View Full Version : How many revs at 60mph
I thought I'd have a look at how many revs my FRV does at 60mph, so I did it this morning and it was 1875.
I was wondering how this compared with everyone else's after the discussion on the 2012 Honda Fit which was 2850!
Blackbelt 09052011, 11:20 AM My Kizashi is around 1700 at 60, :)
seftonm 09052011, 11:42 AM 1600 in the Golf TDI
Right Lane Cruiser 09052011, 12:05 PM 2600 or so in the Elantra, 2000 in the Insight.
alvaro84 09052011, 12:20 PM ~3860 with a BMW F650CS in 5th (4000 at 100km/h). Could use a sixth gear on the freeway, but I rarely go there now.
~6760 with a Hyosung GV250 (7000 at 100km/h). Being chain driven it's easier to make the gears taller. It may happen in the future.
basjoos 09052011, 01:09 PM 1935rpm @ 60mph (2K @ 100kmh) in my 92 Honda Civic CX.
lxmike 09052011, 04:01 PM I'm not sure cause i haven't been over 50 in my insight. i'm probably a lil lower than sean because i have a slightly taller tire.
SentraSER 09052011, 06:01 PM ~2100 rpm @ 60 mph in my 2002 Nissan Sentra SER Spec V (6MT)
~2200 rpm @ 60 mph in my wife's 2006 Hyundai Elantra (4 AT)
~3200 rpm @ 60 mph in my 2006 Scion xB (5 MT) with OEM tires
~3000 rpm @ 60 mph in my 2006 Scion xB (5 MT) with 5.3% taller tires
PaleMelanesian 09052011, 09:47 PM I'm at about 2600 in my Civic. It works for my 55mpgandunder commute but it's horrible on the highway.
some_other_dave 09052011, 11:41 PM 1990 CRX Si: 3000 RPM @ 60 MPH
2011 MINI Cooper: 2400 RPM @ 60 MPH
2011 MINI Cooper S: 2400 RPM @ 60 MPH
2012 Fiat 500: 2400 RPM @ 60 MPH
The last three I have driven recently.

fuzzy 09062011, 02:46 AM At 60 mph:
2500 rpm in 1986 Honda Accord (5MT, 2.0L)
2700 rpm in 1997 Subaru Legacy GT (5MT, 2.5L)
~3000 rpm in 1989 Acura Integra (5MT, 1.6L)
The last two are still in the household stable. The Honda left when the Prius was acquired.
Wow some big differences there, especially the bikes!
JusBringIt 09062011, 12:47 PM 160 hp (factory rating) 1999 Avenger V6: 2100rpms at 60mph
140 hp (factory rating) 1997 Mitsubishi Eclipse GS I4: 2500rpms at 55mph. Not sure what it is at 60mph, however, it goes up 50 rpms for every mph increase (1500rpms at 35mph). That equates to:
2750/too many rpms at 60mph
Die2self 09062011, 02:17 PM 2850 @ 60 MPH for the 2011 MT Honda Fit
alvaro84 09062011, 03:12 PM Wow some big differences there, especially the bikes!
These bikes are different enough themselves: a 650cc single and a 250cc Vtwin.

The VW Golf TDi seems to be the lowest so far at 1600. But low doesn't always seem to correlate with high mpg  just look at Andrew's 2600, that's the same as my OH's Honda Jazz/Fit 1.2 :eek: :D
I've just read that the 1.2 (1246cc) engine has a taller fifth gear than the same year 1.4 (1339cc) and only 6bhp less!

Read Andrew's comment and you'll see that he wouldn't be getting his great mileage if he were driving at 60mph. ;)
PaleMelanesian 09082011, 09:57 AM That's right. A highway trip with speeds above 50 mph drops my mpg from mid80's to mid70's.
I try not go above 55mph in the Jazz/Fit so I think I'll try 50 as a max. At some point will check it with the UG  cheers :D
PaleMelanesian 09082011, 10:25 AM I generally try to avoid going over ~2200 rpm. That's only 53 mph, so any highway trip forces me to rev too high.
You know you're a hypermiler when... you discuss highway speed in rpm and not mph.
ItsNotAboutTheMoney 09082011, 10:58 AM That's right. A highway trip with upper speeds above 50 mph drops my mpg from mid80's to mid70's.
FYP. ;)
PaleMelanesian 09082011, 11:01 AM True. I'm talking about 4560 p&g cycles.
Patman 09172011, 11:45 PM Around 2000 rpm in my automatic Civic and 1700 rpm in my automatic Corvette (it has the optional 3.15 rear axle, up from 2.73 which would only rev at around 1500 and the 6 speed manual cars rev at only 1300!)
The Doctor 09302011, 11:28 AM 60mph? I dunno, because I seldom drive that slow.
But I can tell you that at 80mph, my engine is turning about 3k.
Just for reference:

Admittedly, this isn't the best way to get the best mpg.;)
:cool:
Hi The Doctor:
Maybe you need to practice a bit more of this instead?
2011 Hyundai Sonata Hybrid

EV Mode at 88 mph...
The HSH wasn't using any fuel at the time unlike the VW? Is it a VW as the gauges look VW's?

some_other_dave 09302011, 06:23 PM Doc, you've got 4,000 RPM at 100 MPH. 60 MPH would be 0.6 * 4000, which is 2400 RPM. Easy as pie!
That seems to be a common RPM for fourcylinder FWD cars in top gear at 60 MPH these days.
soD
The Doctor 09302011, 08:29 PM Probably, but my SX4 is a 4X4, not a 2WD car.
I go where Jeeps and monster trucks fear to tread and I do it in style and comfort.:rolleyes::):)
Cheers Mates!
:cool:

DougC71 10122011, 12:09 PM 2012 Ford Focus SE 5spd; just shy of 2500 RPM @ 60 MPH.
EvlMinion 10312011, 09:26 PM About 2950 rpm at 60 MPH  '06 Acura RSX Type S
Rackster 11032011, 08:42 PM My Ranger doesn't have a tach, but once I get an SG, I'll edit this and post the data. I believe that my '04 Accord is at 2300@60 mph, but I'll need to confirm this. My S2000 is at 3400@60 and 3500@65.
FSUspectra 11032011, 09:40 PM 05 Kia Spectra 5 speed, 2860 @ 60 mph
seftonm 11032011, 10:10 PM 6M trans in my Golf. I may have the highest rpm at 60mph too if you're handing out prizes :p ~7500 for the CBR125R 6M.
FXSTi 11032011, 10:27 PM from the Clean MPG Fiesta Review 2011 Ford Fiesta SES 5m 2700 rpm @ 60. I wonder what the 2012 sport package with the 4.25 final drive is at.
RedylC94 11042011, 02:00 AM Approximate revolutions per mile at ANY SPEED in top gear for some cars I've had:
1954, Chevrolet, [std.], OneFifty, 3MT, 3000, (3.70 overall);
1972, Subaru, DL, DL, 4MT, 3700, (4.02 overall);
1981, Mazda, GLC, Custom L, 5MT, 2600, (2.82 overall) .
All above are based on actual gear ratios and tire sizes, not from comparing a tachometer to a speedometer.
PaleMelanesian 11042011, 03:20 PM revolutions per mile at ANY SPEED in top gear
revs per mile = rpm @ 60 ;)

I'd appreciate the missing details for anything that doesn't have it. Either post or PM me. If you just post a brief correction message I'll delete your post after I've updated the table so the thread won't be cluttered. Mod's privs. ;) If you post with other, more detailed information I shan't delete your post.
Rackster 11062011, 07:47 PM A fellow enthusiast pointed me towards this site for calculating RPMs at 5MPH intervals. You'll need to put in data about your vehicle, but it produces data for each of the gears in your ride.

Good luck!

That's easy to calculate for any speed yourself, if you know the relevant gear ratios of your car, and the number of revolutions the tires make per mile. If you don't know that, it can be computed from the distance they travel per revolution, if you know or measure that instead.
The basic formula is
Engine RPM = (overall gear ratio)×(tire revs per mile)×(speed in mph)/(60 minutes per hour).
For most cars (Some are more complicated.) with fixed ratios,
overall ratio = transmission ratio in the gear in question, times the finaldrive (differential) ratio.
For example, for my car, in 5th gear:
5th gear ratio = 30/41 = 0.7317;
Finaldrive ratio = 77/20 = 3.850;
Tires travel about 69 inches per revolution.
Therefore, my overall ratio is 3.85×0.7317=2.817, and
(63,360 inches per mile)/(69 inches per tire rev)=918 revs/mile.
Thus, at 52 mph,
2.817×918×52/60=2241 RPM.

Sure...if you have the time, you can grind out the math with pen and paper or create your own Excel spreadsheet with formulas. It's up to you. A nice feature of the tool for me is that you can substitute variables, for example, if you were thinking about running different sized tires (the impact of going bigger or smaller). For me, where the formulas weren't in mind, the tool made it easier.

EvlMinion 11092011, 04:55 PM I saw 60 mph on the SG at 2410 rpm.
The speedo had a discrepancy, though. 60 on the speedo was 2350. I will put my GPS in the car and see which one's correct.
It's Blue Green listed in the mileage thing below.
