Still think its potentially slower?
The issue is you stated some 2nd grade level math or peak HP to weight. Some 1960's car magazine crap. The real math involves the average g-force that can be pulled in the car via each gear and the RPM range of the gear untill the desired MPH is reached. Which is why the Civic with a good amount less peak power/pounds ratio is able to keep right with the more peak power car. Had the r18 came with just 5 more hp it would still have less power/pounds ration and be quicker. Or if the r18 had tighter gears.
No Honda is not god of cars. I actully like German cars! Sold my 340ft/lbs VW TDI for the r18, so I am fully aware the naturally aspirated r18 has little torque. Had I not known that fuel prices would have been so high I would have bought a used c43 or a near near GTI.

The math I used is very basic yes, it assumes many more variables than of the equations you've stated above. Still, you've stated no real mathematical calculations, rather pasted images from some how-to website. Furthermore, the variables shown in the aforementioned image are not applicable/accurate to the cars we're discussing.
That in itself is still beside the point.
The point is that an Fully loaded 08 Odyssey can outrun an Civic EX in a straight line when both equipped with an automatic transmission.
Why? Simple. I made the assumption that both cars use long life/low grip tires, both have economically tuned transmissions, and both have the weight and power distribution as stated by the reviewing websites. With those highly probable assumptions, all you need is 2 people with a set of feet to do a brake load launch and floor it. If all else equal, we can safely assume that, a simple weight/power ratio calculation equates to the PROBABILITY* that the fully loaded Odyssey is quicker in a straight line to 60mph and 1/4 mile than a Civic EX.
*i use this word on the account of my assumptions and to keep you guys from having a hissy fit
Then, I then proved my assumptions correct with further research. I've found these numbers from comparison tests made by
Edmunds.com
I will show them again...
Civic EX 5A
Performance:
0 - 30 (sec): 3.5
0 - 45 (sec): 6.2
0 - 60 (sec): 9.6
0 - 75 (sec): 14.6
1/4 Mile (sec @ mph): 17.1 @ 81.7

Finally, all you who still want to believe that ryker's comprehensive equations will somehow put the Civic in front of the better equipped Odyssey can stop dreaming. Yea, Civic EX 5A is slower than fully equipped Odyssey, who cares the MATH that I've stated proves that this is understandable due to the weight/power advantage of the Odyssey.
