When asked by thenational.ae if he preferred to drive his McLaren F1 or Mclaren-Mercedes SLR to work everyday, the man who designed both legendary hypercars, Gordon Murray demurs:

I wouldn’t say the SLR is quite an everyday car but I certainly like to drive it to work. But for me, despite all those cars and my single-seater Rocket [a car he privately designed], it’s the [eight year-old Smart Roadster] I’m most taken with. For one, it’s a great-looking car. It has a power roof, heated seats and air con, and it all weighs just 830kg. In fact, it’s got all you’d want from a car. It nips around corners and it’s fun to drive.

So, other than proving that Murray has exquisite taste (I’d kill you all for a Brabus Smart Roadster Coupe), what’s the point? That, having been there and done that in the world of high performance, Murray’s taking on a less obviously sexy but ultimately significant project that first occurred to him in a traffic jam back in 1993: the T.25 and T.27 city cars. We’ve written about Murray’s T.25 before, but the real news today is the release of specs for the T.27, an all-electric version of the tiny three-seater. And yes, it weighs 1,500 lbs on the nose (including batteries), and ekes 100 miles of range out of just 12 kWh. That beats the efficiency of competitors like the Smart EV (by 29%), the Mitsubishi iMiEV (by 36%) and MINI E (by 86%). So, how does it do it?

Smell that? It’s the gathering scent of a new industry trend towards natural gas. Honda’s expanded its pioneering Civic GX to 50 states, Sergio Marchionne wants to replicate his Italian CNG success at Chrysler (eventually), and now GM is jumping on the bandwagon while it’s still relatively uncrowded. The Winnepeg Free Press reports that GM has signed a development deal with Vancouver, B.C.-based Westport Innovations which could see a prototype light-duty natural gas-powered engine completed “within 18 months” if preliminary study proves promising. A Westport spokesman boasts

If both parties agree to move ahead with commercialization this would be one of the first pure OEM [natural gas-powered] products

You know, except the Civic GX which has been prowling American streets since 1998. Still, with Chrysler targeting CNG commercialization no earlier than 2017, GM could have a strong head-start on a fuel technology that promises to be a viable and promising gasoline alternative, especially if the NatGas Bill [PDF] passes, expanding $7,500 plug-in tax credits to natural gas vehicles. And GM’s got a strong partner in Westport, which has heavy-duty commercial deals with Cummins and Caterpillar. With Nissan all-in on EVs and years ahead of the competition in terms of global EV production capacity, look for other competitors to hedge their alt-energy bets… and natural gas is rapidly becoming the most popular alternative.

TTAC’s man-about-the-junkyard Murilee Martin has made the bold claim that we live in the golden age of cheap superchargers, but when it comes to new cars, we may be entering another “golden age” for superchargers as well. Eaton’s Ken Davis tells Automotive News [sub] that his firm is looking at doubling its supercharger sales as the technology comes into its own as a fuel-saving measure. Though turbochargers have received the lions share of attention as the industry moves towards downsized, forced-induction engines, Davis argues that supercharger have their own role to play in the effort, specifically when it comes to “downspeeding” engines to produce better power at lower RPM. He adds

Audi is our largest supercharger customer, and we are on a couple of platforms with Nissan… Nissan will bring their supercharged vehicles here. We’ll be on Audi and Volkswagen platforms, too. We are starting to get some attention.

Speaking of GM’s future lineup, there’s no sign in GMI’s 2013 projected lineup of the on-again-off-again Spark city car (A-Segment) that we had heard would be here now. Hell, they’ve had the cupholders ready since 2009. So what’s the Spark up to?

Having seen its RX-8 banned from Europe for flunking emissions tests, Mazda may be going to extreme lengths to improve the efficiency of its next-gen rotary engine (codenamed 16x) which has been in development since 2007. Autocar reports

The 16X’s capacity has been raised from 1304cc to 1600cc, and it is also physically smaller and partly built from aluminium. The changes are designed to improve two of the biggest issues with rotary engine performance: fuel economy and torque delivery.

The Mazda source said the new engine “needed a smaller hole on the wall [of the combustion chamber]” as a result of eliminating the space-hungry normal spark plug. He also admitted to Autocar that the use of laser ignition “was absolutely possible”.

Recent advances in Japan have created high-power lasers made from ceramics that measure just 9mm in diameter and 11mm in length, easily small enough to fit into a car engine.

Not only would laser ignition allow the 16x to burn leaner, it would also allow more precise control of ignition points and timing. More importantly, it would cement the Wankel rotary’s status as the least-necessary, most overly-complex and thoroughly awesome engine ever created. And they say emissions standards always make cars less interesting…

General Motors CEO Dan Akerson set off something of a firestorm a few weeks ago, when he said, in response to a question about forthcoming CAFE increases:

You know what I’d rather have them do — this will make my Republican friends puke — as gas is going to go down here now, we ought to just slap a 50-cent or a dollar tax on a gallon of gas.

Predictably, populists and economic alarmists of all stripes took great umbrage at Akerson’s candor, questioning his leadership of GM as well as his perspective on the shaky US economy. But Akerson is not alone in his support of some form of gas-tax increase. Bob Lutz and  Tom Friedman (an odd couple right there, if ever there was one) agree with him. Edmunds CEO Jeremy Anwyl defended Akerson and even suggested a $2/gallon tax earlier this year. Bill Ford and  AutoNation’s Mike Jackson are of the same mind as now-retired Republican Senator George Voinovich on the issue. And yet, inside the Beltway, the subject tends to draw a chuckle and a roll of the eyes. Everyone wants it, but nobody wants it.

Cracks continued to in the ethanol industry’s once-impregnable political vanguard, as the San Francisco Chronicle reports that the Senate has voted to roll back the Volumetric Ethanol Excise Tax Credit (VEETC) as well as import tariffs on foreign-produced ethanol. This rollback of multi-billion-dollar ethanol credits failed earlier in the week, when the Detroit News reports automakers came out in opposition of a bill that would have required that 95% of all cars built in the US be capable of running 85% ethanol by 2017. The Senate did fail to pass a repeal of a government ethanol blending mandate that underpins the VEETC, however, and funding is moving forward for ethanol blending pumps. Still, the Senate’s repeal of VEETC alone means taxpayers could save over $5b per year on subsidies, and as one expert puts it

“Looks like we’re going to be relying on the biofuels mandates to make sure blenders use biofuels, rather than bribing them to use it with $6 billion,” [Bruce Babcock, professor of economics and the director of the Center for Agricultural and Rural Development at Iowa State University] said.

In fact, Babcock thinks killing the subsidy could help ethanol because it would come out from the stigma of being a subsidized industry. And removing the subsidy may strengthen support for the mandate, and the tariff on imports.

Over to you, House of Representatives…

Reuters reports that Boston Consulting Group has revised its projections for EV market penetration downwards, concluding that plug-in electric vehicles (including EREV and PHEV models) will make up no more than five percent of the US market by 2020. And ironically, the recent increases in gas prices have actually driven the estimate downwards, as Xavier Mosquet, the global head of the group’s autos practice, tells The WSJ [sub]

Electric cars will undoubtedly play an increasingly large role in many countries’ plans in the decades ahead as energy independence and environmental concerns intensify, but they will gain only modest ground to 2020. Gas- and diesel-powered vehicles are improving faster than expected and will continue to dominate the global landscape.

As the industry (or at least parts of it) and the federal government face off over forthcoming 2017-2025 CAFE/emissions standards, a Center for Automotive Research study is getting more play than ever from an industry that seeks to portray the high cost of fuel economy improvements as being not worth the additional costs to consumers. CAR has yet to publish its full study, but it’s clearly intended to counter an offensive from groups like the Consumer Federation of America, which uses its own study to show that CAFE regulation will actually save consumers money. This battle, over the cost to industry and consumers of passing a 62 MPG standard for 2025, has been playing out for months now, and will continue to go back and forth over the rest of this summer. And sure enough, the Union of Concerned Scientists and the National Resources Defense Council have both hit back against the CAR study, calling it “industry-advocate propaganda” in the Detroit News and arguing that it underestimates future reductions in technology costs.

The WSJ [sub] reports

California regulators want zero-emission vehicles—those that don’t run on petroleum—to comprise up to 5.5% of new-car sales in the state, or roughly 81,300, in 2018. The target would rise annually to 14%, or more than 227,600, by 2025…

Tom Cackette, chief deputy executive officer of the California Air Resources Board, says his agency’s goal is to test whether electric cars can become mainstream vehicles, or wind up serving a “niche” market. Mr. Cackette said the state is investing in charging stations and other infrastructure, and he pointed to the sales of new plug-ins on the market to show that there’s a demand for the vehicles. He said he believes the California targets are feasible.

“That is a question we’ll only find out by trying,” he said. “I think [car companies] are making a pretty big investment in these vehicles, and they wouldn’t be doing that if they didn’t think there was a market there.”

Industry lobby groups are pushing California to roll the ZEV mandate into the forthcoming national CAFE standard. Small automakers like Mazda complain that placing a California ZEV mandate on top of national emissions standards would create a “costly burden…in light of the uncertain marketplace and infrastructure for electric vehicles.” And since CARB is leading the federal government by the ear towards a national standard anyway, it could simply push for a higher CAFE rate, which would at least allow firms the flexibility to comply on their own terms. Adding a major ZEV mandate won’t fundamentally change the national standard, but it absolutely will force automakers to spend huge amounts of money to develop a kind of vehicle that has major shortcomings, is only as green as local electricity generation, and has yet to prove itself with consumers. Whatever you think of emissions standards increases, it should be clear that consumers should determine what mix of technologies can best serve their needs while lowering fuel consumption and pollution.

A pair of studies, by MIT and the International Energy Agency [via GreenCarCongress] take a look at what is rapidly becoming a hot topic in the world of alt-energy transportation policy: the use of natural gas to power cars and trucks. If you’re intrigued by the car industry’s “forgotten” fuel source (and with Honda Civic GX models going on sale in 50 states and a possible $7,500 natural gas car tax credit going before congress this summer, you probably should be), hit the jump for some comprehensive information about the future of natural gas-powered transportation.

When Ford showed the world its new crop of compact-based cars and MPVs at January’s Detroit Auto Show, it announced that its C-Max compact MPV would be coming to the US in 7-passenger Grand C-Max form. But in a strangely prophetic turn of events (see video above), the 7-passenger model refused to show up. Now, according to Ford, the 7-passenger Grand C-Max won’t be coming to the US… instead the 5-passenger version will be sold as a dedicated hybrid model with a plug-in option. Why? Because it’s big in Europe… and because “One Ford.” Hit the jump for Ford’s explanation, and then wonder along with us: seriously, why not sell the 7-seat version too?

Editor’s note: Ladies and gentlemen, for one night only, it’s the return of Curbside Classics to TTAC. You can catch Paul Niedermeyer’s work (along with contributions from an ever expanding crew of TTAC commenters and more) on a regular basis at the new Curbside Classics site. But this piece? It just had to be on TTAC.

There’s a big difference between creating and re-creating. The proto-hot rodders of yore scoured the junk yards for new solutions, not to replicate. The competition was as much in creativity as it was pure speed. Much of that has given way to endless replication, whether it’s a perfect restoration or a 1000 hp resto-mod. But creative juices are irrepressible, and they were certainly at work here. Want a daily driver Edsel, but not its 1950′s fuel-gulping ways? The solution was just a $200 junkyard engine away. But it had to be imagined first. Now that’s creativity, and a harbinger of the future. Which is exactly what the old car hobby needs: a new model, like this “Eco-Boost” Edsel.

At the suggestion of a well-wisher, I picked up the July copy of Motor Trend for my flight back home Iowa yesterday. Though some of the stories showed improvement in that publication’s quality of coverage, the item pointed out by our tipster [online here] was disappointing indeed. The piece, on Fiat’s ongoing acquisition of Chrysler’s equity includes the following paragraph:

Fiat is expected to obtain another 5 percent of Chrysler soon to bring its interest to 51 percent, provided it introduces a 40-mpg (highway) EPA-rated car built in the U.S. wearing a Chrysler brand badge before the end of 2011. With Fiat and Chrysler pulling the plug on electric car development, the 40-mpg car is likely to be a 1.4-liter Multijet-powered Dodge Caliber. The Caliber is scheduled for replacement in model year 2013, so the Multijet version could be a 2012 model only, with the powertrain carried on to its replacement.

So, what’s the problem? Well, as TTAC (and precisely nobody else) has reported, the government’s agreement with Fiat is not for that firm to build “a 40-mpg (highway) EPA-rated car.” It takes some digging through the corporate agreement between Fiat, Chrysler, the UAW and the Treasury, but it’s clear that the government requires that Fiat build a car that tests at 40 MPG combined, using the old “unadjusted” (Pre-1985) CAFE fuel economy rating. Which means that, although Fiat could build a car capable of 40 MPG EPA highway, the government’s agreement requires as little as 31 MPG EPA Combined. Which means M/T’s write-up technically falls on the wrong side of the truth. Although, to be fair, I have yet to find a media outlet that has got this story right…
