A series designation used on Chrysler vehicles to denote a special sporting nature. The acronym, according to sources within Chrysler Corp itself, stands for Touring Sport injection. Vehicles with this
factory designation were considered to be Chrysler company's most sporting of any particular model. TSi models released in America included the Chrysler Conquest, Eagle Talon, Jeep Grand Cherokee, Eagle Vision, and most recently the Chrysler Sebring TSi.
Some claim that the "T" character in the acronym stands for "Turbo" or "Turbocharged". While Chrysler does not deny or confirm this, it should be noted that out of all the TSi models released, only two were actually fitted with factory turbochargers, those being the Conquest and the Talon. While the character "i" in this series does stand for "injection", it should be noted that all these vehicles were fuel injected, and the "i" character indicates an increased
performance value through some form of additional engine tuning, be it
electronic,
forced induction, or larger displacement.
