The Chrysler LeBaron Coupe 2.5i Turbo, produced between 1989 and 1994, represented a performance-oriented variant within the second generation of the LeBaron. Positioned as a more sporting alternative to the base models, the 2.5i Turbo aimed to attract buyers seeking a blend of style, comfort, and respectable acceleration. This coupe utilized the Chrysler’s front-wheel-drive platform, sharing its underpinnings with other K-car derivatives, but distinguished itself with a turbocharged four-cylinder engine. It was marketed primarily in North America, offering a domestic alternative to imported sporty coupes.

Powertrain & Engine Architecture
The heart of the LeBaron Coupe 2.5i Turbo was the Chrysler 2.5-liter inline-four cylinder engine. Internally designated with various codes depending on the year, this engine featured a cast iron block and an aluminum cylinder head. The key differentiating factor was the addition of a Garrett turbocharger and an intercooler, boosting power output to 155 horsepower and 284 Nm (209 lb-ft) of torque. Fuel delivery was managed by a multi-port fuel injection system, providing precise control over the air-fuel mixture. The engine utilized a single overhead camshaft (OHC) design with two valves per cylinder. The five-speed manual transmission was standard, providing drivers with full control over the engine’s power band. The transmission was a relatively conventional design, known for its durability but not particularly sporty feel.
Driving Characteristics
The 2.5i Turbo offered a noticeable performance upgrade over the naturally aspirated LeBaron models. Acceleration to 60 mph was achieved in approximately 8.1 seconds, making it a competitive performer in its class during the early 1990s. The turbocharger provided a surge of power in the mid-range, offering strong passing acceleration. However, turbo lag was present, requiring drivers to anticipate and plan ahead when overtaking. The five-speed manual transmission allowed drivers to keep the engine in its optimal power band. Handling was adequate, but the LeBaron Coupe wasn’t designed as a dedicated sports car. The front-wheel-drive layout could exhibit some understeer when pushed hard, and the suspension was tuned more for comfort than outright handling precision.
Equipment & Trim Levels
The LeBaron Coupe 2.5i Turbo typically came well-equipped for its time. Standard features included air conditioning, power windows and locks, a tilt steering wheel, and a basic sound system. Upholstery was typically cloth, although leather options were available. Optional extras included a premium sound system, sunroof, and upgraded interior trim. The interior design was typical of early 1990s American cars, with a focus on comfort and practicality rather than cutting-edge styling. The dashboard layout was straightforward and easy to use.
Chassis & Braking
The LeBaron Coupe utilized a relatively simple chassis design. Front suspension consisted of independent coil springs, while the rear suspension employed a semi-independent twist beam setup. Brakes were ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) were standard, enhancing safety and control during hard braking. Steering was rack-and-pinion with hydraulic power assistance, providing light and easy steering feel. The tires were typically 195/70R13, offering a balance of ride comfort and grip.
Market Reception & Comparison
The LeBaron Coupe 2.5i Turbo received mixed reviews from automotive critics. While the turbocharged engine was praised for its performance, some reviewers found the handling to be somewhat lackluster. Fuel economy was reasonable for a turbocharged vehicle of its era, averaging around 24.5 mpg in combined driving. Compared to other trims in the LeBaron lineup, the 2.5i Turbo offered a significant performance advantage but came at a higher price. It competed with other sporty coupes such as the Ford Probe and the Mazda MX-6, offering a domestic alternative with a different styling and driving experience.
Legacy
The Chrysler LeBaron Coupe 2.5i Turbo, while not a groundbreaking vehicle, holds a place in automotive history as a relatively affordable and accessible turbocharged coupe. The 2.5-liter turbo engine proved to be reasonably reliable, although regular maintenance was essential to prevent issues with the turbocharger and fuel injection system. Today, well-maintained examples are becoming increasingly collectible, appealing to enthusiasts who appreciate classic 1990s American cars. The LeBaron Coupe 2.5i Turbo represents a unique chapter in Chrysler’s history, showcasing the company’s willingness to experiment with forced induction technology in a mainstream vehicle.
