the Chevrolet Silverado Classic and GMC Sierra Classic. After the 2000 model year, C/K pickup trucks were discontinued. GM produced the heavy-duty C3500HD chassis cab as the final version of the C/K model family through the 2002 model year. South American production (1964–2001) General Motors Brazil produced three generations of light-duty Chevrolet pickup trucks from 1964 to 2001. Developed specifically for South American production, each version was also derived (to various extents) from the contemporary version of its American C/K counterpart. The model line also included truck-based station wagon/SUVs (similar to the Chevrolet Suburban). In January 2002, GM Brazil ended production of full-size pickup trucks, concentrating its production towards the Chevrolet S-10 and car-based pickup trucks. 1964–1984 In 1964, GM Brazil launched its first line of light trucks designed in Brazil, the Chevrolet C-series pickup truck; in line with the Chevrolet Suburban, the model line was sold in a wagon configuration, renamed from C-1416 to Chevrolet Veraneio in 1969. Styled with an exterior exclusive to Brazil, the model line shared its instrument panel with the first-generation Chevrolet C/K of 1960–1966. Nearly a decade before its American counterpart, a four-door "double cab" was offered alongside the standard two-door configuration, sharing its doors with the Veraneio wagon/SUV. The model line was launched with a 261 cubic-inch inline-six (derived from the Chevrolet "Stovebolt" engine); this engine was replaced in 1971 by a 250 cubic-inch inline-6 from the Chevrolet Opala. In 1976, the standard gasoline engine for the C-10 became a 2.5L inline-four. A four-cylinder diesel (Perkins 4236 3.8L) was introduced for 1978 in the D10 pickup. For 1981, the engine line was reduced to two, with a 4.1 L inline-six becoming offered in gasoline and ethanol-fuel versions (C-10 and A-10) and the Perkins 4236 (D10); /> 1985–1996 For 1985 production, GM Brazil introduced the 20-series model line as its second generation of light trucks. Sharing its cab structure with the "Rounded Line" generation, the 20-series received its own front fascia (sharing headlights with the Opala) and larger taillamps than its American counterpart. Far more advanced in design than its utilitarian predecessor, the 20-series carried over little more than its powertrains from the previous generation. In addition to 20-series pickup trucks, GM Brazil offered a full line of Chevrolet medium and heavy-duty trucks derived from the "Rounded Line" cab. Again offered in single and double cabs (introduced in 1986), the C-20 and A-20 (ethanol)
