Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

Mercedes considering Audi Allroad rival

The Audi Allroad is something of an anomaly in the automotive world. Its competitors are limited to the recently released Volvo V60 Cross Country and perhaps the far cheaper Subaru Outback. The lifted premium wagon hasn't exactly done great for Audi, only selling a few hundred examples each month. Its best sales year was 2013, and even then, only 5,300 left US showrooms. Despite these limited prospects, word from Australia is that Mercedes-Benz is looking at launching its own competitor to the Allroad. "We are looking at every single niche, so we are studying this [Allroad] at the moment, but it is not confirmed," Matthias Luhrs, VP of sales and a member of the product management at MB, told Motoring.com.au. "We are looking obviously at C-Class and E-Class, but no confirmation at the moment." Fortunately, Luhrs recognizes that the Allroad isn't exactly a smash in the US. "In the US, no matter how long, short, high ... they don't like station wagons," Luhrs said, while adding that the Allroad concept is "developing quite successfully" in Italy and southern Europe. And for those hoping for a lifted C- or E-Class sedan, Luhrs also put the kibosh on that, saying, "We are not studying that." So what does this tell us? Well, it's still far from a sure thing that Mercedes will launch a lifted C-Class or E-Class Estate. And even if the company does go ahead with it, like the rest of the brand's long roofs (E-Class aside), don't expect to see it on US roads.

Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.
