Technical Specifications

INTRODUCTION

The Jaguar XK R-S Convertible, launched in 2011 as part of the X150 facelift, was the most potent version of the XK convertible available. Built on the X150 platform, which also underpinned the XKR, the R-S took performance to a new level. It was designed to compete with high-performance grand tourers from brands like Porsche and Aston Martin, offering a unique blend of British luxury, exhilarating performance, and open-air driving enjoyment. Production concluded in 2014, making it a relatively rare and sought-after model.

Powertrain & Engine Architecture

At the heart of the XK R-S Convertible lies Jaguar’s 5.0-liter supercharged V8 engine, designated the AJ133. This engine, a cornerstone of Jaguar performance for many years, was extensively upgraded for the R-S model. Producing 550 horsepower at 6000-6500 rpm and 680 Nm (501.54 lb-ft) of torque between 2500-5500 rpm, the engine featured a sixth-generation Eaton supercharger, optimized for increased airflow and efficiency. Direct fuel injection and a sophisticated engine management system further enhanced performance and responsiveness. The engine’s architecture is a 90-degree V8 with double overhead camshafts (DOHC) and four valves per cylinder. The R-S exclusively utilized a six-speed automatic transmission, calibrated for quicker shifts and more aggressive downchanges. This transmission was not the latest available at the time, but it was robust and well-suited to the engine’s power output.

Driving Characteristics

The XK R-S Convertible delivered a truly engaging driving experience. The supercharged V8 provided immense power and torque, resulting in blistering acceleration – 0 to 60 mph in approximately 4.2 seconds and a limited top speed of 186 mph. The six-speed automatic transmission, while not as quick as some dual-clutch alternatives, offered smooth and responsive shifts, particularly in Sport mode. The R-S benefited from a revised suspension setup, including stiffer springs and dampers, and a quicker steering ratio, resulting in improved handling and body control. While the added power and stiffer suspension made it less comfortable than the standard XK, the R-S offered a thrilling and rewarding driving experience, especially on winding roads. The exhaust note was also significantly more aggressive, adding to the car’s sporting character.

Equipment & Trim Levels

The XK R-S Convertible came generously equipped as standard. Interior features included premium leather upholstery, heated and ventilated front seats, a high-end audio system, and a touchscreen infotainment system. Unique R-S badging adorned the interior and exterior, distinguishing it from other XK models. Standard exterior features included a distinctive body kit with aerodynamic enhancements, including a front splitter, side sills, and a rear spoiler. Optional extras included a panoramic sunroof, adaptive cruise control, and various customization options for interior trim and paint colors. The R-S was positioned as the top-of-the-line XK Convertible, and its price reflected its performance and exclusivity.

Chassis & Braking

The XK R-S Convertible’s chassis was based on the X150 platform, a lightweight aluminum monocoque construction. The suspension featured double wishbones at both the front and rear, with transverse stabilizers to reduce body roll. The braking system consisted of ventilated discs on all four wheels, with larger front discs (380mm) and rear discs (376mm) compared to the standard XK. The R-S also included an advanced anti-lock braking system (ABS) and electronic stability control (ESC) to enhance safety and control. The tires were high-performance Pirelli P Zeros, sized 255/35 R20 at the front and 295/30 R20 at the rear, providing excellent grip and handling.

Market Reception & Comparison

The Jaguar XK R-S Convertible was generally well-received by automotive critics. It was praised for its powerful engine, engaging driving dynamics, and luxurious interior. However, some critics noted that the six-speed automatic transmission felt dated compared to newer transmissions offered by competitors. Compared to the standard XK and XKR, the R-S offered a significant performance upgrade, but at a higher price point. Fuel economy was predictably poor, averaging around 19.1 US mpg in combined driving. Reliability was generally good, although the complex supercharged engine and advanced electronics required careful maintenance.

Legacy

The Jaguar XK R-S Convertible remains a desirable and collectible grand tourer. Its combination of performance, luxury, and exclusivity has ensured its enduring appeal. While the X150 platform has been replaced by the F-Type, the XK R-S continues to offer a unique driving experience. The 5.0-liter supercharged V8 engine is known for its robustness, but regular maintenance is essential to prevent potential issues. On the used car market, well-maintained examples of the XK R-S Convertible command a premium price, reflecting its status as the ultimate expression of the X150 XK.
