Technical Specifications

Introduction

The 2015-2018 Jaguar XJ 5.0 V8 Automatic represented the pinnacle of the X351 series, a generation that aimed to revitalize Jaguar’s flagship sedan. Building upon the aluminum-intensive construction introduced with the X351 in 2009, the facelifted model offered a more refined driving experience, updated technology, and a more luxurious interior. This variant, with its potent supercharged V8, was targeted at discerning buyers who prioritized performance and prestige. The XJ competed directly with established German rivals, offering a unique blend of British style and dynamic capability.

Powertrain & Engine Architecture

At the heart of the XJ 5.0 V8 is Jaguar’s AJ126 engine, a 5.0-liter supercharged V8. This engine, a descendant of Jaguar’s long line of V8s, utilizes a sixth-generation Eaton supercharger to deliver substantial power and torque. The engine features direct fuel injection, a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, and variable valve timing (VVT) on both intake and exhaust sides. The engine code, 508PS, denotes its power output in metric horsepower. The eight-speed automatic transmission, sourced from ZF, provides smooth and responsive gear changes. This transmission is known for its efficiency and ability to handle the engine’s considerable torque. The transmission features a wide gear ratio spread, optimizing both acceleration and fuel economy.

Driving Characteristics

The XJ 5.0 V8 Automatic delivers exhilarating performance. The supercharged V8 provides instant throttle response and strong acceleration throughout the rev range. The 0-60 mph sprint is achieved in approximately 4.9 seconds, and the car feels remarkably composed at high speeds. The eight-speed automatic transmission contributes to a refined driving experience, seamlessly shifting gears and providing ample power for overtaking maneuvers. Compared to the XJ’s other engine options, such as the 3.0-liter V6 or the 3.0-liter turbodiesel, the V8 offers a significantly more powerful and engaging driving experience. While the V6 models prioritize fuel efficiency and the diesel models offer strong low-end torque, the V8 is focused on delivering a thrilling and dynamic performance.

Equipment & Trim Levels

The XJ 5.0 V8 Automatic typically came equipped with a high level of standard features. These included leather upholstery, heated and ventilated front seats, a premium sound system, a touchscreen infotainment system, and a comprehensive suite of safety features. Optional extras included rear-seat entertainment, a panoramic sunroof, and various trim enhancements. The interior was characterized by its luxurious materials, elegant design, and attention to detail. The XJ offered a range of customization options, allowing buyers to personalize their vehicles to their specific tastes.

Chassis & Braking

The XJ’s chassis is built around an aluminum monocoque structure, contributing to its relatively low weight. The suspension system features double wishbones at both the front and rear, providing a comfortable ride and precise handling. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and control. The XJ’s suspension is tuned to provide a balance between comfort and handling, offering a refined driving experience without sacrificing agility.

Market Reception & Comparison

The Jaguar XJ 5.0 V8 Automatic was generally well-received by automotive critics. It was praised for its powerful engine, luxurious interior, and refined driving experience.
