Jaguar XFR Speed Pack: 174 MPH Upgrade And Key Insights

The Jaguar XFR Speed Pack represents a pinnacle of engineering refinement for enthusiasts craving more from their high-performance luxury sedan. This optional upgrade transforms the already formidable XFR into a machine capable of reaching 174 mph, all while maintaining the brand’s signature blend of elegance and power. Without increasing the engine’s output, Jaguar focused on calibration, aerodynamics, and chassis tweaks to deliver a more exhilarating drive.

Powertrain Ref inements for Higher Speeds

At the heart of the XFR lies a supercharged 5.0-liter V8 engine producing 510 horsepower and 470 lb-ft of torque. The Speed Pack doesn’t boost these figures but optimizes the engine mapping and the 8-speed ZF automatic transmission to support the elevated top speed. Previously limited to 155 mph, the electronically governed maximum now extends to 174 mph (280 km/h), allowing the sedan to stretch its legs on permissive roads.

This recalibration ensures smoother power delivery at extreme velocities. Paired with Intelligent Stop/Start technology, the setup improves EU combined cycle efficiency by 11% and reduces emissions by over 8%, striking a balance between thrill and responsibility.

Aerodynamic Enhancements for Stability

Visual and functional upgrades define the Speed Pack’s exterior. A prominent front aero splitter channels airflow more effectively, reducing lift and enhancing high-speed stability. Complementing this is a distinctive rear wing that generates downforce, keeping the rear planted during aggressive maneuvers.

These subtle yet purposeful changes maintain the XFR’s sleek silhouette while improving the coefficient of drag. Jaguar’s designers ensured the additions integrate seamlessly, preserving the sedan’s grand touring poise without compromising its aggressive stance.

Chassis and Suspension Tuning

Beyond powertrain and aero mods, the Speed Pack includes revised suspension settings. Though specifics remain proprietary, these adjustments sharpen handling, reduce body roll, and improve cornering precision at elevated speeds. The result is a more composed ride that instills confidence whether carving canyon roads or cruising motorways.

• Key Chassis Benefits: Enhanced damping for better control.
• Optimized spring rates to minimize dive and squat.
• Retuned steering for sharper response.

This holistic approach ensures the XFR Speed Pack isn’t just faster in a straight line but more capable overall.

Pricing and Availability Details

In the UK market, the Speed Pack added £2,750 to the standard XFR’s £65,380 starting price, making the equipped model available from £68,130. Across the Atlantic, it commanded a $3,900 premium over the $84,075 base 2013 XFR. These figures positioned it as an accessible upgrade for buyers already invested in Jaguar’s flagship saloon.

Debuting at events like the Moscow Auto Show, the pack quickly became a sought-after option for those prioritizing velocity.

Performance Benchmarks and Rivals

The standard XFR impressed with its 0-60 mph in around 4.7 seconds, but the Speed Pack’s tweaks shaved fractions off high-speed acceleration. Topping out at 174 mph, it rivaled German counterparts like the BMW M5 and Mercedes E63 AMG, offering British flair at competitive velocities.

Fuel economy benefits from the 8-speed gearbox and stop/start, with real-world figures hovering around 20-25 mpg combined, a notable feat for a 510-hp supercharger setup.

Interior and Everyday Usability

Inside, the XFR Speed Pack retains Jaguar’s opulent cabin. Leather-wrapped surfaces, aluminum accents, and a driver-focused cockpit provide luxury without distraction. The 8-speed auto shifts seamlessly, making it ideal for daily commutes or long hauls. Rear space accommodates adults comfortably, underscoring its grand tourer credentials.

Legacy in Jaguar’s Performance Lineup

Launched amid the XF range’s updates—including a new 2.2-liter diesel entry and 3.0-liter supercharged V6—the XFR Speed Pack capped the hierarchy. It exemplified Jaguar’s 2010s push to blend heritage craftsmanship with modern supercar pace, influencing successors like the F-Type and reimagined XF.

Though production ceased years ago, used examples remain desirable for their rarity and capability. Values hold steady among collectors valuing understated British muscle.

Driving Impressions and Owner Feedback

Owners praise the pack’s transformation: the extended top speed unlocks a new dimension, while aero aids make it feel glued to the road. The supercharger’s whine adds theater, and torque delivery feels effortless from low revs. Drawbacks? Thirsty at full tilt, but that’s the price of unfiltered performance.

Maintenance Considerations for Speed Pack Owners

Supercharged V8s demand premium care: regular oil changes, belt inspections, and cooling system checks are crucial. The ZF transmission benefits from fluid flushes every 60,000 miles. Aero components withstand elements well but warrant cleaning to prevent lift degradation.

• Annual supercharger pulley checks.
• Suspension bushings every 50,000 miles.
• Tire upgrades to high-speed rated rubber.
