Mercedes-Benz recalls 3,800 total vehicles in two campaigns

Mercedes-Benz is recalling 3,813 vehicles in two campaigns in the US, and the affected models span the top and bottom of the brand's product range. The larger recall covers 2,956 examples of the 2014 S63 AMG sedan and 2015-2016 S63 AMG 4Matic sedan and coupe. According to the National Highway Traffic Safety Administration, a software error in the engine control unit can cause the high-performance luxury cars to stall when coasting to a stop. While this can initially appear to be normal operation of the stop/start system, the engine doesn't restart when the driver releases the brake pedal. Getting moving again involves shifting into neutral or park and going through the ignition process. The repair campaign will begin on December 8, and the models will need an update to the engine control unit software. This will also be the second recent recall for the 2015 S63 AMG 4Matic Coupe because another fix will replace their seatbelts. In a more complicated issue, Mercedes is recalling 857 examples of the 2015 CLA250, CLA250 4Matic, GLA250, GLA250 4Matic, and the 2016 SLK300 because a weld on the camshafts might be in the wrong place "due to a production deviation at a supplier." Potentially, the important parts could break and damage the engine. Beginning November 30, dealers will replace the affected camshafts as a precautionary measure. RECALL Subject : Engine Stall due to Engine Control Unit Software Report Receipt Date: OCT 14, 2015 NHTSA Campaign Number: 15V652000 Component(s): ELECTRICAL SYSTEM , FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 2,956 All Products Associated with this Recall Vehicle Make Model Model Year(s) MERCEDES BENZ S63 AMG 2014 MERCEDES BENZ S63 AMG 4MATIC 2015-2016 Details Manufacturer: Mercedes-Benz USA, LLC. SUMMARY: Mercedes-Benz USA LLC (Mercedes-Benz) is recalling certain model year 2014 S63 AMG sedans and 2015-2016 S63 AMG 4Matic sedans and coupes manufactured May 14, 2013, to September 18, 2015. In the affected vehicles, due to a software error within the engine control unit, the vehicle may stall when coasting to a stop, such as at a traffic light. CONSEQUENCE: The vehicle stall may be interpreted by the driver to be a planned shut-down as part of the ECO-Start-function. However, the engine will not restart automatically after releasing the brake pedal, immobilizing the vehicle and increasing the risk of a crash.

Mercedes unveils GLC350e 4Matic PHEV

Mercedes-Benz intends to introduce at least 10 plug-in hybrid models to the market by 2017, and the the Mercedes GLC350e 4Matic is the latest one to show its electrified face. It's also the second crossover from the company to offer a PHEV version following the GLE550e 4Matic. Mercedes isn't releasing all of the details about the plug-in GLC yet, but it combines an internal combustion engine making 208 horsepower and a 114 hp electric motor with a seven-speed gearbox. Total torque is 413 pound-feet. The combo is enough to get the all-wheel drive crossover to 62 miles per hour in a purported 5.9 seconds and a claimed top speed of 146 mph. Fuel economy in the European cycle is estimated at the equivalent of about 90 miles per gallon, and there's a 21-mile pure electric range for zero-emissions cruising. Based around the newly introduced GLC-Class, buyers can still order a plethora of luxurious amenities, but the plug-in powertrain also comes with a few tweaks to help drivers maximize fuel economy. There's a haptic accelerator with a resistance point to indicate the switch between electric and combustion power. In addition, the hybrid system can anticipate the road ahead through radar and GPS to manage things as efficiently as possible. One of the GLC hybrid's biggest advantages when it arrives is the small field of competitors. Neither BMW nor Audi currently have a compact luxury crossover of this size with a hybrid option in the US. That really only leaves the Mercedes to take on the Lexus NX300h with total system output of 194 hp, and that's not even a plug-in. The GLC350e 4Matic isn't part of the new model's initial launch lineup in the US. It should be coming along later, though. Key topic: Energy efficiency - Economy on four wheels A revised all-wheel-drive powertrain, the outstanding aerodynamics and the intelligent lightweight design are the primary reasons for the high energy efficiency of all the new GLC models. The conventional diesel and petrol models boast significant reductions of up to 19 percent in both fuel consumption and CO2 emissions in comparison to the previous generation, while at the same time improving performance.

Buy a V8 Mercedes-Maybach, or splurge for a V12? Oh to have such problems

There's a certain air that surrounds the Maybach badge, and it's not just the scent being pumped out by the ionizer in the car's glovebox. It's the cream of the crop when it comes to German luxury. These cars are filled with an acre's worth of wood and a herd's worth of cows, ensuring your fingers rarely touch materials as pedestrian as plastic. It's as quiet, as smooth, and as imposing as you think it would be. Though the latest model from Mercedes-Maybach, the S550, might have swapped in a V8 and all-wheel drive in place of the V12 at the heart of the S600, no other amenities have been lost in translation. The car's size gives it a certain presence. Staring at the profile shows a wheelbase that spans two counties, necessitating a microphone and speaker setup simply so that the driver can converse with the passenger – and a Maybach will almost always have a passenger. No one buys a Maybach to drive. You buy a Maybach to be driven. No means of transport short of business-class airline seating offers this much space. Sit back, recline the seat, roll up the shades and enjoy your $167,125 cocoon. But you know all of that already. What you really want to know is if $25,000 - the V12-powered S600 starts at $192,225 - is worth it to gain an extra four cylinders, 74 horsepower, and 96 lb-ft of torque. On paper, no, it's not. The two cars have identical performance numbers, and the S550 benefits from Mercedes' 4Matic all-wheel-drive system. Even with all-wheel drive, the S550 weighs less than the nose-heavy S600. Fuel economy is, as expected, superior in the S550. It's rated at 16 city, 24 highway and 19 combined as opposed to 13 city, 21 highway, and 16 combined. Visually, the two cars are identical save for a few badges. The V12 badge on the S600 is replaced with a 4Matic badge on the S550, and that's where things start to get murky. When you're spending six figures on a car, decisions become more emotional than practical. $25,000 is a lot of money, but there's a bigger difference between $25,000 and $50,000 than there is between $167,000 and $192,000. As stated, you don't buy these cars to drive. Performance needs to be merely adequate. A smooth, torquey V12 is likely preferable to a hairy-chested V8, refined as it may be. These cars will never touch redline, lest the passengers spill their champagne. Plus, that V12 badge is worth its weight in country club memberships. Driving an S550 is fine until an owner shows up at an event behind an S600.
