The Jaguar S-Type (CCX) 2.5 i V6 24V Automatic, produced between 2001 and 2007, represented a key entry point into the Jaguar lineup during that period. Positioned as a more accessible alternative to the higher-performance and more luxurious variants, the 2.5-liter V6 model aimed to broaden the S-Type’s appeal. It was part of the CCX generation, which itself was a significant refresh of the original S-Type introduced in 1999, blending classic Jaguar styling cues with modern engineering. This variant competed with mid-size luxury sedans from German manufacturers like BMW and Mercedes-Benz, offering a distinctly British alternative.

Powertrain & Engine Architecture
The heart of the S-Type 2.5 i was the AJ25 V6 engine. This 2.5-liter, naturally aspirated engine featured a 60-degree V-angle and utilized a dual overhead camshaft (DOHC) design with four valves per cylinder. The engine employed multi-port fuel injection, delivering fuel directly into the intake ports. The AJ25 was known for its relatively smooth operation and decent power output for its displacement. The automatic transmission was a six-speed unit, providing reasonably quick shifts, though not as sporty as the manual options available on other S-Type models. This transmission was chosen to provide a comfortable and refined driving experience, aligning with the S-Type’s overall character.
Driving Characteristics
The 200 horsepower and 180.7 lb-ft of torque delivered by the 2.5-liter V6, coupled with the six-speed automatic, resulted in a 0-60 mph time of around 9.4 seconds and a top speed of 139.81 mph. While not particularly quick by modern standards, it offered adequate performance for everyday driving and highway cruising. The automatic transmission, while smooth, did slightly diminish the engine’s responsiveness compared to the manual transmission options. Gear ratios were tuned for comfort and fuel efficiency rather than outright acceleration. The rear-wheel-drive configuration provided a balanced feel, though it lacked the dynamic agility of some of its competitors.
Equipment & Trim Levels
The 2.5 i typically came standard with features like leather upholstery, climate control, power windows and mirrors, and an audio system. Optional extras included a sunroof, upgraded audio systems, and wood veneer trim. The trim level generally sat in the mid-range of the S-Type lineup, offering a good balance of features and affordability. It was a step up from the base models but lacked the more luxurious appointments found in the 3.0-liter and 4.2-liter variants.
Chassis & Braking
The S-Type utilized a double wishbone suspension setup at both the front and rear, providing a comfortable ride quality. Ventilated disc brakes were fitted on all four wheels, offering adequate stopping power. Anti-lock Braking System (ABS) was standard. The suspension was tuned for comfort, prioritizing a smooth ride over sharp handling. The 2.5 i models typically featured slightly smaller tires (205/60 R16) compared to the higher-performance variants, contributing to the softer ride.
Market Reception & Comparison
The S-Type 2.5 i was generally well-received as an accessible entry point into the Jaguar brand. Critics praised its comfortable ride, refined interior, and classic Jaguar styling. However, some noted that the 2.5-liter engine felt somewhat underpowered compared to the larger engines available. Fuel economy was reasonable for a vehicle in its class, averaging around 22.8 US mpg combined. Compared to the 3.0-liter model, the 2.5 i offered lower running costs but sacrificed performance. The 4.2-liter models provided significantly more power but came at a higher price point.
Legacy
The AJ25 engine, while not as celebrated as Jaguar’s larger V8s, proved to be a relatively reliable powerplant. The six-speed automatic transmission also generally held up well over time. Today, the S-Type 2.5 i represents an affordable way to experience Jaguar ownership. Common issues include age-related wear and tear on suspension components and potential for oil leaks. However, with proper maintenance, these vehicles can provide years of reliable service. The S-Type 2.5 i remains a popular choice for enthusiasts seeking a classic British luxury sedan at a reasonable price.
