Mazda has joined the party at the 40 MPG beach, rolling out its new SkyActive engine technology in order to give its Mazda3 refresh a 40 MPG EPA highway rating (with autobox, 39 MPG with manual). Power is up as well with the new engines, generating 155 horsepower at 6,000 rpm and 148 lb-feet of torque at 4,100 rpm. But possibly the biggest Mazda news: as part of its goal to become “the Japanese Alfa Romeo,” Mazda’s stylists have toned down the 3’s goofy grin, giving it a slightly more grave countenance. Again, by addressing the 3’s traditional weaknesses, namely weak fuel economy and overwrought styling, Mazda has helped make the NYIAS a banner year for well-executed mid-cycle refreshes.
Especially since the Legacy/Outback started ballooning and the Forester got a dealer-demanded homogenization, the Impreza has been my personal favorite Subaru (my significant other owns an ’08 wagon). It may not win any fuel economy contests in its size class, but the weight of its AWD system and grunty 2.5 liter engine make it a solid baby grand tourer compared to its front-drive competitors. But with gas prices now climbing steadily towards “freak-out” levels and competitors lounging on the 40MPG beach, a consistent 26 MPG no longer cuts the mustard. And so the new Impreza will lose its 2.5 liter engine in favor of a 2.0 unit which, along with some weight loss and a CVT will power the new Impreza to a 27/36 MPG EPA rating (25/33 with the manual transmission). Far be it from us to complain about less weight and more fuel economy, but it feels like the Impreza may be giving up some of its niche appeal in search of mainstream acceptance… not that there’s anything wrong with that.
As I just noted in my comments on the 2012 Nissan Tiida pictures, the US-market Versa is moving up a class in order to make room for the Nissan Micra, which takes over as Nissan’s subcompact responsibilities by early 2012 at the latest. To celebrate the nameplate’s new importance as a global model, Nissan created this Compact Sport Concept aimed not at the US, but “young customers in emerging countries.” The highlights: it’s a tarted up Micra, rocking the Juke’s lovable 1.6 liter direct-injected, turbocharged engine, making 188 HP, albeit with a CVT transmission. Which is (almost) exactly what I was thinking of when I argued that the marketing-hijacked Juke could have been a “Versa GTI.”
Without the marketers, it’s tempting to believe that Nissan’s engineers would have widened the Versa platform, added the fantastic turbocharged engine, and then decided to simply put a steroidal Versa body on top, creating the king of all B-segment hot hatches.
Few vehicles have been as relentlessly restyled over the past 10 years as Subaru’s Impreza, which has endured five new versions or refreshes since 2001 (including the Mk1). And now there’s a new version, taking styling cues from Subaru’s Impreza Concept as well as (to our eyes, anyway) the first-generation of Pontiac Vibe. Though the front and rear treatments are an improvement on the weakly-detailed current model, the proportions don’t seem to have improved any. And then there’s the under-the-skin issues. That 36 MPG promised by Subaru for the next Impreza comes from a downsized engine (two liters rather than 2.5) and a continuously-variable transmission (CVT). The Outback version, hinted at in this XV Concept, should get less than 36 MPG thanks to its jacked-up ride height, but it’s still not clear whether the 2.5 and manual transmission will continue to be available on the new Impreza.
Bringing out a V6 version of a full-size truck like the F-150 is a good way to get truck guys suspicious, especially if you try to assuage their fears by talking about the engine’s direct-injection, turbocharging and other high-tech frippery. Ford’s solution: emphasize the “power of a V8, efficiency of a V6” simplification, and hope the market catches on as gas prices rise. But does Ford’s marketing concept actually hold true in real life? Does an Ecoboost F-150 get the mileage of a six cylinder even when doing tough truck-guy work? Thanks to some great work by Pickuptrucks.com, you can decide for yourself using the data from a fantastic infographic used to illustrate their test of a loaded and unloaded Ecoboost F-150.
Rising prices at the pump make people do dumb things. Some buy a new car to save at all costs. Not only will they never recoup the cost of the new car, the tsunami in Japan turned fuel efficient Japanese cars into everything else than a bargain. Others do something particularly stupid: They drive their car until it runs out of gas. Read More >
What keeps powertrain engineers up at night? C’mon, get your mind out of the gutter. The move towards downsized, turbocharged engines is creating a number of new engineering challenges, and “torsional excitations” grabbed the spotlight at this year’s Society of Automotive Engineers Congress. Steven Thomas, manager of Ford’s global transmission and driveline, research and advanced engineering, illuminated the issue [via Wards].
As we reduce the engine torque, particularly just off idle prior to the boost coming on, we’re going to adversely impact the ability to accelerate the vehicle. I would challenge you all to think about new ways of dealing with this. We could really use new designs to deal with these challenges to optimize the fuel economy, but at the same time deal with (noise, vibration and harshness) and performance issues presented by these new engines.
The problem: the increased inertia of forced-induction engines. The practical example: a turbocharged Fiesta. A worthy adversary, a worthy cause. Let’s do this. Read More >
In the grand old days of the European auto industry, rival houses would battle for supremacy in endurance, road, rally and formula racing, the results of which were treated as far more important than (or, at least the basis for) such prosaic concerns as sales volume or profitability. In the modern era, this fierce competition slacked, as racing became about brand-building and competition moved into the arenas of sales and profits. Now, however, a new competition has erupted between every brand with a presence in the European market, only this time participation is compulsory and the stakes are survival in a super-competitive, mature market. And neither speed nor endurance will win this race against time: only reaching an EU-mandated carbon emissions goal by 2015 will do.
If Chrysler’s five-year business plan were taken at face value, one might be forgiven for thinking we were supposed to have a four-cylinder, stop-start-equipped diesel Wrangler in the US by now. Not so, clarified Jeep’s bosses, while keeping the window open. Now Jeep CEO Mike Manley is hinting at diesels again, telling the Freep that the Wrangler and Grand Cherokee could get oil-burning engines “within three years,” and that
Diesel in some of our models makes absolute sense.
Europeans certainly seem to think so, as the vast majority of Jeep sales on the continent are diesel models. And no wonder: on the European test-cycle (non-EPA), the 3.8 liter gas-powered Wrangler (with manual) is rated at 15.5MPG city, 29 MPG highway and 22MPG combined, while the diesel 2.8 with manual and stop-start (offering less horsepower but more torque) is rated at 28.5MPG city, 36.2MPG highway and 33.1MPG combined (converted from l/100km figures). It might not be long before that kind of efficiency advantage becomes worth the $1k-$3k projected price premium (assuming the EPA test reflects an equal advantage).
The Environmental Protection Agency has revised its alternative-fuel conversion regulations for light and heavy-duty vehicles, making it easier for manufacturers to sell conversions that are compliant with clean-air laws. The 186-page ruling provides an exemption from a Clean Air Act prohibition against tampering when converting an engine to run on alternative fuel.
In the past, a manufacturer of alternative-fuel conversion systems was required to certify its products in the same manner that a vehicle manufacturer certified its vehicles — an expensive and difficult process. The new regulations provide a way to comply with clean-air standards through streamlined testing.
In essence, the rule change creates a graded compliance structure, depending on the age of the converted vehicle, making it easier to retrofit older vehicles. Read all about it at the EPA’s website.
Compared to March 2010, Ford enjoyed the greatest improvement in sales-weighted fleet MPG in the US market on an adjusted (EPA) basis. But the new king of efficiency, Hyundai, also saw its fleetwide efficiency improve, rising to 26 MPG, some 1.9 MPG better than the next closest competitor, Honda. No wonder the Koreans are the first (and only) automaker to disclose its CAFE fuel economy (as well as the first automaker to publicize the difference between CAFE ratings and the adjusted numbers you see here). For the first quarter of this year, Hyundai’s CAFE rating (as calculated by the automaker) stands at 35.8 MPG, with some 22 percent of its sales mix coming from vehicles rated at 40 MPG on the highway (28% for March).

In the post-Veyron, post-Horsepower Wars world, “Responsible Performance” has been the catchphrase on the lips of every purveyor of performance cars. And with Audi and Nissan already set to brawl for EV sportscar niche that’s being abandoned by Tesla with the forthcoming end of production of its Roadster, diesel power seems to be benefiting from a second look by would-be “responsible performance” vendors.
Unsurprisingly, the tuning houses are promoting their diesel efforts, as EV tuning presents significant challenges to the ICE-based tuning community. And the BMW modifiers at AC Schnitzer are leading the way with this Z4 “99d,” a 188 HP, 310 lb-ft two-liter turbodiesel roadster capable of 146 MPH. Oh yes, and 99 grams of CO2 per Km, or (very roughly) 60-ish MPG (non-EPA). Sound like a healthy compromise between “responsibility” and performance? The only thing you’ll have to give up is the $210,000 that Automobile says this Schintzer concept would cost if it were built.
A new report [full PDF here] from the Government Accountability Office tears into the Department of Energy’s Advanced Technology Vehicle Manuacturing Loan (ATVML) program, the $25b “retooling loan” package that was the subject of TTAC’s first-ever Bailout Watch.
Although the loans represent about a third of the $25 billion authorized by law, the program has used 44 percent of the $7.5 billion allocated to pay credit subsidy costs, which is more than was initially anticipated. These higher credit subsidy costs were, in part, a reflection of the risky financial situation of the automotive industry at the time the loans were made. As a result of the higher credit subsidy costs, the program may be unable to loan the full $25 billion allowed by statute.
As I write this, President Obama and his top environmental and auto regulators are gathering for a speech on “American energy security” at Georgetown University. In this speech, the President is expected to make the case for ramped-up CAFE standards, EV subsidies and other transportation-related energy efficiency goals, and based on his politically pragmatic framing of the issue as being about “energy security” rather than environmental prerogatives, it seems that he’s serious about creating new policy rather than merely playing to his base. But, according to the Detroit News, the automakers are not going to take increased regulation sitting down, but appear to be gearing up for the first major legislative clash over automotive regulation since the green-tinged bailout. Automakers have begun to push back on both fuel economy and stalled safety legislation, explains Alliance of Automotive Manufacturer’s spokesperson Gloria Bergquist.
Automakers have always supported legislation and regulations that are driven by data and sound science, and there have been some examples where there was more wishful thinking and targets being selected that weren’t based on the data. So we have become more outspoken on the need for data to drive policy decisions.
Of course, automakers haven’t always supported regulation of their industry… but this is clearly a change in tone from the cowed industry that collapsed into the government’s arms just a few short years ago. A battle is brewing, so let’s look at some of the flashpoints in this forthcoming conflict.
During an interview this year at the Detroit auto show, Jamie Hresko, then vice president of GM global powertrain engineering, strongly suggested the automaker was exploring a new mid-sized pickup. He resigned in late February to pursue other opportunities.
To meet proposed higher U.S. fuel economy and lower emissions standards, automakers that sell in the United States eventually will need to develop a leaner range of pickups, Hresko said.
At some point, especially with the likelihood of higher gasoline prices down the road, a smaller, lighter-weight pickup is inevitable…
