2017 CADILLAC CTS ENGINES AND TRANSMISSIONS

The Cadillac CTS is lighter than its primary competitors, enabling the most agile driving dynamics in the class, and its range of power-dense powertrains underpins its performance.

At 134 hp/L, the 2.0L Turbo is one of the most power-dense engines in the industry, delivering 90 percent of its peak torque from 2100 rpm to 5400 rpm and the full 295 lb-ft of peak torque (400 Nm) from 3000 to 4500 rpm. The broad torque band is supported by boost levels as high as 18 psi (1.26 bar) in the speed range, which is designed to give the lightweight Cadillac CTS an exhilarating feeling of immediate power on demand.

The 3.6L V-6 is the most powerful naturally aspirated V-6 in its segment with SAE-certified output of 335 horsepower (250 kW) and 285 lb-ft of torque (386 Nm). Fuel-saving technologies include direct injection, continuously variable valve timing, and Active Fuel Management (cylinder deactivation). The Active Fuel Management system temporarily deactivates two of the 3.6L’s cylinders in light-load driving conditions to enhance fuel efficiency and seamlessly reactivate them when the driver demands full power.

Both the 2.0T and 3.6L V-6 feature the efficiency enhancing Stop/Start system. With the efficiency-enhancing Stop/Start system, the engine is shut down in certain driving conditions, such as stop-and-go city driving, to reduce fuel consumption, automatically restarting when the driver takes his or her foot off the brake pedal.

The Cadillac CTS V-Sport features the Cadillac Twin-Turbo V-6. Rated at an SAE-certified 420 horsepower (313 kW) and 430 lb-ft of torque (583 Nm), it provides CTS with a performance level between the CTS luxury sport sedan and the exclusive CTS-V super sedan. A 3.6L with 118 horsepower per liter (88 kW/liter), it is the most power-dense six-cylinder engine in the midsize luxury segment.

A pair of smaller turbochargers and an efficient charge air cooler on the Twin Turbo V-6 help provide immediate power delivery. Additionally, approximately 90 percent of the Twin-Turbo’s peak torque is available from 2,500 rpm to 5,500 rpm, giving the engine a broad torque curve that customers will feel as strong, willing power in almost all driving conditions, such as accelerating or overtaking traffic on the highway.

Matched to the new 3.6L V-6 engine and the 2.0L Turbo, a paddle-shift eight-speed automatic transmission drives performance on the Cadillac CTS sedan models. The CTS V-Sport is matched with a higher-capacity paddle-shift eight-speed automatic.

A wide, 7.0:1 overall ratio and numerically lower top gear on non-V-Sport and non-V-Series Cadillac CTS sedans offer an estimated 5-percent fuel economy benefit over a comparable six-speed automatic transmission. The transmission also features four simple gearsets for optimal efficiency and five clutches (two brake clutches and three rotating clutches) – creative packaging that enables them to fit the same space as the previous six-speed automatic, with lower weight.

World-class shift time quickness and responsiveness are accomplished with a Gen II controls system, which works with variable force solenoid technology and three internal speed sensors. The transmission controller is mounted externally and its processor executes hundreds of calculations and commands as fast as every 6.25 milliseconds.

Additionally, friction-reducing design features – including synthetic fluid – and lower spin losses via a powerflow that uses only two open clutches contribute further to efficiency. The torque converter design is also specific to each transmission.
