Porsche has become the latest car giant to contemplate fuelling diesel's decline, with boss Oliver Blume saying the company could discontinue diesel.
In an interview today with Reuters, chief executive Blume said Porsche will decide at the end of the decade whether its latest generation of diesel engines will be its last.
“Of course we are looking into this issue,” Blume said. “We have not made a decision on it.”
The Porsche boss said his company will offer a mix of combustion engines, plug-in hybrid vehicles and purely battery-powered cars over the next 10-15 years, and will decide at the end of the decade whether to continue with diesel at Porsche.
Diesels still account for around 15 per cent of Porsche's global sales, but the car firm is spending a billion euros (£888m) rejigging its main Stuttgart plant and building its first battery-only model, due on the market in 2019.
Blume said battery-only vehicles could account for a quarter of Porsche's sales by 2025.
The Swedish firm said all cars from 2019 will have an electric motor, which it said was “heralding the end of an era for the pure internal combustion engine”.
From 2019, it will offer a range of electrified cars, spanning plug-in hybrid cars, mild-hybrid cars which have a small petrol engine and a large battery, and pure electric models. Volvo will gradually phase out internal combustion cars.
Car firms have been increasing their efforts to take on the electric car market and last month, the number of electric vehicles on the road topped the 2m mark globally.
Prices have fallen and manufacturers have been launching a raft of new models in an effort to woo hesitant consumers still suffering from range anxiety. And there has been an impact, with sales rising 60 per cent last year, though electric vehicles still represent just 0.2 per cent of total light-duty vehicles.
