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.

BMW, Mercedes ponder challengers to Uber

With autonomous vehicles seemingly just on the horizon of actually arriving to consumers, companies in the auto industry are already thinking about how the innovations could radically change how they do business. For example, BMW and Mercedes-Benz are considering a time where they might transform into ridesharing companies, according to Reuters. It almost sounds like the sci-fi motoring world Bob Lutz is predicting. The German brands foresee a future where some people hail their driverless cars like taxis and use them for short trips. The automakers could run those fleets, essentially making them Uber competitors. In fact, Tesla is reportedly mulling the idea, and Google might be, too. Alternatively, ridesharing services could buy the companies' models directly. "New mobility concepts will emerge with autonomous vehicles, which are robot cars. Fleet management will become a much more significant business," Peter Schwarzenbauer, BMW board of management member in charge of Mini, said to Reuters. With BMW's DriveNow and Daimler's Car2Go car-sharing services, both automakers are already experimenting with alternative ways to get their vehicles on the road. It's not too hard to imagine one of the brand's peppering a few autonomous cars into those fleets someday to test these new theories in the real world. "The ability to use a car, and then walk away is a serious business," Ian Robertson, BMW's head of sales and marketing, said about the future of driverless tech to Reuters. Related Video:

'The best Lewis' Hamilton faces resurgent Ferrari in F1

SHANGHAI (Reuters) - Lewis Hamilton has raised his game but whether the Mercedes driver can deny Ferrari a second successive win of the season in China this weekend remains to be seen. On paper, the triple world champion is still the man to beat -- the most successful driver by far in Shanghai with four wins to date. "Lewis is the best Lewis that I've seen in the last four years, both on and off the track," said Mercedes team boss Toto Wolff after the Briton started on pole and finished second to Ferrari's Sebastian Vettel in the Australian season-opener. "He has become a pillar of this team and he proved that in Melbourne." But Vettel is leading the championship, the first time a non-Mercedes driver has done that since he took his fourth title with Red Bull in 2013, and once-dominant Mercedes have a fight on their hands. Mercedes, who have taken both the drivers and constructors' titles for the last three years, have won four of the last five races in China. As Melbourne showed, however, past form may count for little in a season of sweeping rule change. "If you think you are going to cruise to victory in the future, based on a track record of success, you'll be proven wrong very quickly," said Wolff. "Australia was a weekend full of lessons, now we go to China ready and excited for another battle." Ferrari have not started a season with consecutive wins since 2004 at the peak of the Michael Schumacher era, the Italian team taking 15 victories from 18 races that season. Vettel's win in Australia ended a victory drought for Ferrari stretching back to September 2015, and drew rare praise from company chairman Sergio Marchionne, but they must now prove they can be genuine contenders. "You really have to go step by step," said Vettel. "It's good to know that we have a great car but it's just the beginning: new regulations, new generations of cars so there will be a lot of progress." The cars this year are longer and wider, sporting fatter tires and more swept-back bodywork as part of a rules shake-up aimed at making them faster, more spectacular to watch and harder to drive. But overtaking has also become more difficult, with Australia raising concern about the lack of real moves. The long straights and wide sweeps of the Shanghai circuit saw 128 passes last year, more than at any other track, and should provide a more definitive verdict.
