Sunday Drive: A new Rambo Lambo takes center stage

Surprise! Autoblog readers love fast cars. Doesn't matter what shape; doesn't matter what size. As long as it's got big power, wicked acceleration, and ludicrous speed, you're interested. Take, for instance, the brand-new Lamborghini Urus. It's got a 4.0-liter twin-turbocharged V8 sending 641 horsepower and 627 pound-feet of torque through an 8-speed automatic transmission to all four wheels. It hits 62 miles per hour in 3.6 seconds, and has a top speed of 189.5 mph. Ludicrous speed? Check. And although you'd be hard pressed to draw a line straight back from the upcoming Urus to the old, off-road-ready LM002, at least you can say that Lamborghini does have a history of producing overpowered SUVs. A 5.2-liter V12 engine producing 444 horsepower and borrowed from the Countach certainly qualifies as big power, especially considering this was in the 1980s and '90s. A prime example just sold for nearly half a million bucks. Moving along to more traditional sportscars, we got a sneak peek at the next Porsche 911's interior, thanks to some intrepid spy photographers. And we spy with our little eyes some major changes to the quintessential German sportscar. Finally, we round out this Sunday Drive with two First Drive reports. Both are German, but past that, they couldn't be more different. Either way, ludicrous speed is all but guaranteed by either one.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

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 ...
