Mercedes-AMG GT and C63 to serve as F1 safety, medical cars

Mercedes has spent nearly 20 years providing the safety and medical cars for Formula 1, so it was hardly a shock when the company announced that the new Mercedes-AMG GT and C63 AMG S Estate would serve as ushers in the F1 circus. The two turbocharged monsters replace the old SLS AMG safety car and C63 AMG wagon medical car, which have served in one trim or another since 2010 and 2008, respectively. The biggest change for either car is, of course, the lightbar. It's been mounted atop a carbon-fiber hoop on the AMG GT that Mercedes says optimizes airflow to that big rear wing. Meanwhile, the location of the lights was confirmed via wind tunnel testing. In the cockpit, two iPads allow the AMG GT's passenger, fuel analyst Peter Tibbetts, to monitor the race's world feed while also keeping an eye on race data. The tablets stay connected via an in-car, wireless internet connection. Changes for the C63 S wagon are less extensive. It gets a lightbar and the usual signaling systems in the headlights and taillights, while the cargo compartment includes both a respirator and a defibrillator, to manage more serious medical emergencies. As with the AMG GT, the C63 is finished in F1's traditional silver safety/medical car livery. Beyond these changes, both vehicles are just as potent as those that can be purchased at dealers. Both cars feature a 4.0-liter, 510-horsepower, twin-turbocharged V8, while a seven-speed AMG Speedshift transmission dispatches the grunt with lightning-quick shifts. So equipped, the AMG GT will hit 60 in 3.8 seconds and the C63 can get there in 4.1 seconds. Check out the full gallery of both cars, decked out in their F1 liveries, available up top.

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.

Rare Isdera Imperator 108i flexes its considerable muscles

The Isdera Imperator 108i is a remarkably rare supercar from the late 80s and early 90s. Born of a Mercedes-Benz concept car, it's powered by a range of AMG-developed V8s, with five to six liters of displacement, depending on the engine. The example shown here, lapping the legendary Spa-Francorchamps circuit, features the most potent 6.0-liter V8 available. And rather than just being driven about on a perfectly clean racing line, it's freaking power sliding!
Yes, there's something eternally childlike about a wedge-shaped supercar from our formative years being flung about a Belgian racetrack. Adding to the appeal is the Imperator's stumpy, periscopic rear mirror, sticking out of the roof. Even after being out of production for 20 years, this is still a wild, wild car and we'd happily snap up the opportunity pilot one of the 36 Isderas that were built. Take a look below for the full video from Spa.
