Our spy photographer just sent us these photos of the updated BMW M5 wearing a little bit less camo than usual. Besides shedding those ugly clothes, it may also be shedding some pounds, and two cylinders; rumor has it the new M5 will be powered by a twin-turbocharged V-8 engine, instead of the thirstier and heavier 5-liter V-10.

Earlier, we showed you a white Lexus LF-A supercar lapping the Nürburgring. Now we have caught it in matte black, which gives a little more visual definition to the car’s form. Also, in these photos, we get a good look at that deployable wing in both positions on the rear end. Very interesting.

The Mercedes-Benz SLS AMG gullwing debuted at the Frankfurt show this month, and now our spy photographer caught the SLS Roadster out testing near the Nürburgring. We’ve seen it once before, stopped near a Mazda event with the gullwing version.

We expect the SLS to have put on some weight in convertible form, as added bracing is required to stiffen the body. We’ll have to wait until we get more information to find out how performance is affected as a result.

The first thing we notice about the new Audi A8 is the updated headlamps with LED running lights. The camouflage hides any other obvious changes to the vehicle, but our photographer notes that it has gotten slightly longer and lighter.

We expect some updates under the hood, and the car should be more efficient than previously. Also, we should see two- and four-wheel-drive versions. If all goes as expected the new A8 will show up later this year.

Land Rover is moving forward with the production version of its very sexy LRX concept, though the small SUV may be headed in a very different direction than the concept would indicate.

The test mule seen here is most certainly based on the Land Rover LR2, which could indicate that Land Rover is backing off the three-door, coupe-like concept that the LRX was first proposed to be. We can see that this tester has been shortened, perhaps giving a flicker of hope to those waiting for the LR coupe. Be it three- or five-doors, expect that the new vehicle will at least share a profile much closer to the sleek LRX, as even this mule has had its rea end reshaped considerably.

We just received these photos of the Renault Megane CC, which was expected to show up at the Frankfurt show, but didn’t. Perhaps they didn’t have room for it on the show floor.

We expect the rear end of the CC to differ from the Megane Coupe to accommodate for the retractable roof, which should be partly made of glass.

Look for gasoline and diesel engines, as well as a biofuel powerplant.

Longtime Winding Road reader, Mokoto Kojima, sent us these photos of the new Jeep Grand Cherokee cruising around in Southeast Michigan.

Jeep announced the updated Grand Cherokee a few months ago, and we’re excited to see it right on our doorstep. It’s looking good, too, from what we can tell from the pictures.

The 2011 Grand Cherokee features a new Quadra Lift air suspension for on- and off-road versatility, giving it up to 11.1 inches of clearance. The unit in these photos appears to be riding pretty high.

The new Grand also offers three different 4x4 systems, and an available flexible fuel powerplant.

Thanks, MK!

In concurrence with the 2009 Porsche Boxster S being in our fleet, we now have spy shots of the Boxster Speedster. We notice a few fun alterations, such as the lower windshield and a minor nosejob. We imagine the Speedster has also probably shed a few pounds. Perhaps Porsche will wring out a few extra ponies to sweeten the deal. We’ll have to wait on confirmation of those details, though.

Our spy photographer sent us these shots of the BMW Z4 with the performance-oriented M package. We don’t have the specifics on the upgrades for the new Z4, or how similar it will be to the previous Z4 M (330-horsepower, 3.2-liter inline-6). We can tell from the photos, though, that it has some slight aesthetic changes, particularly around the nose area.

Notice the blacked-out grille, and the open look of the air intakes (always a good sign). It looks at home on the Nürburgring, but we think it would look more at home in the Winding Road parking lot.

We're still waiting for photos of Paulina Zemcova awkwardly draped across the hood. We'll keep you posted.

It’s been quite a while since we’ve heard anything new regarding the efforts by Lexus to bring its near-supercar LF-A to production—leading many to speculate that the project had been put on the shelf because of worldwide economic instability. So you can imagine our surprise and delight when we awoke this morning to find brand new spy shots of the car gracing our inbox. Even better, the photographs show an LF-A wearing basically no camouflage whatsoever. Game on.

To refresh your memories, the LF-A is a “front mid-engined” monster of a thing, reportedly making use of a 550-plus horsepower, 4.8-liter V-10 engine, and capable of lapping the Nürburgring in times that could shame a Porsche GT2. We also find this new example to be rather comely, albeit in a rounded-corners, Lexus-style supercar way, despite the fact that it’s been painted form-hiding white.

Take a close look at the naked LF-A in our gallery above, and then wax excited about the return of the super Lexus in our comments section below.
