Ingenium Engine Family 2014 – Present

Ingenium Production Line

In September 2014, Jaguar Land Rover announced the Ingenium family, a range of modular engines produced in both petrol and diesel variants to power the new Jaguar XE and future models from Jaguar Land Rover.  Ingenium uses a modular architecture making it possible to be produced in 3, 4, 5, and 6 cylinder versions (built around individual 500 cc cylinders), and as hybrid variants, depending on demand and requirements.

From late 2015, Ingenium replaced the engines sourced from Ford’s engine plant in Bridgend in Wales.  The engine range is produced at the new £500 million, 100,000m2 Engine Manufacturing Centre at Wolverhampton in the West Midlands in the UK.

Ingenium’s design is configurable and flexible for longitudinal and lateral architectures and for front, rear, and all-wheel drive, together with auto and manual transmissions.    Depending on configuration, engines have either a single twin-scroll turbo-charger, or two twin-scroll turbo-chargers, with ceramic ball bearings.  Valve train design follows the traditional Jaguar approach of chain driven double overhead camshafts (DOHC).  Particular emphasis has been placed on achieving exceptionally low internal friction, which is described as being 17% less than its 2.2 litre diesel predecessor.   Computer-controlled variable oil and water pumps and a split circuit cooling system enable fast warm ups.  While a simplified cam drive system, crankshafts that are offset from the centre of the block, and electronically controlled piston cooling jets all help to improve efficiency in the oil pumping circuit.

Starting from a clean sheet, meant that Jaguar’s powertrain engineers could make the Ingenium engines as light and efficient as possible, and deliver the blend of power, torque and smoothness customers expect.  These state-of-the-art engines were proven over 2 million miles of real-world testing.

Ingenium Diesel Engines

Ingenium Diesel

The new generation of Ingenium diesel engines are wholly designed and manufactured by Jaguar Land Rover.  No opportunity has been missed in ensuring their design is right on the cutting edge of technical advancement, making them the most efficient Jaguar diesel engines ever built.

The engine blocks are cast from aluminium alloy, with steel liners, producing stiff cylinder blocks with twin balancer shafts to ensure inherently low levels of vibration.  Details such as the acoustic sump cover, decoupled injectors, and 0.5 mm ovality on the injection pump drive sprocket contribute to the Ingenium’s exceptional quietness.  The cam and balancer shafts have roller bearings instead of machined-in bearing surfaces, helping to produce a very low friction engine.

Ingenium Diesel Cutaway

The AJ200D 2.0-litre Ingenium diesel was initially offered in two power outputs.  The first, rated at 163 PS / 380 Nm, delivers benchmark efficiency figures of 75 mpg and 99 g/km CO2 without any compromise to launch performance or mid-range acceleration.  The 180 PS / 430 Nm variant has one of the highest torque outputs in the class.  Further versions have since been launched offering 150 PS / 380 Nm and 240 PS / 500 Nm.

Ingenium diesels met Euro 6 specifications making them as clean as they are efficient.  Variable exhaust valve timing shortens the catalyst light-off phase and also improves diesel particulate filter (DPF) regeneration.  The cooled low-pressure exhaust gas recirculation (EGR) system reduces combustion chamber temperatures, inhibiting NOx formation.  Selective catalytic reduction (SCR) technology, including the injection of AdBlue into the exhaust system, cuts NOx emissions to very low levels and the new XE has been engineered to meet the most stringent global regulations.

Ingenium Petrol Engines

Ingenium Petrol Cutaway

Petrol versions were launched in 2016, using the same architecture, initially in 2 versions based on direct injection 1,999 cc, four cylinder, turbo-charged configurations:  200 PS / 320 Nm and 250 PS / 365 Nm with a single turbo-charger.

In 2017 a twin turbo-charged 300 PS / 400 Nm engine with an electro-hydraulic valvetrain was launched.  Jaguar Land Rover licensed the MultiAir / UniAir electrohydraulic variable valve lift system from Schaeffler Group, which Schaeffler in turn licensed from Fiat Chrysler Automobiles in 2001.  The system, developed by Fiat Powertrain Technologies, is a hydraulically-actuated variable valve timing (VVT) technology enabling “cylinder by cylinder, stroke by stroke” control of intake air directly via a gasoline engine’s inlet valves.

The new four-cylinder engine, badged P300, benefits from the latest Jaguar Land Rover engine technology, including twin-scroll turbos with ceramic ball bearings to reduce friction and a high flow compressor wheel for enhanced performance.

Producing 400 Nm of torque it gives exceptional acceleration, enough to power the, World Car of the Year-winning, F-PACE from 0-100 km/h in 6.0 seconds (0-60 mph in 5.7 seconds) but still return fuel economy of 37 mpg (7.7 l/100 km).

In the Jaguar XF saloon the P300 engine delivers 0-100 km/h in 5.8 seconds (0-60 mph in 5.5 seconds) in all-wheel-drive form.  With CO2 emissions of 163 g/km and fuel economy of 40 mpg (7.2 l/ 100 km), it delivers traditional Jaguar performance allied to impressive efficiency.

For the XE saloon, the P300 engine delivers even more impressive figures.  The 0-100 km/h sprint takes only 5.5 seconds (0-60 mph in 5.2 seconds) for the all-wheel-drive model, while fuel economy of 41.5 mpg (6.9 l/100km) and CO2 emissions of 157 g/km ensure its strong eco credentials remain intact.

Ingenium Six Cylinder 3 Litre Petrol Engine Launched in February 2019

On Wednesday 13 February 2019, Jaguar Land Rover announced the launch of the new six-cylinder petrol version of the Ingenium engine, designed and engineered in-house, and manufactured at its £1 billion Engine Manufacturing Centre (EMC) in Wolverhampton, UK.

The 3.0-litre straight six cylinder petrol engine, which debuted on the Range Rover Sport, is available in 360 PS and 400 PS versions with a torque capable of up to 495 and 550 Nm, is more responsive and better balanced than the outgoing V6 petrol.

It features a unique combination of an electric supercharger to deliver immediate response supported by a twin scroll turbo-charger and Continuous Variable Valve Lift, which boosts power and helps the engine to breathe with maximum efficiency.

These performance-boosting technologies, combined with Mild Hybrid Electric Vehicle (MHEV) technology, optimises performance, fuel economy and reduces emissions.  The MHEV 48V system uses a small integrated electric motor to harvest energy lost during deceleration, and then intelligently redeploys it to assist the engine to maximise efficiency.

As of 15 February 2019 it has not yet been announced which Jaguar models the new engine will power, but we look forward to it and will update this web page as soon as we have any news.

On 17 July 2020, Jaguar Land Rover announced that it has built 1.5 million Ingenium engines at its Engine Manufacturing Centre at Wolverhampton.  The Engine Manufacturing Centre also houses the assembly of Electric Drive Units (EDUs), offering full flexibility between new petrol and diesel engines and EDUs for those customers who want to make the switch from conventional to electrified vehicles.

The Wolverhampton site is complemented by a growing electrification ecosystem in the Midlands, with the innovative and technologically advanced Battery Assembly Centre at nearby Hams Hall assembling PHEV and BEV batteries. Together, they will power the next generation of Jaguar and Land Rover electrified vehicles.

Ken Close, Jaguar Land Rover Powertrain Operations Launch Director, said: “We are experiencing unprecedented demand for cleaner-running vehicles, so it’s more important than ever to deliver clean and efficient engines without compromising on the performance or all-terrain capabilities our customers have come to expect.  Our Ingenium powertrains offer the very best of both worlds – better fuel efficiency and lower emissions, and even greater torque for a more responsive and engaging drive.”
