The writing has been on the wall for some time. Although the Lexus flagship graduated from "concept" to "prototype" when it campaigned in the 24 Hours of Nurburgring, Toyota has refused to even hint at a production date for the V10 supercar. Then Toyota declined to plonk an LF-A silhouette on their Super GT racer, electing to continue with the doomed SC 430 jello mold.

Then news broke that production cars would cost a whopping $225,000, but the LF-A still wouldn't turn a profit. Needless to say, Toyota doesn't like things that are not profitable.

Finally, members of the testing and development crew who have been putting the car though its paces in Germany, as well as test drivers from rival Honda and Nissan crews, have told Autoblog that the LF-A is not destined for the showroom, and will remain only a development platform.

No reasons were given, but we can think of a couple. How many people are willing to part with nigh on a quarter of a million bucks for a Toyota/Lexus? Also, the world's most prolific car maker may not be willing to join the current Nurburgring pissing contest unless it is 100% sure that they can beat the Viper, ZR-1 and perhaps more importantly, the GT-R and upcoming NSX replacement.

Actually, one 'Ring test driver didn't mind going on the record with his opinion. Former Nissan racer, NSX development driver and Nurburgring legend Motoharu "Gan-san" Kurosawa reckons, "Toyota are good at making money, but they're no good at making sports cars."

It just so happens that the all-new 2009 Nissan Murano is one of those nondescript mid-size crossover utility vehicles that may blend into the crowd. Its styling is certainly modern, if not overly exciting. The cabin is accommodating, if not excessively spacious. The handling is inspiring, if not unduly sporty. The engine is strong, and even reasonably efficient. How would this perfectly acceptable, yet hardly over-achieving CUV handle five passengers and full luggage on a 1,000-plus mile road trip across the Southwestern desert? Read on to find out.

The higher-ups at Toyota may have decided to axe the replacement for the Lexus SC convertible, but don't get too used to the idea of a world without a wind-in-your-hair Lexus. Word has it they've given the green light to a convertible version of the current IS sedan. Of course, lopping off the doors and roof of a four-door is hardly unheard of, as that's just what Audi did to make the A4 convertible, but while that 'vert is set to be replaced by the A5 cabrio, Lexus is going the opposite direction.

The IS cabrio is tipped to come in 250 and 350 varieties, with Lexus reasoning that there'd be no market for an IS-F convertible. But fret not, as the same reports suggest that a lightweight IS-F sedan is on its way, again going the opposite way of the Germans as BMW just canceled the M3 CSL program. Things are about to get a whole lot busier at the Lexus plants in Tahara and Kyūshū.

Last September we told you of Volkswagen's plan to overtake Toyota in global sales by 2015. Some Autoblog staffers giggled at the prospect. That was before Toyota reported a 39% drop in profit and began writing down leases, and long before today's news of the Japanese automaker reducing its sales goal for 2009 by almost 7%. Instead of the 10.4 million vehicle sales it predicted for 2009, Toyota says it now may only sell 9.7 million.

While 7% may not sound like a big reduction, consider that Toyota has seen steady growth since its founding in 1934, and any drop is a big deal. Last month, Toyota reported an 18% drop in sales from last July, while VW posted a 4% drop. If those sales rates continue, VW's goal of total domination should be much easier to attain.

Heated seats can be just what the doctor ordered in the middle of winter, but if you're trying to pass on your car-loving gene pool, you may be better off freezing. Scientists studying male fertility have discovered that the proliferation of heated seats raises the temperature of your junk by a full degree Fahrenheit verses sitting in the car without artificially warmed seats. That's enough to cut your chances of reproducing, and it makes us strategically point a fan at close range just thinking about it. Even without electronically warmed seat bottoms, guys that sit in the car for long periods of time raise the temperature of their man parts by a couple degrees above optimal sperm-making levels. Hmmm, just typing "above optimal sperm-making levels" makes us a bit queasy. The cure? Turn off the heated seats, wear boxers, and don't sit in the car for too long at once. OK... lets talk about something else.

Inside Line has the skinny on BMW's new product unveils for the upcoming show season. Paris and L.A. are the headliners, with the City of Light chosen as the backdrop for the official public debuts of the all-new 7 series (including an ActiveHybrid variant) and facelifted 3 Series. While those cars will get their fair share of attention, all eyes will likely to be on the concept X1, which will also make its world debut in Paris.

The baby ute should be to the X3 what the 1 Series is to the 3. As for its "concept" status, if Bimmer concepts in recent years are any indication (think M5, Z4 Coupe, and M3), the X1 show car and production vehicle should be essentially one and the same. The next major unveiling involving a roundel-wearing car will take place this November in Los Angeles, where the redesigned Z4 will be introduced. According to Inside Line, it'll go on sale in January. As for the X1? Time will tell. Details on if and/or when it'll be offered in the States aren't available yet.

Pirelli has announced a further innovation in the ongoing quest to remove the driving from driving. Sensors have been stashed in tires already for the hasty implementation of TPMS, but Pirelli has taken it a step further, putting a sensor package on the tire carcass itself. One implementation of the "Cyber Tire" is the "Lean," which harnesses power from the vibrations of the vehicle and beams information including tire pressure, temperature, and load to the vehicle's computer.

Cyber Tire Lean is setting things rolling for the eventual trotting out of full-blown Cyber Tire, which will be built into the tire. The high tech rubber will be more sophisticated and capable of communicating directly with stability control and anti-lock brakes to improve the effectiveness of dynamic safety systems. Cyber Tire will also carry a three-axis accelerometer that will facilitate real-time calculations of friction coefficients, contact force, and load. Pirelli is most proud of the edge the Cyber Tire will give the nanny systems to catch and correct idiotic driving faster than ever before.

Automakers have been fleeing main-stream media faster than most new reality shows get pulled from prime-time programming. There are many reasons for the move away from big dollar media, including decreased TV viewers and online ads soaking up some of the budget, but perhaps the biggest reason is that cash isn't spewing out of SUV tailpipes any more.

Audi is one company that isn't high-tailing it out of the high rent district. The German automaker won't be cutting its 2008 ad budget, and instead, will be pumping more money into big-ticket campaigns. You'll see Audi touting the A4 at events like the Academy Awards and Sunday Night Football, along with its recent spots during the Olympics and last year's Super Bowl. Audi's goal is to bust misconceptions that it is a near-luxury brand by selling its cars as bigger, faster, and more efficient than the competition.

Audi is in a huge hurry go expand to 1.5m global sales per year by 2015, and it has no intentions of letting something like a massive auto market downturn get in the way of its goals. To reach that goal, Audi will have to fare better in North America, and great products alone won't cut it if the word never gets out.

The Persian Gulf is fast becoming a demanding market for luxury automobiles. So demanding, in fact, that some automakers have begun creating special models just for consumption there. Just days ago we brought you news that Rolls-Royce, having already shipped a golden Drophead Coupe for one special customer, was launching a limited edition Phantom saloon called the Peony edition.

This, however, is not a special Rolls-Royce. We won't list all the ways in which it isn't a Roller, but will save your time and ours by listing instead what it shares in common. It's a luxury sedan, and it's made specially to be engulfed by the Gulf market. That's about it. The Safrane nameplate was previously used for Renault's lackluster flagship sedan, replaced by the reviled Vel Satis in 2000. So what is this exactly that has revived the name? A rebadged Samsung SM5, essentially. That vehicle is produced in an 80.1% Renault-owned joint venture in South Korea. If you're noticing some similarities with our own Nissan Maxima, you've got a keen eye, as it shares its platform with the last-gen Maxima as well as the Nissan Teana (itself available only in the Asian market).

Audi feels that its customer base is smart, sophisticated and tech-savvy, which is why it should love a well designed game for the iPhone that features the 2009 Audi A4. Note the well-designed bit, because that's key. Audi had Denver's Factory Design Labs whip up a driving game that uses the iPhone's accelerometer as a way to steer the new 2009 A4 through slalom courses. The German automaker boasts that development took just two weeks, though after trying the free download ourselves, we think Audi might want to keep that quiet. Game development normally takes much longer - think years - so the two-week gestation of the "Audi A4 Challenge" is rather apparent. In a word: craptacular.

The top-down graphics are boring, and controlling the vehicle might unintentionally accelerate the iPhone right out of your hands. Adding further frustration is speed control that's got two extremes; the scale equivalent of 35 mph, or stopped. While the game is free, it's not worth the time you'll waste. Perhaps they should let the MMI guys have a crack at it?
