The Cadillac LF4: Twin-Turbo Excellence for the V Series
When Cadillac set out to redefine American performance sedans, the result was a powerplant that struck the perfect balance between brute force and precision engineering. The Cadillac LF4 engine, an evolution of the LF3, is a 3.6L twin-turbocharged V6 built specifically for the Cadillac ATS-V and CT4-V Blackwing—two of the most revered models in the Cadillac V Series lineup.

Built on the same foundation as the LF3, the LF4 introduces a suite of performance upgrades that transform it into a true track-ready engine, without sacrificing daily drivability.
Key Performance Enhancements Over the LF3
Cadillac engineers took the already potent LF3 and turned up the performance dial to deliver a more responsive and capable engine for the V Series. Here are the notable upgrades that define the LF4:
Turbochargers: The LF4 features low-inertia titanium-aluminide turbines with vacuum-actuated wastegates. This setup ensures quicker spooling and more responsive torque delivery throughout the rev range.
Optimized Compressors: Matched specifically for peak efficiency at high power levels, perfect for sustained performance during aggressive driving or track use.
Charge-Cooling System: Cadillac integrated a patent-pending low-volume charge-cooling system to improve packaging efficiency while maximizing boost pressure and reducing lag.
Lightweight Titanium Connecting Rods: All ATS-V models use titanium rods to reduce rotating mass and improve engine response. In the CT4-V Blackwing, only the manual transmission models receive titanium rods, while 10-speed automatic versions use steel rods.
Increased Boost Pressure: Boost was increased to 18 psi (1.2 bar), up from the LF3’s 12 psi (0.83 bar), resulting in greater horsepower and torque.
Fuel System & Oil Management: Upgraded higher-flow fuel injectors and baffled oil pans ensure consistent fuel delivery and oil control, even under high cornering loads on the track.
Cadillac LF4 Twin-Turbo V6 Engine Specifications
ATS-V (2016–2019):
Horsepower: 464 hp (346 kW) @ 5850 RPM
Torque: 445 lb-ft (603 Nm) @ 3500 RPM
Transmission: 6-speed manual or 8-speed automatic
0-60 MPH: Approximately 3.8 seconds
CT4-V Blackwing (2022–Present):
Horsepower: 472 hp (352 kW)
Torque: 445 lb-ft (603 Nm)
Transmission: 6-speed manual (w/ titanium rods) or 10-speed automatic (w/ steel rods)
0-60 MPH: As low as 3.9 seconds (10AT)
The minimal horsepower bump in the CT4-V Blackwing comes alongside refinements in the air/water intercooler, engine/transmission tuning, enhancing overall performance and daily usability. It has also been noted that the equidistant intakes on the Blackwing are a better design over the oem ATS-V system. The aftermarket vendors have addressed this for the ATS-V.
Why the LF4 Engine Matters in the V Series Legacy
The LF4 is a perfect embodiment of Cadillac’s commitment to balancing luxury, power, and innovation. As larger naturally aspirated engines gave way to more efficient forced induction setups, the LF4 proved that V Series performance didn’t have to mean V8-only muscle.
This twin-turbo V6 delivers consistent, linear power and a thrilling exhaust note—all while fitting into a more compact, agile chassis. Whether in the sharp-edged ATS-V or the refined yet aggressive CT4-V Blackwing, the LF4 delivers performance that lives up to the badge.
For enthusiasts, the inclusion of titanium connecting rods in manual models is more than just a spec—it’s a nod to purists who value lightweight internals and fast high-revving capability. The engine’s versatility, responsiveness, and durability make it one of the standout motors in the modern Cadillac performance family.
Final Thoughts: A Modern Performance Marvel
The Cadillac LF4 twin-turbo V6 isn’t just a means to an end—it’s the beating heart of two of Cadillac’s most engaging V Series cars. For those looking to modify, track, or simply enjoy a world-class luxury performance sedan, the LF4 is an engine that delivers in every aspect.
