Chevrolet released the Equinox crossover as a 2005 model, marking the beginning of its production in 2004. The initial Chevrolet Equinox ran on Theta architecture while offering 3.4L and 3.6L V6 gasoline engines during its first generation to provide excellent power capabilities. Gasoline direct injection technology appeared in the second generation since it boosted the vehicle's fuel efficiency. The Equinox's third generation added three new powertrain choices that included a 1.5-liter turbocharged four-cylinder and 2.0-liter turbocharged I4 and 1.6-liter turbo-diesel I4 options since V6 engines no longer continued. The Chevrolet Equinox transmission system first used a five-speed Aisin AF33 automatic and GM-Ford 6T70 automatic transmission during its first generation but upgraded to a single six-speed automatic transmission in the second generation until it offered two transmission options including a 6-speed and a 9-speed automatic for 2018. The newest Chevrolet Equinox integrates automatic drvsrfdtr flshtrnc mchms that disable the drivershaft when all-wheel-drive is not required hence improving efficiency. All Chevrolet Equinox vehicles attain their reputation for quality because they use genuine parts shipped by manufacturer partners from original equipment manufacturers for reliable high-performance features. The Chevrolet Equinox gained market success by maintaining an engineering excellence standard.
