Notice a difference between these two pictures? No, not the fact that one is a sexy press shot and the other is a bush-league amateur snap. Both pictures show the 2011 Volkswagen Jetta, but one of them has a torsion beam rear axle, the other has a variation of the Golf’s multilink setup. One has a 2.5 liter blunt instrument of an engine and a slushbox, the other has a high-tech “twincharger” engine that won the International Engine Of The Year award two years running, mated to a dual-clutch ‘box. One has a nasty, plasticky interior, the other offers “higher quality materials and trim.” By now you’ve probably guessed that the less desirable of these two Jettas is the US version, and the fancy-pants version has just been announced for the European market…

No, Virginia, that’s not a turbo Eldo, that’s a turbine Eldo
Paul Niedermeyer’s article and more recent book review concerning Chysler’s Turbine car show that Chrysler was savvy to use it as a halo vehicle – its appeal continues to resonate today. Though we’re learning new details all the time, most car enthusiasts know that Chrysler made a turbine powered car in the 1960s. Less well known is the fact that General Motors also had their own turbine program. While Chrysler’s Turbine Car was mostly a short lived PR effort, it happens that GM had a much longer lasting automotive turbine development program, starting in the 1950s and lasting for at least 40 years, without ever coming anywhere near to production. TTAC commenter jmo, alerted us to the existence of a powdered coal fired turbine powered Eldorado that GM developed after the oil crises of the 1970s, and we were hooked.
Is Sergio Marchionne’s Italy-dissing getting your weekend down? Check out the Italian rebuttal, courtesy of Ferrari’s 458 Italia Challenge, the road-racer version of Maranello’s game-changing supercar. Italy may not buy enough Puntos and Pandas to keep its unions and mass-market brands happy, but it still knows how to produce some of the most viscerally intoxicating automobiles around. And when it comes to weekend entertainment, that’s good enough for us.
TTAC’s Michael Karesh inspired a good deal of jealousy in his Editor-in-Chief a few nights ago by describing his forthcoming RX-8 roadtrip into the hill country along the Blue Ridge Parkway. A zinging rotary engine in a legendarily well-sorted chassis simply screams (literally) for these kinds of driving adventures, and I’d be lying if I said I didn’t briefly donsider ditching my editorial responsibilities and inviting myself along. After all, the RX-8 has been marked for death in Europe and the USA, thanks to the glorious amounts of C02 emitted by its rev-happy rotary mill. This, I thought, is a truly unique car with an engine that might well never be seen again in civilized auto markets. Best to enjoy one while you can, right?
Maybe not. Mazda says that even though its latest 1.6 liter rotary engine is years away from hitting its emissions goals, the brand will never stop trying to bring it to market. Because when it comes to rotary engines, drivetrain boss Mitsuo Hitomi tells Automotive News [sub],
We will never give up
It may not be the most pragmatic approach for a tiny automaker facing independence in a scary-competitive global market, but dammit, you have to respect Mazda’s dedication.
Aston Martin’s decision to sell a worked-over Toyota iQ has raised some serious questions for “brand values” advocates across the internet of late. Does an aristocratic sportscar brand need to take on the problems of urban congestion and carbon intensity? Does the Cygnet’s noblesse oblige PR value outweigh the furor of countless Aston Martin aspirants at the thought of their beloved brand becoming a glorified Toyota tuner house? The answer to both of these questions is apparently yes…

If the recent flap over the Volt’s drivetrain has taught us anything it’s that A) GM’s internal-combustion-assisted plug-in is more complicated than we thought, and B) GM is fine with simplifying its complex reality in order to make it appear as attractive as possible. Which is just fine: they’re the ones trying to sell a $41k car, and as such they’re entitled to do what they can to make it seem worth its many shortcomings. What the automotive media needs to take away from the brou-ha-ha isn’t necessarily that GM’s hesitance to bring forward “the whole truth” is an intrinsically big deal (let’s just say this wasn’t the first time), but rather that knowledgeable writers should focus on explaining the Volt in ways that are both comprehensible and fully accurate. In this spirit, the most important question isn’t “what should we call the Volt?” but “how efficient is the Volt in the real world?”And on this point, there’s plenty of room for some truthful clarification.
The autoblogosphere is agog at the revelation that the Volt’s gas engine occasionally powers its wheels. The GM-created “category” of Extended-Range Electric Vehicles (EREV, or E-REV) as uniquely epitomized by the Volt is suddenly revealed [by Motor Trend via GM] to
[have] more in common with a Prius (and other Toyota, Ford, or Nissan Altima hybrids) than anyone suspected.
So, why did the putative “Father of the Volt” (aka “Maximum” Bob Lutz) tell the car’s primary fan site gm-volt.com that the Volt was born because
My desire was to put an electric car concept out there to show the world that unlike the press reports that painted GM as an unfeeling uncaring squanderer of petroleum resources while wonderful Toyota was reinventing the automobile, I just wanted something on the show stand that would show that hey we’re not just thinking of a Prius hybrid here, we’re trying to get gasoline out of the equation entirely.

For some people (you know who you are), the 200 horsepower provided by the 2011 Hyundai Sonata’s 2.4-liter four-cylinder base engine just isn’t enough. The traditional solution: a V6. But Hyundai, taking a page from Chrysler’s Iacocca-era playbook, has opted to offer a turbocharged 2.0-liter four instead. The specs look good: 274 horsepower at 6,000 rpm and 269 pound-feet of torque from 1,750 rpm. The pricing? Even better. The Hyundai Sonata SE 2.0T lists for $24,865, only $1,550 more than the regular Sonata SE. Are these the cheapest horses new car money can buy in a midsize sedan?

Since we both live in Houston, and I have aspirations of writing more material for TTAC in my copious lack of free time, it only made sense that Sajeev Mehta and I should eventually get together and hang out, so that’s exactly what we did at Ford’s come-kick-our-tires event for the new F150 trucks, including their new EcoBoost (turbocharged) V6 truck engine. Since I’m the epitome of not-a-truck-guy, I thought I’d toss in some random thoughts from somebody coming to this experience completely unprepared for what I was getting myself into.
While my invitation to the media burnout fest musta been lost in the mail, I attended a regional ride/drive event to cover the four new engines in the 2011 Ford F-150 as compared to some of its domestic competition. The afternoon included a fairly-lame autocross, a (short) drag strip and real world tests, unladen and towing. The product specialist made a point to ask everyone to tell their friends about this event. Luckily for Ford, I got a lot of people to tell.
Remember that old saying, “What’s good for GM is good for America”? Well it seems that the UK is developing a similar ethos. “What’s good for Ford is good for the UK”. Now, this isn’t some arrogant Ford executive trying to brainwash the UK public that buying their cars is their public duty. There really is a good reason behind this. Honestly. (Read More…)
What you see above is the cutaway of the Ford 5.0L mill, taken from the 2010 New York Auto Show. Formerly known as the Coyote V8, the 5.0-packed 2011 Mustang GT hit the showroom floors, winning rave reviews with every journalist lucky enough to get their hands on one. While blogging for TTAC at the New York Auto Show, I hit up the Five-Oh engine displays at the Ford booth. It was a thoroughly technical and suitably beautiful exhibit. Only problem was, it gave away a secret that nobody should know. Camera in hand, I did the deed: a picture tells a thousand words, but this TTAC Editorial still needs about 800 words to go with.
According to The Global Times, China’s burgeoning love affair with the automobile is maturing nicely: though sales have slowed in the Middle Kingdom, the engines are getting bigger.
In July, smaller cars accounted for only 65.38 percent of overall passenger vehicle sales, which totaled 946,200 units, declining 1.42 percentage points month-on-month and dropping below last year’s average of 69.5 percent for five months in a row.
“Small cars,” it should be pointed out, means cars with 1.6 liters displacement or less. This despite a 3,000 yuan ($443.37) government subsidy on 71 qualifying “small car” nameplates. And if an uncooperative market weren’t enough to cause some head-wagging in Beijing, only one Chinese-brand car made the China Association of Auto Manufacturers “ten best-selling sedans” list: the BYD F3. And no, not the plug-in hybrid version.
In its first public appearance, the Porsche 918 Spyder prototype delivers an aural experience that its cousin, the GT3 R Hybrid, just can’t match. In fact, at this point it’s probably safe to say that the 918 is already the best-sounding hybrid yet created.

Hi Sajeev, my buddy has a manual-transmission, non-turbo 7M-GE MKIII Supra with about 150,000 miles. Supposedly the previous owner had replaced the head gasket at least once. About a month ago it started smelling like burning oil, and the engine is known for being overly prone to blown head gaskets, so he decided to play it safe and take it off the road within 2 hours of the symptom appearing.
Draining the coolant reservoir revealed a sludgy black substance, which we assumed to be oil, within the coolant. Another strike. The spark plugs, too, were swimming in oil. The rest of the coolant, however, was fine. We could not find any coolant mixed in with the oil, either. Furthermore, there was no greyish/whitish substance around the radiator cap.
Still, we went through the arduous process of removing the head. When the moment of truth arrived, the head gasket was found to be undamaged. And at this point, we’re clueless.
The head gasket needs to be replaced regardless since we’ve taken off the head, which will cost about $500. If we can find out what the source of the issue is, that’s fine. But if not, it may make better financial sense to junk the poor car.
Any idea what problem could be posing as a blown head gasket?
