Spy photographers have caught images of the next generation 2013 Ford Mustang GT500 rumbling around on public roads.

According to our sources, the next Mustang GT500 could have between 600-625 bhp – though this seems a tall order with the current engine.

This prototype runs on GT500 wheels and Pirelli P Zero tires.

A Lotus Evora GT2 prototype, based heavily on the Evora Enduro GT concept seen during this year’s Geneva Auto Show, was spotted doing laps.

This 2012 Audi A6 Avant prototype spotted undergoing desert testing looks production-ready.

The 2012 Porsche 911 was caught testing at the world famous Nürburgring. The changes aren’t dramatic – they never are with any new 911 – but we like what we see.

We haven’t been able to sneak a peek into the engine compartment, but a slightly more powerful version of the 3.4-liter flat-6 cylinder engine should motivate the base Carrera.

2012 Mercedes-Benz SLS AMG Roadster

Caught wearing almost no bodywork disguise, the SLS Roadster has traditional doors and will feature a powered soft-top. Under the skin is the same mechanical package you’ll find in the SLS AMG Coupe. The SLS Roadster likely weigh slightly more than the coupe; we expect the sticker price to be in the region of $200,000.

Mercedes-Benz brings a bazooka to an archery contest.

In Black Series trim, the 2012 Mercedes-Benz C63 AMG’s snarling engine should produce approximately 510 bhp and offer a top speed well in excess of the standard model’s (electrically governed) 174 mph.

A 7-speed multi-clutch automatic transmission sends power to the rear wheels, and a dial on the center console offers different driving modes that range from comfort to sport, even including a “Race Start” mode for the ultimate in quick getaways.

A BMW spokesperson has now confirmed to Road & Track that the M3 Pickup spotted in Germany is simply a one-off test mule. “BMW M did indeed create the pickup seen on the ’Ring, but it was just an internal project, not something that is in development,” explained Dave Buchko, BMW Advanced Powertrain & Heritage Communications Manager. “There are no plans to produce it.”

A BMW M3 pickup has been spotted doing hot laps at the world famous Nürburgring racetrack. Yes, this is the same V-8-powered BMW M3 that is renowned as one of the world’s hottest, sportiest and all-around lust-worthy German sports machines. And no, this isn’t an early April Fools joke—although we’re still kind of hoping it is.

According to our sources, the 2012 Ford Taurus SHO is set to receive 35 extra ponies (for a total of 400 bhp) and—judging from these photos—an exterior makeover to better differentiate it from the rest of the Taurus lineup. A new cross-hatch grille is visible.

Subtly updated and as extravagant as ever.

The 2012 Rolls-Royce Phantom Drophead Coupe was caught testing. The front grille appears smaller than before, and more smoothly integrated into the gently forward sloping hood and front fascia. The headlights are also updated, along with the lower half of the front bumper.

In terms of the powertrain, Rolls-Royce will likely stick with the 453-bhp 6.75-liter V-12 engine and 6-speed transmission found in the current model.

The 2013 i8, BMW’s new hybrid sports coupe, was caught cold weather testing. Not much appears to have been lost in the translation from show car to production model.

The i8 is one of two vehicles BMW has planned for its new green-minded “i” sub-brand. Lightweight materials—like carbon fiber and aluminum—will make up a big part of the i8’s structure. Exact power specifics have not been released, but BMW has promised that the performance of the i8 will be in keeping with that of the brand’s other sports models.

Although the engine is in the wrong place (the front), this new Volkswagen Microbus looks fantastic, modern while at the same time having the same basic silhouette and seating arrangement as the original.

A personal plea to VW: Build this new Microbus!

Only days after snapping photos of the rakish little Mini Coupe, our spy photographers have caught the Mini Roadster cruising public roads in near-production form. In fact, judging from the spy pics, we’d say the Roadster (even in top-up mode) is pulling ahead of the Coupe in the looks department.
