2015 Mercedes C-Class owners reporting bleeding seats [UPDATE]

UPDATE: Daimler AG became aware that, in a small number of individual cases, it is possible for temporary spots and/or shiny patches to form on the man-made leather surfaces of the 2015 C-Class in sub-freezing temperatures. No accidents or injuries have been reported, and we have no reason to believe that there are any hazards to customers. Replacement parts are expected to start shipping to dealers by next week. Owners of the 2015 Mercedes-Benz C-Class are learning the hard way that you don't necessarily want to buy a new vehicle in its first model year. Besides reports of poorly fitting taillights and faulty infotainment touchpads, a number of reports are popping up on the forums of MBWorld.org claiming that the compact luxury sedan's seats are, for lack of a better term, bleeding. Owners of US-built, 2015 C-Classes fitted with MB Tex vinyl interiors are reporting a white, oily, shiny residue discoloring their seats that shows up, often after cold cars are quickly heated. It's important to note that this residue is not necessarily staining the seats permanently – warm, soapy water is often all that's needed to restore the original finish. In other cases, the residue disappears of its own accord, only to reappear in an entirely different pattern. That doesn't make things any more acceptable to owners, many of whom have reached out to Mercedes with complaints. It's not clear how many vehicles are affected, but there are a sizable number of forum threads on the issue on MBWorld alone, and the problem is prevalent enough that Mercedes has issued a technical service bulletin to its dealers. According to the forum postings, the TSB instructs service technicians to replace the headrest and seat cover (except for the front, passenger-side seat bottom because of "factory calibration issues") in affected customer vehicles. New C-Class models in dealer inventories, meanwhile, are to get the soapy water treatment if they're showing signs of the residue. Neither one of those moves seems to represent a long-term fix, though. Black MB Tex seats – both the standard and sport variety – seem to be particularly susceptible to the residue, although we stumbled across at least one image of what looks like Silk Beige MB Tex with speckles of residue.

2015 Bahrain F1 Grand Prix puts a dark horse in the desert [spoilers]

Ferrari's Kimi Raikkonen had said after Malaysia that Ferrari can challenge Mercedes-AMG Petronas purely on pace, beyond the scope of tire wear, in the dry. We didn't see that in China, where Lewis Hamilton easily kept everyone behind and Ferrari's Sebastian Vettel only got close to Mercedes' Nico Rosberg when Rosberg slowed down to conserve his tires. But the Iceman's words seemed prescient during qualifying for the Bahrain Formula One Grand Prix. At the front, nothing has changed so far this year: four races, four pole positions for Lewis Hamilton. Instead of teammate Rosberg next to him, though, he'll look over to see the scarlet Ferrari of Vettel, who took advantage of Rosberg's cautiousness to snatch second place on the grid. In Q2, Rosberg tried to conserve the tires he'd start the race on and said he couldn't get into a groove in Q3, putting in a time 0.147 seconds slower than Vettel. The second Silver Arrows will share his row with the second Ferrari, Raikkonen – yet again – saying he might have left some time on the table during his hot lap but getting around just one tenth off Rosberg's time. Williams is established as the best of the rest behind two teams this year instead of just one last year, Valtteri Bottas claiming fifth ahead of Felipe Massa. Daniel Ricciardo of Infiniti Red Bull Racing said he wants to fight with the Williams', he'll be helped with a good start off the line for the first time this year. Nico Hulkenberg got Force India into Q3 for the first time since the Italian Grand Prix last year and into eighth on the grid, ahead of Carlos Sainz in the Toro Rosso and Romain Grosjean putting in another excellent day's work for Lotus. Come race time, it turned into Mercedes power against Ferrari strategy. When Sky F1 commentator Martin Brundle talks about the Mercedes-AMG Petronas team he often mentions how their engine advantage leads to other advantages throughout the car. Not having to use aerodynamic changes to make up for power unit deficiencies, for instance, means they can run the aero setup they want, which optimizes speed and tire wear throughout a lap. It equates to advantage on top of advantage on top of advantage. That's where Lewis Hamilton is right now, so fundamentally dialed in to his car and his racing that he run the races he wants to run. From the front spot, the Brit ripped off another perfect start and led the field into Turn 1, relinquishing the lead only during pit stops.

Gordon Murray, F1-driven production and .. the Pontiac Fiero

Gordon Murray's design and engineering chops are unquestionable. But does his carmaking approach owe something to the short-lived Pontiac Fiero, a scrappy little car program that emerged from GM against serious resistance? Murray had a Formula One career that ran from 1969 to 1991, with stints at Brabham ('69 to '86) and McLaren ('87-'91), that resulted in several shelves' worth of trophies for the cars he was instrumental in designing. He moved on to McLaren Cars, the consumer side of things, where, during his tenure from 1991 to 2004, he helped design the McLaren F1 and the Mercedes-Benz SLR McLaren, two cars that took learnings from his two decades in Formula One. What do all of these cars have in common? Three things: They are light. They were built in limited numbers. And they were (and are) exceedingly expensive—when the McLaren F1 debuted in 1994, it stickered at $815,000. Murray went on to establish Gordon Murray Design in 2007. GMD has created some interesting concept vehicles, such as the diminutive T.25 city car (94.5 inches long, 51.1 inches wide and 55.1 inches high), and the OX, a lightweight truck for the developing world that packs like an IKEA shelf and is working toward realization through a worthy crowdfunding campaign established by the Global Vehicle Trust. Now he has created a vehicle manufacturing company, Gordon Murray Automotive, that will use manufacturing methods that he developed under the moniker "iStream." Unlike a unibody, there are the "iFrame," a cage-like construction made with metallic components, and the "iPanels," which are composite. The panels aren't simply a decorative skin; they actually provide structure to the vehicle. Presumably this has something of the F1 monocoque about it. Going back to the three elements, (1) this arrangement results in a vehicle that can be comparatively light; (2) Murray has indicated that his manufacturing company will be doing limited-run production; and (3) to launch Gordon Murray Automotive they are going to be building a flagship model, about which Murray said, "With our first new car, we will demonstrate a return to the design and engineering principles that have made the McLaren F1 such an icon." Which seems to imply that it will be on the pricey side. According to the company's verbiage, "iStream forges an entirely new production method that defies conventionality with its Formula One-derived construction and materials technologies." It also sounds a whole lot like ...
