Your Car(s): Transmission and Axle Ratio?

[Fleet 500]

I am curious about UCP members cars... what type of transmission (manual or automatic) and the axle ratio.

I'll start...

1969 Cadillac Fleetwood Brougham: 3-speed auto, 3.21:1 (orginally 2.94:1)

1976 Cadillac Fleetwood 75 Limousine: 3-speed auto, 3.15:1

1995 Lincoln Town Car Signature: 4-speed auto, 3.08:1

[johnnynumfiv]

2006 VW Jetta GLI: 6-speed Manual, 3.94
2000 GMC Sierra 4x4: 4-speed Automatic, 3.42
1970 MG Midget: 4-speed Manual, 5.38

[Ferrer]

BMW 118d: 6 speed manual, 3.07.

[Revo]

2006 Fiat Punto: 5 speed manual, 3.8:1

[Matra et Alpine]

1978 matra Bagheera, 4 speed, 3.47
1987 Quantum, 5 speed, 3.58
1992 Alpine A610, 5 speed, 3.44
1998 Suzuki Bandit, 5 speed, 3.2 equivalent
2006 RX-8 PZ, 6 speed, 4.44

Not sure about comparison tho' FLeet.
I think it's fine when it's a smilar car and rev range -- ie large V8 and hence a popular statistic for you guys.

But the cars above vary in rev range from the Bag at 5500 and the RX-8 at 9800 and so the final diff ration doesn't help in comparing those along with the actual gear ratios used. Equally some have a wide power band and some ( tuned Bagheera 'X' doesn't come on cam till nearly 4000 revs and has run out of air at 5500. The RX-8 is 2000-9800 usable or 4000-9800 performance

However I've proivded the numbers for you to do with as you wish Cheers.

I just want to see the extremes... the lowest and highest ratios. So far it looks like 3.07 to 5.38.

1999 Saab 9-5 SE, 4 speed automatic, and what do you mean by axle ratio? I only find these stats:

Gear Ratio:
1st - 3.67
2nd - 2.10
3rd - 1.39
4th - 1.00
Reverse - 4.02
Final Drive Ratio - 2.56

Btw,that 5.38 is a short autocross course only gear.

I really have no idea. It runs 1800 revs at 100 kph, which means it could theoryratically do 250 at 4500....which is where the rev limiter comes in.

I have a Motor Trend test of 3 MG's and I actually know where it is.

So here are some quick specs. None of them had super-low gearing, though, like yours.

Motor Trend, Oct., 1971. (I assume they are 1972 models.)

------------------------ MGB-GT---------- MGB--------- MG Midget

Engine------------------ 109-cu-in/1798 cc 109/1798---- 78/1275
Horsepower/torque------- 92/110----------- 92/110------ 62/72
Curb weight------------- 2,360 lbs--------- 2,240 lbs---- 1,635 lbs
Axle ratio---------------- 3.91:1----------- 3.91:1------- 3.73:1
Transmission------------- 4-speed manual-- 4-speed man- 4-speed man
0-60 mph---------------- 12.8 secs-------- 13.1--------- 15.2
1/4 mile------------------ [email protected] mph-- 19.3@74----- [email protected]
Braking, 60-0 mph-------- 133 feet--------- 134 feet----- 134 feet
Fuel mileage-------------- 25-28 mpg------ 25-28 mpg--- 25-30 mpg
Speed in gears @ rpm--
1st---------------------- 28.5@5500 rpm- 28.5@5500--- 29@5500
2nd---------------------- 45@5500------- 45@5500----- 49.5@5500
3rd---------------------- 70@5500------- 70@5500------ 69@5500
4th---------------------- 96.2@5500----- 96.2@5500---- 96.2@5500

Gear Ratio:
1st - 3.67
2nd - 2.10
3rd - 1.39
4th - 1.00
Reverse - 4.02
Final Drive Ratio - 2.56

That would be final drive ratio... axle/final drive ratio in other words.

I believe this gear set was out of some type of delivery truck that was used in England, it used a midget rear flipped upside down.

Ah ok, then my one is really low then? Is that a good thing or bad thing?

Looks like I've created a new extreme :P

Your car seems to be geared like an old American car (it probably has an American transmission). The gear ratios themselves are pretty high but the final drive ratio is on the low side for low-rev cruising in top gear. Johnny or Fleet, did I get that right?

For me:
1998 Ford Escort (Dad's)
5-speed manual
3.85:1 (or 4.1:1?, but I think that is for the ZX2 only)

1996 Toyota Camry (Mom's)
4-speed auto
3.43:1

Yes, his (Roentgen's) car has a low (numerically high) 1st gear and a high (numerically low) final drive. So it all balances out... the low 1st gear helps acceleration and the high final drive keeps revs down when cruising.
