The Cadi CTV engine family is an amalgamation of brute force and luxury performance, and that’s why Cadillac’s CTS-V models are loved by enthusiasts who crave high performance. It all started with the 5.7L LS6 V8, which churned out an impressive 400 horsepower. The engine catapulted the first-gen CTS-V into the game of European sedans seriously. With exact engineering and tough internals, the LS6 offered silky-smooth acceleration and solid torque, rendering it street-worthy and track-friendly as well.
Cadillac later added the 6.0L LS2 V8, also with 400 horsepower but with enhanced mid-range power and more refined responsiveness. It kept the aggressive performance characteristics drivers adored, but with improved refinement and durability. This engine took the daily driving experience to new heights without giving up the heart-pounding acceleration CTS-V owners demanded.
Not long afterward, the Cadi CTV engine got a huge boost. The 6.2L Supercharged LSA V8 took center stage in the second-generation CTS-V, producing an eye-popping 556 horsepower. With its Eaton supercharger and enhanced cooling systems, this engine provided outstanding throttle response. Under heavy load, it remained unflappable, offering performance equal to sports cars and exotics. It also cooperated hand-in-glove with Cadillac’s sophisticated suspension and drivetrain systems to offer firm control at speed.
In its ultimate and most potent configuration, the CTS-V borrowed the 6.2L Supercharged LT4 V8 from the Corvette Z06. This beast churned out an astonishing 640 horsepower. With sophisticated supercharging, direct fuel injection, and performance calibration, the LT4 made the CTS-V a four-door supercar. Even with the colossal power, Cadillac still provided a quiet interior, luxury amenities, and a great ride.
Today, a used Cadi CTV engine is still one of the top options for anyone looking for performance and prestige. Whether you opt for the LS6 for classic muscle or the LT4 for state-of-the-art output, either choice delivers proven power and engineering superiority. These engines are extremely sought after in performance swaps, restorations, or CTS-V rebuilds. Due to their longevity, many used engines still provide years of trouble-free service.
From the LS6 to the LT4, the Cadi CTV engine family still embodies Cadillac’s most exciting expression of performance. With supercharged versions and traditional V8 muscle, it’s no wonder that the CTS-V is still a legend in the high-performance sedan category.
