Technical Specifications

INTRODUCTION

The Jaguar XJ X358 3.5 V8 Automatic, produced between 2007 and 2009, represents a refined iteration of Jaguar’s long-standing XJ luxury sedan. Built on the X358 platform, this model aimed to deliver a compelling blend of performance, comfort, and technology. The 3.5-liter V8 engine, coupled with a six-speed automatic transmission, provided a smooth and capable driving experience, making it a popular choice for buyers seeking a luxurious grand tourer. Within the X358 range, this variant served as a sweet spot, offering a significant step up in performance from the base 3.0-liter models while remaining more accessible than the supercharged 4.2-liter options.

Powertrain & Engine Architecture

At the heart of the XJ 3.5 V8 lies the AJ-V8 engine, a naturally aspirated 3.5-liter (3555cc) V8. This engine, a descendant of the Ford-Jaguar collaboration, features a 60-degree V-angle and utilizes multi-port fuel injection. The engine code is typically identified as AJ35. It produces 258 horsepower at 6250 rpm and 335 Nm (247 lb-ft) of torque at 4200 rpm. The engine employs a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its smooth power delivery. The six-speed automatic transmission, sourced from ZF, is a key component of the powertrain. This transmission is known for its smooth shifts and responsiveness, enhancing the overall driving experience. It features adaptive shift programming, adjusting shift points based on driving style and conditions.

Driving Characteristics

The XJ 3.5 V8 Automatic delivers a characteristically smooth and refined driving experience. While not as overtly sporty as the supercharged models, the 3.5-liter V8 provides ample power for comfortable cruising and confident overtaking. Acceleration from 0-60 mph takes approximately 7.2 seconds, and the car boasts a top speed of 146 mph. The automatic transmission contributes to the ease of driving, offering seamless gear changes. Compared to the manual transmission options (available on other XJ variants), the automatic prioritizes comfort and convenience over driver engagement. The gear ratios are tuned for relaxed highway cruising, with a focus on minimizing engine noise and maximizing fuel efficiency. However, it doesn’t feel sluggish, offering sufficient power for spirited driving when needed.

Equipment & Trim Levels

The XJ 3.5 V8 Automatic typically came well-equipped as standard. Interior features included leather upholstery, wood veneer trim, and a premium audio system. Standard amenities also included automatic climate control, power-adjustable seats with memory function, and a sunroof. Optional extras included upgraded leather packages, rear seat entertainment systems, and advanced navigation systems. Trim levels varied slightly depending on the market, but generally, the 3.5 V8 sat in the mid-range of the XJ lineup. It offered a step up in luxury and features compared to the base models, but lacked some of the more exclusive options available on the supercharged variants.

Chassis & Braking

The XJ X358 benefited from significant advancements in chassis technology, including extensive use of aluminum in its construction. This resulted in a lighter and more rigid body, improving handling and ride quality. The suspension system features double wishbones at both the front and rear, along with a transverse stabilizer bar to reduce body roll. Braking duties are handled by ventilated discs on all four wheels, coupled with an Anti-lock Braking System (ABS) for enhanced safety. The braking system provides ample stopping power, and the ABS helps maintain control during emergency braking situations. The steering is a hydraulic rack and pinion system, offering precise and responsive steering feel.

Market Reception & Comparison

The XJ 3.5 V8 Automatic was generally well-received by automotive critics. It was praised for its comfortable ride, refined engine, and luxurious interior. Critics noted that while it wasn’t the fastest XJ variant, it offered a compelling balance of performance and luxury at a more accessible price point. Compared to the 3.0-liter models, the 3.5 V8 provided a noticeable improvement in performance. Compared to the supercharged 4.2-liter models, it offered a similar level of luxury but with slightly less power and a lower price tag. Fuel economy, while not exceptional, was reasonable for a luxury sedan of its size and performance, averaging around 22 mpg combined.

Legacy

The Jaguar XJ X358 3.5 V8 Automatic has proven to be a relatively reliable vehicle, particularly when properly maintained. The AJ-V8 engine is known for its durability, and the ZF six-speed automatic transmission is also considered to be robust. However, like any luxury vehicle, it requires regular maintenance to prevent issues. Common maintenance items include oil changes, coolant flushes, and inspection of suspension components. On the used car market today, the XJ X358 3.5 V8 represents a good value for buyers seeking a luxurious and refined grand tourer. It offers a classic Jaguar experience at a relatively affordable price, making it a popular choice among enthusiasts and collectors.
