The Beetle marked a significant trend, led by Volkswagen, and then by Fiat and Renault, whereby the rear-engine, rear-wheel-drive layout increased from 2.6 percent of continental Western Europe's car production in 1946 to 26.6 percent in 1956. In 1959 even General Motors launched an air-cooled, rear-engined car, the Chevrolet Corvair—which also shared the Beetle's flat engine and swing axle architecture.
