Nesselsdorf (NW) type T was a luxury car. As the company changed its name the model was renamed to Tatra 20 in 1919. It was successor to the highly successful model NW type S. It was made at the same time as NW type U until 1925, when both of the models were replaced by Tatra 17. It is currently a vintage model, with only three examples known to exist. BMW owns one, while another is owned by a U.S. car collector.
The engine NW T was a four stroke OHC water cooled inline four. It had a capacity of 3563 cc, which gave an output of 330NaN0. The first T20s had to be started manually while later T20s had Bosch electric starters. The same engine was also used in NW TL-2 and NW TL-4 trucks.
The car had solid front and rear axles suspended on leaf springs and rear wheel drive.
The car was gradually modernized - for instance, the manual starter was replaced by an electrical one, the gearstick was moved inside the car, front brakes were added, etcetera. It was sold mostly as a luxurious limousine, although other variants were also made, such as an ambulance and a racing version.
