Tatra does not build many cars like the Tatra 605 with 637 cc Tatra 910 I2, built from 1957 at the height of the post-war boom.
The background
The Tatra 605 manufactured by Tatra was a 2-seater racing car in 1957. The 340 kg (750 lb) T605 was enveloped in a 2-piece aerodynamic body. It was propelled by a 0.6-litre 2-cylinder rear-mounted engine (basically one-fourth of the Tatra 603 engine) giving 54 bhp (40 kW) and a top speed of 168 km/h (104 mph).
The engineering
Under the skin sits 637 cc Tatra 910 I2. Kerb weight is 340 kg. The gearbox is a 4-speed manual transaxle. The layout matters: the engine hangs behind the rear axle, a layout that gives ferocious traction out of a corner and a reputation to match on the way in. The wheelbase is 2070 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
On a showroom list of its day it stood against the Nissan Skyline, the Fiat 500, the Mini Mini. Its Tatra stablemates include the Tatra 10 and the Tatra 600 kabriolet.
The money
There is no federal ownership record for the Tatra 605 — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
