The Lincoln LS 3.9 i V8 32V, produced from 2003 to 2006, represented the top-tier performance offering within the first generation (2000-2006) of the LS model line. Positioned as a direct competitor to entry-level luxury sedans from European manufacturers like BMW and Mercedes-Benz, the LS aimed to deliver American comfort and refinement with a sporting edge. This particular variant, equipped with the 3.9-liter V8 engine and a five-speed automatic transmission, served as the flagship model, offering a significant step up in power and performance compared to the base 3.0-liter V6 versions.

Powertrain & Engine Architecture
The heart of the LS 3.9 i was the 99A engine, a 3.9-liter (3950 cc) naturally aspirated V8. This engine was based on the Jaguar AJ-V8 design, acquired by Ford in 1989 with the purchase of Jaguar. The Lincoln version featured a 10.75:1 compression ratio and utilized multi-port fuel injection. The dual overhead camshafts (DOHC) operated four valves per cylinder, contributing to its respectable power output. The engine was longitudinally mounted in the front of the vehicle, driving the rear wheels. The five-speed automatic transmission, while providing smooth shifts, wasn’t known for being particularly sporty or quick to respond. It was calibrated more for comfort and refinement than aggressive performance.
Driving Characteristics
The LS 3.9 i offered a noticeably more engaging driving experience than its V6 counterparts. The 284 horsepower and 286 lb-ft of torque provided brisk acceleration, with a 0-60 mph time of around 6.5 seconds. While not a sports car, the V8 delivered ample power for highway passing and merging. The automatic transmission, while smooth, did exhibit some hunting for the right gear, especially during spirited driving. The gear ratios were tuned for cruising comfort rather than maximizing acceleration. The rear-wheel-drive configuration contributed to a balanced feel, although the LS wasn’t as nimble as some of its European rivals.
Equipment & Trim Levels
The LS 3.9 i typically came well-equipped, reflecting its position as the premium trim level. Standard features included leather upholstery, wood trim, a premium sound system (often a THX II certified system), automatic climate control, and power-adjustable front seats with memory functions. Optional extras included a navigation system, heated and cooled front seats, and a sunroof. The interior design emphasized luxury and comfort, with a focus on high-quality materials and a refined aesthetic.
Chassis & Braking
The LS utilized an independent coil spring suspension at all four corners. The front suspension featured stabilizer bars to reduce body roll. The rear suspension, while also coil-sprung, employed a multi-link design. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) were standard. The chassis was designed to provide a comfortable ride while maintaining reasonable handling characteristics. The steering was hydraulic power-assisted rack and pinion, offering a good balance of feel and ease of use.
Market Reception & Comparison
Critics generally praised the LS 3.9 i for its powerful engine, comfortable ride, and luxurious interior. However, it often faced criticism for its somewhat bland styling and the automatic transmission’s lack of responsiveness. Compared to the 3.0-liter V6 models, the 3.9 i offered a significant performance upgrade, but at a higher price point. Fuel economy was also lower with the V8, averaging around 16 mpg in the city and 26 mpg on the highway. The LS 3.9 i competed directly with vehicles like the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6, but often struggled to match their brand prestige and driving dynamics.
Legacy
The Lincoln LS, while not a commercial blockbuster, represented a bold attempt by Ford to compete in the luxury sedan segment. The 3.9-liter V8 engine proved to be relatively reliable, although routine maintenance, such as timing chain tensioner replacements, is crucial as these vehicles age. Today, the LS 3.9 i can be found on the used car market at relatively affordable prices. It appeals to buyers seeking a comfortable, well-equipped, and reasonably powerful American luxury sedan with a unique character. While it may not offer the same level of performance or prestige as its European rivals, the LS 3.9 i provides a compelling alternative for those looking for a distinctive and value-packed vehicle.
