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.

McLaren Racing will return to Mercedes F1 engines from 2021

SOCHI, Russia — McLaren will be reunited with Mercedes engines from the 2021 season as the former champions go back to using the German manufacturer's power units in their bid to return to the top. The Woking-based team are currently supplied by Renault, having joined forces with the French company last year. They will see out that deal, which runs until the end of 2020, before making the switch back to Mercedes as part of a long-term agreement until at least 2024. "We are delighted to welcome McLaren back to the Mercedes-Benz racing family with this new power unit supply agreement," said Mercedes' motorsports head Toto Wolff in a joint statement with McLaren issued at the Russian Grand Prix on Saturday. "We hope that this new long-term agreement marks another milestone for McLaren as they aim to take the fight to the sport's top teams, including our Mercedes works team." The McLaren-Mercedes partnership initially ran from 1995 to the end of 2014. It turned McLaren, enduring a slump after their heady days of dominance during the late 1980s and early 90s with Honda, into a force to be reckoned with once again. The combination won 78 races, a constructors' title and three drivers' titles with Mika Hakkinen (1998, 1999) and Lewis Hamilton who raced to his first Formula One title with the team in 2008. McLaren find themselves in a similar phase now, rebuilding after three dismal years with Honda, the Japanese manufacturer they rejoined forces with at the end of 2014 in a bid to recreate their dominance from 30 years ago. Fielding a fresh driver line up of British rookie Lando Norris and Spaniard Carlos Sainz, they have made big strides this year and are currently locked in a battle for fourth in the overall standings with Renault's works team. But they haven't won a race since the season-ending 2012 Brazilian Grand Prix, when they were still powered by Mercedes. "Renault has been instrumental to our Formula One recovery plan and a fantastic partner to McLaren Racing," said Zak Brown, chief executive of McLaren Racing. "This agreement is an important step in our long-term plan to return to success in Formula One." McLaren's new deal with the German manufacturer, whose power units have set the benchmark in Formula One's turbo-hybrid era, coincides with a planned rules overhaul aimed at leveling the playing field and creating better racing. The shake-up could be just what a team like McLaren need to make that final jump up to the top.

2014 Mercedes-Benz E63 AMG S 4Matic [w/video]

Maybe you saw our recent blog snippet on a bunch of US journos getting pulled over in the middle of nowhere in Catalunya, Spain for driving a bunch of new 2014 Mercedes-Benz E63 AMG models. By all accounts, they weren't speeding - which makes me softly guffaw. I was there in that group, yet I had taken the more direct route into the mountains from Barcelona so that I could... well, so that I could go faster. No one hassled me and I had the Autovia all to myself. And it was the goodniks - the team players - who got nabbed because Spain had decided to suddenly enforce the never enforced "must carry an international driver's license" clause of the highway code.
The departing E63 AMG with 518 horsepower and 516 pound-feet of torque from its M157 5.5-liter biturbo V8 hasn't exactly been poorly received. It isn't as crisp as, nor as pleasantly evil as its C63 AMG kid brother, but we generally accept that the heavier and larger car will always feel, well, heavier and larger.
As part of the 2014 E-Class mid-cycle redesign, Affalterbach decided to give its E63 AMG more power and torque for the occasion. The base car now gives off 550 hp and 531 lb-ft, while the hotter S version I tested (formerly the AMG Performance Pack) produces 577 hp and 590 lb-ft. The other big novelty is that E63 sedans will be available with both rear- and all-wheel drive, while all US-spec E63 wagons will be 4Matic equipped.
