OT but my wife used to own a Ford Escort. It was pretty much a POS. But it had a 5-speed MT and it had very light weight. My point is it was still fun to drive such a nimble little car. Can't compare it to a Si with 6-speed close ratio MT and LSD and real tires and real brakes. Except to say if the Escort was fun the Si must be fun-plus.

Which runs higher compression? I am guessing the Honda?.?.? I thought higher compression had to run a little richer to avoid detonation?????
I could be wrong, and often am on such matters......

I got the 2006 ratings from multiple sources. One of which is the temple of VTEC.
I was shocked when I saw the 22 mpg too.

What to see something
Toyota Avalon 22/31 MPG from a 3.5L V6 (268-hp 248-TQ) in a 3500 lb car that's as quick as the Si (avalon is probably quicker).

Hmm I wonder how these little high strung 4cylinders cant get better than 30 on the highway
Honda has had about 10 years since introducing the DOHC B series engines.... you think the fuel econ would pick up too..

This whole thing about V6 or 8 big liter cars matching I4 small motor is
b.s. Regardless wat EPA estimates. I believe it at the pump. Show me
the receipt on how many gallons you just filled and wat the mileage driven.
Then I'll believe it, I find it funny how it always doesn't add up.

If 22/31 is bad for the Civic, how does the S rate at 20/26? Both are 2.0L, right?
As a general rule, a sports cars with a given displacement engine will suffer in mpg realtive to a "regular" (family/economy) car with the same size engine and/or similar weight due to:
- wider, stickier tires (higher rolling resistance)
- engine tuning (for hp/tq rather than economy/emissions)
- gearing (for acceleration rather than economy)
- RWD or AWD (if applicable - lossier than FWD)
- styling (if applicable -- for appearance and/or brake & engine ducting rather than drag coeff.)
Performance always comes with tradeoffs in practicality.

Still too much gas consumption for the output/engine layout. I don't care if it is the performance version, it doesn't have that much performance to warrant that much fuel consumption.

might have something to do with the gearing. The Si is not very TQ-ey so it has to get up to revs very quickly to get off the line. So I guess in 1st it'll max out at 28-ish mph. (I think I read it will take 3rd gear to get 60 mph for the Si).
The 330i might have more relaxed (taller) gearing.
Also on the highway, say at 60 mph only requires say 60hp so the 330i may be turning 1500-rpms while the Si may be turning 3300-rpms. So esentially on the highway they could both be producing the same power and thus burning similar amounts of gas.
BTW I don't know the actual gearing or engine speed in gear but I'm just giving examples.

The 330 is a more relaxed car whilst the SI is almost as crazy as the S2000, in terms of revving and gearing.
I'd say the S2000 is one of the craziest cars out there, right beside the Elise. AP1 could rev to almost 9500 RPM, that's motorcycle territory. Cwazy!

I'm not saying the 2 cars should be compared, however (for me) they may be compared. All I need/want is a little coupe for DD. While the 330Ci will be a much nicer ride, it'll be doing near the same as a what I'd do with a Si. Going the same speeds and carving the same back roads. With the Si I'd be giving up 500-lbs of weight to the 330Ci so giving up luxury and refinement. But they could be close to the same size (inside) we'll have to see. But 99% of the time it's just me. So as long as I can fit either car is interchangable except for the much higher status and luxury of the bimmer.
that needs fuel.
