Land Rover Discovery Sport IngeniumLand Rover has replaced the SD4 engine in the Discovery Sport with all-new Ingenium TD4 engines – just a year after launch.

The arrival of the Wolverhampton-built 2.0-litre TD4 Ingenium engine range sees fuel economy improve dramatically, with a similarly striking reduction in CO2 emissions.

Offered in both 150hp and 180hp guise, the TD4 Ingenium engine replaces the current 2.2-litre SD4 190 motor; in base TD4 150 guise, it averages 57.7mpg and emits 129g/km CO2 – a massive 25% rise over the 46.3mpg and 162g/km CO2 of the current SD4 190.

These TD4 150 models will carry blue ‘Sport’ badges on the rear, denoting E-Capability status.

The 180hp version is almost as impressive, averaging 53.3mpg and emitting 139g/km CO2.

Land Rover also offers a nine-speed automatic version of the TD4 180 motor: this ups fuel economy and emissions from 44.8mpg and 166g/km CO2 for the current SD4 190, to the same 53.3mpg and 139g/km of its manual sibling.

Price unchanged – AND lowered

Murray Dietsch, Director of Land Rover Programmes, said: “Land Rover’s new family of Ingenium engines is truly class leading. By introducing it to the Discovery Sport, we can now offer enhanced fuel economy and reduced CO2 emissions, while improving overall performance.”

The new TD4 180 engine is price-matched to the current SD4 190 motor, so prices will start at £32,395.

The TD4 150 engine is a new lower-power addition to the range and comes with a lower entry price of £30,695. This model will only have five seats though, instead of the 5+2 of all other Discovery Sport.

Ingenium engines will replace the aged SD4 motor in all Euro 6 markets from September 2015 – exactly a year after the 2014 Paris Motor Show launch of the Discovery Sport.
