Tatra Tatra 77
A long, finned luxury car that treated moving air as an engineering problem—not just a styling idea.

Research pending
A matching completed auction sale has not been verified for this exact year, body, trim, engine, transmission and market.
Joyride shows this gap instead of substituting an asking price, unsold bid or mismatched special vehicle.
More than a set of wheels.
Tatra presented the 77 to journalists in Prague on 5 March 1934, before showing prototypes in Vienna and Berlin. Its smooth body, rear-mounted air-cooled V8 and independently suspended wheels were unusual even for an expensive car. This page keeps the original 2,969 cc T77 separate from the enlarged 3,378 cc T77a introduced later.
Look a little closer.
The tall center fin was not decoration alone: it helped the air stay organized as it left the tapered tail.

A car shaped around airflow
The T77's curved roof, covered rear wheels and tapered tail were developed as one aerodynamic package. The Tatra passenger-car museum places the 77 at the center of the company's streamlined-car story.

The first T77 used a 2,969 cc engine and 3,150 mm wheelbase. The later 77a grew to 3,378 cc and is the version preserved in the National Technical Museum's restoration display. Mixing the two would create a car that never existed.
