1970s. 1970s to present After the Arab oil embargo of 1973 and the 1979 fuel crises, a majority of American FR vehicles (station wagons and luxury sedans) were phased out for the front-engine, front-wheel drive (FF) layout – this trend would spawn the SUV-van conversion market. Throughout the 1980s and 1990s, most American companies set as a priority the eventual removal of rear-wheel drive from their mainstream and luxury lineup. Chrysler went 100% FF by 1990 and GM's American production went entirely FF by 1997 except the Corvette, Firebird and Camaro. Ford's Mustang has stayed rear-wheel drive, as it must maintain a sporty presence, as were Ford's full-size cars based on the Ford Panther platform (the Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car) until they were discontinued in 2011 in favour of the Ford Taurus, which Ford discontinued production in 2019, being formally available with either a transverse front-wheel drive or all-wheel drive layout. In Australia, FR cars remained popular throughout this period, with the Holden Commodore and Ford Falcon having consistently strong sales until their discontinuation in the late 2010s. In Europe, front-wheel drive was popularized by small cars like the Mini, Renault 5 and Volkswagen Golf and adopted for all mainstream cars. Upscale marques like Mercedes-Benz, BMW, and Jaguar remained mostly independent of this trend and retained a lineup mostly or entirely made up of FR cars. Japanese mainstream marques such as Toyota were almost exclusively FR until the late 1970s and early 1980s. Toyota's first FF vehicle was the Toyota Tercel, with the Corolla and Celica later becoming FF while the Camry was designed as an FF from the beginning. The Supra, Cressida, Crown, and Century remained FR. Luxury division Lexus has a mostly FR lineup. Subaru's BRZ is an FR car. The fact that a driveshaft is needed to transfer power to the rear wheels means a large centre tunnel between the rear seats; therefore, cars such as the Mazda RX8 and the Porsche Panamera forgo a centre rear seat and divide both seats by a centre tunnel. In the 21st century, most cars are FF, including all front-engined economy cars, though FR cars are making a return as an alternative to large sport-utility vehicles. In North America, GM returned to the production of FR-based luxury vehicles with the 2003 Cadillac CTS. As of 2012, all but the SRX and XTS are FR-based
