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.

Drive like a prince: Join us for a walk through Monaco's car collection

Small, crowded, and a royal pain in the trunk lid to drive into during rush hour, Monaco sounds like an improbable location for a huge car museum. And yet, this tiny city-state has been closely linked to car culture for over a century. It hosts two major racing events every year, many of its residents would qualify for a frequent shopper card if Rolls-Royce issued one, and Prince Rainier III began assembling a collection of cars in the late 1950s. He opened his collection to the public in 1993 and the museum quickly turned into a popular tourist attraction. The collection continued to grow after his death in April 2005; it moved to a new facility located right on Hercules Port in July 2022. Monaco being Monaco, you'd expect to walk into a room full of the latest, shiniest, and most powerful supercars ever to shred a tire. That's not the case: while there is no shortage of high-horsepower machines, the first cars you see after paying ˆ10 (approximately $11) to get in are pre-war models. In that era, the template for the car as we know it in 2023 hadn't been created, so an eclectic assortment of expensive and dauntingly experimental machines roamed whatever roads were available to them. One is the Leyat Helica, which was built in France in 1921 with a 1.2-liter air-cooled flat-twin sourced from the world of aviation. Fittingly, the two-cylinder spun a massive, plane-like propeller. Government vehicles get a special spot in the museum. They range from a Cadillac Series 6700 with an amusing blend of period-correct French-market yellow headlights and massive fins to a 2011 Lexus LS 600h with a custom-made transparent roof panel that was built by Belgian coachbuilder Carat Duchatelet for Prince Albert II's wedding. Here's where it all gets a little weird: you've got a 1952 Austin FX3, a Ghia-bodied 1959 Fiat 500 Jolly, a 1960 BMW Isetta, and a 1971 Lotus Seven. That has to be someone's idea of a perfect four-car garage.  One of the most significant cars in the collection lurks in the far corner of the main hall, which is located a level below the entrance. At first glance, it's a kitted-out Renault 4CV with auxiliary lights, a racing number on the front end, and a period-correct registration number issued in the Bouches-du-Rhone department of France. It doesn't look all that different than the later, unmodified 4CV parked right next to it. Here's what's special about it: this is one of the small handful of Type 1063 models built by Renault for competition.

Brabus to storm Geneva with 800-hp version of Mercedes SL65 AMG

At no point during our recent drive of the 2013 Mercedes-Benz SL65 AMG did we ever think, "You know, this thing sure is slow." After all, Merc's range-topping SL comes fitted with a twin-turbocharged 6.0-liter V12 capable of sending 621 horsepower and 738 pound-feet of torque to the rear wheels. But just in case you're still all "meh" about what the SL65 throws down, Brabus will gladly come to your rescue with this, the 800 Roadster.
As its name suggests, the 800 Roadster ups the V12's power figures to 800 horsepower and - wait for it - 1,047 pound-feet of torque. Don't get too excited, though - that torque number has been electronically limited to a measly 811 lb-ft since, you know, the transmission would probably explode if you tried to put the full force through it. Nevertheless, these represent increases of 79 hp and 73 lb-ft over the standard SL65, and that means the 800 Roadster can shoot to 62 miles per hour in just 3.7 seconds - two-tenths of a second quicker than the Merc its based on. More impressively, hitting 124 mph takes just under 10 seconds, and the droptop will finally top out at an electronically limited - limited! - 217 mph. Holy smokes.
To manage all of that speed, Brabus has engineered a special carbon fiber aero kit that reduces lift, and a unique control module for the SL65's active body control suspension lowers the ride height by one full inch. The 800 Roadster rides on new 20-inch wheels, and a unique limited-slip rear differential was added, featuring a 40 percent locking rate that further enhances performance when you're attempting to control the beast at its limits. Interior upgrades include new leather and alcantara surfaces throughout the cabin, including a leather-clad trunk.
