People seem to forget these things produce over 500 hp naturally aspirated, how many engines do that? They are not built to last forever, they are built for high performance. Head bolts are a well known weakness/flaw on they first of the model but they are only bolts at the end of the day. Yes, and these bolts can be replaced, not exactly cheap I might add. I think it was the first engine to be designed by AMG and not actual MB; even some 2013 and 2014 have issues. I personally would avoid this motor, especially the early years. The 6.2-liter, naturally-aspirated V-8 (codenamed M156) was the first engine wholly developed and produced by AMG and it's one of our favorites. Tuned to put out over 500 hp with an addicting sound track, it's widely regarded as an engine that can do no wrong. M156 i'm sure of it.

Alusil lasts a whole lot longer than a steel liner and it is not a cheaper manufacturing process. It has much better wear characteristics than steel/iron lined engines. The problem with the NA 63 engine is caused by bad head bolts and cam wear lobe wear. Not defending that engine because they are very prone to failure whereas most MB engines are pretty solid. That is why all industrial engines have those magic Alusil cylinders, as well as aircraft engines. I love it when someone learns me on my life long study and profession. I have to ask how many years of machinist experience do you have as well as industrial engine rebuilding experience? Most liners are iron not steel. Now I will explain why Alusil is cheaper to manufacture. First off if it were to use iron liners they have to be made separate from the aluminum block that is the first expense. Next they have to be placed in the mold that the aluminum block will be cast in, this is the second expense. So there are 2 huge added costs to add a cast in place iron liner. Now with Alusil the whole aluminum casting is made from the stuff all cast at once. So yes it is a cheaper manufacturing process.

The E-Class' unmistakable German presence gets softened considerably this season, massaging out the wrinkles from an overzealous make an effort to give it more masculine character. That's just about all been ironed out, and though the styling changes for that 2018 E-Class are subtle, they make a substantial impact. The front end gets a smoother and much more open bumper, a new hood, and a range of two different grilles. The E-Class' cabin fared better, especially following a recent refashioning, and the fine materials and trims we've arrived at associate with Mercedes are in full impact, as is the solidly constructed feel of the majority of the controls. It takes to expressive use of trim perfectly: the standard vinyl and wood can end up being upgraded to supple leather, aluminum or carbon-look cut. A huge range in drivetrain offerings almost guarantees there's an E-Class for just about any point on the economy/performance curve. Each of the drive trains is new previously three model years.

The basic E350 fuel engine now has direct injection and can make 302 horsepower, while the 4.6-liter twin-turbo V-8 within the E550 throbs with 402 horsepower. At the surface of the gas-powered, a spooled-up E63 AMG performance edition now churns out 550 hp from the 5.5-liter turbo V-8 or in "S" cut, 577 hp. Mercedes' 4Matic all-wheel drive can also be optional on much of the sedan variety (and standard on U.S market E550 sedans), also its standard on the AMG versions this 12 months. Any of these versions accelerates to sixty mph in 7 seconds or less with the AMG versions throttling the pavement into submission into only 4 seconds. Interior space was improved using the latest E-Class redesign, a couple of in years past, with excellent head and leg room for both front and back seats, which can seat as much as five adults comfortably. Wagon models have much more versatility, with fold-down seats, an open freight space, and two temporary-duties, rear-facing third-row chairs.

Wagons also get a new power tailgate. Over the line, build quality is tight, materials selection is mainly excellent, and quietness is strength. The E Class family provides an impressive number of above-and-beyond active safety features, many of these optional to detect driver drowsiness, monitor blind places, control high beams automatically, maintain an arranged following distance, and help keep you inside your lane. And two of the body styles have earned Top Safety Pick status in the IIHS. Key updates to the 2018 E-Class seriously the electronics side, enhancing safety through a range of sensors and algorithms. With new front-mounted stereo camera system allows three-dimensional imaging of road obstacles and traffic at distances as much as 55 yards, with overall system effectiveness extending out to 550 yards. Standard equipment no more includes satellite radio, and a rearview camera is optional about the base models, but Bluetooth and an energy sunroof are standard. Other luxury upgrades consist of voice-controlled navigation; Sirius and HD Radio; the surround-view camera; heated seats; numerous electronic security assists; and adaptive sport seats. The most coveted feature will be a new 1200-watt; 14-speaker Bang & Olufsen sound system with exquisite rendering of sound.
