US buyers show little interest in big hybrids

The idea of producing large, luxury-vehicle hybrids is turning into a "what were they thinking?" exercise in futility, USA Today reports. General Motors is discontinuing hybrid versions of the Cadillac Escalade, Chevrolet Tahoe and GMC Yukon SUVs, while Mercedes-Benz and Toyota's Lexus division are doing the same with their S-Class hybrid and LS hybrid sedans, respectively. The culprit? Big price increases for fuel economy improvements that border on the unimpressive. Granted, the Escalade hybrid gets 31 percent better fuel economy than the standard version, but that still maps out to a combined fuel-efficiency rating of just 21 miles per gallon. That can be seen as a worthwhile increase, if it didn't cost over $8,000 extra. The 2014 Escalade Hybrid, for example, starts at $74,425 while the non-hybrid can be had for $66,295. Meanwhile, the Lexus full-size hybrid costs $6,000 more than the regular version but only gets 1-2 mpg better combined fuel economy. The result of all these high costs? Low sales. Through April, GM sold 82 of its hybrid SUVs and pickups, down from 541 a year earlier. And the LS hybrid sales were in single-digit territory for April. That isn't stopping Lexus from promoting its hybrids as the right solution (with the wrong facts), though. There are still automakers giving big hybrid vehicles a shot, though. Nissan's Infiniti division is selling a hybrid version of its QX60 and says an impressive 10 percent of QX60 buyers choose the hybrid, which costs just $3,000 more. Looks like money talks.

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 ...

Next Aston Vantage will be the only way to get an AMG V8 with a stick

With only a few exceptions, most of them factory customs, AMG hasn't built cars with manual transmissions. It just isn't the way things are done in Affalterbach. But now that Mercedes's in-house speed shop will be supplying engines to Aston Martin, the world will be treated to cars with three pedals and overengineered German V8s wrapped in a pretty British package. We're into it. The news comes from Car and Driver, which spoke to Aston Martin CEO Andy Palmer about the new Vantage among other things. Palmer confirms to C/D that the Vantage will continue to offer manual and automatic transmissions when the next-gen car arrives featuring the AMG 4.0-liter twin-turbo V8. In its most potent form, the eight-cylinder makes 503 horsepower and 479 lb-ft of torque in the AMG GT S. Figure on a little more from the Aston-ized version, just for fun. The current V8 Vantage GT makes 430 hp and 361 lb-ft from its naturally aspirated 4.7-liter. While some may lament the new engine's forced induction, that added power and the thoroughly modern behavior of the AMG engine should be welcome. While the AMG V8 is currently only planned to go into Aston's entry-level car, C/D does mention a possibility of it (and perhaps its three-pedal transmission) making its way into other cars as an economy option for certain markets. If a V8 DB11 were to be offered, don't expect it to show up here, though. There's also no word on who will supply the manual for the AMG-Aston mashup, but it likely will be a transaxle like the current Vantage. Ex-factory manual AMGs aren't totally unprecedented. Pagani has built some three-pedal cars with its massaged AMG V12s. Compared to those, however, these manual Vantages can be considered mass-production cars. And really, any increase in the number of sticks mated to AMG engines can only be a good thing.
