Mercedes-Benz takes the electric car plunge, but diesel is here to stay

Daimler AG executives said Tuesday that diesel power for Mercedes cars is here to stay, even as electric cars and electrified mobility spreads throughout its passenger and commercial vehicles, and even its global partnerships.

Electrified vehicles include everything from 48-volt mild hybrids through plug-in hybrids to battery-electric cars.

At the Geneva Motor Show, Daimler chairman Dieter Zetsche said Tuesday his company would not change its diesel strategy, despite a German court ruling that said cities could legally ban older diesels in an effort to reduce dangerous levels of nitrogen oxides that contribute to air pollution.

Zetsche added that the company sold more diesels around the world in 2017 than it had in 2016.

The issue of nitrogen-oxide emissions has been debated and largely solved, said Ola Källenius, head of Daimler research and product development.

The company’s new generation of diesels use urea injection to mitigate those emissions, and make their exhaust gases almost indistinguishable from those of gasoline engines on that front.

However, older diesels—the majority of such vehicles on the road—do not have those systems. New rules that mandate tougher diesel emissions in Europe came into effect only at the start of 2017, almost a decade after emissions limits in the U.S. mandated the systems.

Källenius says the diesels his company now sells, and those currently under development, emit 15 to 20 percent less carbon dioxide than their gasoline counterparts.

That’s why—at least for the European market—Daimler still sees a strong future for diesels.

“If we stay rational, (it’s still a) very good choice for many customers, especially if you do a lot of miles,” he said.

Electrics slide into place with EQ family

Customers around the world have distinct needs, and Källenius added that it would be “unwise” for Mercedes-Benz to rule out diesel altogether as a choice.

But while diesel has a role in Daimler’s lineup, executives said emphatically that all future Daimler vehicles would be electrified.

“We definitely have switched to a full-fledged commitment to electromobility,” Zetsche said.

In passenger cars, Daimler will gradually introduce 48-volt technology across the four platforms and 40-plus nameplates it sells worldwide.

That technology will enable it to electrify all its vehicles to some extent: it will be able to sell diesel, mild-hybrid, and plug-in hybrid vehicles that all use the same 48-volt platform.

A wave of plug-in hybrid vehicles will emerge under a new EQ sub-brand across the Mercedes and Smart lineup.

Starting with the new compact family of cars that arrive this fall, Mercedes will sell plug-in hybrids with 30 miles of electric driving range or more, with longer-range versions still in development.

The EQ brand will be further split into EQ Boost, the 48-volt mild-hybrid system; EQ Power, which will be applied to plug-in hybrids; EQ Power Plus, for AMG-branded models; and EQ, for pure battery-electric vehicles such as the compact crossover vehicle Mercedes will unveil this fall.

In the medium term, Mercedes plans to sell a plug-in hybrid in every vehicle lineup, before it begins to sell a wide range of battery-electric cars.
