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.
