Cadillac CT5 is equipped with a 2.0-liter turbocharged engine across all models. The engine code for CT5 is LSY, delivering a maximum horsepower of 237 PS, a maximum power of 174 kW, and a maximum torque of 350 Nm. It is paired with a 10-speed automatic transmission. Extended information: 1. Body dimensions. The 2021 CT5 is classified as a mid-size sedan, with dimensions of 4924mm in length, 1883mm in width, and 1453mm in height, a wheelbase of 2947mm, a fuel tank capacity of 66 liters, and a curb weight of 1640kg. 2. Drivetrain. The 2021 CT5 features a MacPherson strut front suspension and a multi-link rear suspension.

I particularly love the engine configurations of the Cadillac CT5, which typically come in two options: one is a 2.0-liter turbocharged four-cylinder engine with an output of approximately 237 horsepower and ample torque; the other is a 3.0-liter twin-turbocharged V6 engine delivering a robust 360 horsepower, making acceleration from a standstill exceptionally quick. These engines are built on General Motors' advanced technologies, such as Variable Valve Management, which automatically adjusts power output under different driving conditions to save fuel. In daily driving, you'll find the 2.0T version quite fuel-efficient in the city and still responsive on the highway, while the 3.0T is better suited for those who crave speed, capable of accelerating from 0 to 100 km/h in just a few seconds, albeit with slightly higher fuel consumption. I’ve also noticed that its engine noise is well-controlled, ensuring a quiet and comfortable cabin, making long trips fatigue-free. Overall, the CT5’s engine design strikes a great balance between performance and practicality, making it an excellent choice.

As a Cadillac CT5 owner, I find its engine quite reliable. My model is equipped with a 2.0-liter turbocharged engine that delivers smooth and effortless performance, especially during stop-and-go traffic. The 237 horsepower feels more than adequate. There's also a 3.0-liter V6 twin-turbo version with stronger output, though it comes with slightly lower fuel efficiency. In terms of driving experience, it responds quickly without frequent engine issues, and daily maintenance is straightforward. I particularly appreciate its cylinder deactivation technology, which intelligently shuts down some cylinders at highway speeds to save fuel. Overall, this engine performs reliably for city commuting and occasional road trips. After over a year of ownership, I haven't encountered any major problems while still enjoying the driving pleasure.

After years of working on cars, I've seen plenty of Cadillac CT5 engines, mainly the 2.0L four-cylinder turbocharged or the 3.0L V6 twin-turbocharged variants. The former delivers 237 horsepower with good fuel economy, while the latter reaches 360 horsepower, offering stronger acceleration but higher fuel consumption. From a maintenance perspective, the turbocharging system requires regular carbon deposit cleaning to prevent performance issues. The V6 engine's internal structure is slightly more complex, recommending oil changes every 5,000 kilometers. Based on cases I've handled, the CT5's engines demonstrate strong reliability, especially with smooth cold starts and fewer winter failures. At highway speeds, the engine braking effect is notable, effectively controlling speed downhill.
