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.

Watch Jay Leno's Garage work on a Porsche 911 and others

Jay Leno doesn't just own a bunch of cars – he restores them. (Or has people who restores them, at any rate.) For this latest video, he's showing us some of the projects he and his team are currently working on. The tour-de-garage starts with a 1953 Cunningham that had been in storage since '68, complete with a copper grille ready for plating and a 331 Hemi V8. Jay says that every one of the cars that Briggs Cunningham made is still on the road – but that's just one of the dozen or so projects Jay and company are working on. There's a suitably brown '71 Porsche 911 T in near-original condition having sat untouched parked underground in Beverly Hills for decades, and a '58 Chrysler Imperial convertible once driven by Clark Gable and Frank Sinatra, and now getting a brake upgrade. There's a Volvo 122 wagon that's been stripped down, media-blasted, and powder-coated, a thousand-horsepower Rolls-Royce, a 1960 Nash Metropolitan, a supercharged Mercedes-Benz 600 Pullman, and a 1914 Detroit Electric. And those are just the four-wheeled automobiles. Over in the two-wheeler section there's a pair of Brough Superiors, a BSA, an Indian, and a custom racing sidecar that Jay's mechanic Bernard is working on. In short, Jay Leno's Garage isn't just one where vehicles are kept – it's one where vehicles are brought back to life.

Mercedes caught testing stretched E-Class Maybach

The Mercedes-Maybach S600 won't be the only vehicle to wear the hyphenated name of two of the world's automotive luxury greats. That hulking S-Class will soon be joined by an E-Class variant, which should offer the same touch of subtle luxury as its big brother. At least, that's what we're guessing based on the latest round of spy photos, showing a stretched E-Class with some very telling camouflage. Pay attention, as our spies did, to the rear doors and C-pillar. Like the Maybach S600, the E-Class model features a larger quarter window, although unlike the S, the doors here look to be a bit larger than your usual E550 or E250. Also take note of the heavy tint on those rear windows. It's likely there to obscure whatever sumptuous hides and warm woods Maybach has fitted to the typically business-class interior. While the interior materials are likely to see sweeping changes, expect Mercedes to treat the exterior with a much gentler touch. There'll probably be some unique wheels and C-pillar-mounted Maybach badges, like what we've already seen on the S600. Check out the full round of spy photos up top, and stay tuned for more on the latest Mercedes-Maybach. Related Video:
