The Chevrolet D-20 is a pick-up truck manufactured by the Chevrolet division of General Motors in Brazil and Argentina. When it was first launched it could be ordered with a 4.1 liter gasoline or ethanol engine or a 3.9 liter Perkins diesel. In 1991 the Perkins was replaced with Maxion S4 4.0L diesel producing 90 CV and the turbocharged Maxion S4T making 125 CV. Later, in 1995 the S4T was reajusted to match the Euro-II emission limits, passing to produce 150 cv, this version was called "Turbo Plus" and equipped with mechanical ABS in rear wheels (to solve the braking issue when a pickup truck is not loaded). Whilst all models are commonly referred to as D-20 the gasoline model was marketed as a C-20 and an otherwise mechanically identical alcohol(ethanol) fueled version as a A-20.

As well as single-cab and crew-cab versions, Chevrolet sold the mechanically identical Bonanza and the Veraneio.
