Diesel power plants will continue to be the majority means of propulsion for Jaguar Land Rover products in the future, said the company’s UK managing director Jeremy Hicks in conversation with Autocar.

Diesel models account for 70% of the automaker’s UK sales, equating to approximately 70,000 vehicles a year. Its diesel sales success can be attributed to a successful push for fleet buyers, whose purchasing decisions are weighed heavily by CO2 emissions figures. Fleet sales has grown from 37% in 2013 to 44% in 2015, and is expecting it to grow further towards the industry average of 46%.

“I am not convinced that we’ll see a wholesale change away from diesel. And we are certainly not seeing any marked shift away from diesel today,” said Hicks.

The company has already made its commitment towards oil-burners – its first engine from the new Ingenium range of powertrains is a 2.0 litre turbodiesel, which has been on sale on the Jaguar XE and XF and the Land Rover Discovery Sport and facelifted Range Rover Evoque since last year. Petrol variants, including a rumoured straight-six, are only set to go into production later this year.

In contrast, Volvo could reportedly drop diesel power plants from its future lineup due to ever-tightening emissions requirements. The Swedish carmaker’s upcoming 40 Series range of models are designed from the outset to embrace conventional, full-electric and plug-in hybrid powertrains, further growing its independence from diesel.

For its larger 90 Series models such as the XC90, S90 and V90, the marque’s Scalable Product Architecture (SPA) gives rise to the T8 plug-in powertrain, which in the seven-seater XC90 can achieve a consumption figure of 2.1 litres per 100km under the European NEDC test cycle.

Europe, a traditional diesel stronghold, is predicted to see a continued drop in diesel market share to 37% by 2027, which adds to the significance of alternative powertrain options such as plug-in hybrids and EVs.
