Cleaner Ingenium diesel engines for Land Rover Discovery Sport

Published: 27 April 2015

► New Ingenium diesel engine for Disco Sport
► Replaces the old 2.2 diesel across Europe
► Available in two power outputs, CO2 from 129g/km

We’ve been impressed with the Land Rover Discovery Sport thus far. Editor-at-large Mark Walton traversed an Icelandic glacier and returned singing its praises; back in Blighty we pitted it against its key rivals and it conquered them too, even outshining its glitzier Range Rover Evoque sibling. (Although some of our testers reckon Audi’s Q5 to be a marginally sharper drive).

Thing is, its sole engine offering was an aging Euro 5-spec 2.2-litre PSA-Ford-Jaguar-Land Rover turbodiesel.

That’s about to change, as that stop-gap engine is being substituted for Jaguar Land Rover’s shiny new Ingenium diesel family. The fresh Euro 6 emissions regulations-compliant Ingenium replaces the 2.2 in all of the Disco Sport’s European markets.

Land Rover Discover Sport Ingenium engines: vital statistics

JLR’s new Ingenium diesel family can also be found in the Jaguar XE and the new Jag XF, as well as the upcoming F-Pace Jaguar SUV. In the Discovery Sport, Land Rover’s calling the engine the ‘TD4.’

It’s being offered in two power outputs, 148bhp/ 280lb ft and 178bhp/317lb ft. The 148bhp is six-speed manual only, while the 178bhp gets a choice between manual or ‘my bike’s got less gears than that’ nine-speed auto.

If you want your Disco Sport with seven seats, you’ll need to upgrade to the 178bhp version. All models with that engine get the 5+2 layout as standard, while the 148bhp cars are five-seat affairs.

We’ve driven the 178bhp version in the Jaguar XE, and found it a bit grumbly at low speeds but hushed at a cruise, with an effortless swell of torque to whoosh it along the motorway. It's worth mentioning the old 2.2 unit was actually more powerful, with 187bhp, although the Ingenium does generate a smidge more torque.

Tell me the CO2 and mpg figures.

They’re pretty good. JLR’s hoping CO2 emissions starting from 129g/km will pique the interest of company car managers. Naturally, they belong to the manual 148bhp engine, which also manages combined fuel consumption of 57.7mpg.

Meanwhile, the extra seat-carrying 178bhp TD4 steps up to 139g/km CO2 and down to 53.3mpg. Land Rover claims identical figures for the manual and auto gearboxes.

Incidentally, the Ingenium engine will go a fair bit further between service intervals than the old 2.2 Euro 5 unit, with spanner work scheduled at 21,000 miles.

How much?

Deliveries start in September 2015, starting from £30,695 for the 148bhp manual in entry-level SE trim. That’s actually a bit lower than before.

Anything else new in Discovery Sport world?

There’s a new trim level, the HSE Black. Adding more kit and a heftier price tag to the previously range-topping HSE, it gets the ‘Black Pack’ as standard (dark exterior trim rather than chrome) and privacy glass – both options that plenty of customers have been choosing already, according to Land Rover. It doesn’t come cheap, though. You’ll need to shell out £41,250 to get into a Discovery Sport HSE Black auto.
