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 ...

Mercedes G 500 4x4 is mighty mean and bright lime green

The Mercedes-Benz G500 4x42, finally ready to meet the crowds at the Geneva Motor Show, might just be the best factory-prepped expedition off-roader on the market, should Mercedes choose to build it. The short story is that some well-heeled admirers of the G63 AMG 6x6 said, "It's nice, but can you take it down a notch?" And by "notch" they meant "an axle." So the G500 4x42 gets just two portal axles instead of three, and a slew of other features. The 4x4 squared offers up a standard G-wagen body, but instead of the 5.5-liter twin-turbo V8 from the G63, there's a new 4.0-liter twin-turbo V8 with 422 horsepower and 450 pound-feet of torque. Compared to the standard G500, the track is 11.8 inches wider, the street-cred rims being 22-inchers on 325/55 R-series tires. When it's time to get dirty, they can be swapped for an optional set of 18-inch wheels with 37-inch beadlock tires. With that setup and the same wheelbase as the G500 LWB, ground clearance and fording depth are more than doubled to 17.7 inches and 39 inches respectively, the angle of approach goes from 36 degrees to 52 degrees and the angle of departure leaps from 27 degrees to 54 degrees. Breakover angle is bumped from 21 degrees to 47 degrees, a two-piece stainless steel undertray protecting the sensitive bits when you push it. The only parts that get a raised eyebrow are the carbon fiber wheel arches and bumpers, which might behave badly when they meet an immovable granite object. To escape the sensation of driving the Taj Mahal in urban environments, there's a twin spring-and-damper setup at each wheel. One of the spring-damper combos is electronically controlled and adjustable, and when called into action via the Comfort or Sport mode, takes control of wheel action; even when passive, it will kick in to automatically to stiffen the body if it detects evasive maneuvers. On top of all that, to remind you that you're in a Mercedes the interior is fitted out with Designo leather trim and diamond-quilted microfiber. Mercedes is going to gauge its Geneva reception before deciding to build it, a hurdle we're sure will be overcome. Car and Driver drove it and verified it's the real deal, with pricing - if it's built - speculated to land between the G63 AMG and G65 AMG. The press release below has all the details.

Mercedes rules out hybrid supercar, promises SLS successor

The recent Geneva Motor Show was a festival of hypercars, with the presence of not one, but three over-the-top debuts: the Lamborghini Veneno, McLaren P1 and Ferrari LeFerrari. The latter two have hitched their carbon fiber bumpers to the electrification bandwagon by using hybrid-electric powertrains not entirely unlike the propulsion systems we've come to know in cars like the Toyota Prius and Chevrolet Volt. Does that mean the flow of electrons up the four-wheeled food chain will eventually consume our hallowed supercars? Not if AMG has anything to say about it.
AMG Director of Vehicle Development Tobias Moers recently confirmed that not only will there be a successor to the Mercedes-Benz performance division's SLS AMG, he notes that its internal combustion engine will most definitely not be sharing living quarters with an electric drivetrain. Instead, AMG plans to focus on further pushing the power and efficiency envelope of the internal combustion engine and advancing the use of lightweight materials to achieve their goals. The first example of this effort can be seen in the new SLS AMG Black Series that incorporates many weight-saving techniques to shed some 154 pounds from the SLS AMG GT (above), which itself is lighter than the standard SLS AMG.
Furthermore, Moers remarks that his company is happy to leave the hypercar segment to companies like Ferrari and McLaren. He admits that, "Ferrari in the hyper-car segment is still a different brand than AMG. We have to be honest..." So rather than taking the SLS further upmarket to do battle with bulls and stallions, Moers hinted that the next-generation SLS may be joined by another performance model that fits neatly between itself and the C63 AMG.
