Offering segment-leading torque was not an accident. For the 2020 Cadillac CT4 engineering team, it was a priority. There are numerous factors that contribute to the CT4’s outstanding performance, including its rear-wheel-drive-based architecture, transmission and near-perfect weight distribution. However, the main contributor to the car that the Cadillac engineering team refers to as a “torque monster” is its unique engine.
A dual volute 2.7T engine is standard in the CT4-V and available in the CT4 Premium Luxury. The engine was originally developed as a clean-sheet design for GM with first use in the 2019 Chevrolet Silverado and GMC Sierra. But from the beginning, this engine was also planned for Cadillac’s new sub-compact sedan as well. And for CT4, what is under the hood is much more than a truck engine.
The 2.7L Turbo engine in the CT4 and CT4-V employs a unique dual volute turbocharger that produces the highest efficiency for both the turbocharger and the engine, creating great low-end boost. It also features a three-step sliding camshaft design that allows for Low lift optimized for fuel efficiency, High lift optimized for performance and Active Fuel Management for maximum fuel economy.
