The 2004 Acura TL boasts a formidable 3.2-liter V6 engine, a refined powerhouse built upon Acura’s advanced engineering. This engine delivers an impressive 270 horsepower and 238 lb-ft of torque, significantly surpassing its predecessors, the 2003 Acura 3.2 TL (225 hp and 216 lb-ft) and even the 2003 Acura 3.2 TL Type S (260 hp and 232 lb-ft). Remarkably, despite the power increase, the 2004 TL maintains the same EPA-estimated fuel efficiency as the previous generation when equipped with the Sequential SportShift automatic transmission. Furthermore, it meets the stringent CARB LEV-2 ULEV emissions standards.
Performance and Innovation: The 2004 Acura TL Type S Engine
A significant advancement for the TL in 2004 was the introduction of an available 6-speed manual transmission at no additional cost. This transmission, featuring short throws, closely spaced gear ratios, and slightly shorter overall gearing, caters to driving enthusiasts seeking maximum performance and engagement. This manual transmission variant also includes a helical gear-type limited-slip differential as standard equipment, enhancing grip and stability during hard acceleration.
