In changing circumstances of the car market that more and more transitions toward the alternative propulsion methods, it is a bit of a curiosity to see a major manufacturer develop a new V-8 engine. Well, that is precisely what is happening behind the closed doors in the BMW Munich headquarters. There, scientists and engineers work tirelessly to develop a new breed of the V-8 engine. Its name is the S68 (a „logical“ continuation after the current S63), and it will, according to the rumors, keep the „hot vee“ design. This basically means that two turbochargers will remain seated in between the cylinder banks. Something that BMW did first with the N63 in 2008.

I hope, however, that BMW will correct its „oversight“ concerning oil cumulation under those turbochargers, and in between the cylinder banks. I am sure almost every N63, and S63 owner knows what I am talking about.

What Can We Expect From the New BMW V-8 S68 Engine?

If we take a deep dive within the BMW V-8 offering, we can see that the N63 and the S63 make an essential part of the BMW. Every single car more substantial than the 5 Series (5 series included), has it in offer in one way or another. That means that the N63 or the S63 V-8s can fit under the bonnets of the:

  • 5 series
  • 6 series
  • 7 series
  • 8 series
  • X5
  • X6
  • X7

ALL Motorsport versions of these cars feature it too.

The engine develops up to 625 horsepower, and in its least powerful form it churned out 404 horsepower.

FYI, that was for the 2012 BMW 550i F10. For that car, the N63 V-8 managed to return 17 mpg combined and 22 mpg on the highway.Its latest iteration, in the 2018 M550i xDrive with 456 horsepower, it manages to return 19 mpg combined and 25 mpg on the highway.

I am telling you all this so I can prepare you for the future.

See, the next generation of the BMW V-8 twin-turbocharged engine will have to achieve better than what the N63 and the S63 could do. The problem is that rumors do not mention the N68. At all. That can mean one thing – that the V-8 will remain only in the realm of full-fledged M cars. I, obviously, hope that BMW can do better than that. I hope that BMW develops the N68, and S68 V-8 engine for the full range of its future cars. That would mean that the N68 has to achieve at least 22 mpg in the city, and almost 30 mpgs on the highway while churning out more than 450 horsepower.

The S63, on the other hand, has to provide more than 625 horsepower but conform to fantastically harsh emission standards in the developed world.

I cannot see how this can happen without the use of electrical assistance, which leads me to my next conclusion.

If it happens, it is highly probable that the next BMW V-8s – the N68, and the S68 – come with:

  • 4 liter of capacity (achieved by shorter stroke, or smaller-diameter bore)
  • 48-volt electric system with a mild-hybrid system consisting of the 20+ hp starter-alternator unit
  • Cylinder-deactivation system
  • Possibility for the link with even more powerful electric motors
  • Subdued sound by the integration of numerous catalysts and particle filters
  • Lightweight design

I can only imagine that the V-8 equipped with these features can resist the pressing conditions set by regulatory bodies. After all, the Chinese government requires far higher taxation of any car with an engine with more than 4 liters of capacity. BMW wants to beat that for sure.

The word on the Internet is that the new BMW V-8 will make a debut in 2021 at the earliest.

That in the special version of the BMW M5 called the M5 CS. Apparently, the M5 CS will be some sort of lighter, more focused, and far more hardcore version of the M5. It will probably become the fastest, the most capable M5 ever with at least 650 horsepower at that.

Electrified M5?
Possibly!

Conclusion

However you cut it, the S68 (I hope N68 too) are likely the last V-8 engines BMW will ever design. Think about it. The N63 appeared in 2008. BMW still bases its cars around its architecture. If the S68 appears in 2021, BMW could, in one shape or another, keep it alive for 10 more years after that. In fact, Klaus Frölich, the man behind BMW’s research efforts implied earlier this year that the V-8 within the BMW could live for 15 more years. Not without the electric assistance mind you. And this S68 may well be what he was talking about!

Coincidentally, this news comes at the same time when one X7 owner discovered that deep within the X7 infotainment system exists the M60i sign. Some went as far as to say that the X7 could receive a V-12 engine. Now, that could be astonishing if true. Imagine, not even the Urus – a freaking Lambo – has a V-12 in its arsenal. There could not be a better sendoff for the V-12 from the BMW lineup than integrating it in the X7. There’s still time because the same man who implied that V-8 could live 15 more also implied that the V-12 would stick until 2023.
