At long last, a hardcore, track-ready version of the latest BMW M3 Coupe has been released, set to go on sale in the Spring of 2010. But unlike the M3 CSLs of the E46 generation, this new M3 GTS is significantly lighter, more powerful, and has a long list of track-friendly upgrades.

Under the hood, the standard 4.0-liter V-8's displacement has been increased to 4.4 liters, meaning output has been increased from 414 to 450 horsepower. All of that shove is being routed to the rear wheels via BMW's M DKG Drivelogic dual-clutch gearbox, though the characteristics have been specially tuned to match the GTS's extra power and performance.

Power upgrades are one thing, but when it comes to track cars, lightness is key. The M3 GTS weighs slightly less than 3300 pounds, and while that may seem pretty porky, remember that the standard M3 Coupe is around 400 pounds heavier. What's more, the GTS uses a heavily upgraded suspension and high-performance brakes, along with special nineteen-inch wheels. Naturally, another strong point of the GTS's performance is in its aerodynamics, and with just a quick glance at this car, it's easy to see that the aero design is heavily based on World Touring Car Championship vehicles, like the 320si.

We're putting on our Pilotis and helmets in anticipation of a track day with this hot little number. No word on pricing has been released at this time, but for the full details, click through the post to read BMW's press release.

Oh, the Porsche Boxster. As we recently reaffirmed in our latest comparison test, the little two-seat roadster from Porsche is one of our favorite topless road cars, and now there's more to love. The much-anticipated Boxster Spyder won't make its official debut until December 2nd at the Los Angeles Auto Show, but the details and images have already leaked out ahead of time.

This lightweight, hardcore version of the Boxster starts with the well-received 3.4-liter, direct-injection flat-six engine, though power has been increased by 10 horsepower for a new total of 320. Combined with Porsche's PDK gearbox and Sport Chrono package, the Spyder will jaunt from a stand-still to 60 miles per hour in just 4.6 seconds and will do 166 mph flat out (with the roof off, of course). "Roof," though, is a figurative term with the Spyder, as the Boxster's standard folding lid has been replaced with a lightweight soft top that acts as more of a sunshade than anything else.

Other modifications include a special sport suspension which lowers the ride height by twenty millimeters, a standard limited-slip differential, and exclusive wheels. Aluminum door skins and lightweight interior door panels (from the GT3 RS) aid in reducing the Spyder's weight by 176 pounds over the standard Boxster S, and with a lower center of gravity, we're confident in saying that this thing will be well-suited for hot laps at your local track.

Look for the Boxster Spyder to hit U.S. showrooms in February of 2010 with a starting MSRP of $61,200. Click through the post to read the official press release from Porsche.

As it stands, the BMW 135i is a potent little machine with its 300-horsepower, twin-turbocharged inline-six. But what about an M version? Sources inside of BMW are now reporting that a 1-Series M might not be too far off, and that the M1 moniker could possibly be brought back, much to the dismay of original M1 enthusiasts.

Speculation suggests that a new M-badged 1-Series would use the same twin-turbo six as the 135i but that power could be increased to around 330 horsepower. A source at BMW's M division says, "We're looking at ways to attract new customers to the brand, and an entry-level model is part of those plans." Naturally, a new "M1" would be priced under the current M3, so the mid-$40K price range is probably as good a guess as any.

Consider our interest piqued.

As if the too-hot Roush 427R wasn't enough, the much-loved tuning company has now put another spin on the 2010 Mustang. As for appearance, this one is much more tame and subtle than some of the cleft-chinned 'Stangs we've driven, but don't let its looks fool you. The supercharger under this Mustang's hood bumps up power to a GT500-matching 540 ponies, and with suspension tweaking on hand, this latest Roush will surely be a hit for muscle car enthusiasts.

Scoot on over to our Ask It forum post and let us know what burning questions you have about the newest Roush creation. We'll be on hand to respond, as well as post driving impressions throughout the week.

Here, we see the successor to the Ferrari 612, which we saw once before earlier this year. This test mule has a longer wheelbase than the 612, which could mean more passenger volume, or Ferrari could be making room for a KERS system. It also has the over/under style tailpipes.

Our photographer also offers the possibility of Ferrari’s four-wheel-drive system, compatible with front- and mid-engine vehicles.

Interestingly, the stickers on the steering wheel warn that the engine should only be started with the hood closed.

We’re making our lists a little early this year, as Tesla can only promise delivery of our custom Roadster by the end of the year if you order today (October 28) by eight o’clock Eastern.

Oh, and if you live in Colorado, you may be eligible for a $42,000 tax credit.

Still can’t justify it? A subscription to Winding Road also makes a great gift for discriminating drivers.

After many, many rounds of spy shots, the final details and production images have been released of the much-anticipated Lexus LFA supercar, which will have a limited production run of 500 units and will be sold for -- get ready -- $375,000. (Start saving your pennies.)

The details on this thing are nothing short of supercar stock, though its front-engine, rear-drive configuration is a change of pace from the Audis and Lambos that we've learned to love. Still, having 560 horsepower and 354 pound-feet of torque is nothing to frown at, especially in a car that only weighs 3263 pounds and revs up to a screaming redline of 9000 rpm. 0-62 miles per hour? 3.7 seconds. Top speed? 202 mph. We're ready for some track time.

If you have the money, you can put an LFA in your garage starting in early 2011 and take it Nissan GT-R hunting. Click through the post for the full press release and scroll through our gallery of images above to see the LFA from all angles.
