The electronics reduce the engine speed to idle level, and the driving resistance is reduced by the compression and frictional forces of the engine in overrun mode. If required, the driver can also switch it off while in "C" mode as well. This system is standard equipment on the Mercedes-Benz SLK55 AMG and active in the fuel economy transmission mode "C". The 2012 SLK55 AMG complies with the current Euro-5 emission standard, as well as meeting all the requirements of the US market (LEV-III standard, On- Board Diagnosis II). The new Mercedes-Benz SLK55 AMG is able to offer both. A framed "ECO" symbol in the AMG main menu shows the driver that the Controlled Efficiency stop/start function is active. The automatic rev-matching function when downshifting as well as the brief, precisely defined interruption of ignition and injection when upshifting under full load shorten shift times and increase emotional appeal. Other changes include a new grille, 16- and 17-inch rims, improved interior materials, and a nine-speed gearbox to replace the seven-speed automatic. The seven-speed automatic is the only gearbox on the market with the V6.
Aside from their new nine-speed automatic transmission shared with the GLS450, the ’17 GLS350d and GLS550 aren’t expected to perform much differently. We didn’t expect too much from this open-diff machine on steep, loose sandstone climbs, but we were soon amazed by the agility of this big box on our off-road course. Unfortunately, this biodegradable insulation deteriorated much quicker than it was anticipated due to moisture and heat in the engine compartment. An alternator management system makes a further contribution to fuel economy: whenever the V8 engine is in overrun or when braking, kinetic energy is used to charge the battery rather than wasted as heat. Powering those motors is a lithium-ion battery sourced from Deutsche Accumotive, a battery company owned by Mercedes’ parent company Daimler. The company owns a Mercedes-Benz driving academy, where it educates teen drives for public safety. It’s found by Mr. Karl Benz who established the company in 1871 then Mr.Gottlieb Daimler, Mr. Wilhelm May Bach where involved on establishing the division of Mercedes Benz. The main focus of the sound design was to achieve a perfect synthesis of perceptible performance and the long-distance comfort that is a hallmark of Mercedes. The camshafts are driven by three high-performance silent chains, which have considerable advantages in terms of noise comfort compared with cylinder roller chains.
A double turbine torsional damper with centrifugal pendulum adapts to engine speed and helps minimize vibrations in four-cylinder operation as well as enhances comfort. At low loads and engine speeds below 2,000 rpm the flaps remain closed. When the driver accelerates, the flaps open at an angle of 15, then 30 and up to 50 degrees so that some of the exhaust gases cover a short distance while the remaining follow the longer, acoustically dampened path producing a sonorous engine note. Under full load at higher engine speeds in eight-cylinder mode, both flaps are fully opened so that the occupants are able to enjoy the distinct muscular sound typical of an AMG V8. Get into the cockpit and there are few steps before you can fire up the engine. If required, the Mercedes-Benz Sprinter Mobility can be tailored to fulfil a host of applications. The efficiency of the Mercedes-Benz Sprinter Van begins with its cabin.
For efficiency and to save space, this design has a tandem catalytic converter housing on each side of the vehicle: adjacent to the firewall, two thin-walled ceramic substrates are grouped into each housing. The Controlled Efficiency stop/start function further contributes to the low fuel consumption. In the two more performance-oriented driving modes "S" (Sport) and "M" (Manual), the stop/start function is always deactivated. Similar in design and function to the system used on the Z06, the dual-mode exhaust uses vacuum-actuated outlet valves, which control engine noise during low-load operation, but open for maximum performance during high-load operation. Low exhaust emissions, compliance with country-specific standards and a characteristic engine sound - the requirements for the exhaust system of the new, naturally aspirated AMG 5.5-liter V8 engine were multiple and complex. The crankcase of the new AMG 5.5-liter V8 engine features a diecast allaluminum construction. As honing would no longer be possible with the cylinder head installed, a jig resembling spectacles is bolted to the crankcase.
