Infiniti will turn to turbocharged 4- and 6-cylinder engines, hybrids, full electrics

"And another one gone, and another one gone / Another one bites the dust"
Well, it looks as though the recently approved CAFE standards that aim to increase automobile fuel economy to 54.5mpg by 2025 have claimed another victim. Infiniti currently has V8 engine options available in its M luxury sedan, FX crossover, and QX sport utility vehicles, but that likely won't be the case in future iterations of those vehicles.
According to a report by AutoGuide, increasingly stringent fuel economy and emissions regulations mean that V8 engines are no longer on the table for Infiniti vehicles. V8 engines have traditionally been available in luxury vehicles as a symbol of prestige and power, but Infiniti will look to new ways to bring powerful engines to its lineup while still keeping fuel economy in check.
“I don’t think any car that is on Infiniti drawing boards from here onwards we should expect a V8 to be included in that plan,” Johan de Nysschen, Infiniti's global president.
Infiniti's 5.0-liter V8 produces 385hp, its 5.5-liter V8 produces 420hp, and its 5.6-liter V8 (truck-based) produces 400hp.

Infiniti to say good-bye to V8 engines
There are numerous directions that Infiniti can take with the absence of a V8 engine. Automakers like Ford already have twin-turbocharged V6 engines that develop 365hp while still delivering respectable fuel economy. Even Hyundai is rumored to be getting in on the action with a twin-turbocharged 3.3-liter V6 which generates 395hp.
For entry-level and mid-range models will also see a shift in available engines as well. Infiniti's current workhorse engine is the 3.7-liter “VQ” V6, but Nissan is also working on a turbocharged four-cylinder engine to deliver comparable power and vastly improved fuel economy.
Other options for Infiniti include fully electric vehicles (like the LE Concept) and additional hybrid models (we’re hoping that Infiniti delivers a production version of the Emerg-E).
Infiniti isn't the only luxury maker to drop a V8 engine from its lineup. When Lexus redesigned its mid-range GS sedan, it dropped the 4.6-liter V8 engine option and instead launched the vehicle with a 3.5-liter V6 and a 3.5-liter V6/performance hybrid model for those that want the power of a V8.

You'd be amazed in some of the advances of lubrication systems; especially when it comes to synthetic lubrications.

There ARE "liquid engineers" (typically ChemEng or material science grads with either a master's or a Ph.D.) where pretty much all they do is manipulate materials and refinement/production processes in order to get the desired qualities/properties.

Think of the development of Mobil1 and then multiply that by like...a thousand!

If they can prepreg a soldier armor with a CWA detector; I'm pretty sure that they do wonders for friction - especially once the engine gets upto temp. (Low temp is still a pain.)

You also have to remember that the other advances in the engine where it's nearly variable EVERYTHING; any excess parasitic friction losses could probably be compensated for just by fine adjustments of the engine running/operating parameters, especially when onboard computers become more and more powerful, so rather than storing large lookup tables, it can actually do all the calculations and adjustments on the fly.

And the "smoothness" of an engine also has a fair bit to do with HOW you drive (since engine controls are mostly REactive rather than PROactive).

They are typically called tribologists.

One thing to note is the smaller engines reduce part count and can reduce vehicle size. Take Mercedes C series, it is still big enough to fit a large V8 as in the AMG series, but interior space is less than a Honda Civic. Of course the Civic engine bay will not fit anything bigger than a typical 4 cylinder engine, definitely no V8.
