The 2017 model year marked a significant expansion for the Jaguar XF lineup, most notably with the introduction of an all-new diesel powertrain. This addition not only broadened the dynamic capabilities of the popular mid-size sport sedan but also enhanced its fuel economy, catering to a wider range of drivers in the US market. For the first time, American customers could experience the refined power and efficiency of a diesel engine in the Jaguar XF.
This groundbreaking diesel engine, christened the “Ingenium,” was designed and built entirely in-house by Jaguar Land Rover. It leveraged the brand’s expertise in lightweight aluminum construction and represented the vanguard of a new generation of engines for the US market. Dubbed the “20d,” this four-cylinder 180hp Ingenium diesel engine delivered a remarkable 44 percent improvement in fuel economy compared to the 3.0L gas V6, all while maintaining comparable torque.
The integration of the diesel engine expanded the 2017 Xf model range to an impressive 18 variants. Customers could choose from three distinct engine options: the 340hp “35t” gasoline V6, the more powerful 380hp gasoline V6 “S”, and the fuel-efficient 180hp four-cylinder “20d” diesel. These engine choices were further customizable across five trim levels: the base XF, XF Premium, XF Prestige, XF R-Sport, and the top-tier XF S.
The Ingenium Engine: A New Era of Power and Efficiency
The 2017 XF’s Ingenium engine was more than just a new option; it was a statement of Jaguar Land Rover’s engineering prowess. This 4-cylinder engine was the first in a family of both diesel and gasoline Ingenium engines, meticulously designed, engineered, and manufactured in-house. Starting with a clean slate allowed Jaguar’s powertrain engineers to prioritize lightness and efficiency, crafting engines that delivered the power, torque, and smoothness expected from a Jaguar. Before reaching consumers, these engines underwent rigorous testing, accumulating over two million miles in real-world conditions.
Engine Construction and Performance
The Ingenium diesel engine is built around a deep-skirt aluminum cylinder block, incorporating thin-wall, press-fit cast iron liners. This design optimizes the balance between weight, surface finish, and durability. A key characteristic of the Ingenium diesel is its rapid torque delivery at low engine speeds. The XF 20d boasts a maximum torque of 318-lb.-ft., sustained across a broad rev range, ensuring immediate responsiveness and robust acceleration whenever needed.

Weighing a mere 304 lbs (138kg), this all-aluminum engine incorporates twin counter-rotating balancer shafts. These shafts effectively neutralize second-order forces, achieving the smoothness and power delivery akin to a naturally aspirated six-cylinder engine, but in a more compact and efficient package.
A notable innovation is the integration of the sheet metal turbine housing into the air-gap insulated exhaust manifold. This not only reduces weight but also lowers the assembly’s thermal mass, enabling the catalyst to reach its optimal operating temperature faster, thus minimizing emissions. The low-inertia turbine wheel further enhances responsiveness.
Advanced Emissions Technology
The Ingenium engine was designed from its inception to comply fully with stringent US federal and state emissions regulations, including LEV 3 and CARB standards. To achieve this, it employs several key technologies, making it as environmentally clean as it is fuel-efficient.
A cooled low-pressure exhaust gas recirculation (EGR) system plays a crucial role in reducing nitrogen oxides (NOx). This system recirculates exhaust gases at low pressure – after the diesel particulate filter (DPF) – back to the turbocharger inlet for secondary combustion, lowering combustion chamber temperatures and inhibiting NOx formation. This low-pressure EGR system not only reduces NOx emissions but also improves fuel economy and transient performance across a wider RPM range, contributing to the powertrain’s responsiveness and drivability.
Complementing the low-pressure EGR is a Selective Catalytic Reduction (SCR) system. This system injects Diesel Exhaust Fluid (DEF) into the exhaust stream, where it mixes and passes through the SCR catalyst, converting NOx into harmless nitrogen gas. SCR technology is highly effective, reducing NOx emissions by up to 90 percent.
Mirroring Jaguar’s gasoline engines, the Ingenium diesel utilizes Variable Valve Timing, enabled by a cam phaser on the exhaust side. This accelerates catalyst heating, further reducing emissions during engine warm-up.
Additional features contributing to efficiency and reduced emissions include a split-cooling system, a mapped thermostat, and a fully variable mechanical water pump. These components work in concert to expedite engine warm-up, minimize friction, and reduce fuel consumption. An electronically controlled oil pump adjusts flow rate based on engine speed, load, and temperature, while switchable piston cooling jets operate only when needed, further minimizing parasitic losses.
All-Wheel Drive and Dynamic Driving Experience
The 2017 Jaguar XF diesel models offered the option of Jaguar’s torque-on-demand all-wheel drive (AWD) system, already proven in the 340- and 380-hp 3.0-liter supercharged V6 gasoline XF models. In normal driving conditions, the system directs all engine torque to the rear axle, preserving the classic rear-wheel-drive dynamics and agility that Jaguar is known for. Compared to permanent AWD systems, this approach maintains uncorrupted steering feel and reduces driveline parasitic losses.

The Intelligent Driveline Dynamics (IDD) system governs torque transfer to the front axle. This sophisticated technology, developed in-house by Jaguar Land Rover, continuously assesses tire-road surface friction and grip utilization at each tire. IDD integrates predictive, feed-forward control strategies with reactive, feedback control and is networked with the Dynamic Stability Control (DSC), Torque Vectoring, and Jaguar Drive Control systems.
When IDD anticipates rear axle traction limits, torque is seamlessly transferred to the front axle. Torque can also be proactively distributed to the front to mitigate oversteer during spirited cornering, enhancing yaw damping.
AWD-equipped diesel models achieve 0-60mph acceleration in as little as 7.9 seconds, with an electronically limited top speed of 121mph. The 180hp Ingenium diesel delivers a robust 318-lb.-ft. of torque from just 1,750rpm, providing strong mid-range acceleration and exceptional real-world performance for everyday driving.
Configurable Dynamics, previously available on V6 models, was extended to the 180hp four-cylinder diesel Prestige and R-Sport models. This feature allows drivers to personalize settings for suspension, steering, throttle, and transmission via the vehicle’s touchscreen. Vehicles equipped with the Jaguar InControl® Touch Pro™ infotainment system further benefit from Dynamic-i, which displays performance data like stopwatch, g-meter, lap timer, and graphs of pedal activation on the 10.2-inch touchscreen.
XF S AWD models also included Adaptive Surface Response (AdSR) as standard. Replacing the Rain, Ice, Snow mode in Jaguar Drive Control, AdSR optimizes throttle mapping, automatic transmission, and DSC system settings to suit various road surfaces. Derived from Land Rover’s Terrain Response® technology, AdSR maximizes available traction, boosting driver confidence in challenging conditions like icy roads. The combination of AWD and Jaguar All-Surface Progress Control system is unique in its class, ensuring the 2017 Jaguar XF delivers exceptional all-weather performance and capability.
Beyond its dynamic prowess, the Jaguar XF also excelled in practicality, offering a generous 19.1-cu.ft. (540-liter) luggage compartment.
