During its entire production period the Acura TSX offered buyers two distinct powertrain configurations which included both a K24 2.4-liter inline-four and a J35 3.5-liter V6 engine. Choosing between the available powerplants has generated an ongoing discussion to determine which engine captures the true essence of the TSX. The common TSX engine K24 delivers both high-revving performance and fuel efficiency through its reduced weight which enhances the vehicle's handling agility. Supporters of this engine value its VTEC technology which they believe captures the TSX's sporty nature. The second generation J35 V6 engine delivers substantially higher power and torque while creating a luxurious driving experience with effortless performance. The V6 engine is the best match for the TSX's designation as a premium sports sedan in supporters' opinions. The debate encompasses discussions about the performance and efficiency balance along with engine type comparisons between naturally aspirated and turbocharged systems while determining car personality through engine choice.
