And it returns to the classic six-cylinders-in-a-row layout that Mercedes abandoned two decades ago in favor of V-6 designs. While the new inline-six was launched in Europe in the revised-for S-classMercedes sent the United States a fresh twin-turbo V-6 in that car instead. Of course this new straight-six measures 3.
Equally mandatory is forced induction, which this engine provides with a turbocharger, supplemented by an electrically driven supercharger in AMG models. Mercedes has a long history of inline six-cylinder engines dating to But inthe company introduced its first V-6, the degree M, which shared its basic single-overhead-cam, three-valve-per-cylinder, twin-spark-plug design with the subsequent M V The idea was to achieve design commonality between the V-6 and V-8 engines, reducing the cost of manufacturing.
Bythe existing M valve inline-six was phased out. The M evolved into the M ofwith a more conventional single-plug, four-valve combustion chamber. InMercedes introduced the M engine, which shared the bore and stroke of its predecessor but shifted to a degree bank angle to eliminate the need for the balance shaft. By this point, the commonality with the V-8s was much diminished. The new engine, M, goes back to the traditional inline layout with its inherent perfect primary and secondary balance, making it even smoother than a degree V-6—or a V-8, for that matter.
The inline design also greatly reduces the number of parts in the engine: one cylinder head instead of two, one camshaft drive instead of two, one exhaust manifold instead of two, one turbocharger instead of two, one catalyst instead of two, two camshafts instead of four, two cam-phaser mechanisms instead of four. Reducing the number of camshafts and cam drives also reduces friction.
To keep the engine length under control, the M has gone to undersquare bore and stroke dimensions of This contrasts with the The narrower bore allows a reduction in the distance between bore centers from Mercedes has not released the external dimensions of the new engine, but the inline-six block is probably about eight inches longer than the V However, that increase easily packages in the current automotive lineup, without incurring any crash-absorption or other penalties.
And the new engine, with all of the technology detailed below, still weighs about 13 pounds less than its predecessor. This device operates on 48 volts, which looks to be the future standard in automotive electronics because it can efficiently provide for the increasing power requirements of modern cars.
For a given power level, increasing the voltage by a factor of four reduces the current by the same factor, which means that the thickness of the wiring used to carry the power can be reduced, saving cost and weight. This motor can also develop 20 horsepower and lb-ft of torque, so it can provide a useful assist to the engine, particularly at low rpm, reducing the need to downshift when the driver calls for more acceleration.
It can also recover energy during braking to charge its 0. And such a powerful motor can quickly and effortlessly restart the engine during idle-stop mode. In addition to this volt system, there is a separate volt electrical system—with its own small battery—to operate the numerous legacy volt devices on the car.
As volt technology proliferates, expect to see these devices replaced by volt equivalents, which will lead to the extinction of the volt power circuit. To avoid this problem, the AMG version of the M has an electrically driven supercharger to provide boost before the turbo spools up.
This supercharger, which is located downstream of the turbocharger, uses a centrifugal flow compressor—like the compressor side of a turbo—driven by a volt electric motor.The M E32 3. It appeared in The 3. The main differences are the new cylinder block, new The cylinder head is the same as M E30 with four valves per cylinder.
The engine has reliable double-strand chain unlike the single-strand chain on the old M engine. In the engine got variable geometry intake manifold.1994 Mercedes E320 Fuel Filter Replacement

The G-Wagen is characterised by its boxy styling and body-on-frame construction.
It uses three fully locking differentialsone of the few vehicles to have such a feature. Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class inthe G-Class is still in production and is one of the longest produced vehicles in Daimler's history, with a span of 40 years. Only the Unimog surpasses it.
The G-class was developed as a military vehicle from a suggestion by the Shah of Iran at the time a significant Mercedes shareholder to Mercedes  and offered as a civilian version in In this role it is sometimes referred to as the "Wolf".
The Peugeot P4 was a variant made under licence in France with a Peugeot engine. Mercedes-Benz engineers in Stuttgart were in charge of design and testing, while the team in Graz developed the production plans.
The first wooden model was presented to Daimler-Benz management inwith the first drivable prototype beginning various testing including German coalfields, the Sahara Desert, and the Arctic Circle in Construction commenced on a new production facility in Graz, where the new cross-country vehicle would be assembled nearly entirely by hand inwith production of the "G Model" beginning in Graz in Inthe Vatican took delivery of a specially made G-Wagen outfitted with a clear thermoplastic top which served as the Popemobile.
The first major refinements were introduced inincluding an automatic transmission, air conditioning, an auxiliary fuel tank, protective headlamp grilles and a cable winch. Fuel injection became available inwhen the GE was introduced in Turin,  along with more comfortable and supportive front seats, auxiliary heating, wider tires and fender flares. Fordifferential locks, central door locking and a tachometer became standard and by over 50, G Models had been produced.
The G-Wagen was facelifted in Production began the following April.
Fora new sub-series for professional users began production. The civilian model began to offer cruise control, a stainless-steel spare-tire cover, running boards and Burl Walnut wood interior trim.
The same year, the ,th G Model was built in Graz. Inthe model line was officially renamed the G-Class. Ventilated front disc brakes and a driver's air bag became standard. In the automatic transmission became an electronically controlled 5-speed unit. Headlamp washers, cruise control and a front passenger's air bag were added. For a limited run of V 8 powered "G Classic" special editions marked the model's 20th anniversary. A multifunction steering wheel was added to all models. The U.
New alloy wheels, a chrome grille and body-color bumpers plus a more luxurious cabin were introduced. A new version was expected forbut the new GL-Class did not replace the G-Wagen, and it will continue to be hand-built in Graz, Austria at an annual production of 4, to 6, units. W was introduced at a press event held at the off-road proving ground in ToulonFrance. W went on sale in September with three engine choices and five body variants. Over the decade, the engine and transmission choices were expanded or updated along with more and more optional extra cost creature comforts air conditioning, automatic transmission, power windows, etc.
Mercedes-Benz never exported G-Wagen officially to the United States because it was considered more of utilitian vehicle and didn't fit the American perception of what Mercedes-Benz was. During the s, the grey import specialists brought W to the United States and modified them to meet the US regulations. Inthe new federal law, Motor Vehicle Safety Compliance Act, closed the loopholes and tightened up the regulations for grey imports, making it more difficult and more expensive for the registered importers to federalise W in a very small number.
Despite the availability of turbocharged diesel engine in other Mercedes-Benz vehicles, it was never fitted to G-Wagen W The rarest W variants were GE 2. Brabus increased the engine displacement of 2.AMG was originally an independent engineering firm specializing in performance improvements for Mercedes-Benz vehicles. AMG models typically have more aggressive looks, a higher level of performance, better handling, better stability and more extensive use of carbon fibre than their regular Mercedes-Benz counterparts.
AMG variants are usually badged with two numerals, as opposed to regular Mercedes-Benz vehicles, which have three e. Inmost of AMG moved to Affalterbach, with the racing-engine development remaining at the old location in Burgstall.
At this time, Erhard Melcher ceased to be a partner, but he continued to be an employee at the Burgstall location. AMG started off by designing and testing racing engines. It expanded its business into building custom road cars based upon standard Mercedes cars.
During the early s and up untilAMG offered a variety of engine performance packages, alloy wheels and styling products as an entirely independent company from Daimler-Benz. Typical AMG performance enhancements, which the buyer could custom order, included increased engine displacements 5. A Getrag five-speed manual transmission could be ordered from AMG, and Mercedes had not offered a manual transmission V8 since the early s. Penta was actually a UK-based company that supplemented the high demand for the AMG wheel at the time with a replica and only a very slight styling difference, but they were not made or endorsed by AMG.
The genuine AMG wheels were often coupled with an AMG performance suspension package that included uprated and lowered springs, and re-valved shock absorbers.
Another popular cosmetic upgrade were the AMG body kits. These ranged from subtle front spoilers, to an aggressive Wide Body kits for the W coupes. Other options included Recaro seats, smaller diameter steering wheels, instrument clusters, chrome delete option all brightworks colour-coded or painted satin blackrefrigerators, shift knobs, hi-fi stereo systems, custom upholstery and enhanced interior wood packages.
AMG made the world's fastest passenger sedan at the time, nicknamed the Hammer,  by squeezing Mercedes 5. Through the early s, AMG focused principally on supercharged V8 and V6 engines, but the company officially abandoned this technology in with the introduction of the naturally aspirated 6.
ForAMG released the M 5. Although there were some AMG models in the s with manual transmissions, almost all recent models have used automatics 5G-Tronic and later 7G-Tronic with Speedshiftin contrast to BMW Mwhich used manuals and recently semi-automatic transmissions the current type being a dual clutch transmission.
Compared to BMW M, Mercedes-AMG is "less narrow in its sporting focus, yet still combining sledgehammer performance with relaxed handling, cultured comfort, and practicality". While founders Hans Werner Aufrecht and Erhard Melcher had emphasized proper racing cars, Mercedes-AMG had diverged considerably from this philosophy in recent years, with their offerings being well known for straight-line acceleration but poor handling dynamics.
However, current Mercedes-AMG chairman Volker Mornhinweg has urged the division to return to its roots of building sports cars. AMG was made the official partner. AMG also provides engines for the Zonda and Huayra cars. It is the largest displacement naturally aspirated engine provided by AMG and is now exclusively used by Pagani. The technical partnership will support Aston Martin's launch of a new generation of models and newly developed bespoke V8 powertrains.
All AMG engines - with the exception of the "35" M 2.
To signify this, each AMG engine builder stamps the engines they produce with an engraved plaque depicting their signature. As part of the official Mercedes product line, the AMG models are sold side-by-side with regular production models, unlike those offered by other Mercedes tuning firms such as Brabus.
At kW hp and nm in the 45 S variant, the M is the world's most powerful four-cylinder engine in serial production with a specific output of hp per litre or hp per cylinder. With the launch of the 3.
