Mercedes-AMG GT pressed into service as DTM safety car

DTM is one of the most competitive, fast-paced touring car series in the world. So to set the pace, the marshals need a pretty fast car as well. And that's just what they got with the new Mercedes-AMG GT pictured here. Marking its debut at the Lausitzring speedway this weekend, the AMG GT S safety car is based closely on the road-going model, but like the version that's already in use in Formula One, it's been modified for safety-car duty. That means a low-profile light bar mounted to a carbon-fiber air scoop on the roof – both tested in a wind tunnel – as well as the front splitter and rear wing from the optional Aerodynamics package, and the optional upgraded rolling stock. Inside it's got racing buckets, six-point harnesses, a flat-bottom steering wheel, and special radio equipment. Otherwise it's essentially the same as the road-going model, right down to the 4.0-liter twin-turbo V8 and seven-speed dual clutch transmission. After all, with 510 horsepower on tap, it ought to be able to stay out ahead of the 490-hp touring cars currently competing in DTM. The new safety car replaces the C63 AMG Black Series coupe that Mercedes previously contributed to the effort, and will alternate with the vehicles furnished by rivals Audi and BMW from race to race.

A new Safety Car celebrates its DTM premiere: at the second DTM race at the EuroSpeedway Lausitz (29 to 31 May 2015), the Mercedes-AMG GT S is set to be deployed for the very first time. The new sports car will help to ensure maximum safety on the race track in the world's most popular touring car series. In technical terms, the 375 kW (510 hp) eight-cylinder sports car is for the most part the same as the series production vehicle – just like its counterpart from the FIA Formula 1 World Championship™, the Official Safety Car. In its road-going guise the Mercedes-AMG GT S has turned heads since its market launch in March 2015 and now the sports car is also taking to the DTM stage. The new season of the German Touring Car Masters (DTM) got under way during the first weekend of May in Hockenheim. The second DTM race taking place at the EuroSpeedway Lausitz at the end of May will see the Mercedes-AMG GT S make its first appearance as the official Safety Car.

2015 Mercedes-Benz S65 AMG Coupe

For Mercedes-Benz to truly demonstrate the capabilities and sensations of the S65 AMG Coupe, it needs to commission the building of a highway halfway to the moon. That's right, a ribbon of Autobahn roughly 120,000 miles long, with 50,000 miles of twisties and sweepers. Let's even add some loop-de-loops though the ionosphere, since, you know, we're going all the way with this. We've been following the headlines about progress on a new lunar lander and the SpaceX Mars Colonial Transporter, but we recently discovered that we've already got both of them in the S65 AMG Coupe. This isn't a car, it's a rocket ship. And it's not perfect, but it is spectacular. Starting with the way it looks. When Mercedes unveiled the concept at the 2013 Frankfurt Motor Show, I wasn't impressed. In fact, I told the Mercedes PR person, "It's fine, but the rear end doesn't do anything for me." And today? I'll have the crow, please, with lots of ketchup. When the test car you see here arrived, my loins tumbled and my knees developed a slight tremble. By the following week I was posing thought experiments like, "What's hotter: me in this car, or nothing else ever?" It's big – just eight inches shorter than the S-Class sedan and only an inch narrower. It's an inch longer than the Porsche Panamera and four inches wider, but just 0.3-inches taller than that slinking sport sedan. Its size and segment seem to have freed the designers' pens, and we think it's the best and most unapologetic expression of the brand's current language. We'd normally vote "nay" to a face full of chrome, but the coupe has the width to spread the polished elements around, and the top-to-bottom three-dimensionality indeed earns the adjective "jewel-like." A button on the center console lifts the entire car to protect those jewels when needed. The profile doesn't give up on the rising, sculpted wedge we've known for years – the one we used to love on the SL-Class. And again, the 16.6-foot expanse of sheet metal gives those opposing swage lines an unhurried opportunity to carve the body. The sidelong swell is enhanced by the carbon-fiber rocker panel laid into the concavity along the bottom, as well as those hips over the rear wheels. Speaking of which, the polished, 20-inch forged rollers are spot on. The bluff backside is sculpted just enough to keep it interesting, from the decklid spoiler to the horizontals across the bumper and carbon diffuser. Mostly, though, it seems to say to anyone behind, "Please.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
