Scross 1.3
100 @ 2500rpm
120 @ 2750rpm.
I'm confidently mentioning exact rpm as it was experienced using cruise control for a good stretch.

Cruze 150PS Manual

I wasnt able to do a fast run and dont see a chance in the near future due to my traffic time driving, but here is what I captured today:
80kmph : 1300
100kmph : 1600

To get a better FE, COASTING is necessary rather than CRUISING

Pardon my ignorance but by coasting,are you referring to taking foot off accelerator and press clutch and allow car to move on its own for some distance,then press 'A' pedal and repeat this cycle ? If this's what coasting means,then I usually never do this.
My driving style points are,
1. Maintain 105 kmph in highways.
2. Maintain 80 kmph in state highways
3. Maintain 60 kmph in smooth district roads
By following this protocol, I rarely get to press 'B' pedal at all.
4. Anticipate gaps and adjust speed by removing foot off 'A' pedal and modulating throttle input (read= avoid applying brakes unless necessary)
5. Accelerate gradually until lag disappears - not to press pedal to metal in lag zone ( in my case up to 1800 RPM).
6. Upshift by 2000 to 2300 RPM.

And as an added advantage ,you get a comfortable jerk free ride and lesser gearshifts mean lesser physical strain on driver's part.

I am by no means a slow driver as I maintain decent timings in all my trips ,maybe take 15-30 min max. more than boy racers for a 350 km trip.

The reason I follow all these are,
A. I love my car and I mean it. I try my best to pamper the engine,GB,tyres and brakes.
B. I never even dream of selling the cars I get even if it crossed 2,00,000 kms since I form a bond with my steed(s) and want them trouble free atleast mechanically.

P.s: our first car - hyundai Santro 1.0L LE ,done 1,93,000 kms in 16 years and still going strong in cousin's hands.
Our second one - optra magnum done 1,10,000 kms in 3.5 years and counting
Our third one - my ride - VW Vento 1.6 tdi - 28,200 kms in 11 months and counting ... &I I intend to cross 2,00,000 in the latter two cars.

New Age XUV, 100 Kph in 6th gear is slightly less than the 2000 rpm mark, And also the sweet spot for the best fuel economy and next to nil engine noise.

Have to check with the jetta since i can't recollect the rpm level when its at 100 kph.

I had to step out and take a short drive for this one (to take a pic)...because I love it every time I see it, the way my (Classic) Fiesta's speedo looks at 80kmph - like everything has just fallen into place, a picture of perfect symmetry on both the dials! Wonder if the positioning was by design or just a coincidence!

An unintended but good side effect: The beauty of it does sometimes keep me mesmerized enough to stick to the legal limits on the Mumbai-Pune expressway!

Attaching a hastily taken pic a few minutes ago @1.30am - iPhone refusing to focus properly, apologies:



Apart from that, the figures are as follows. Nothing to write home about, the old 1.4 Duratorq diesel mill is strictly tuned for efficiency; it's the chassis and the steering/suspension that give me all the kicks when I need 'em!

80kmph @ 2000rpm (exact)
100kmph @ 2500rpm
120kmph @ somewhere around 2750-3000rpm, don't remember exactly.

5th Gear 80kmph at 2200 to 2500rpm depending on load
100kmph at 2500-2700rpm.

The rpm is not dependent on the load. No matter what the load, a kph in a particular gear will always be at the same rpm. The gear ratio is not going to change because of the load.

My Mazda 3 does 100 kph at just below 2000 rpm in 6th gear. It is a naturally aspirated 2.5 petrol.

[model-t]

XUV 500:

1) 80 km/hr in 6th gear : ~1500 rpm
2) 100km/hr in 6th gear : ~1900 rpm
3) 120km/hr in 6th gear : ~2400-2500 rpm

@extreme_torque, Precisely said! Which means that the only way there will be variations in rpm is if the clutch is clutch is slipping continually or if the wheel size has been changed! ...or just discrepancies in the reported figures.

If you are doing lower speed at the same rpm than you used to, there has to be something wrong with the clutch as it may be slipping and not all the engine rpm is being translated into designated speed after reduction by the gearbox.

Irrespective of the load, a car at X rpm in Y gear should always do a constant speed. There may be very slight variation due to load but again for a healthy engine this should not be the case.

IIRC, Jetta's figures are 1600 RPM and 1900 RPM for 100 & 120 kmph.

Nice thread.

Its worth to note that there is an error in the speedo of most vehicles across manufacturers mostly show on the faster side. Tyre upgrades can also add to the error.

I would suggest to mention the GPS speed also while reporting the statistics.

Got delivery of Discovery Sport couple two days back.

At 100, I see tacho hovering around 1500. I'm not sure whether this is good or bad, but I never expected this from a petrol engine.

Cruising speeds and the corresponding rpms of my 2015 Nissan Patrol on highways in Qatar over optimum conditions:

80 kmph - 1250 rpm
100 kmph - 1500 rpm
120 kmph - 1750 rpm

[Catalyst_delhi]

Ford Figo Diesel 1.4 2013 - My car does the below speeds at the rpms

80 kmph -2000 RPM ~ 23 kmpl - Sweet spot for this engine
100 kmph-2500 RPM ~ 19 - 21 kmpl - slightly noisy but pulls really well
120 kmph-3000 RPM ~ Only on Yamuna Expressway, engine noise at this rpm is nice, never checked mileage at this speed. Strangely my old ford Ikon 1.6 used to hit the speeds at the same rpm almost.

[anirudh_85]

Hello from the lower end of the scale! Here are the figures for my 2010 Spark LS -

80 kmph - 2500 RPM (Engine sounds really sweet here)
100 kmph - 3300 RPM
Haven't really done many 120 kmph runs, but if memory serves me right, this comes up around 3800 - 3900 RPM
