Jaguar XKR-S Convertible: In-Depth Specs And Performance

The Jaguar XKR-S Convertible stands as a pinnacle of grand touring excellence, combining ferocious performance with British sophistication. This drop-top variant of Jaguar’s flagship XK model delivers 550 horsepower from a supercharged 5.0-liter V8, propelling it to a governed top speed of 186 mph while maintaining everyday usability. Reviewers praise its balance of explosive acceleration, composed handling, and luxurious comfort, making it ideal for both high-speed cruises and spirited drives.

Engineering a Beast: The Supercharged Heart

At the core of the XKR-S Convertible lies Jaguar’s 5.0-liter AJ-V8 engine, enhanced with a Roots-type supercharger. This setup produces 542-550 bhp (sources vary slightly on exact figures) and a staggering 502 lb-ft of torque available from just 2,500 rpm up to 5,500 rpm. The supercharger ensures seamless power delivery without turbo lag, providing instant response that reviewers describe as a ’roundhouse of torque’ slamming into the driver.

Power routes through a six-speed automatic transmission with paddle shifters to the rear wheels, augmented by an electronic active rear differential. This allows efficient power deployment, even under hard acceleration out of corners. Jaguar claims a 0-60 mph sprint in 4.2 seconds, but independent tests suggest it could dip into the low 4-second range or even 3.7 seconds under optimal conditions. The exhaust system, with active flaps, unleashes a deep, refined growl above 4,000 rpm, evolving into a symphony at full throttle.

• Engine Specs: 5.0L Supercharged V8, 542-550 bhp, 502 lb-ft torque
• Transmission: 6-speed automatic with paddles
• Drivetrain: Rear-wheel drive with active differential
• Top Speed: 186 mph (electronically limited)
• 0-60 mph: ~4.2 seconds (tested quicker)

Aggressive Styling That Turns Heads

The XKR-S Convertible’s design evolves the XK’s elegant lines into something more menacing and purposeful. Aerodynamic enhancements include front nacelles to channel air over the wheels, a deeper chin spoiler, widened rocker panels, a restyled rear diffuser, and a prominent carbon-fiber rear wing. These features not only aid high-speed stability but also create an imposing presence. The car sits 0.4 inches lower than the standard XKR, shod in 20-inch smoke-colored forged wheels wrapped with Pirelli P Zero tires (255/35ZR-20 front, 295/30ZR-20 rear).

Inside, the cabin exudes luxury with textured aluminum trim, aggressive yet comfortable sport seats, and ample front legroom. The fabric roof deploys or stows in under 20 seconds, adding just 88 pounds to the coupe’s weight thanks to the rigid aluminum chassis—no extra bracing was needed. Rear seats exist but are comically small, best suited for bags rather than passengers.

Dynamic Mastery: Handling and Ride Quality

Despite its grand tourer roots, the XKR-S Convertible punches above its weight dynamically. Front and rear springs are 28% stiffer than the standard XKR, paired with adaptive dampers that adjust in real-time. In comfort mode, it soaks up bumps on highways, making long-distance drives effortless—even after 200 miles, drivers report eagerness for more. Switch to Dynamic mode, and the suspension firms up, throttle sharpens, and transmission holds gears longer for track-like responsiveness.

Steering is precise and communicative, with excellent feedback from the chassis. The active differential and updated Dynamic Stability Control (DSC) ensure the 550 hp stays planted, though pushing limits reveals its rear-drive nature—capable of sudden snaps if provoked. Body flex is minimal for a convertible, thanks to Jaguar’s lightweight aluminum architecture. Tire noise is noticeable, but grip levels are tremendous, enabling 120 mph cruises that feel utterly composed.

Reviewers highlight its ‘agile cat’ demeanor: balanced, grippy, and fun, though its size shows in tight turns where front tires scrub slightly.

Everyday Luxury Meets Supercar Pace

Beyond the specs, the XKR-S excels as a usable daily driver. The cabin offers plentiful storage, adjustable steering, and snug yet supportive seats. Ride comfort surprises with its suppleness over rough roads, and the low-slung stance handles speed bumps cautiously but capably. Fuel economy? Expect mid-teens mpg in mixed driving—not a priority for this beast.

It’s a velvet-sheathed sledgehammer: innocuous at low speeds, devastating when unleashed. The power feels manageable, with high-speed stability that belies its convertible form.

Ownership Considerations

Priced around $138,000 new in 2012, the XKR-S targeted buyers seeking Bentleys’ luxury with Porsche-like pace. Maintenance on the supercharged V8 demands care, but Jaguar’s engineering proves durable. Today, used examples offer supercar thrills at fraction of original cost—ideal for enthusiasts.

• Pros: Explosive power, stunning looks, comfortable GT ride, solid chassis
• Cons: Tight rear seats, tire noise, high running costs, size in tight spaces
