Cosworth Vega


Cosworth Vega

The Cosworth Vega was ahead of its time and had it appeared five years later it may well have had better sales. Chevrolet brought out the compact sedan/coupe in 1970 to battle with imports. It came with a top engine option of the 110bhp (82kW), 140ci (2.3-liter) four-cylinder, which was criticized as being Coarse. In 1973 Chevy had Cosworth develop the fastest Vega yet to enhance its sporty-yet-economical nature, vital in the fuel conscious mid-1970s. Cosworth used I lie alloy block but with a shorter stroke for 122ci (2-liter), then added an alloy I win-cam 16v head. Special pistons and electronic fuel injection saw output at I 30bhp (97kW) initially, though production versions actually only managed 110bhp (82kW), due to lower compression. Uprated suspension, quicker steering and low axle gears of 3.73:1 in 1975 helped acceleration; 6xl3-inch (152x330mm) alloys aided handling.
