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.

New Mercedes-Benz S-Class Coupe spied in revealing state of dress

During a product briefing earlier this year, Mercedes-Benz told us that 2013 would be the "year of the S-Class." Makes sense, too, since the flagship Mercedes is so very close to finally showing its production-ready face. But the high-tech saloon isn't the only S-Class to talk about this year - quite the contrary. Seen here in decidedly revealing camouflage, the new S-Class Coupe will be joining its four-door compadre in the not-too-distant future, as well.
When it launches, the S-Class Coupe will officially do away with the CL-Class nomenclature. This doesn't come as a huge shock. After all, when the new E-Class coupe and convertible were launched, it officially marked the end of the long-running CLK-Class designation.
Thanks to the interesting camouflage seen here, we have a very good glimpse at how the S-Class Coupe will look when all of the molding and swirly paper are peeled off. Rakish body lines pulled from the CLS-Class meet a much more dynamic front fascia. Out back, there are horizontal taillamps rather than the vertical units used on the current car, and the whole package seems very svelte. Our spy photographer even posits that this will be "the best-looking car from Mercedes-Benz in ages."

Mercedes-Benz S-Class spied once again

As evidenced by how little camouflage the next-generation Mercedes-Benz S-Class has been caught wearing lately, it can't be too much longer until the car will get its official debut. In our newest shots of the yacht-sized luxo sedan, the cladding still covers up the headlights, front fascia and most of the rear end, but we finally have an almost undisguised look at the rest of the car's lines.
Considering previous spy shots had more camo that better (or fully) concealed the S-Class' body, some of the more obvious things we see in these images include the prominent grille, the CLS-Class-inspired bodyside creases, the pointed trunk opening and, most interestingly, a lack of fancy exhaust outlets. Unlike other S-Class prototypes we've seen, this car does not have integrated outlets, but it does have two pipes on the left side of the car. All current S-Class models in the US and Europe feature a dual exhaust layout on each side of the car, so while some of our questions about the car get answered, it would appear that more are just arising.
