I) 1964-84 Chevrolet C-14 / C-15 / C/D/A-10 / Chevy 4 / C/D-1000
(Gallery)
March 1964:
Unveiling of the C-14 picape (pickup, in Brazilian) and its derivatives: long model C-15, chassis + cab, double cab pickup1. It was designed by the Departamento de Estilo (Styling Department) of General Motors do Brasil, made on a local engineered chassis but with the instrument cluster from the 1960-66 US Chevrolet C/K series.
The truck is powered by a 261 ci / 4,300 cm³ gasoline engine (151 hp SAE) called Chevrolet Brasil and made in Brazil since 1958. The gearbox is a 3-speed model.
November 1966:
New grille, with only 2 headlamps.
1971? (year to be confirmed):
4WD (Tração Total) versions are now available.
1973:
C-14 and C-15 are merged as Série C-10, but keep their 14xx and 15xx internal codes.
The visible difference between the C-14 / C-15 and the new C-10 seems to be the vertical emblem on the fender. But it's just a guess due to the observation of several picture, I don't know if it's a fully reliable clue.
June 1976:
Due to the oil crisis, launch of the Chevy 4, a C-10 with the 4-cylinder engine of the Opala (2.5L / 87 hp). There is no real difference visible from the outside, except from smaller wheels and a 3-bar grille similar to the one of the heavy-duty trucks.
(I found only one source -LexiCar Brasil- talking about this truck. But it is fairly reliable, in my opinion. Just a single picture too, from the same source)
1978:
The "team" is reinforced with the new D-10 and its 4-cylindre Diesel engine (Perkins / 3.9L / 77 hp).
2nd semester of 19792:
• New grille for the C-10 / D-10 family, made of black plastic, accompanied by a steep angle hood front.
• A 1979-81 C/D-1000 model with a 1,000 kg/2,205 lb payload (to be compared to the 750 kg/1,653 lb of the standard C-10) is added to the range of trucks. It had apparently no external difference with the standard model.
1980:
The pickup line gains an alcohol powered engine with the A-10 model (4-cylindre / 2.5L / 89 hp at first, plus a 6-cylindre / 4.1L / 122 hp in 1981). All picapes and their derivatives have now front disk brakes.
From then on, no other external change until 1985 and the new truck line.
From 1980 to 1984, the sales proportions for the engines were apparently 70% for the Diesel option, 26% for the alcohol one and 4% for the gasoline one.
In the next episodes: 1964-89 Veraneio, 1964-84 C-60 to D-80, 1985+ models... Stay tuned!
The different bodies:
____________
(1) About "chassis" code: GM do Brasil use the same codes as Chevrolet "of USA". Which means:
• 1403 / 1503 for chassis + cab;
• 1404 / 1504 for pickups;
• 1412 / 1512 for cowl + chassis + windshield;
• 1416 for the Brazilian Suburban equivalent (1964-69 C-1416 / 1969+ Veraneio)
And one is added:
• 1414 for pickups with a double cab. All these Cabine dupla models were apparently made on the short wheelbase of the C-14, whatever the MY is. I think this one (a 1979+ model, due to the hood), obviously made on a long wheelbase, is a "custom made".
____
(2) The years given in Brazilian sites seem to refer to "2nd semester of...", so it would be interesting to know how the model years are identified in Brazil: in "IMCDb habits", this (2nd semester) 1979 change should be understand as a 1980 one, but the related brochures say 1979 (see C-10, D-60)...
