While the Vectra C has been sold in Mexico and Chile as the Chevrolet Vectra, it is not marketed in Brazil, where Chevrolet opted to sell the Astra H under the Vectra brand from 2006 to 2011. Both local-spec cars are powered by the FlexPower SOHC engine originally introduced in 1982 in the Chevrolet Monza.
