Mercedes CLA45 AMG Racing is ready for a spot on the grid

Mercedes-Benz trotted out its CLA45 AMG-based racer at the 2013 Frankfurt Motor Show. We first showed you the sedan in the deluge of news and reveals that precedes most good auto shows, and were blown away by the car, formally known as the CLA45 AMG Racing Series.
We were strolling by the Mercedes stand, and figured we'd pop in and take a look at the new racer and its carbon-fiber body panels, gutted interior, and race-sourced aero parts. It's a looker, both as a road car and a track weapon. It's not clear what series the CLA45 AMG will qualify for, although it does seem like a shoe-in for the World Touring Car Championship. Let us know what you think of the CLA racer down in the comments. In the meantime, we've got a full gallery of live images up top, along with the stock images that were posted last week on the Mercedes-Benz Facebook page.

2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.

Mercedes-Benz G500 4x4 squares up for production

After showcasing the G500 4x42 in concept form at the Geneva Motor Show this past March, Mercedes has confirmed that it's putting the monster truck into production. The Mercedes G500 4x42 is a more extreme take on the legendary Gelandewagen. It ditches the extra set of wheels from the earlier G63 AMG 6x6, but keeps its wider track and jacked-up suspension, complete with portal axles, 22-inch wheels, 325/55-section tires, and a good foot and a half of ground clearance. It also loses the AMG-spec engine in favor of a 4.0-liter twin-turbo V8 with 422 horsepower, based on the unit in the C63 and AMG GT. The smaller engine (and smaller axle-count) makes its list price a little easier to swallow than the half-million Benz commanded for the 6x6, but it'll still be a rather large pill. Pricing in Germany is listed at ˆ226,100 – equivalent to over $250k at current exchange rates. That makes it the second most expensive version of the G-Class currently available, behind the G65 that retails for ˆ271,915 (~$309k) in Germany and $217,900 in the US. MBUSA tells Autoblog that there are currently no plans for bringing the G500 4x42 to North America. But if it were to ford the Atlantic, it would likely carry a price tag in the neighborhood of $200k for the privilege of riding higher than just about any other commercially available passenger vehicle on the road. Alle Neuheiten der legendaren G-Klasse ab sofort bestellbar: Der Mercedes-Benz G 500 4x42 geht in Serie Stuttgart, Jun 19, 2015 Stuttgart - Outstanding response to the "Extreme-G": the G 500 4x42 show car proved hugely popular with many customers and is set to enter series production. In the superlative-studded history of the G-Class, the G 500 4x42 is the new highlight in the model range. The technical package consists of the all-wheel drive powertrain including portal axles and the new 4-litre V8 engine with twin turbocharging and an output of 310 kW (422 hp). All the other G-Class models have further improved interiors and powertrains, and meet the highest emissions standard Euro 6. The G 350 d, G 500, AMG G 63, AMG G 65 and G 500 4x42 can be ordered with immediate effect. A new addition to the extreme G-Class model family: the AMG G 63 6x6 is gaining a sibling in the form of the G 500 4x42.
