Mercedes C-Class Cabriolet advances to prototype stage

Following up on last month's sighting of the Mercedes-Benz C-Class Coupe, we've got a pretty sizable update on the C-Class Cabriolet, after a prototype of the new droptop was spotted undergoing testing in Germany. A quick comparison with last year's spy photos shows that Mercedes has made a lot of progress, moving on to full-blown production prototypes with a minimal amount of camouflage. Really, though, we already knew what the C-Class Cab would look like – identical to a C-Class sedan below the beltline, although the tail will likely be a bit more sporting – these spy photos merely confirm that. Expect to see the production C-Class Cabriolet debut at (or more likely shortly before) the 2015 Frankfurt Motor Show, where it will appear alongside the next-generation C-Class Coupe.

Mercedes-Benz Vision Tokyo concept shows us our lazy future

The first autonomous vehicles to hit the road will likely look much the same as the ones we drive currently. But as self-driving technology evolves, so too will the shape of the vehicles themselves. And this is what Mercedes figures that future could look like. The Vision Tokyo concept, so named for the show now ongoing at which it's been unveiled this morning, is an odd yet forward-looking shape, rendered in Alubeam silver and glowing blue. Power comes from a hybrid hydrogen fuel cell and inductive electric charging system that give it a theoretical zero-emissions range of over 600 miles. One look at the lozenge-like shape should tell you that the design is all about the interior space. The driving station – should it be needed – offers a clean dashboard with HUD-only instruments and a central driving position with unobstructed view through the wraparound windscreen. The cabin is clearly focused, however, on the lounging occupants more than on the driver. Accessed via a single, giant gullwing hangar door, the approach is closer to that of a mobile lounge space than a traditional automotive interior, with a wraparound sofa, some manner of high-tech 3D game projected in the middle, and a wide infotainment screen on the inside of the door. The concept clearly foretells of a different future – one that demands less of the driver and offers more relaxed comfort. So while the driver within us grows concerned at his numbered days, the rest can't help but be strangely intrigued. Scope out the live images from the floor of the Tokyo Motor Show and share your thoughts on the concept in the Comments section below.

Pre-Race notes from the 2015 Nurburgring 24-Hours

Autoblog has come to the German countryside to watch the Nurburgring 24-Hour race, and just one day in, we have to say it's outstanding. Le Mans has been the highlight of our summer racing schedule for the past few years, the 'Ring 24-Hour event being the appetizer we always skipped. Earlier this year, however, while visiting Miami to check out the Cigarette Racing 50 Marauder GT S, we met Scott Preacher. He oversees digital marketing for both Cigarette and AMG during the week, then comes to Germany to compete in the VLN race series on the weekends, driving an Aston Martin Vantage GT4 for Team Mathol. If Le Mans is the Oscars of endurance racing, the Nurburgring 24-Hour race is the Screen Actors Guild award – the one voted on by the actors, for the actors. In this case it's the race by the teams and fans, for the teams and fans, even though the increasing manufacturer presence has altered the team equation. We were told that it wasn't so long ago that true privateers could win the overall, but that's not really the case anymore. Front-running teams have heavy factory involvement – Audi Sport Team Phoenix, for instance, which finished in first and third last year, has its own 'Ring race center and is running the 2016 R8; Aston Martin is represented by Aston Martin Racing and Aston Martin Test Center, and Bentley has a Bentley Motors team and uses HPT to run another team. The fan component hasn't changed, though, and you can't talk about the race for more than 60 seconds before someone brings up the battalions of spectators. Every driver we spoke to cited them as the most incredible part of this race after the track itself. It feels to us like a giant German Sebring, with thousands of people camped out in the ginormous, forested infield, many of whom have been here since Monday erecting their ornate camping compounds. There will be parties everywhere Saturday night, and so much bratwurst on the grill that the drivers can smell it when as they're blasting full speed through Wehrseifen. Even when we drove a Mercedes S63 AMG Coupe on a lap before the race, the fans waved like it was a competition. Scott Preacher's Australian co-driver Robert Thompson said, "You come around a corner and it's like you're driving full speed through the middle of a carnival." The race field itself could also be called a carnival, with an officially invited field of more than 170 cars. Even on a track that's 24.4-km long, that's like racing on the 405 at midday.
