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.

No "V" engine is inherently balanced, which is why the crankshaft is weighted to deal with the issue.

However, I find it funny that you claim V6 are better since they are the absolute worst. There is a fundamental harmonic difference with the two banks of 3 cylinders working on a 4 cycle engine. A V4 (rare) or V8 can accomplish that much better than a V6 can. A V6 will always be the most unstable and unbalanced, which translates into vibration harshness. Smooth V6s accomplish that by adding balance shafts, which rob power. A V8 will provide better NVH, along with better power across all bands, all else equal.

Coupled with your other comments as a whole, you have know idea what you are talking about.

A lot of the "smoothness" people associate with todays engines has to do with liquid filled mounts and sound deadening material around the firewall.

Don't forget new electronically actuated "active" mounts. They do work fairly well, but the idea of mounts that can potentially cause a vacuum leak just annoys me. Even more so than jelly (hydraulic) mounts leaking out. Plus they're even more expensive than even hydraulic mounts and have added electronics, wiring, and PCM control to go with them.

"Fake" automotive components I can no longer joke about: Exhaust fluid, computer-controlled engine mounts. Still OK: Blinker fluid, muffler bearings, winter air (for tires).

V12 is. Think of it as 2 inline six's sharing a crank.
