Chrysler's TC by Maserati was a "Q" body based on a modified second generation Chrysler K platform jointly developed by Chrysler and Maserati as a grand tourer and introduced at the 1986 Los Angeles Auto Show. After two years of development delays, the TC became available in late-1988 and a total of 7,300 units were manufactured in Milan, Italy through 1990. All cars sold as 1991 models were manufactured in 1990. The 1989 TC used a slightly detuned 160 bhp... (119 kW; 162 PS) Daytona-spec turbocharged 2.2 L straight-4. This intercooled version, known as the Turbo II, was coupled to an A413 three-speed automatic transaxle. The Turbo II was replaced by a Mitsubishi-sourced 3.0 L 141 bhp (105 kW; 143 PS) V6 engine for the 1990 and 1991 model years, with the automatic transaxle being upgraded to a four-speed A604 unit. 500 cars were built with an optional drivetrain consisting of a Getrag manual transmission and a 16-valve head version of the 2.2 L. This engine is often called the "Maserati" engine because it was built by Maserati and has a Maserati-branded cast valve cover.
