The narrative set by the originator of the thread is incomplete. You cant talk about engines without the transmission.

The fundamental fact is engine is merely an untamed horse. Rev it hard as much as you want, its untamed power needs to be worked upon by a capable transmission!. Alone , the engine is an incomplete part of the whole system.

We all know what kind of increase in car speeds one would get on a car which has a CVT as a transmission strapped to it. Step down on the throttle and you know what you get, mere noise, thats all. CVT is good enough with delicate throttle inputs and even then with its 'infinite gears abilities' falls short when it comes to converting high rev band of the engine.

Now lets bring in the conventional AT, the box is timeless and goes a long way however, whether it comes to converting the power of the engine, its sapping nature is the downside. Whether its low, mid or high rev band it will continue to sap the engine power.

Only DCT and MT can do justice to the untamed power of the engine.

The answer is mostly simple - It sounds fun and gives you a psychological sense of speed.

It does not matter what you are driving. I have a humble Honda Aviator with 110 cc engine, a no sporty vehicle, but it redlines at 7000 rpm.



While there is no tachometer, you can sense when the scooter is at its peak rpms. Even with a CVT and a speed limit of 82 km/hr, you will get a rush, perhaps no less than feeling the wind in a convertible sports car. No wonder I see young Activa riders blipping and modulating the throttles once they discover the small engines can touch high rpms.

I have a VAG TDI 1.5 diesel and that thing revvs all the way to 5,500RPM in the way a diesel should not. And surprisingly, it doesn’t looses power in the higher range and sounds very sporty. One weird observation though- the engine feels rough at 2500rpm but once you cross 3000rpm, its becomes smooth. Even at 4k, it doesn’t sounds clattery like a diesel does. I absolutely love pushing the engine around when the road & traffic conditions permit.

I'm curious about this too. The Elevate would make the list too, but do any other mainstream manufacturers offer fun NA cars these days?

Hyundai has a nice 4 cylinder 1.2 petrol, found in the i10, i20, Aura, Venue; but that's a bit underpowered.

In fact, is there any website that let's one filter by kind of engine?

Finally...we have dedicated thread for it clap:

I have a Honda City Gen5, why I bought it: Engine, engine and engine. Though it ticks many other boxes also for me.
My opinion: Petrols are meant to be revved!
Turbo is a necessity in diesel but a convenience in Petrol in terms of torque availability, fuel economy if driven rightly, etc. Choosing a turbo petrol over NA petrol is almost like choosing an automatic over manual :p. High revving engines with manual transmission is the ultimate combination when it comes to enjoying the cars performance, Vehicle Dynamics separate.
Loving reading the comments!

Doesn't the verna have a NA 1.6L engine? Think peak power is at 6300rpm. Sorry if i am wrong.

I didn't even think of ATs. I associate high revving engines with motorcycles as tiny pistons equal higher redline and they're almost always manuals. With cars I don't think even a DCT is that fun. MTs are the way to go. Holding a gear with consistent progress on a curve or an overtake with that adrenaline rushing sound knowing only you get to decide when to go to the next gear. Truly an amazing feeling.

clap:
The i20 nline and lancer redlines till 6500

Apart from the Honda city, the most fun I had was on an Alto K10. It was able to rev till 6000 easily and was so much fun both on hills and highways.

Actually Turbo charging is what killed the high revving engines - petrol and diesel. Turbos run at very high revs 100-160K rpm, so they have a very small boost range. This is what has made manufacturers to restrict the red line in modern turbo charged cars. In the interest of reliability, to avoid risking a blown turbo, the rev limit is imposed.

We love screaming engines, anyone remember the enfield fury revving upto 11,000 RPM or even the Shogun at 9,000 RPM. Much better music that the electric mixie sounds of the F1 cars. rl:

Almost similar except civic which I’m yet to lay hands. What none than the legendary vtec !
Heart still skips a beat if I remember those moments where vtec kicks off ! One was in Blr -mys before the expressway was built. Just imagine now then. Reduced my long drives thanks to back issues.

Started off with zen in 2006 -2013 and 1.5,Baleno Vtec, in that order from 2014-2024.

The revved vtec is like a tiger ready to tame!!
Except for my back issue given a chance the top 1 in my list that I always love to ride is my vtec!! They won’t or anyone won’t built these anymore ! I think you should ride and experience it. !!

More than high revving engines, I like 'free and quick revving' ones. Be it car or motorcycle, engines which don't show any resistance to revv are alway's a pleasure to drive. Maruti K series, G series, Bs6 Maruti F8D, Honda iVTEC engines, Hyundai 1.2 Kappa, Bajaj-KTM engines, Bajaj P220, N250, Apache 200 4v, Apache 160 4v, Yamaha RX100, Suzuki Shogun, etc. are some examples that I can think about.

I just can't sell my Honda City after 10 years of ownership! The feel above 3500 all the way to the limiter is just next level. I don't think anything else can come close south of 30 lacs. Obviously the car itself is built to last like a tank!

My choice is a bit of a compromise - I put my money on a 9th gen civic Si - 2.4l, 7200rpm engine. When it came out it was panned by most 8th gen fans because the K24 traded a bit of the high strung nature of the engine for a bit more driveability, and compared to the K20 it replaced, the redline came down from 8k to 7. Personally I preferred the K24z7 because it had enough torque down low, and you did not have to rev its nuts off. Today the same engine is revered as the last true VTEC engine.

In my opinion, any discussion in this topic needs to bring in VTEC - or similar tech. It is one thing to be able to have an engine you can spin like a turbine, but having power that keeps coming even at the upper reaches, and not have acceleration drop off, along with the eargasm that comes with it once vtec kicks in you - those memes are very accurate!

The previous model did!

The current Verna has a turbo.
