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 G 500 4x4 is mighty mean and bright lime green

The Mercedes-Benz G500 4x42, finally ready to meet the crowds at the Geneva Motor Show, might just be the best factory-prepped expedition off-roader on the market, should Mercedes choose to build it. The short story is that some well-heeled admirers of the G63 AMG 6x6 said, "It's nice, but can you take it down a notch?" And by "notch" they meant "an axle." So the G500 4x42 gets just two portal axles instead of three, and a slew of other features. The 4x4 squared offers up a standard G-wagen body, but instead of the 5.5-liter twin-turbo V8 from the G63, there's a new 4.0-liter twin-turbo V8 with 422 horsepower and 450 pound-feet of torque. Compared to the standard G500, the track is 11.8 inches wider, the street-cred rims being 22-inchers on 325/55 R-series tires. When it's time to get dirty, they can be swapped for an optional set of 18-inch wheels with 37-inch beadlock tires. With that setup and the same wheelbase as the G500 LWB, ground clearance and fording depth are more than doubled to 17.7 inches and 39 inches respectively, the angle of approach goes from 36 degrees to 52 degrees and the angle of departure leaps from 27 degrees to 54 degrees. Breakover angle is bumped from 21 degrees to 47 degrees, a two-piece stainless steel undertray protecting the sensitive bits when you push it. The only parts that get a raised eyebrow are the carbon fiber wheel arches and bumpers, which might behave badly when they meet an immovable granite object. To escape the sensation of driving the Taj Mahal in urban environments, there's a twin spring-and-damper setup at each wheel. One of the spring-damper combos is electronically controlled and adjustable, and when called into action via the Comfort or Sport mode, takes control of wheel action; even when passive, it will kick in to automatically to stiffen the body if it detects evasive maneuvers. On top of all that, to remind you that you're in a Mercedes the interior is fitted out with Designo leather trim and diamond-quilted microfiber. Mercedes is going to gauge its Geneva reception before deciding to build it, a hurdle we're sure will be overcome. Car and Driver drove it and verified it's the real deal, with pricing - if it's built - speculated to land between the G63 AMG and G65 AMG. The press release below has all the details.

2016 Mercedes-Benz Metris hits US in October, priced from $28,950*

A Mercedes is hardly what we'd call a budget proposition for most, but everything being relative, what's the cheapest Mercedes you can buy in America? That used to be the C-Class, but not at the $40k it's pushing these days. The CLA or GLA start at over $31k, so one of those must be it... right? Keep trying. And the Smart Fortwo doesn't count. No, the most cost-effective Mercedes you can get in America is the one you're looking at here. It's the new Metris van, and it starts at just $28,950 (*plus a $995 destination fee). Joining the Sprinter (which starts at upwards of $35k), the Metris is Benz's new midsize van – filling a niche in between small vans like the Nissan NV200 or Ford Transit Connect and fullsize ones like the aforementioned Sprinter. It's about as long as the Dodge Caravan-based Ram C/V, but narrower, taller and with significantly more payload and cargo space. Mercedes calls it "right-sized," and evidently hopes commercial drivers and fleet operators will agree. Now if you've never heard the name Metris, you were probably distracted by all the glitz and glamor when Mercedes presented four of them at the SEMA show late last year. But that's alright, because it's a new nameplate: it's essentially the same as the Vito sold overseas, where it will continue carrying that same name, while being sold in North America as the Metris. Both cargo and passenger versions will be offered, the latter starting at $32,500 (plus that $995 destination fee). Power comes from a four-cylinder gasoline engine driving 208 horsepower and 258 pound-feet of torque to the rear wheels through a seven-speed automatic transmission. It's also got all the electronic bells and whistles you'd expect from a Mercedes, including fuel-efficiency and safety equipment – but stopping short, of course, of the luxury features. This is not that kind of Mercedes, and the luxed-up V-Class version offered overseas won't be making it Stateside. The Metris is being showcased this week at the NTEA work truck show in Indianapolis, with deliveries set to commence this coming October through a network of over 200 Mercedes van dealers across America, who will offer it alongside the larger Sprinter.
