beetle had.

Again, in context for it's times, aerodynamic effort is more than implied.

Kinda small wheels for a car, but it's for sale.

1936 Labourdette Delage V12 Vutotal Aerodynamique

"Born in Béarn in 1890, Jean ANDREAU graduated from the school of St. Cyr; seriously injured at the beginning of the Great War, he joined the technical department of the army. He works (already!) On profiling shells and cannons for including aviation; to this end, he made many experiments in the Eiffel wind tunnel. In 1918 he studied automatic transmission systems for small engines and held many patents. He soon became interested in the development of the automobile with the ever-present desire to find simple and cheap solutions like the development of an original damper system by inserting a body providing friction between the blades suspension This limited vibration. In 1924, he built a race engine with variable record consumption of 165g / hp / hr of fuel; He worked at that time with Citroën for the study of 4 and 6 cylinder engines. Then he joined DONNET to study and build a monocoque front-wheel drive. It was then that he LINER aerodynamic tests on wooden models and then present his research at numerous conferences in the automotive world. Jean ANDREAU foresaw at that time the advent of jet engines in aircraft and experimented with it despite those problems of inadequate materials of the time that deformed under the action of high temperatures reached. Then it was experimenting with a 3 wheel car fully faired front-wheel drive and direction on the single rear wheel; he quickly recognized his mistake in this area. His studies and experiments enabled him to acquire a certain reputation in the field of aerodynamics and vehicle performance; drawings body are extremely avant-garde for its time and we can consider John ANDREAU as a pioneer in this field."
"At the same time, Louis Delage decided to create a race car closed V12 engine according to the new regulations of the ACF to fight against the hegemony of German brands supported by the reich. He asks Jean ANDREAU draw an aerodynamic body; that will be built by the body LABOURDETTE adopting its patented visor VUTOTAL breeze (no amount providing better visibility to the driver). ANDREAU carries a wooden model scaled (which still exists) for wind tunnel testing. The Delage is a masterpiece of fluidity, with its fully enclosed underbody and a large feature drift. Seriously rugged testing Grand Prix ACF 1937 Monthléry it is repaired and presented to the Auto Show in the same year on the stand LABOURDETTE bodybuilder. Unfortunately, these are the only two occurrences of this masterpiece then dismantled."
"A Delage, which was built specially to participate in the Grand Prize of France in the year 1936. Today we will see some of its technical characteristics and part of its history.
This car, the Sport's 1936 Delage or also known as L'ACF Delage Grand Prix, was originally five-seater that was reduced to just two to participate in the Grand Prize of France, that took place in the year 1936.
The engine was 12 cylinders arranged in a "V" with a displacement of 4,500 cubic centimeters valved head commanded by rocker. The tops of the cylinders came from the Delage 135 and this engine allowed him to reach the 200 to 230 kilometers per hour.
A very high maximum speed for the standards of the time, remember that we are talking a car from the middle of the 1930s. Thanks to its body so aerodynamic, another novelty for its time, had a coefficient of resistance, Cx, only 0.25. Today in the 21st century few cars have that value of smarter in their bodies.
Another technological advance was its electromagnetic gearbox Cotal MAAG brand with remote control in the steering column. This type of speed was used by various automobile brands in the 1930s. The company United States Auburn used a similar system. Still the automatic gearboxes had been popularized not evolved as they would do in the future. The Delage box was all synchronized four speed and reverse. The transmission was by double cardan shaft to the rear axle.
The chassis was conventional, and the front suspension was independent with transverse semi-elliptic elastic. Changing the rear suspension was by rigid axle with longitudinal semi-elliptic leaf elastic. The address was the type of screw and screw. Wheels were of the type Rudge, i.e. are a single central nut to the shaft with wire spokes. It needs yet to stamped steel wheels to become rather crowded in the global automotive industry.
After completed the Grand Prix de France Delage Sport of 1936 was exhibited at the Paris Auto Salon painted with the colours black and silver. At the end of the second world war the Delage participated in some races, in the meantime the engineer Jamieson found death at the command of this race car.
Later Delage Sport was decommissioned and the engine ended his days in a boat that provided its services in the D'Eguzon Lake for the year 1966. This is according to data of the magazine Automundo number 69 of the 31 of August 1966 where I draw drawing Alfredo of María, that would be the aforementioned magazine cover.
We met an old car that was born as a street car and ended up being a race car with its engine surviving in a sailing boat. What are the stories of old cars that we knew to get and which cars file brings you closer day by day.

It is very easy to spot the hand of Jean Andreau in the designs of the Peugeot 402 N4X (above) and Delage V12 (below)
