Mercedes-Benz GLA45 AMG spied in Sweden

We've spotted the all-new Mercedes-Benz GLA testing a couple times in recent months in getting closer to production form and shedding camouflage, but now it looks like we're see our first look at the AMG version of this compact crossover. The low ride height might trick some into thinking that we're just seeing the already-confirmed A45 AMG out testing, but the unique beltline, rear doors and side windows confirm this is some version of the GLA-Class.
What makes us so confident that this is the AMG model? Well, for starters, this prototype has beefier brakes with cross-drilled front and rear rotors and bigger front calipers, but it also sports dual exhaust outlets poking through the rear fascia and a suspension that has been lowered considerably. Our spy shooters said that this car's exhaust note made it almost certainly an AMG model.
Just to be clear, the GLA AMG will not be powered by a 4.5-liter engine. The closely related A45 AMG will carry the "45" in its name to celebrate the first 45 years of AMG, and our sources seem to indicate the AMG version of the GLA will do the same. We're expecting this sporty crossover to produce as much as 350 horsepower from its AMG-tuned four-cylinder engine, and like the all-new E63 AMG, it could very well come standard with 4Matic all-wheel drive.

EVO "2012 Car of the Year: The Track Battles" is a sports car salmagundi

EVO has come out with another gotta-watch-it video, throwing its 2012 Car of the Year contestants around the UK's 1.5-mile Blyton Park track. It's actually a 15-minute teaser for the full-length DVD detailing the magazine's Car of the Year selection, but the tease is worth every penny free second.
Tiff Needell and sports car racer Richard Meaden handle the wheel duties, the two driving five pairs of sports cars: Lotus Exige S vs. Porsche Boxster S, Morgan Three-Wheeler vs. Toyota GT86, BMW M135i vs. Porsche 911, Mercedes-Benz C63 AMG Black Series vs. Alpina B3 GT3, the marquee event pits the McLaren MP4-12C vs. the Pagani Huayra. After a head-to-head lap with commentary during drifts, Meaden takes each car out to set a representative lap time.
You'll find the verdicts, lots of tire smoke, and lines like "Anything you can do sideways I can do sideways" in the video 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.
