Porsche has axed the diesel variant of its Macan SUV with immediate effect, blaming a lack of demand.

The firm said that diesel engines “traditionally plays a subordinate role” as the sports car manufacturer does not develop or build its own diesel engines, instead sourcing them from other parts of the Volkswagen Group stable of companies.

A statement from the brand added that interest in its petrol and hybrid models “is increasingly significantly”.

Porsche produces hybrid and plug-in hybrid variants of the Cayenne SUV and Panamera saloon.

The company also said the decision to drop the diesel from the Macan range relates to “ongoing consultations with the authorities in relation to another software update”.

That is likely to refer to the need to re-engineer the engine to comply with the tougher WLPT emissions testing regime that comes into force in September.

Its statement concluded: “Porsche has made changes to its production planning and has set the end-of-production date for the Macan S Diesel to 15 February 2018. This decision means that all orders for the vehicle type Macan S Diesel have already been taken out of the production program.”

A spokesman for the company told Company Car Today that no final decision has been made whether there will be diesel models in the future.

The company dropped the diesel version of the Panamera saloon earlier this year, with it no longer appearing as an option on the company’s UK website. It was powered by a 4.0-litre 422hp V8 engine that emitted 172g/km of CO2 and returned 42.2mpg.

Porsche first launched a diesel variant in 2009 when it launched the Cayenne SUV, however the new version, launched last year, did not include a diesel version.
