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-Benz GLE Coupe is ready to tackle BMW's X6

Under the chiseled hood of the GLE 450 AMG sits a 3.0L, twin-turbo V6 with 362 hp and 384 lb-ft. Years after the polarizing BMW X6 originally hit the market, Mercedes-Benz has finally unveiled its slope-roofed challenger, and much like Munich's Sport Activity Vehicle, we think the new GLE Coupe will split opinions rather dramatically. While it clearly shares its form factor with BMW's X4 and X6, the GLE Coupe's styling is all Mercedes, borrowing the more organic shapes used on the company's most recent new model, the AMG GT. Strips of chrome and the iconic silver arrow logo bisect a large, rectangular grille, while the fascia on the GLE 450 shown above features three rather dramatic lower air intakes. The headlights, meanwhile, fit in with MB's latest styling language. In back, slim, wraparound taillights share some resemblance with the new S-Class Coupe. The cabin is recognizable and looks to be of extremely high quality, with the featured vehicle showing off quite a lot of carbon-fiber trim. A thick-rimmed, flat-bottomed steering wheel dominates the driver's area, while a large, tablet-like display crowns the center stack. The same sort of touch-controlled interface and input dial found on the new C-Class controls the information on that screen. Under the chiseled hood of the GLE 450 AMG, the first of Mercedes' AMG Sport models, sits a 3.0-liter, twin-turbocharged V6. Unlike the 329-horsepower unit in the C400 and E400, the force-induced V6 generates 362 hp and an equally robust 384 pound-feet of torque. It's mated up to a new nine-speed automatic transmission and Mercedes' 4Matic all-wheel-drive system. A new version of the popular Airmatic suspension is being offered with the ADS Plus continuously variable dampers while Mercedes is also fitting its Active Curve System, complete with active roll stabilization. Mercedes doesn't provide many additional details on the GLE Coupe range, as it were. We know about the 450 AMG, but it's not clear whether there will be a GLE 400 or non-AMG 450, or if Mercedes will move it down market and offer a GLE 350 to compete with the X6's xDrive35i. There's also no mention of when or where the new model will debut, although previous reports point to the 2015 Detroit Auto Show. Prices and an on-sale date, meanwhile, have not been revealed.

Mercedes 'could' do BMW i rival. But it won't

It's a safe bet that if one automaker does something, its big rival won't be far behind with a response. This is true no matter the country in question. So with BMW's i sub brand enjoying a firm, green standing, it seems like only a matter of time before Mercedes-Benz answers. Or not. Speaking to Autocar, the company's head of sales and marketing, Ola Kallenius, said Mercedes could absolutely conjure up an ultra-efficient sub-brand filled with unique, eco-friendly models to compete with the i3 and i8. Or, you know, it could just apply a fuel-sipping philosophy across the company's range and crush i with a far wider array of models and powertrains. "We could choose for the purpose-made electric vehicles to create some sort of sub-brand but, right now, Mercedes is focused on investing tremendous resources into the path towards zero emissions," Kallenius told Autocar. "It's something that will affect the whole portfolio." And that's not all. "What we're going to do in terms of the road to zero emissions is invest heavily in alternative drivelines and electrification," Kallenius said. "That's a very wide strategy, but it means that by the end of next year we will have 10 plug-in hybrid models, which, I think, is the widest portfolio of any luxury manufacturer." Zing. Kallenius went on to say that on top of the PHVs, MB will sell three all-electric models – two Smart-badged vehicles and the not-for-US B-Class – while its next fuel-cell model, a GLC-based CUV, will hit dealers at the end of 2017.
