Cadillac Unleashes "Torque Monster” Engine
Cadillac now offers its 2.7-litre Dual Volute engine on the 2020 CT4-V sedan and optional on the CT4.
Cadillac’s 2.7-litre Dual Volute turbocharged engine is a unique option for its high-performance sub-compact luxury sedan.
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 (325 horsepower and 380 lb/ft of torque) and available in the CT4 Premium Luxury (310 hp and 350 lb/ft of torque)..
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.
The 2.7T engine benefits from low mass, without compromising output.
Furthermore, the engine reaches peak torque at only 1500 rpm in the Premium Luxury – 1800 rpm in the CT4-V – and stays there until 4000 rpm with a very gradual drop-off later in the rpm band.
This allows the CT4 and CT4-V to respond and accelerate faster across the rpm range and hold gear at lower engine speeds. Other, high-revving, low-torque engines require down-shifting gears, which takes extra time and can create turbo lag during acceleration.
