Mercedes-AMG GT3 opts for big displacement without a turbo

There was a time when there were numerous categories in sports car racing: GT1, GT2 , GT3... but these days they've all been amalgamated into the latter. That's left a GT3 class packed with competitors and possibly more contentious than ever before. What you see here is Mercedes' new challenger, in official form after being leaked earlier today by the French website Le Point. Replacing the SLS AMG GT3 that won its class (among other races) the Nurburgring 24 Hours in 2013 is the new Mercedes-AMG GT3. Set to be revealed at the Geneva Motor Show, it's the racing version of the new Mercedes-AMG GT, and aside from looking the business, it has the makings of a highly competitive entry. As you can see, it sits closer to the track surface than the road-going version, and packs more extreme aero – including a front splitter you could serve dinner off of, little winglets to deflect the air away from the front tires, deep side sills, a massive rear wing and (though we can't see it presently) what promises to be a very large rear diffuser. It's also got more ventilation to feed the engine and cool the brakes, and a stripped-out cabin with full roll cage and a steering device that's long since evolved beyond resembling an actual "wheel." To save weight, Mercedes has redone many of the panels out of carbon fiber, but one of the most intriguing elements is what you'd find under that woven hood: instead of adapting the 4.0-liter twin-turbo V8 from the road-going GT, AMG has slotted in the larger atmospheric 6.3-liter V8 from the outgoing racer – coupled to a six-speed sequential gearbox. With its new GT3 entry, Mercedes surely hopes to take a slice of the customer racing market that Porsche in particular has developed into a successful and profitable business over the years. Racing fans, however, will be more interested to see how this puppy fares at Le Mans, the Nurburgring, the Blancpain sprint and endurance series, the United SportsCar Championship, the FIA World Endurance Championship and countless national series around the world. It'll have tough competition on its hands, though, from the likes of the Porsche 911 RSR, Audi R8 LMS, Bentley Continental GT3, Ferrari 458 Italia GT3, McLaren 650S GT3, Lamborghini Huracan GT3 and countless others that battle for glory on a racetrack somewhere on any given Sunday. World premiere in Geneva for spectacular AMG racing car All-out attack : the new Mercedes-AMG GT3 Affalterbach.

YouTube's Super Bowl commercial buzz list dominated by automakers [w/videos]

After Sunday's big game, YouTube will be the place to watch every commercial that you missed when you left your seat for an emergency guac refill or, as we say in Cleveland, took the Browns to the Super Bowl. That makes YouTube the nation's water cooler on Monday, and it's got some preliminary stats to share in the lead up to kickoff.
As you know, Super Bowl advertisers, particularly automakers, like to endlessly tease their big budget commercials in the weeks before the game, many times revealing them outright days in advance. Because of this, YouTube can tell us which commercials have been viewed the most so far, and their top five list is all automakers.
Kaley Cuoco appears to have been a good investment for Toyota, as her ad for the RAV4 has garnered the most YouTube views - six million and counting - among Super Bowl commercials so far. Second place goes to Mercedes-Benz, though not its actual Super Bowl commercial, but rather the teaser for it. You know, the one with Kate Upton and the car washing, which is up to 5.6 million views. Third place is Audi's Prom commercial (3.3M views), fourth goes to Volkswagen's slightly controversial Get In, Get Happy ad (3.3M views), and the fifth and final spot is bookended by the teaser video for Kaley Cuoco's commercial (3.2M views). You can watch all five in order below.

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.
