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 cut fleetwide emissions by 4.3 percent last year

Mercedes-Benz says it reduced its fleetwide vehicle emissions by 4.3 percent last year. Of course, the German automaker has another 29 percent to go to meet the European Commission's 2020 mandate. But who's counting? Mercedes' luxury and sports car bent has made it a relative laggard when it comes to increasing fleetwide fuel-efficiency, but the company did reduce emissions from 140 grams of CO2 per kilometer to 134 last year. The company's fleetwide fuel efficiency (calculated using the lenient European standard) was 5.4 liters per 100 kilometers, which equals about 44 miles per gallon and represents a 25-percent jump since 2007. Benz has come a long way from its gas-swilling V8 tanks of the 1970s. In fact, the company said its top performer, in the fuel-efficiency sense, was the diesel-powered B180 CDI BlueEfficiency Edition, which consumes 3.8 liters per 100 kilometers. That equals about 62 mpg (again, on the lenient scale). The company got some additional good press by revealing that Winfried Kretschmann, Minister-President of the German State of Baden-Wurttemberg, drives a Mercedes-Benz S300 BlueTEC Hybrid. Not exactly a Nissan Leaf, mind you, but it's a start, as is the company's efforts to bring its fleetwide emissions ever closer to the 95g CO2/km level that the EC is mandating by 2020. Take a look at Mercedes-Benz's press release below. Minister-President of the German State of Baden-Wurttemberg, Winfried Kretschmann (left), with Prof. Dr. Thomas Weber (right) and a Mercedes-Benz S-Class S 300 BlueTEC HYBRID Fleet fuel consumption for Mercedes-Benz Cars falls to 134 g CO2/km: Top efficiency figures in all vehicle classes Stuttgart, Apr 08, 2014 Benefit for the environment and customers: In almost all vehicle classes, Mercedes-Benz offers the most efficient vehicle in the competitive lineup. Moreover, in 2013 the company was able to reduce the fuel consumption and CO2 emissions[1] of the Mercedes-Benz Cars EU new vehicle fleet by a further six grams, to 134 g CO2/km. This means that in 2013, the average fleet consumption was 5.4 litres/100 km – a reduction by 24.7 percent since 2007. At present the company offers more than 50 models emitting less than 120 g CO2/km and 71 models emitting less than 130 g CO2/km. Customers can find vehicles in the Mercedes-Benz model range that consume considerably less fuel than competing models. "With our model initiative we want to be the leading premium manufacturer by 2020 again, says Prof.

Mercedes teases a new Maybach concept convertible

Once again, Mercedes is taking a Vision concept to the Pebble Beach Concours this year. To start generating excitement, the company has released a teaser trailer for the car, and effectively no other information. But we think we've pieced together what the car is. Let's look at the video first. It shows a voluptuous blue body. It's all curves and clean lines inside and out. It also has an impressively prodigious prow with a proud three-pointed star at the front. The interior is all white with very little detail, and in addition to chrome, there are many copper trim pieces. There appear to be only two seats, too. Toward the end, we see a strip of copper trim on the outside as well, and just before the shot changes, we can see a bit of white interior that indicates this is a convertible. So we know this is an elegant, luxurious roadster. Is there anything else we can discern? Well, it seems Mercedes may have accidentally revealed the name of the car, or at least what it's based on. The video's file name includes the words "Maybach six." That happens to be the name of last year's Mercedes-Maybach coupe concept. On top of that, there's a striking resemblance between the long, flowing hoods of both cars. So it seems like a pretty safe bet that Mercedes will show the convertible version of that car, which was 18 feet long, and produced 738 horsepower from a quartet of electric motors. We'll find out if we're right when the car is revealed at Pebble Beach.
