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.

Mercedes considering convertible SUV

Mercedes has been focusing a lot of attention lately on revitalizing and expanding its crossover and SUV lineup. So what's next for high-riding Benzes? It could be a convertible. According to Daimler's sport-ute and sports car chief Wolf-Dieter Kurz, the company is closely considering a drop-top SUV of some sort. "We will find a market," Kurz told the Australian website CarAdvice. The trouble is that "the convertible is a very slim niche in terms of the SUV portfolio." The biggest problem could be China, where luxury SUVs remain hugely popular – but where convertibles, by and large, are not. "There are lots of discussions," said Kurz, "but we didn't have any decision yet." The last time Mercedes offered a convertible SUV was with the short-wheelbase version of the Gelandewagen, pictured above. It was available (in some markets anyway) for 34 long years as part of the G-Class lineup, but was discontinued in 2013. That left the Jeep Wrangler and Land Rover Discovery as the only convertible SUVs to speak of currently available. Nissan tried its hand with the Murano CrossCabriolet, but that was phased out as well, while Land Rover prepares to take another stab at it with the upcoming Evoque convertible. It'd be interesting to see what approach Mercedes might take, and where it would position the model. Related Video:

2015 Mercedes-Benz CLS400 [w/video]

Rocky IV debuted in 1985 but it was a few years later that I first watched it, on video. I loved every second of that terrible movie. I loved Drago's super-high-tech demonstration of punching power. I loved Rocky training in a Russian barn, with ropes, and yokes, and wagons. But mostly I loved Brigitte Nielsen. My 10-year-old brain sweated her impossible combination of curves and sharp edges, demure eyes, and sculpted bone structure. The perfect woman, but evolved by the power of the dark-hearted Soviet Union (or Denmark, whatever, I was ten). Red Sonja has a lot in common with the latest version of the Mercedes-Benz CLS, as I see it. Mercedes created a new market niche with its first four-door coupe, a sedan so well-proportioned, flowing, and femininely curved that it could pull off its inaccurate moniker. The third evolution of the CLS you see here has Nielsened up the shape into something altogether more angular and edgy, but like 1985's Brigitte, retains an undeniable sex appeal. It's a more opinionated piece of auto design than was the original CLS. And also a car that bifurcates the space between luxury coupe and luxury sedan. Ludmilla Drago would undoubtedly understand. Driving Notes For the base engine of a 4,200-pound car, the CLS400's two-turbo V6 does better than just get out of its own way. The full 354 pound-feet of torque is available way down at 1,600 revs, and plateaus until 4,000, giving you a fat band in which to call up power. Acceleration is available in the form of a quiet, gracious, but not aggressive push at just about every speed. From inside the cabin, the engine and exhaust noises are pleasantly rumbling, though muted. But do yourself a favor and try not to listen to the CLS tick over while standing around the driveway. When the car first pulled up in mine, warm from some 40 miles of highway, it still sounded an awful lot like a 2.0T on a mid-March morning. Not to belabor the Brigitte metaphor, but I found as much Neilsenian dichotomy in the ride and handling as I did the exterior styling. Especially with Mercedes' 4Matic system spreading out the grip, I found the CLS to be sharp when pushed, and rather excellent in terms of making quick corrections while under a cornering load. And yet, you've got to push through an initially soft suspension response to reach that hard edge. The CLS will initially resist being tossed around a winding backroad, but press on and she'll do as you ask.
