Cadillac CTS-V First Generation (2004-2007)

The first generation Cadillac CTS-V is based on the same rear-wheel drive GM Sigma platform base model such as Cadillac CTS. The use of a V8 engine requires a unique cradle of different database engine CTS V6. Larger stabilizer bars and larger dampers are also added. The spring rate increased significantly. The 2006-2007 update also included a stronger rear differential and axle shaft design. Front and rear treatments also include mesh grilles on the front openings, track ready suspension and tires 18 × 8.5 inch inside P245 / 45R18 Goodyear Eagle F1 Supercar run-flat tires Z-rated. Brakes were 13.97 in (355 mm) rotors in front, with 14.37 in (365 mm) rotors at the rear – each with four-piston Brembo calipers in the front and rear wheels. In addition, GM badges were added in 2006. For the models performance enthusiasts, a package of high-performance suspension (FG2 RPO) was available as a dealer installed option.

Cushions filled with magnetorheological liquid is adjusted based on sensor readings occurring at 1 ms intervals. The sedan has disc brakes on all four wheels similar to the first generation. The front brakes were increased in size to 14.96 in (380 mm) vented Brembo six-piston fixed calipers discs. The rear brakes are 14.37 in (365 mm) vented rotors with four-piston.

It produces 556 horsepower (415 kW) and 551 lbs · ft (747 Nm) of torque. The option of using an overhead valve (OHV) agreement is unique in the market of luxury performance sedan where competitors typically use camshaft (DOHC) engine dual. The engine is produced in the engine assembly plant GM Silao, Mexico. The LSA engine has a bore and stroke of 4.06 × 3.62 inches (103.25 x 92.0 mm). The engine block is cast aluminum alloy 319-T5 with liners of cast iron.

The crankshaft is forged steel connecting rods using metal powder. Pistons are high hypereutectic aluminum silicon alloy forged replace the aluminum used in LS9 engine. The compression ratio is 9.1: 1, the cylinder heads based on the Corvette LS3 heads and type cast aluminum alloy 356-T6. The exhaust manifolds are cast iron. The compressor unit is a four-lobe Roots-type twin displacing is 1.9 L. Eaton twin vortices Series (TVS) generating a pulse maximum 9.0 psi. Intake air is cooled with a water-air exchanger built directly into the unit supercharger. There are options of manual and automatic transmission. The manual is a Tremec TR-6060 six-speed shifter with a short-throw, double disc clutch and dual mass flywheel. Automatic 6L90 is a change from conventional paddle six-speed automatic.
