BMW's polarizing new 5-Series Gran Turismo hits U.S. dealerships on December 5th, with the 550i GT model being the only variant initially offered. The base price? $64,725. Look for an xDrive variant to come early next year, as well as the 535i GT, featuring an all-new turbocharged inline-six (not the twin-turbo six that we've grown oh so fond of in recent years).

This MSRP slots the 550i GT between the V-8-powered X6 and 750i, but things can start to get rather pricey when options are tacked on. We highly recommend the sport package ($4200) and the optional twenty-inch wheels ($1000), as they vastly improve the 5GT's overall appearance and driving dynamics. Be sure to grab the luxury rear seating package, too ($3950) as it's one of the nicest BMW rear setups we've ever sat in. Seriously -- it's more luxurious than a long-wheelbase 7-Series.

For the full press release and options list, click through the post. And in the meantime, be sure to read our review of the 550i Gran Turismo in the latest issue of Winding Road.

+ First Drive: 2010 BMW 550i Gran Turismo

Mazda has announced that the North American spec Mazda2 (known in Japan as the Demio) will debut at the Los Angeles Auto Show next month. The subcompact hatchback has been successful  in other parts of the world, and will begin to be offered in the U.S. and Canada late next year.

Does this, as well as the arrival of the Ford Fiesta, spell a new trend in the future U.S. auto market?

Porsche has announced the 911 GT3 R. Based on the GT3 Cup S, it is powered by a 480-horsepower, 4.0-liter flat-six. Porsche promises better driveability and easier handling than its predecessor, thanks to ABS, traction control, and throttle blip, making it “more appropriate for the ambitious amateur racing driver.”

The 911 GT3 R is scheduled to debut on January 14, 2010 at the Birmingham Motor Show. It is priced at the current equivalent of $414,950.

Lately, we’ve seen many examples of updated BMWs coming through the espionage pipeline. These latest spy shots, though, aren’t just another appearance update.

Take a close look at the sticker on the window and under the license plate. It reads, in plain English, “Hybrid Test Vehicle.” Caught in Munich, the 1-series appears to be following in the tire tracks of the 7-Series and X6 ActiveHybrid models we have already seen.

We’ll be sure to keep you posted with any more news on the 1-Series hybrid.

-Palm Springs, California

We're fresh from the driver's seat of the newest addition to the Lancer Evo fast family, the mildly more grown up MR Touring model. Mitsubishi has got a lot happening at its event in Palm Springs, California this afternoon (stay tuned for much more from this desert trip in coming days), but we felt we'd be remiss if we didn't check in with a few quick thoughts about the new Evo.

Audi, in what seems to be another step toward making humans obsolete, is developing an Autonomous Audi TTS, which may drive itself up Pike’s Peak late next year.

Audi promises, though, that the project “isn’t aimed at making motorists and the thrill of driving dispensable.” We believe you Audi, and we breathe a sigh of relief. The Autonomous TTS is meant to help improve driver assistance technologies, and what better way to do that than to create a car that needs no driver at all. Amazing what a GPS, drive-by-wire controls, and a big dose of math can achieve.

We drive the 2010 Altima Coupe, Sentra Sedan, and Versa Hatchback back-to-back-to-back to see what the refreshed line is made of.

—Nashville, Tennessee

For 2010, a good portion of Nissan’s lineup has been refreshed. The Altima, Sentra, and Versa, were updated to compete with the ever-expanding sedan market. It had been a while since we’ve been behind the wheel of these three models, so we went down to Nissan’s American headquarters among the rolling, green hills of Tennessee to reacquaint ourselves, and to see what each model had to offer.

2010 Nissan Altima Coupe 2.5S

Definitely the sportiest of the Nissan news in terms of appearance was the 2010 Altima coupe, which drew us immediately. We admit, it’s a good-looking car. It appears confident, but not without a level of restraint. It still has the same form as the sedan, which itself is sleek yet not approaching aggressive. The wheelbase is shorter, and its more compact footprint and two-door profile give a hint of speed to the curve of the cabin.

Today, Hyundai unveiled its first gasoline direct injection engine, the 2.4 Theta II GDI. The 2.4-liter engine, in its current, Korean spec, offers 198 horsepower at 6300 rpm, and 184 pound-feet of torque at 4250 rpm.

Besides its improved output, direct injection lowers emissions and improves fuel economy.

The 2.4 Theta II GDI will see its first application in the first half of 2010 in the Hyundai Sonata. The GDI technology will then spread to other gasoline engines in the Hyundai lineup.

We’re glad to see Hyundai, as well as other manufacturers, bring back the mainstream use of direct injection technology. Learn more about direct injection here, or check out our Direct Injection Buyer’s Guide , listing current models on sale that use the technology.

Not long ago, we sampled a tuned-up version of the BMW 335i in the form of the Dinan S1, and in our non-track test, we actually preferred the hot S1 to that of BMW's already good M3 Coupe.

Tuner ATT Autotechnik has put its spin on the BMW 335i Convertible and the simple modifications are enough to give it a different sort of edge over the stock droptop M3. For starters, power has been boosted to 356 horsepower and 388 pound-feet of torque. And while that may be 58 less horsepower than an M3, the ATT example produces 93 more pound-feet of torque out of the twin-turbocharged inline-six engine. We've discussed the joys of turbo thrust and torque power before, and in some cases actually prefer it to larger-displacement, naturally aspirated mills (though the M3's V-8 is one hell of a good engine), so it looks like this steroid-enhanced 335i cabrio might offer more interesting dynamics for everyday driving.

Other changes include a sharp set of twenty-inch wheels and stainless steel exhaust, giving it a more subdued overall appearance than a comparable M3. Like the Dinan, we can easily see the Doppelturbo-Cabriolet being a more interesting steer than the M-badged Bimmer on the street, but as a track performer, it's hard to say.
