Default What's your sweet spot? (RPM)

Hi guys!
I looked and looked, but did not find anything related to this.
See, everyone in my group recently upgraded en-bulk to cars a segment higher.
There is a city, fiesta, sx4, swift and accent inducted, all in the space of the past 10-11 months.
And considering that guys will be guys, everyone had to "test-drive" every vehicle.
Which basically meant ripping it(not literally) on the xpressway/shanti path.

Sweet spot: a particular range in the RPM,where you feel a perceptible kick in the amount of pull the engine is giving, or what i think of as the "happy zone".in techincal terms this would be the "peak" (??).

As i tried all the cars, i was so attuned to the fiesta's sweet spot, that i was trying the same shift on all the other cars, and things werent looking very accelerative.

So here goes:
for the

Ford Fiesta-SXI - 1.6 Petrol.

Shift pattern-
Moderately aggressive
(for own fun's sake only.not red light racing)
1st: 1800
2nd:2500
3rd:4000
4th: 4000
5th: as far as it can go sensibly.

Eco/sedate mode:
1st:1800
2nd:2000
3rd:2000
4th:2500
5th: stable at 2500-3000

My car's sweet spot is apparently, all the way from between

3000-3100 to 3700-3800.

Most bang in this spot is in 3rd gear.
Hardly found that surprising, not by some technical skill, but because i used to get a similar get-up-and-go in 3rd gear in a zen, a santro, an rx100, and a p180.

Whats yours?

Sumo: 2k. In any gear. Each gear behaves in it's typical natural way at this RPM, but 2k is where I love to be.

Ikon: approx 1800 - 1900 rpm in city.

Pottering around in no hurry - 1500-1800 rpm (70% of the time)

Gotta get to work - 1900-2400rpm (20% of the time)

Let's see what she can do - 4000-5500 rpm (10% of the time)

Highways is the band not counted above, between 2500 and 3500 rpm or so for steady speed cruising.

Fiat Linea T-Jet.

1.5 OHC: 3200 - 3500. If i am driving with ac on, then there is a distinct pull that one can detect in this rpm range in 2nd and 3rd gears.

Had a zen earlier but that didnt have a tacho. So, can't really say.

Car - Baleno 2800-3400 rpm.

I think the rpm at which the peak torque is generated is the sweet spot.

This question is of more relevance to Turbo owners. Lets wait some magnum, 1.8Tsi owners to chip in. Our sweet spot will be nothing when compared to their neck braking torque.

However, as an answer to the question, my IKON's sweet spot ie, the pull is in 2.8 - 4.5 k. Above which is pointless, unless I'm timing fastest 0-100kmph. Ah.. and the sound too, is addictive.

Thats different.
Im not asking about when the turbo kicks in.
Those guys will have a different tale to tell.

Maruti Esteem Vxi.

City driving, usually change gears at 2000-2500 RPM. On the highway, 3000RPM seems comfortable.

Still learning, do advice.

For Honda City anything above 4K RPM is pure bliss.
You get the i-VTEC roaring, excellent pick up and nirvana in other words.
But I take her to 4K RPM only on freeways and not in city.

Don't have tacho in WagonR, so have to rely on engine sound for everything.

PS - This thread should be in shifting gears or technical stuff section.

Car -TDCi Figo.

3 rd gear above 1800 rpm is like fun. No other gear matches this fun, the car just takes off. That's my sweetest spot :P

Getz 1.1 - shift between 2.5-3.5K - 90% of the time // shift between 4-5K - 10% of the time.

Padmini - no Rev counter - shift when exhaust note gets orgasmic.

Can understand.
My uni filter magnifies the intake sound in the fiesta's sweet spot, and it...is...AWESOME!

More than the RPM, I love the 3rd gear the best as both my cars feel really agile in this gear.

Cruze : 1800rpm-2500rpm is ideal for any situation including aggressive driving in city conditions in any gear but, 3rd being my favorite. There is no need to go beyond 2.5K rpm as its enough to beat any competitor only until this rpm

In my 15,000kms run, I may have touched 4k RPM only ONCE. Whereas, the redline is at 4.5K RPM

i10 Kappa: Low end torque isn't great and once it crosses approximately 2500rpm and in 3rd gear. It can give a run for money to any sedan. Nimble and quite fast.

Difference between both cars. i10 at 100kmph feels like your going F1 type of speeds whereas, in Cruze 150kmph is like taking a walk in the park.
