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.

These are the cars with the best and worst depreciation after 5 years

The average new vehicle sold in America loses nearly half of its initial value after five years of ownership. No surprise there; we all expect that shiny new car to start depreciating as soon as we drive it off the lot. But some vehicles lose value a lot faster than others. According to data provided by iSeeCars.com, trucks and truck-based sport utility vehicles generally hold their value better than other vehicle types, with the Jeep Wrangler — in both four-door Unlimited and standard two-door styles — and Toyota Tacoma sitting at the head of the pack. The Jeep Wrangler Unlimited's average five-year depreciation of 30.9% equals a loss in value of $12,168. That makes Jeep's four-door off-roader the best overall pick for buyers looking to minimize depreciation. The Toyota Tacoma's 32.4% loss in initial value means it loses just $10,496. The smaller dollar amount — the least amount of money lost after five years — indicates that Tacoma buyers pay less than Wrangler Unlimited buyers, on average, when they initially buy the vehicle. The standard two-door Jeep Wrangler is third on the list, depreciating 32.8% after five years and losing $10,824.

On the other side of the depreciation coin, luxury sedans tend to plummet in value at a much faster rate than other vehicle types. The BMW 7 Series leads the losers with a 72.6% drop in value after five years, which equals an alarming $73,686. BMW's slightly smaller 5 Series is next, depreciating 70.1%, or $47,038, over the same period. Number three on the biggest losers list is the Nissan Leaf, the only electric vehicle to appear in the bottom 10. The electric hatchback matches the 5 Series with a 70.1% drop in value, but since it's a much cheaper vehicle, that percentage equals a much smaller $23,470 loss.

Mercedes-Benz C-Class 'bleeding seat' problem resurfaces [UPDATE]

UPDATE: We received the following statement from Mercedes-Benz: "In rare instances, we incorrectly ordered some of the replacement parts for the seating surfaces. The approved replacement parts will not demonstrate the previous symptoms." It appears Mercedes-Benz has another problem with "bleeding seats" in 2015 C-Class sedans. As we reported in January, an oily residue has been appearing on some versions of the C-Class with man-made MB Tex upholstery, making it look as though the seats were grimy or "bleeding." Mercedes issued a technical service bulletin to its dealers to remedy the problem, but now we're hearing the fix isn't complete. Small parts of the seats – the rear bolsters and a piece below the center armrest – weren't replaced during service and then developed the oily reside again, a source tells us. This occurred within a few days of their service appointment. The dealer followed Mercedes' instructions, our source said, and their C-Class appears to have been one of the first cars fixed. "I'm absolutely flabbergasted at this point ... The new C-Class is such a good car. This is just a shame," they told Autoblog. The bleeding seat issue appears to affect US-built C-Class models with the MB Tex vinyl and possibly other interiors. The bleeding often occurs when a car has been sitting in the cold and then heats up quickly. The number of cars affected is unclear, though the C-Class owners have been vocal in the MBWorld.org forum. At the time of our original report, Daimler AG, parent of Mercedes-Benz USA, said it was aware of the issue and that no injuries had been reported. The residue usually washes off with soap and water. The National Highway Traffic Safety Administration had no recalls, complaints or investigations recorded about the issue as of Wednesday. The fix at the dealer involves changing out the headrest and seat covers, except for a part of the passenger seat that needs to be calibrated by the factory, according to the bulletin. The C-Class is a critical car for Mercedes as it battles BMW, Lexus and others for supremacy in the ultra-competitive luxury segment. The C-Class, which launched last fall, is moving upmarket as Mercedes reshuffles its lineup with the addition of the CLA sedan. The C-Class was the company's best-selling model in January with volume of 6,236 units.
