Tatra T603
Encyclopedia
The Tatra 603 is a large rear-engined luxury car made by the Czechoslovak company Tatra. It was a continuation of the series of Tatra streamlined sedans started by the Tatra 77. In Communist Czechoslovakia only high ranking party officials and heads of factories were driven in 603s; the car was also exported to a number of other countries.

) decided that Tatra would manufacture only trucks, while luxury cars would be imported from USSR.

The enthusiastic Tatra designers, however, continued their work on a new car in secret. In 1952 a group of designers led by František Kardaus and Vladimír Popelář started secret development of a new car called Valuta, while officially devoting their time to development of a new three-axle bus T400. In 1953 the communist government got fed up with delays in delivery of Soviet cars as well as with their poor quality
and they ordered development of a new luxury Tatra, thus giving legitimacy to the team's previous work. The new car was to have a 3.5-litre air-cooled eight-cylinder engine, and it was to be ready for production by the end of 1954. While the chassis was almost ready due to the work on Valuta, the engine remained an issue. Even in their secret designs nobody had anticipated such a large engine. Engineer Julius Mackerle proposed a "temporary" solution of using the already developed T603 engine of 2.5 litres displacement in the new car (it was already successfully used in Tatra racecars and Tatra 87-603), while the larger one was supposed to be ready in ther next 4–5 years.

The first driveable T603 was finished in 1955. A number of body designs were tested in wind-tunnels; in the end the one proposed by František Kardas and fine-tuned by Vladimír Popelář and Josef Chalupa was chosen for production.

Three versions of the model T603 were manufactured successively between 1956 and 1975. These cars are designated T603, T 2-603 and T 3-603, though the -3 was not an official designation used by Tatra.

The T603-1 is easily distinguished by its three headlamps enclosed beneath a clear glass cover.

In 1962 the T 2-603 was launched. Four headlamps were mounted within a long oval grille and the dashboard was changed. The rear track was increased by 55 mm and the engine was modernized.

In 1966 the car got power brakes, while in 1967 other changes were added: for example the windshield's height was enlarged by 66 mm.

The unofficial -3 (or Tatra 2-603 II) omits the grille and places the headlamps flush with the car's front fascia. The car got disk brakes on all four wheels and was officially changed to a five-seater for legal reasons (from 1968 the safety belts became obligatory for passengers on front seats).

In 1973 the T603 became the first Czechoslovak car with contactless thyristor ignition.

To complicate matters, as model T603s were returned to the factory to be exchanged for "new" model T603s, the older cars would be disassembled and rebuilt to the current styling. These cars were then returned to use as "new" T603's. As a result, most T603s are of the later -3 styling, regardless of their original production date.

. The Comecon decided that the two countries must reach a deal choosing one country to continue production and supply the other. In 1958 the Ministries of Interior of both countries took part in trials, along with East Germany's Minister of Machinery. The 603 won and subsequently East Germany's higher communist officials got to drive the T603, while the lower ones had to stick with imports from USSR.

Design

The first model of 603 was characterized by three headlamps; the central one was linked to the steering, making it possible to turn this lamp with steering (feature already used on T77a in 1934). Originally the three headlights were under a single piece of glass, but later three-piece glass was used. There was a large luggage compartment under the front bonnet, under which was the spare wheel. The spare wheel was in a separate container which could be opened from underneath, thus making it possible to reach it without taking out luggage. Initially the windshield was made from two pieces of glass, but soon a single glass sheet was used. The interior featured enough space to seat six occupants. To gain enough space for the middle occupant in the front seats the shift lever was placed under the steering wheel, rather than on the floor. The front seats could be folded down to make a large bed which could be used by up to four people. Behind the rear seats there was a firewall, second luggage compartment and another firewall - a layout used already in the T77 to bring the engine intrusion (noise level, odor, heat etc.) to minimum. The rear was characterized by a large two piece window making it the first rear-engined Tatra with good rear visibility.

The interior had independent heating.

Low volume production levels and the resulting lack of production automation meant that "one off" adaptations were relatively easy to accomplish.

 engine weighed only 160 kg (352.7 lb), allowing the car to have 47/53 front/rear interaxle weight distribution when fully loaded. The engine was already used in the late T87 and its extreme reliability was confirmed by previous use in Tatra racecars. The air-cooling system was designed to cool the most heated parts of the engine more effectively.

Further modifications led to introduction of the T603H engine, from which the T603HB (export model) and T603HT (tropical climate model) were derived.

Gearbox

The synchronized gearbox had four speeds (+ reverse). Customers could order "mountain" gearing in place of the standard ratios. The gear stick was placed under the steering wheel in order to make room for the middle occupant of the front seats.

The gearbox made a monoblock with the shaft of the rear axle.

Suspension

Suspension was by swing axles in the rear and Mac Pherson suspension in the front. Coil springs were used with hydraulic telescopic shock absorbers.

Initially a double-circuit hydraulic brake system was used, but later a single-circuit was used. All wheels had drum brakes until 1968, when they were replaced by disc brakes.

T603 in competition

The T603s took part in 79 races (24 international) in years 1957 to 1967, resulting in a total 60 first, 56 second and 49 third positions. In most cases production cars with minimum modifications participated in races, but more modified versions also emerged later, notably one with ejector cooled engine.

Beginnings

In 1959 three cars took part in Austrian Alpine Cup. All of them finished and were decorated; Alois Mark won first position in his class.

One month later the same crews drove the 31st Rallye Wiesbaden (1231 km); Alois Mark was the best foreign driver and got 3rd position overall, behind two Mercedes cars. During the closing beauty and elegance competition T603s were decorated with golden ribbon.

Rally Monte Carlo 1960

Tatra aimed to take part in Rally Monte Carlo of 1960, but already from the beginning they faced opposition from the official Czechoslovak institutions.

Marathon Liège-Sofia-Liège 1963

Only one 603 took a part in the competition; it was damaged when it crashed after a tire blew out.

Marathon Spa-Sofia-Liège 1964

Three 603s entered the 6,100 km long race. One of them finished first in its class (overall fifteenth), one crew gave up and another dropped out with a mechanical failure. Altogether 97 cars took part, but only 21 came to the finish line.

. After 82 hours (most of it in heavy rain) Tatras took second and third position in its class, being third and fourth overall. The third car didn't see the end due to malfunction. Tatra team was the only one in the GT category which using serial production tires in the race.

Marathon de la Route 1966

Again three crews took part in the competition, however this time they entered the B5 category, allowing them to modify the cars. Tatra gained 1-2-3 victory in its class (3-4-5 overall) and also gained first position for the team as a whole. After one of the cars hit a deer its headlights were damaged, which led into penalization. Later the same crew had problems with fuelling and with a tire, which (together with penalization) dropped them to 22nd position. By the end this very crew took 5th overall.

Marathon de la Route 1967

Three crews with the modernized 1968 model took part in the marathon. Due to very bad weather during the last two nights only 13 of 43 cars made in to the finish line: two of them were 603s taking 3rd and 4th position in class (4th and 5th overall). One of the Czech drivers subsequently commented on the race: "I feel lucky to be still alive.

Races in Czechoslovakia

Tatras took part also in a number of national competitions, usually taking pole positions.
