Mercedes’ Inline-Six Tends to make the Rest of Its Impressive New Motors Appear Like Mechanical Plebs


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.

Honda Calls Civic Rivals ‘Square,’ Tends to make Some Ask ‘Where Are the Coupes?’

2016 Honda Civic Coupe

Remember when Each and every. Single. Automobile. Model. came in a two-door version?

Sure, the days of luxurious and lengthy Olds 98 two-doors and Lincoln Town Coupes are extended gone, but it wasn’t lengthy ago that coupe offerings stretched from a single finish of the compact automobile marketplace to the other.

A purchaser was when capable to choose in between the forgettable Ford Escort and equally forgettable but nicer-searching ZX2. You could get the bland Nissan Sentra or the slightly much less bland 200SX. And so on and so forth.

Two door cars that are not committed sportscars or pickups are increasing fewer, particularly at the reduce end of the market place exactly where volume is king. It is gotten so undesirable that we’ve taken to calling four-door SUVs “coupes,” like we’re in some sort of bizarro globe exactly where up is actually down and humans breathe underwater.

At least a single automaker is holding out against the trend.

Honda is organizing a advertising blitz for its 2016 Civic Coupe that functions a industrial titled “Square,” where a sleek Civic two-door rolls past a landscape filled with square individuals, square pets, and square little ones riding square skateboards with square wheels.

The ad aims to draw consideration to the Civic’s rakish flanks and sleek profile at the expense of its competitors, but it might as well be speaking about the vehicle’s door count.

Hunting for another C-segment offering with two doors and no hatchback? Good luck. The preceding-generation Hyundai Elantra presented one particular, but it was dropped. Chevrolet Cruze? Nope. Possibly a Sentra, Concentrate, Mazda3 or Corolla? Try again. Impreza? Get out of right here.

The cheerleaders for low-end coupes are few as automakers scramble to meet insatiable demand for loved ones-oriented crossovers and SUVs.

Range Rover at least gives a two-door version of its sporty Evoque SUV, some thing Mercedes-Benz and BMW clearly see as a bastardization of the classic four-door wagon definition of “coupe.” That said, the only sales success among two-door SUVs in recent years is the Jeep Wrangler.

Cadillac must be commended for wading back into the personal luxury coupe category with its two-door ATS, regardless of what you feel of the brand or the model. It didn’t support general sales, though, as buyers vacated the ATS lineup altogether.

Auto buyers had money, children, house and pets in the ’70s, but bloated luxo-coupes nonetheless sold as fast as wide lapels and Bee Gees tickets. Outside of Germany, it seems customer tastes moved on to other flavors, and automakers had been fast to stick to.

As a former owner of a (beige) two-door 1994 Toyota Camry with gloriously long doors (and, certainly, windows), this writer wonders if coupes are doomed to quantity to an ever-shrinking niche market place populated mostly with higher-end offerings and low-slung rocket sleds.

You’d consider that with crossovers and SUVs parked in every driveway, a family’s second vehicle could stand to be a tiny significantly less utilitarian.

It will be intriguing to watch consumer demand for the Civic Coupe. As an outlier in the automotive landscape, it could serve as a litmus test for other automakers. Who knows, consumers may show they’re not as allergic to two-doors as we believed.

Or, to Honda’s chagrin, they’ll confirm it.
