Mercedes spotted testing hardcore AMG GT at the 'Ring

Mercedes has showcased its new AMG GT in both base and S trims, it's rolled out the GT3 racing version and the Formula One safety car. But we're only beginning to see the extent of the variants that the German automaker is expected to spin off of its new sportscar. And here is the latest. Spied undergoing testing at the Nurburgring is what appears to be an even more performance-focused version of the Mercedes-AMG GT. It seems to be packing an upgraded aero kit – complete with front splitter and rear wing – as well as larger rolling stock. You can bet there's an even more potent version underhood of the 4.0-liter twin-turbo V8 that's already producing over 500 hp in the existing model. Whether Affalterbach deems it worthy of the Black Series label or not is another question, but what's clear is that AMG is gunning for the Porsche 911 GT3 with the performance model you see here – however disguised it may be from our prying eyes.

Mercedes fits new C-Class with AMG kit

It's only been a week and a half since Mercedes-Benz revealed the new C-Class, and it'll likely be a while yet before the replacement for the C63 AMG comes along. But if you want to see a preview of what it'll look like, look no further than the AMG aero kit that has just surfaced.
Expected to debut on the new C-Class at the fast-approaching Detroit Auto Show, the AMG Line Exterior Pack adds a new bumpers front and rear, side skirts, dual exhaust tips, mesh grille, aluminum window frames and - most importantly - 18-inch alloys packing upgraded brakes and fitted to a lowered sport suspension. All of which will help any C-Class look the part, even if the engine remains stock.

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.
