Why we all will miss "high-revving" engine

So I am the first to say I am and was extremely disapointed when bmw took the turbo route to all M cars and no longer will be the days of RPMS soaring to 8400 or higher. I just don't get how porsche can get 450hp out of a NA flat 6 with less displacement. But that is not the point.

Although there are several things I objectively like about high-revving engines, when I think about it, it actually isn't so clear as to "why" we like it.

Naturally I am not referring to throttle response as that is more of a NA thing and not a high revving thing. Aside from that. Many even say they would have been ok with a turbo v8 revving to 8k but again why?

For me the reasons were straight forward.
1. Probably the most important to me is the sound of the engine and car that you cannot get in any other setup. I really enjoy sound every single drive in this car.
2.the "special" feeling of being somewhat "near" race-car like feel. Nascar actually does not rev much higher than ours. Obviously F1 does but nonetheless it gives you a bit of that "race-car" like feel which makes it feel special each time you drive, atleast for me.

But in the end, while I will miss it, I guess I can't say the important things besides throttle response which seems to be getting better with each engine, will really be negatively effected. Curious other poeples reasons for liking the high-revving nature?

For me it's always been 1) throttle response, 2) high revs. From how the cars feel to me, all the BMW turbo engines still exhibit turbo-lag, despite everyone saying they don't. It's pretty noticeable, at least to me

So why not just keep a few spare S65 M3's for fun? No one says ya gotta move into a turbo.

You must know something the rest of us don't

1) How do you know the new M wont have an equally high redline?
2) How do you know the new M will have the same turbo set up as seen in other BMW platforms?

Its all speculation until the platform is officially released and what does it matter for us anyways, we have the high rev, N/A car

GTR is fast but feels like a Xbox CPU. Not connected enough.

There are engineering advantages (and some disadvantages, of course) to generating horse power at high RPMs, vs. low RPMs.

Consider two engines, both putting out 414HP, one puts it out at 8000RPM, the other at 4000RPM (think big turbo diesel). The first only makes around 250 lb-ft of torque, while the second makes around 546 lb-ft of torque. The drive train strength for the car making 250 ft-lbs is much lower than the needs of the engine producing 546 ft-lbs. This means that the high revving engine can be partnered with a lighter drive train. Additionally, less torque requires(generally) less displacement (or lack of hardware like super/turbo charger), which also saves weight.

Lighter is better for sports cars.

Additionally, there are gearing advantages to high revving engines, the car revving to 8000 RPM can get twice the mechanical advantage (half as tall of gears) as the low revving engine while covering the same speed in each gear.

Lower gearing is better for sports cars.

So if you like light cars that are aided by mechanical advantage, then high revving is for you

The main downside is obviously driveability, which is not a high priority for sports cars.

To determine what is more important to you, consider this.... would you rather drive an NSX to the local grocery store, or a turbo diesel truck cross country?

I will never, ever, ever sell this M3. I might get the new one when it comes out (just because I like to have every new BMW!), but this M3 and my 7 series will never leave my fleet.

Something about a tightly knit small block V8 at 8,700 RPM really makes me smile.

I pulled the trigger on a 2013 for this very reason. The last NA //M motor from BMW. Coming from a turbo N55 engine, nothing compares to the sound and the instant power at hand. The M3 never ceases to impress.

And this surprises you? The GTR is a maniacal speed machine, but as others have pointed out, leaves a very sterile driving experience, especially on the street. I test drove a GTR three times, once for over 2 hours, when I was car shopping in 2011. Still chose the M3. However, if my goal was simply to have the fastest and baddest beast around, the GTR is it, hands down.

Totally... if the engine fails eventually, would buy a new engine in a heartbeat.

A car I tuned that came to me a few weeks ago (which had stock software w/8,400 limit +/- 100) recorded the highest REV I've EVER seen in an M3, 9,114 RPM! I've read the freezeframe data from hundreds of M3's, and never saw anything like that. This is a testament to how well built these motors are considering it's still running fine 20000 miles later.

I would like to see what the S65 could bench RPM at. I have all the confidence it could go over 10K. I know the DCT could not handle that RPM but these motors are just amazing!

I'm not brave enough to try it, but if anyone is I will raise your redline for free!
