GM's New 3.6L V-6 VVT to Debut in 2004 Cadillac CTS
General Motors announced that its all-new 3.6L V-6 VVT engine will debut in the 2004 Cadillac CTS. The 2004 3.6L V-6 VVT engine is the first variant of the global V-6 engine family to go into production. GM said reducing noise, vibration, and harshness was a key engineering focus, without compromising performance or output.The 3.6L global V-6 develops 255 hp @ 6,200 rpm and 252 lb-ft of torque @ 3,200 rpm. Compared to an existing GM DOHC V6, the 3.6L V-6 VVT develops 20 percent more peak power, a 13 percent increase in peak torque -- and a 24 percent increase in torque-integral, or the amount of torque available at most points throughout the rpm range.Key technologies in the new engine include: all-aluminum construction, dual overhead camshafts (DOHC), 4-valve-per-cylinder valvetrain, roller-finger follower valvetrain, continuously variable cam phasing, electronic throttle control (ETC), durable forged-steel crankshaft, piston-cooling oil jets, coolant-loss protection software, GM's Oil Life System, 32-bit microprocessor and coil-on-plug ignition.
