Daimler and Geely collaborate to develop 'a highly efficient modular engine'

BERLIN — German car maker Daimler said on Tuesday it will cooperate with China's Geely to build next-generation combustion engines for use in hybrid vehicles. Efforts to share development costs come as the growth potential for combustion engines faces the twin threat of the COVID-19 crisis and stricter fuel-efficiency and emission rules. "The companies plan to develop a highly efficient modular engine," a spokesman for Daimler said, adding that it would be used in hybrid drivetrains and manufactured in Europe and China. Geely declined to comment. The modular engine will be used in cars under different marques at Geely and Daimler, a person familiar with the matter said on condition of anonymity as the companies are still in the early stages of developing the engine. News of the alliance was a surprise to Daimler's works council at its factory in Untertuerkheim, which specializes in electric and gasoline powertrain assembly. "We are speechless. There was not even a discussion about potential alternative manufacturing locations," said Michael Haeberle, the works council chief for Untertuerkheim. "We have the ability to build four-cylinder engines in Untertuerkheim, but there were no talks about it." Daimler said German factories will be retooled gradually to add electric drivetrains production. Most of the next-generation combustion engines will be made in China, business daily Handelsblatt reported. The alliance with Geely, which owns a 9.69% stake in Stuttgart-based Daimler, means that parts of Daimler's existing partnership with Renault could be pared back. A Renault source told Reuters that the Daimler-Geely project does not mean an end of cooperation between Daimler and Renault. Citing Daimler sources, Handelsblatt said the Daimler-Geely pact would save the German carmaker a "triple-digit million sum" — implying an amount above 100 million euros ($119 million) and less than 1 billion euros.

2017 Mercedes SL leaks online ahead of LA debut

Mercedes-Benz already teased the refreshed face for the SL-Class with a shadowy photo ahead of a big debut at the Los Angeles Auto Show, but a newly leaked gallery now sheds light on the upgraded luxury convertible. The 32 photos provide a look at several models of the droptop, and you can check them all out in the gallery above. As the teaser suggests, the new front end adapts elements from the AMG GT like narrower, arched headlights that include the LED running lights. Mercedes' designers also resculpt the hood and fit a front bumper with an additional opening between the grille and lower air dam. The rear incorporates tweaked taillights and a bumper that features small vents just behind the wheels. There appears to be some updated trim inside like a different steering wheel and infotainment improvements. While these images provide a complete look at the updated design, the technical details about the refreshed SL-Class are still a mystery. According to Germany's Auto Motor und Sport, some models reportedly receive a nine-speed automatic, the Dynamic Select system to tweak the drive, and Active Body Control to lean into corners. Upgraded brakes are also allegedly on the AMG models. All of these improvements seem plausible, and we might see some engine adjustments too. We get to learn about any more changes very soon at next week's LA Auto Show.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
