Mercedes spotted testing updated A45 AMG

Now on the market (or some markets at any rate) for a couple of years already in its current form, Mercedes is preparing a slight refresh for the A-Class. And that means a new A45 AMG performance version, as well. Pictured undergoing testing in Germany, this prototype is hiding some enhancements for the littlest Benz. We're expecting the updates to be rather subtle, but they ought to help the Silver Star hatch keep up with the likes of the BMW 1 Series and Audi A3 in the increasingly competitive premium hatchback market. Best of all, Mercedes is tipped to be preparing an even more powerful A45 AMG S with over 400 horsepower to keep pace with the upcoming Volkswagen Golf R400. Unfortunately the A-Class isn't offered in North America, but we can hope that some of the enhancements (especially in the performance department) are ported over to the CLA-Class sedan and GLA crossover as well.

Mercedes' CEO says Google should study car use, not car building

Google is rapidly throwing its massive weight into many facets of the auto business. Not only does the search behemoth want to take on Uber, offer car insurance quotes and run a specific version of Android on future infotainment systems, but the company is also at least toying with the idea of constructing its own completely autonomous vehicles. Such a powerful corporation entering the industry could frighten some automakers, but Daimler boss Dieter Zetsche isn't worried. The mustachioed executive doesn't believe that Google actually means to become an automaker but is instead just studying how people use cars. "Google and the likes want to get involved, I don't think in the first place to build vehicles," he told analysts, according to Reuters. Zetsche sees future collaboration with the technology giant in a quite nuanced way in that there are some things they can be partners on and other places where the two corporations might be competitors. One area where Zetsche potentially predicts an antagonistic relationship with Google regards data privacy, a concern is becoming a hot topic in the auto industry at the moment. Zetsche foresees the future of safety in Mercedes-Benz vehicles as protecting occupants not just physically but also safeguarding their personal information. "To be able to provide that, we have to keep control, and we can't do that when it is collected by Google," Zetsche said to Reuters.

2015 Mercedes-Benz ML400 Quick Spin

Mercedes-Benz has taken a risk in its quest to downsize its engine range. For 2015, the brand's popular M-Class five-passenger CUV did away with its trusty 4.4-liter, twin-turbocharged V8, and has replaced it with a 3.0-liter, twin-turbocharged V6. It's no surprise that power is down thanks to this move. Outputs of 402 horsepower and 443 pound-feet of torque are replaced by 329 hp and 354 lb-ft, but weight is down significantly as well. The new ML400 is nearly 300 pounds lighter than the 4,982-pound ML550. Will that tradeoff be enough to satisfy a buying public that's embraced falling fuel prices by buying bigger and thirstier vehicles? To find out if the blown V6 is a suitable replacement for the twin-turbo V8, we spent a week at the helm of the all-new ML400. Driving Notes This 3.0-liter, twin-turbocharged V6 is the same engine being offered in the C400 and E400 sedans. Typical of today's turbocharged engines, peak torque is spread lavishly across the rev range, from 1,600 to 4,000 rpm. That's not as generous a spread as the ML550, which offers all its torque between 1,600 and 4,750, but the power on offer is easy to access. Importantly, the new V6 never feels flat-footed or unable to answer our commands. In fact, the ML400 feels even quicker than its six-second sprint to 60 would indicate, although it's not so fast as to challenge the 5.3-second time of the ML550. After a slight and expected bout of turbo lag, the power arrives suddenly and proceeds linearly until just south of the engine's 6,500-rpm redline. The throttle response is soft in Eco mode, as expected, but sharpens up slightly when the fuel-sipping mode is off, where the gas pedal is still easy to modulate. It's a quiet engine, too. Compared to the brawnier exhaust note of the old ML550 or the howling six-cylinder in the BMW X5 xDrive35i, the ML400's note is smooth and refined, befitting of a V6. Its turbocharged nature is instantly noticed, though. Get on the throttle and the 3.0-liter happily hisses its way up the tachometer. But, it's only when you get on the throttle hard that the engine really weighs in. In day-to-day driving and traffic its soundtrack is unobtrusive and relaxed. The EPA rates the ML400's fuel economy at 18-miles-per-gallon city and a 22-mpg on the highway. That's better than the 14 city and 19 highway of the old V8 ML, but it still seems a bit low, especially for the highway figure.
