Mercedes SLS AMG Gullwing White Prototype Spied Again

While we've already seen this particular mule before, our spies have managed to take additional pictures which show a better view of the grille, headlights, and rear end. Although they were unable to get a glimpse of the interior, Mercedes already released official press photos of the SLS cockpit last month.



As previously reported, the new supercar features a naturally aspirated front mid-mounted 6.2-liter V8 engine which produces 571 hp (420 kW) and 650 Nm (479 lb-ft) of torque. Thanks to the combination of a powerful engine and an advanced seven-speed double clutch transmission, the SLS AMG Gullwing rockets from 0-100 km/h in 3.8 seconds before hitting a top speed of 315 km/h (196 mph).



Expected to be unveiled at the Frankfurt Motor Show in September, the SLS AMG Gullwing will go on sale next year with a base price somewhere in the neighborhood of €150,000.

Rendered Speculation: 2011 BMW 6-Series

Some new artist rendering have surfaced showing what BMW's upcoming 2011 6-Series may look like.



While they're just one artist's interpretation, recent spy photos have shown the new 6-Series will feature aggressive styling that adopts several design cues from the Z4 roadster, 7-Series, and the CS concept.


Engine options will likely carry over from the current 6-Series, but the 360 hp 4.8-liter V8 will be replaced by the new 400 hp twin-turbo 4.4-liter V8 from the new 7-Series. The M6 is also expected to drop its V10 engine with 500 hp and 383 lb-ft of torque for a slightly retuned version of the X5 M and X6 M's new 4.4-liter twin-turbo V8 engine with 555 horsepower and 500 lb-ft of torque.

New Porsche 911 (997) GT3 RS Facelift Spy Video

ach year from about this time of year the Nurburgring is abuzz with activity from automakers wanting to hone their upcoming cars on the famous track. Porsche of course is one of the main culprits. This spy video from UK CAR shows the new facelifted Porsche 911 GT3 RS going through its usual paces through the track. The sound alone makes for exceptional viewing so you can even "watch" the video clip without the picture.

The new GT3 RS has GT3 blood running through it but is a bit different. It will have a massive rear spoiler which seems to have been built of carbon fiber. Deeper side skirts and wider rear bodywork give the GT3 RS a squat fit for a very sharp track tool.

The car will lose a few kilograms and gain more speed. The GT3 facelift already kicks out a suitable 435hp (320kW) from its 3.8-litre flat six engine. In its best form the RS should be able to go from 0 - 100km/h in about 3.8 seconds.

Among all the other hot cars expected to make their debuts at the 2009 Frankfurt International Motor Show in September will be the GT3 RS facelift. It seems like a long while to wait but when it comes to all things Porsche time just seems to fly.
