The Jaguar S-Type (CCX) 2.5 i V6 24V, produced between 2001 and 2007, represented a key iteration of Jaguar’s mid-size luxury sedan. Positioned as an entry-level offering within the S-Type range, it aimed to broaden the model’s appeal by providing a more accessible price point while retaining the core Jaguar experience. This variant utilized the AJ25 V6 engine, a significant departure from the inline-six engines previously favored by Jaguar, and was offered with both manual and automatic transmission options. The CCX designation refers to the updated chassis and bodywork introduced during this generation.

Powertrain & Engine Architecture
The heart of the S-Type 2.5 i is the AJ25 V6 engine. This 2.5-liter, 24-valve engine represented a significant shift for Jaguar, moving away from the traditional inline-six configuration. The AJ25 featured a 60-degree V-angle, contributing to a more compact engine bay layout. It employed multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain, optimizing airflow for improved performance. The engine code, AJ25, is crucial for identifying specific parts and service information. The 200 horsepower output was achieved at 6800 rpm, while peak torque of 245 Nm (180.7 lb-ft) arrived at 4000 rpm. The engine’s relatively high compression ratio of 10.5:1 demanded premium fuel for optimal performance and to prevent knocking. The 5-speed manual transmission offered a more engaging driving experience, while the optional automatic provided convenience, though at the expense of some performance.
Driving Characteristics
The 2.5 i V6 with the manual transmission offered a reasonably spirited driving experience for its class. Acceleration to 60 mph took approximately 8.2 seconds, and the car could reach a top speed of 141.67 mph. However, compared to the higher-output 3.0-liter and 4.0-liter V8 variants, the 2.5 i felt noticeably less powerful, particularly during overtaking maneuvers. The automatic transmission, while smooth, further dulled acceleration. The gear ratios were tuned for a balance of fuel economy and drivability, but the engine often felt strained when pushed hard. The rear-wheel-drive configuration provided a balanced feel, but the relatively soft suspension setup prioritized comfort over sharp handling.
Equipment & Trim Levels
The 2.5 i typically served as the entry point to the S-Type range. Standard equipment included air conditioning, power windows and locks, a CD player, and alloy wheels. Interior upholstery was typically cloth, though leather was available as an option. Higher trim levels added features such as wood veneer trim, upgraded audio systems, and heated seats. Optional extras included a sunroof, navigation system, and premium leather upholstery. The dashboard layout was consistent across the S-Type range, featuring a classic Jaguar design with analog gauges and a wood-trimmed center console.
Chassis & Braking
The S-Type CCX utilized a double wishbone suspension system at both the front and rear, providing a comfortable ride. The 2.5 i models typically featured ventilated disc brakes on all four wheels, offering adequate stopping power. Anti-lock Braking System (ABS) was standard. Stabilizer bars were fitted front and rear to reduce body roll during cornering. The chassis was designed to provide a balance between comfort and handling, leaning more towards the former. The weight distribution was reasonably well-balanced, contributing to predictable handling characteristics.
Market Reception & Comparison
The S-Type 2.5 i was generally well-received as an affordable entry point into the Jaguar brand. Critics praised its comfortable ride and stylish interior, but noted its lack of outright performance compared to the V8 models. Fuel economy was considered reasonable for a luxury sedan of its size. Compared to the 3.0-liter variant, the 2.5 i offered lower running costs but sacrificed performance. The 4.0-liter V8 models provided significantly more power but came with a higher price tag and increased fuel consumption. Reliability was generally good, although some owners reported issues with the automatic transmission and electrical components.
Legacy
The AJ25 V6 engine proved to be a reliable powerplant, and many S-Type 2.5 i models remain on the road today. The 5-speed manual transmission is generally considered more durable than the automatic. In the used car market, the 2.5 i represents a relatively affordable way to experience Jaguar ownership. However, potential buyers should be aware of potential maintenance costs associated with a luxury vehicle of this age, including suspension components and electrical systems. The S-Type 2.5 i, while not the most powerful or prestigious variant, played a crucial role in expanding the S-Type’s appeal and bringing the Jaguar brand to a wider audience.
