Great get, Kiteboy. That's a whopping MPG.

But.....I must say I don't really understand those speed stats very well. I would understand things like 0-60 and quarter-mile times better.
(Wonder why they don't give those.....)

Thanks for the clarification that those are average speeds.
BTW I can't understand why there is such a HUGE difference between the "standing start" and "flying start" numbers for the long distances, unless the acceleration is unusually poor, which would meant that the car spends a large portion of the distance getting up to speed. For example, on the 1-mile, it's 84 mph average for the standing start and 133 mph for the flying start.

I'd like to see 92MPG any day.

Sometimes, I just gotta know for sure...

The car spends all of the 1st mile accelerating. To verify this, I got the Car & Driver acceleration stats (for the TSX) and calculated the distance travelled and average speed:


Spd(mph) Time(s) Dist(ft) Avg.Spd(mph)
30 2.5 55 15.0
40 3.9 126 22.2
50 5.5 231 28.8
60 7.2 368 35.0
70 9.5 586 42.3
80 11.8 838 48.6
90 15.3 1272 57.0
100 19.0 1786 64.4
110 24.4 2613 73.4
120 34.0 4225 85.1


1/4 mile = 1320 ft, 1 mile = 5280 ft.

C&D also lists the top speed of the TSX as 133mph, drag limited (makes sense that it matches the Accord).

So according C&D, the car, after 4225ft, is going 120 mph. If you assume constant acceleration after that (which is very optimistic), the car hits 133 @ 47s, 6626 ft. (more than 1 mile)

Comparing the two tests, the TSX is better off the line than the Accord CDTi, but the latter has better top-end performance.

Average speed is distance / time. I assumed constant accleration between each 10mph segment, using the equations here: http://cmp-o1.ameslab.gov/physics106/lecture5.pdf

OK, great extra stuff, Kite!

So....0-60 is 7.2 (not bad, not bad!) :D
And we can calculate pretty accurately that the 1/4-mile would be just about 15.5 (not bad, not bad!)

BTW the 0-60 is (I think we'd have to say) better than the 1/4-mile, although both are quite fine.

I never realized that any decent-performing car would spend so much time accelerating during that first mile, much less the whole time.

I wouldn't think that would be the case with MOST cars, though, including the TSX.
Anybody know? Any ideas?

Just filled up my car. Prices:

87: 2.31.9
89: 2.36.9
93: 2.41.9

If that's how they wanna be, heck, I'll pay another dime and take 99 octane. :D

Sunoco formulates a "GT-100" 100 octane fuel that's street-legal (and they sell race fuel up to 117 octane that's street-illegal)

http://www.racegas.com/

http://www.racegas.com/qanda.asp

I found a quote for GT-100 in the Houston area of $36.76 for 5 gallons. ($7.35/gal.) 116 octane is $ 49.52 for 5 gallons. ($9.90/gal.) Would guess at least the 116 octane isn't taxed (!) since it's for off-road use.

Well, sounds to me like I got a bargain! :nervous:

Indeed! You're saving a least $7.48/gallon!
