Brabus Mercedes-AMG GT is a 600-hp exercise in restraint

Big, wild, crazy vehicles from local tuners are one of the highlights of all European auto shows, where even high-performance cars get ludicrous amounts of horsepower and questionable body mods. Occasionally, though, one tuning shop comes out with something that is actually pretty reasonable in both departments. At the 2015 Frankfurt Motor Show, that vehicle comes from Brabus and its take on the Mercedes-AMG GT, simply called the Brabus GT. Sure, it has 600 horsepower, which is a lot, but it's only 97 hp more than stock. Asking a European tuner to increase a car's horsepower by just 97 ponies is like asking a six-pack-a-day smoker to quite cold turkey – it requires a tremendous amount of self-control. It's a similar story on the body, where we get a new body kit, new wheels, and a slightly tweaked interior. Now, to be fair, the body kit is made from carbon fiber and the wheels are staggered, multi-spoke alloys, but neither mod is too garish. The cabin gets new black leather, which comes from cows and not some other typical Euro tuner hide, like whale foreskin. The steering wheel gets an Alcantara wrap, and there's some carbon-fiber and wood trim added as well. It's all very, very simple, and not just for a European tuner – we could picture Mercedes itself coming up with a very similar treatment if/when it does an AMG GT Black Series. We've got a wide array of live photos of the new Brabus GT from its Frankfurt debut. Scroll up and check them out. Related Video:

Mercedes giving SL a nose job

Mercedes tends to keep its SL roadster around longer than most models. The previous fifth-generation machine was launched in 2001, underwent a facelift in 2009 and stuck around until 2012. That's when the current model was introduced, and before it's replaced, Benz is expected to roll out another facelifted version. And that seems to be exactly what we're looking at here. Expected to arrive sometime in 2016 as a 2017 model, the updated SL will likely feature revised styling front and rear (along with updated interior equipment). This prototype appears to be wearing headlights from the new S-Class Coupe, which don't fit precisely, but then Daimler still has a couple of years to get everything just right.

Mercedes-AMG could use electric turbos

Mercedes-Benz is joining Audi in analyzing electric turbochargers for its production cars. But while Ingolstadt will roll out its first e-turbo in its A8 luxury sedan, Stuttgart is studying the technology for use in small performance cars, like the A45, CLA45, and GLA45 AMG models. Auto Express spoke to Mercedes-AMG compact car boss Steffen Jastrow about the cutting-edge tech, which reduces turbo lag, improves fuel economy, and occupies less space under the hood than a standard turbo. "Of course we need more power for the next-generation of cars, but electrification does not mean we have to use an electric drivetrain." Jastrow said. "They have to be faster and e-turbos are an option. We use them in motorsport, but the technology has to be payable for the customer." As AE tells it, bringing the price of e-turbos down from the A8's luxury car level to the relatively affordable sums demanded by compact AMG models will still take some time. So don't count on seeing a Mercedes with an electric turbocharger until the new A-Class arrives in 2017, at the earliest. Related Video:
