News : JLR racks up 1.5 million Ingenium engines

Ingenium D6 engines in production

Jaguar Land Rover has marked the production of more than 1.5 million Ingenium engines. The family of engines, introduced in 2015 to power the model range in the wake of the Ford’s sale to Tata, is now used across the entire range following the introduction of the new 3.0-litre straight-six mild hybrid diesel. 

The Engine Manufacturing Centre in Wolverhampton was created to build the Ingenium engine. It was a big part of JLR’s expansion plan for the 2010s, based on the introduction of a much larger model range, including a range of Jaguar SUVs, and an expanded Range Rover line-up. With the introduction of the Land Rover Defender, Range Rover Velar and Jaguar E- and F-Pace, that process is now complete.

The all-aluminium Ingenium family, which includes a range of diesel, petrol and electrified engines, are built to maximise performance and efficiency, and were developed to be modular, flexible and scalable, with common core technologies.

The latest addition to the Ingenium range is the six-cylinder mild hybrid diesel engine, which powers the 2021 Range Rover and Range Rover Sport. The new variation joins the range of four and six-cylinder petrol and diesel engines made in Wolverhampton.

The evolving Ingenium family supports the company’s long-term commitment to reduce vehicle emissions and improve fuel economy across its vehicle range. This is part of its Destination Zero mission and a commitment to reducing emissions and making environments cleaner through relentless innovation.

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.

  1. At last a British motor industry success story! The creating of a base engine capable of being modified for several different purposes reminds me of GWR CME George Jackson Churchward. He took over in 1902 as CME and used as the base for various classes of passenger tender locomotives a standard 4-6-0 wheel arrangement, Belpaire firebox and taper boiler. Some of his design could be seen in British steam locomotives up and including the 1950s BR Standard Class engines.

  2. I wonder how many of those 1.5 million are to replace failed 2L diesel engines in Discovery Sport / Evoques? They are not enjoying a great reputation for durability or reliability with oil dilution and camshaft bearing surface wear. Would like to upgrade my Sd4 Freelander 2 but dubious about doing so to something with this engine. I know you can hear horror stories about any make and its only the bad reviews that make the headlines with countless thousands of happy customers but I’d hate to get my fingers burnt with one of these.

    • You forgot to mention balancer shaft bearing failure. These engines live up to their illustrious ancestry – from Stag V8 and Dolomite Sprint overheating/timing chain stretch to K Series HGF – Why did we ever imagine the British Motor industry could come up with a power unit that worked and didnt result in mind-blowing stress and inconvenience to its owners?

      • Er, let’s see now : Jaguar XK ( about 44 years ); BMC B series 1947-1981 ; BMC A series 1951 – 2000 – or were those just figments of the imagination, Paul, and then there were others such as Ford E93A/100E, Royce V8 1959-2020 and counting ……

        • Spot-on Christopher. We have a perverse sense of patriotism by slagging off our past selectively.

        • Sorry, but I beg to differ on this one. In Australia the XK had a terrible reputation for longevity. There was a cottage industry putting chev V8s in XJ6s. A series was ok in Minis but B series was rough as guts even if in an MGB it was part of the charm. And then there was the infamous Stag V8. The license produced KV6 in the Kia Carnival had literally the worst warranty record of any engine ever sold Down Under.

          Only the Buick/Rover V8 and Mr Bloor’s Triumphs really cut the mustard

          • I think you will find that if we look at engines across the board we can find issues with all nation’s engine designs. The Ingeneum 4 cylinder had a bad start but it’s reputation has improved greatly, it is the six cylinder that is really letting the side down.

            Th XK was a good engine other than it over heated easily in hot climates which is why he probably had a bad reputation down under. Also in the 70s, as with all BL products, the XK engine was not that well put together. The B series was a rough old unit, but no worse than other designs that started life in the 50s – it just lived to long so people remember how rough it was later on in life. The Stag V8 has been proven to be an excellent car engine after the 70s, with specialists proving that with the right development and maintenance it is an eminently capable engine. The Chinese did the same with the K series – though powertrain supposedly developed this before Rover went bust. The issue here is not British design – it is British management. They wanted products to the table too quick, and when problems were discovered they sat on their hands. Ford and Leyland down under were known for this. If the British, Germans and Japanese ever got together we would have some of the best products in the world.

  3. Statistics like this are something to be proud of in the UK Car industry at the present time. Let’s hope JLR continue to flourish in the tricky times ahead – along with other UK based manufacturers. My brother’s XF has an Ingenium engine and he tells me the MPG is excellent.

  4. My brother also a Jag, an xe 2.0 d which racks up 70mpg on his daily commute, its very impressive. When he bought the car from a Jag specialist the dealer said the 4 cylinders were brilliant engines after the initial teething problems but said the 6 cylinder was a complete nightmare.

  5. Ingenium engines from Wolverhampton power the new Defender of course. So even though it’s built in Slovakia which has irked some, an important and high-value chunk of the vehicle is very much “manufactured in the UK”.

  6. Great news, despite the usual people referencing past engine issues. 1.5m is very impressive for a completely new engine, factory etc.. I had one in my XF and it was great and the car was much more reliable than my previous MB C300.

  7. re Daveh, above – is there a reliability difference between the 6 and 4 cyl Ingenium? if so why would that be? It’s an identical cylinder – or is it the turbocharging? Great to see they’ve got the 4 sorted.

  8. Surprised the 6 cylinder versions are causing problems, as they’ve been in production for such a short period of time?

  9. Would like to read some actual evidence about the 6 cylinder engines rather than unsubstantiated comments.

  10. 1.5M units made in the West Midlands rather than China. That’s great: I had no idea volumes were so high.

    • It’s used in a lot of vehicles, and the likes of the Evoque and Disco Sport are big sellers for JLR

  11. Ingenium in my previous XE (15-plate, one of the first) was fantastic. Easily >60mpg on a long run. I think it’s transverse applications where they seem to struggle, but no experience of that personally. My neighbour’s Disco Sport needed a new engine but that had the old 2.2.

  12. Unfortunate JLR lost £1 billion in the first 6 months of 2020, they have broken off talks with the Govt for funds and the poor credit record of JLR stops Bank of England help with money. It is now down to private sources an injection of money for JLR

  13. Why did they not put the ingenium in the I-Pace and offer it at a realistice price? (Shame the I-Pace is sooh wide).
