The Chrysler Imperial, a full-size luxury sedan, enjoyed a resurgence in the late 1980s and early 1990s, marking its return after a hiatus of over a decade. The 1990-1993 model years represent the final chapter of this iteration, building upon the success of its predecessors. These Imperials were built on Chrysler's "C" platform, shared with the Dodge Dynasty and the Chrysler New Yorker, but offered a distinctly more luxurious experience. Distinguished by its upright grille with prominent vertical chrome bars and a large, elegant hood, the Imperial exuded an air of classic sophistication. It boasted a spacious interior, featuring plush leather seating, real wood trim, and ample legroom, offering a comfortable and refined driving experience. Powering the Imperial was a 3.3-liter, fuel-injected V6 engine, paired with a four-speed automatic transmission. While not particularly sporty, it provided adequate power for comfortable highway cruising and city driving. Notably, the 1990 Imperial introduced an optional 3.8-liter V6 engine, offering a significant boost in performance. Although not as technically advanced as some of its competitors, the Imperial offered a compelling blend of comfort, luxury, and reliability. It served as a testament to Chrysler's commitment to crafting high-quality, full-size sedans that cater to discerning drivers seeking a stately and comfortable driving experience. However, despite its strengths, the Imperial faced stiff competition from luxury car makers like Cadillac and Lincoln, ultimately leading to its discontinuation after the 1993 model year.
