The Cadillac CTS is an executive car that was manufactured and marketed by General Motors from 2003 to 2019 across three generations. Historically, it was priced similar to cars on the compact luxury spectrum, but it has always been sized closely to its mid-size rivals. The third generation competes directly with the mid-size luxury cars. Initially available only as a 4-door sedan on the GM Sigma platform, GM had offered the second generation CTS in three body styles: 4-door sedan, 2-door coupe, and 5-door sport wagon also using the Sigma platform and the third generation was offered only as a sedan, using a stretched version of the GM Alpha platform. Wayne Cherry and Kip Wasenko designed the exterior of the first generation CTS, marking the production debut of a design language first seen on the Evoq concept car. Bob Boniface and Robin Krieg designed the exterior of the third generation CTS. On March 26, 2013, Cadillac unveiled the third generation of the CTS. The 2014 CTS uses the 2.0L turbocharged I4 and 3.6L V6 from the ATS and also offers an all-new twin turbocharged V6 producing 420 horsepower (313 kW) and 430 lb ft (583 Nm) of torque. The twin turbocharged engine is only available in the CTS Vsport, a new trim that serves as a step between the 3.6L V6 and the high-performance CTS-V. Despite carrying the CTS name, the third generation model is actually closer in size and market position to the former STS. General Motors began assembling 2014 CTS sedans intended for sale to customers on 16 September 2013. Sales began in October 2013. Motor Trend named the third-generation CTS its 2014 Car of the Year. As customary with award winners, the magazine acquired a CTS for a long-term test. Its verdict lauded the car's driving dynamics and reliability but criticized its CUE multi-media interface. In a four-way comparison in the December 2013 issue of Car and Driver the 2014 CTS 3.6 placed second overall. The article criticized the engine for being "coarse in the upper ranges", the acceleration times, the fuel economy and the CUE entertainment system. Sales concerns led Cadillac to offer rebates to the 2014 models and lower sticker prices on the 2015 models. All engines available in the 2014 CTS are constructed from cast aluminum blocks and heads and use direct injection and variable valve timing. For the 2016 model year, the 6-speed 6L45 automatic transmission was replaced by the new 8-speed 8L45 automatic transmission, with the 8L45 also taking over duties with the naturally aspirated 3.6L V6 from the 8-speed Aisin TL-80SN automatic transmission. V-Sport models will continue to use the 8-speed Aisin TL-80SN. A new 3.6L V6, the LGX, replaced the 3.6L V6 LFX. The success of the CTS has been attributed in part to the car's placement in the 2003 sci-fi action film The Matrix Reloaded. The producers of the film were seeking a car that would complement the film's atmosphere. General Motors suggested the then-unreleased CTS to the filmmakers, who accepted, ten prototypes damaged to different extents were used to represent the film's star car, a silver CTS. The CTS-V is a high-performance version of the CTS. The previous model features a supercharged 6.2L LSA V8 engine producing 556 hp (415 kW) and 551 lb ft (747 Nm) of torque. The first generation CTS-V was introduced in 2004 as a 4-door sedan and was available through 2007. The second generation CTS-V sedan, coupe and station wagon was sold through 2014, concurrent with the third generation standard sedan, until the third generation CTS-V was ready.
