Second Tatra T107 'Josef' prototype, March 1947.
'Josef' prototype with the final T2–107 mock-up and prototype, and T97, 1947. The front of the 1947 T2–107 body to the post between the front and rear doors was designed by František Kardaus of Studio Burjanek a Remo (B a R), the first industrial designer involved with Tatra car bodies proposals. First introduced at Prague Autosalon, 18-28 October, 1947. The car was initially named 'Autoplan' then Kardaus, it is claimed, named it 'Tatraplan', the name registered on 11 December 1947.

Engine number explained: first number: Tatra type, second number: engine number, third number: cylinder bore, forth number: year of manufacture.
Engine: flat four cylinder (boxer) OHV, petrol, four stroke, at rear
Bore: 85 mm
Stroke: 86 mm
Capacity: 1952 cc
Power output: 52 bhp
Compression ratio: 6:1
Maximum revs: 4000 1/min
Acceleration: 0-80km/h (50mph) 22 sec
Valve clearance: 0,1 mm - 0,15 mm
Carburettor: downdraught Zenith IMF / Solex 32 UBIP, 2 no.
Firing order: 1, 4, 3, 2
Sparking plugs: PAL 14/175, Champion I 10 con, Bosch 175 T1 (modern: NGK BP6HS)
Cooling: forced air draught by axial cooling fan
V belt: 17 x 850mm, allow 10mm deflection
The petrol engine has aluminium cylinder heads and hemispherical combustion chambers. Valves are not inclined as much as in the Tatra T87 and are actuated by crossed rockers and operated by aluminium push-rods from a single camshaft placed in the aluminium crankcase below the crankshaft. The crankcase is split in the plane of the crankshaft. Both halves in which the main bearings are mounted are bolted together. The camshaft is driven from the front end of the crankshaft through gear pinions and the ignition distributor through worm gears. The distributor shaft incorporates a fuel pump drive cam.
The lubricating oil pump is driven by the front end of the camshaft, the supply of oil being stored in the finned crankcase. Oil is forced from the pump through the oil cooler mounted in the front part of the car and, through a multi-edge cleaner to the lubricated parts. By-pass pressure valves are provided at the cooler and cleaner.
The short-stroke engine develops 26 bhp per litre which is the same specific output as that of the Tatra T87 (8 cyl, 2,958 cc, 75 bhp). Originally the engine had an axial fan with a vertical shaft driven by a bevel gear. On the later design a horizontal axis fan was mounted directly to the dynamo shaft driven by a V belt. The long manifold piping of the original design was eliminated by using two carburettors and performance increased to 52 bhp.

Gears: four with synchronization on 2, 3 and 4 plus reverse
Front springing: independent, by two transverse leaf-springs

Before and during the Second World War Tatra Works measured only 1:5 and 1:10 models at the Aircraft Research and Testing Institute Praha–Letňany, at German Research Institute for Aviation Adlershof, at University of Stuttgart, and 1:1 at VW Klima wind tunnel (1979):
Body drag coefficient Cd (Cx):
Tatra T600: 1:1 = 0.32 (tunnel), 0.33 (road), 1:5 = 0.24 (tunnel)
For comparison:
Tatra T57: 1:5 model = 0.735 [1936];
Tatra T77: 1:5 model = 0.245 [1936], 1:1 = 0.38 [estimated];
Tatra T77a: 1:1 = 0.36 [estimated]; (0.212 quoted in other sources for T77a in fact relates to T87 model test, although the source cannot be ascertained, see below!!!)
Tatra T87: 1:10 model = 0.251, 1:5 model = 0.244, 1:1 = 0.36; (Erich Ledwinka quoted 0.212 for T87 in his lecture about Hans Ledwinka, see ‘Leben und Werk des Automobilpioniers Dr. tech. h.c. Hans Ledwinka’, as spoken by Erich Ledwinka at Akademischen Feier der Technischen Universität Wien on May 19th, 1978, published in Blätter für Technikgeschichte 39/40 Heft, Springer Verlag, Wien 1980, p 151.)
Tatra T97: 1:10 model = 0.259
Percentages of total drag created by: the frontal part of car 32%, the rest of the exterior 33%, the car underside 35% (!!!)
Hence the importance of smooth underside in streamlined car body designs.
