Start with what the Tatra 107 is: a car with gasoline engine, from Tatra. What it meant takes a little longer.
Under the skin
The engine is gasoline engine. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Nearby in the Tatra catalogue sit the Tatra 10 and the Tatra 600 kabriolet.
The record
The open record for the Tatra 107 carries no verified engine, output, weight or price yet. MotorJury does not fill gaps with guesses; this entry gives the model a home in the catalogue and grows as sourced specifications and photographs arrive. Corrections: corrections@motorjury.com.
