This engine was Chrysler's first 60° V6 engine designed and built in-house for front wheel drive vehicles, and their first V6 not based on a V8. It was designed as a larger, more powerful option to the Mitsubishi 3.0 V6 in the minivans and debuted in 1990.
The engine has been produced in two major variants differing by their piston displacement: a 3.3 l (201 cu in) and a 3.8 l (232 cu in). The 3.3 was dropped after 2010 with the Chrysler minivans, and the 3.8 was dropped after 2011 with the Jeep Wrangler, ending 21 years in production.
The original 3.3 engine, as well as the larger 3.8, are pushrod engine designs. The 3.3 was introduced in 1990 and was joined in 1991 by the 3.8. Production on the 3.3 was stopped in 2010 while the 3.8 remained in production until May 2011 in Trenton, Michigan for the Jeep Wrangler. Both use a cast iron block and aluminum heads.
The first of the family, the 3.3 liter engine's actual piston displacement is 3,301 cc (201 cu in) with a 93 mm (3.7 in) bore and 81 mm (3.2 in) stroke. In 1994, the 3.3 got a 12 hp (8.9 kW) increase in power to 162 hp (121 kW) due to a new air intake. In 2001, the engine was fitted with a variable intake control system which boosted output to 180 hp (130 kW) at 5000 rpm and 210 lb·ft (285 N·m) at 4000 rpm. The engine was designed for transverse applications in Chrysler's minivans, but was also used in a longitudinal front-wheel-drive setup on 1993-1997 LH platform cars. It was last used in 2010 for Chrysler minivans before the introduction of the new 3.6 L Pentastar engine for the 2011 model year.
