The Lincoln LS 3.9 V8, produced from 1998 to 2000, represented a significant departure for the Lincoln brand, aiming to offer a more sporting and refined experience than traditional American luxury sedans. Positioned as an entry-level luxury vehicle, it was Lincoln’s attempt to compete with European rivals like the BMW 5 Series and Mercedes-Benz E-Class. The LS was built on the DEW98 platform, shared with the Jaguar S-Type, a result of Ford’s ownership of both brands. This particular variant, equipped with the 3.9-liter V8 engine and a four-speed automatic transmission, was the top-tier offering in the LS lineup during its initial production run, providing a balance of performance and comfort.

Powertrain & Engine Architecture
The heart of the Lincoln LS 3.9 was the 99A engine, a 3.9-liter (3950 cc) naturally aspirated V8. This engine featured a 60-degree V-angle, a cast iron block with aluminum cylinder heads, and dual overhead camshafts (DOHC) operating four valves per cylinder. The engine utilized a multi-port fuel injection system, delivering fuel directly to each intake port. The 99A engine was known for its smooth power delivery and relatively high specific output for a naturally aspirated engine of its era. The four-speed automatic transmission, a Ford 4R70W unit, was specifically tuned for the LS to provide refined shifts and a comfortable driving experience. While not a particularly advanced transmission by modern standards, it was durable and well-suited to the engine’s torque characteristics.
Driving Characteristics
The 3.9L V8 and automatic transmission combination delivered a respectable 0-60 mph time of around 7.3 seconds. The automatic transmission, while smooth, did result in some power loss compared to the available five-speed manual transmission offered on some LS models. The gear ratios were optimized for cruising comfort rather than outright acceleration. The rear-wheel-drive configuration contributed to a balanced feel, although the LS wasn’t as overtly sporty as some of its European competitors. The suspension, tuned for comfort, provided a smooth ride, but body roll was noticeable during aggressive cornering. The engine’s torque peak at 4250 rpm provided ample power for everyday driving and passing maneuvers.
Equipment & Trim Levels
The Lincoln LS 3.9 V8 typically came standard with features such as leather upholstery, power-adjustable front seats, a premium sound system, automatic climate control, and alloy wheels. Optional extras included a navigation system, heated seats, a sunroof, and upgraded interior trim. The LS aimed for a luxurious experience, with a focus on comfort and convenience features. The interior design was generally well-regarded, although some critics found it to be somewhat conservative compared to the more avant-garde interiors of European rivals.
Chassis & Braking
The LS featured an independent front suspension with coil springs and an independent rear suspension, also utilizing coil springs. The braking system consisted of ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) were standard. The chassis was designed to provide a balance between ride comfort and handling. While the suspension was tuned for comfort, it offered adequate control and stability. The steering was hydraulic power-assisted rack and pinion, providing a reasonably responsive feel.
Market Reception & Comparison
The Lincoln LS 3.9 V8 was generally well-received by automotive critics, who praised its smooth engine, comfortable ride, and luxurious interior. However, it was often criticized for not being as engaging to drive as its European competitors. Fuel economy was also a concern, with the 3.9L V8 consuming approximately 18 mpg in the city and 26 mpg on the highway. Compared to the base 3.0L V6 LS, the 3.9 V8 offered significantly more power and a more refined driving experience, but at a higher price point. The V8 also required more expensive maintenance, particularly oil changes and spark plug replacements. Compared to the later 4.6L V8 models, the 3.9L offered a slightly more manageable size and weight, contributing to a more balanced feel.
Legacy
The Lincoln LS, despite its relatively short production run, remains a popular choice among enthusiasts seeking a comfortable and well-equipped American luxury sedan. The 3.9L V8 engine, while not known for exceptional reliability, is generally considered durable if properly maintained. Common issues include oil leaks and occasional sensor failures. Today, the LS 3.9 V8 can be found on the used car market at relatively affordable prices, making it an attractive option for those seeking a classic American luxury experience. Parts availability is generally good, although some specific components may be difficult to find. The LS’s attempt to bridge the gap between American luxury and European sportiness, while not entirely successful in its time, paved the way for future Lincoln models to embrace a more dynamic driving experience.
