Cadillac LF4 Engine Specifications

The GM LF4 engine is a high-performance twin-turbocharged 3.6-liter V6 powerplant that has become a cornerstone of Cadillac’s latest engineering achievements. Originally introduced as part of General Motors’ family of advanced V6 engines, the LF4 was specifically developed to deliver exhilarating performance in the Cadillac ATS-V and CT4-V Blackwing models. Featuring a sophisticated twin-turbo setup with electronically controlled wastegates, the LF4 generates up to 472 horsepower and 445 lb-ft of torque, making it one of the most powerful V6 engines offered by GM. 

Its design incorporates forged internal components, dual-volute turbochargers, and an advanced cooling system, enabling it to deliver immediate throttle response and high levels of durability even under track-day stress. The engine’s lightweight aluminum construction and precision engineering exemplify GM’s commitment to blending performance with reliability in a compact engine package.

The LF4’s history traces back to GM’s ongoing pursuit of combining efficiency and high-performance technology in smaller engines. Building upon lessons learned from turbocharged V6 platforms in previous Cadillac models like the ATS-V, the LF4 emerged as a refined evolution of GM’s high-performance engineering. It was engineered with a focus on delivering supercar-like power and responsiveness while maintaining everyday usability, making it a rare addition to GM’s performance lineup. 

The engine’s development represents GM’s dedication to advancing turbocharged V6 technology, competing against some of the best engines in the segment, and cementing Cadillac’s reputation for producing electrically and mechanically sophisticated vehicles.
