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.

Race Recap: 2015 US Grand Prix was wet, wild, and historic

Hurricane Patricia made landfall in Mexico this weekend, and made her presence known throughout the South. For two of the three days of the grand prix weekend it rained non-stop in Austin, so badly on Saturday that qualifying had to be postponed until Sunday morning, and then it only stayed dry enough to conduct the first two sessions. At the end of a tricky, slippery Q2 Nico Rosberg had put his Mercedes-AMG Petronas on the front row, one tenth ahead of teammate Lewis Hamilton. The German had done the best he could to keep his hair-thin chances of a World Championship fight alive. Daniel Ricciardo lined his Infiniti Red Bull Racing chassis in third ahead of teammate Daniil Kvyat, both drivers having moved up a place because Ferrari driver Sebastian Vettel took a ten-spot grid penalty for using a fifth engine and dropped to 13th. Continuing the two-up theme, Sergio Perez and Nico Hulkenberg were fifth and sixth for Force India. After that came variety: Felipe Massa in seventh for Williams, Max Verstappen for Toro Rosso in eighth, Fernando Alonso looking good in the rain for McLaren in ninth, and Romain Grosjean for Lotus in tenth. When the lights went out, Turn 1 set the tone. Pole position is on the outside line at Circuit of the Americas, and Hamilton had got himself far enough under Rosberg by the time the two got up the hill that Rosberg had to stick to the outside through the corner. At the corner exit Hamilton used the entire track, pushing Rosberg wide, their cars touching. As Rosberg left the track and dropped back to fourth, Hamilton radioed to the team to say the contact was unintentional. The two Mercedes' and two Red Bulls animated the front. Rosberg passed Ricciardo at the end of a Virtual Safety Car period employed to let the marshals clean the debris at Turn 1. Kvyat started chasing down Hamilton until the Russian ran wide and let Rosberg and Ricciardo through, then Rosberg ran wide on the next lap to let Ricciardo through. On Lap 15, Ricciardo passed Hamilton through the esses to take the lead. After the first round of pit stops the Aussie still had the lead, followed by Rosberg, Kvyat, Hamilton, and Vettel. Then Rosberg got around to take the lead and Vettel closed in on Hamilton as the Brit duked it out with the Russian. Rosberg showed excellent speed, building up a nine-second gap on Ricciardo, but a Safety Car period erased that when Marcus Ericsson had to park his dead Sauber on the inside of the track after Turn 10.

2014 Mercedes-Benz C63 AMG Edition 507 still lights our fire

The current Mercedes-Benz C63 AMG may be in the autumn of its years, but it's still one of our very favorite sport sedans. Ever. Yes, its paddle-shift transmission may not always follow orders, but with stupendous levels of thrust from its charismatic naturally aspirated 6.2-liter V8, ebullient rear-wheel-drive dynamics and that noise, we frankly don't care that it's getting on a bit.
As a sendoff of sorts for the current generation, Mercedes-Benz has just introduced a new Edition 507 model at the Geneva Motor Show, with 507 horsepower and 450 pound-feet of torque - an increase of 56 horses over the standard car. Mercedes credits the substitution of low-mass internals from the SLS AMG gullwing for the power bump, a tactic shared with the AMG Development Package upgrade that has been subsumed by this Edition 507. 0-60 is quoted at 4.1 seconds and top speed at 174 mph.
The Edition 507 borrows its aluminum hood from the C63 AMG Black Series Coupe, along with spidery new 19-inch wheels in either titanium gray finish or matte black with shiny rim flanges. As seen on our gallery car above, a sports striping package is also featured, as are glossy black grille, daytime running lamps, spoiler and mirror caps.
