Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.

Next Mercedes-Benz C-Class spotted in the snow

The entry-level Mercedes-Benz C-Class has long felt like nothing more than, well, just that. Aside from the potent and delicious C63 AMG models, there hasn't been much to set the C-Class apart in the entry-level luxury/sport segment, leading to the model being regarded by many as "The Cheap Mercedes." No, it's certainly not a bad car, but for our money, it hasn't stood up particularly well to competitors like the BMW 3 Series or Audi A4.
So with the handsome new CLA-Class coming to round off the entry-level end for Mercedes-Benz, big plans are in store for the C-Class. We can see some evidence of that in this latest set of spy shots from our friends at CarPix. According to earlier reports, the new C-Class will be "far more dramatic" in the visuals department, and while the sedan's sculpting is still covered by camo, the much sleeker headlamp design we see here is, at the very least, a good start. The car's overall size is expected to grow a bit to further distance itself from the CLA, though thanks to lightweight materials, curb weight isn't expected to increase.
Just like the current model, the new C-Class is expected to use four- and six-cylinder engines, both gas- and diesel-fed, and overall power output for the global engine range should span from 120-ish on the low end to as much as 330. These new engines are expected to be mounted lower and farther rearward than before, offering better balance for both rear- and 4Matic all-wheel drive configurations. And as for that AMG? Rumors suggest a turbocharged 4.0-liter V8 will fall underhood.

Mercedes CLA45 AMG Racing is ready for a spot on the grid

Mercedes-Benz trotted out its CLA45 AMG-based racer at the 2013 Frankfurt Motor Show. We first showed you the sedan in the deluge of news and reveals that precedes most good auto shows, and were blown away by the car, formally known as the CLA45 AMG Racing Series.
We were strolling by the Mercedes stand, and figured we'd pop in and take a look at the new racer and its carbon-fiber body panels, gutted interior, and race-sourced aero parts. It's a looker, both as a road car and a track weapon. It's not clear what series the CLA45 AMG will qualify for, although it does seem like a shoe-in for the World Touring Car Championship. Let us know what you think of the CLA racer down in the comments. In the meantime, we've got a full gallery of live images up top, along with the stock images that were posted last week on the Mercedes-Benz Facebook page.
