Last year, Volvo CEO Håkan Samuelsson said the company would stop developing new diesel engines and it now appears the automaker will begin eliminating them from their lineup.

In an interview with the Financial Times, Samuelsson revealed the 2019 S60 won’t be offered with a diesel engine. The car will be unveiled in South Carolina this summer and built at the company’s new Ridgeville factory which is located in the state.

The decision not to offer the S60 with a diesel engine is a big change but it builds on the announcement that all future Volvo models will be electrified. The company has also stated it wants 50% of their sales to come from electric vehicles by 2025.

According to Samuelsson, the decision to ditch diesel isn’t necessarily about emissions as he noted “We’re not saying diesel is more dirty, but it’s more complicated and more expensive.” He went on to say new emissions standards will make it tougher for automakers to build diesel engine that are compliant with the new rules. This, in turn, will drive up costs as well as complexity.

Samuelsson wasn’t completely dismissive of diesel engines as he noted their only advantage is lower fuel consumption figures than traditional gasoline engines. However, he said mild-hybrid technology can make petrol engines much more efficient.

Volvo will continue to offer diesel-powered models but the lack of a diesel engine in the S60 is a sign of things to come. Eventually, the automaker will drop diesel engines altogether but there’s no word on a timeframe.

Since we now know the S60 won’t be offered with a diesel engine, it appears only petrol engines from the V60 will carryover. As a result, we can expect a 2.0-liter T6 producing 310 PS (228 kW) and 400 Nm (295 lb-ft) of torque. There could also be an entry-level T5 as well as two plug-in hybrid variants with outputs of 340 PS (251 kW) and 390 PS (288 kW).
