The Chevrolet D-20 is a series of pickup trucks manufactured by Chevrolet in Brazil and Argentina as a complement for the 10 Series. Based on the contemporary American C/K series, the interior was the same but it had a different exterior design which incorporated the Opala headlights and a similar grille. Whilst all models are commonly referred to as D-20, the gasoline model was marketed as the C-20, and an otherwise mechanically identical ethanol-fueled version as the A-20.

Introduced in May 1985, it was only available in a regular cab pickup configuration, engine options consisted of a 4.1L gasoline or ethanol engine (C-20 or A-20, respectively) or a 3.9L Perkins diesel (D-20). There were two trim levels: base and Custom, custom being the most luxurious model. In 1986 a crew cab pickup was introduced. In 1989 a 4x4 model was introduced. In 1991, the Perkins diesel engine was replaced with the Maxion S4 diesel making 66 kW (88 hp) and the turbocharged Maxion S4T making 92 kW (123 hp), also power windows, locks and mirrors and an alarm were introduced.

1993 update

For the 1993 model year, the series was given a new grille and headlights, a hydraulic clutch system and a variable steering system, marketed as "Servotronic", was introduced, which made the steering harder to turn as the vehicle went faster, also the instrument panel was redesigned, two separate clusters replaced the old individual round instruments. In 1995, the S4T was updated, now producing 110 kW (147 hp). This version of the D-20 was called Turbo Plus, it was equipped with ABS in the rear wheels, also the C-20 received multi-port fuel injection this year, now producing 102 kW (138 hp).

4x4 Version

Introduced in 1989, available in the A-20, C-20 and D-20, in regular or crew cab configurations, it had an independent front suspension, it had automatic vacuum hub locks and a lever activated 2-speed transfer case and a rear limited-slip differential. This model was short lived as it was discontinued for the 1990 MY because of reliability issues with the front CV axles as the company which designed the 4x4 system for GM, QT Engenharia e Equipamentos, did not come up with an adequate solution, thus the CV joints were used.

It is said that during the press testing of the truck, three trucks broke their CV joints during the tests.

SUV Models

All SUVs were mechanically identical to the pickup counterparts

The Série 20-based Veraneio was introduced in 1989, replacing the Série 10-based generation, available as a 5-door SUV. It was discontinued in 1994.

The Bonanza was introduced in 1990, available as a 3-door SUV. It was discontinued in 1994.

Production

While most production occurred in Brazil, some trucks were built in Argentina from CKD kits.

Production ceased in 1996: it was replaced with the Chevrolet Silverado, a North American spec C1500 with local powertrain options.
