Mercedes-Benz is introducing a host of new engines with clever shared modular components, such as a standard 500cc cylinder displacement.
These new engines include a new AMG-developed twin-turbocharged V8 for the S-Class and one of the most encouraging mechanical additions to the automotive landscape seen in a even though — a higher-tech inline-six especially designed to compete with, and outclass, bigger motors.
While Mercedes wants to maintain you interested with claims of vastly enhanced economy across platforms, enhanced efficiency is certainly not the most impressive bit of engineering on offer. For example, the aforementioned inline six-cylinder features 48-volt systematic electrification, so there’s no belt drive for ancillary elements at the front of the engine. This reduces the overall length of what would typically be a pretty long motor and frees it up for packaging in regions that may have not worked otherwise.
Those 48 volts also work with the engine’s electric turbocharger. Mercedes claims that it only takes the e-turbo .three second to attain 70,000 rpm, followed by the bigger twin-scroll exhaust-driven turbo. The intended result is seamless linear power delivery with out any turbo lag. The new inline-six is rated by the organization to “at least” 408 horsepower and 369 lb-ft of torque and Mercedes says it’ll come in silky smooth with 15 percent greater CO2 emissions than the current V6 getting presented.
The other spec sheet darling is the slightly reduced tech M176 twin-turbo four.-liter V8. Though, on paper, this engine appears really related to the four. biturbo that Mercedes-Benz is already generating, right down to the matching 17 pounds per square inch of increase stress.
Mercedes says this V8 will output over 476 hp and 516 lb-ft in the upcoming 2017 S-Class with a ten % improvement in economy — partly due to cylinder deactivation. However, cylinder shutoff is only active in an engine-speed range of 900 to 3,250 rpm and only when the automobile operator has chosen 1 of two conservative driving modes. Otherwise, it’s a complete-time V8.
In addition to two diesel engines that are somewhat much less probably to show up in North America, Benz is also offering a sensible two.-liter turbo 4 for subsequent year’s much more financial models. The package contains twin-scroll turbochargers that merge the exhaust gas ducts of cylinder pairs into a “flow-optimized” manifold. Mercedes says this setup aids in the production of low-rpm torque. The engine also has a belt-driven 48-volt starter-alternator that is accountable for for fuel-saving hybrid functions such as energy recovery, imperceptible on/off at stops, and boosting the engine-speed range up to 2,500 rpm.
