Most Aero. Honda
 

Simple question:What year and model of honda besides the ultra expensive NSX is the most aerodynamic in stock configuration?:turtle:

2000 to 2006 Honda Insight .25Cd vs .32 Cd on the NSX

Maybe I should clarify...What if someone didn't start with a insight type hybrid and built up a small say D14 engine for max effieciency,couple that with a a crx or early civic. Bet that the fuel consumption would be close to what the new hybrids are getting due to the low weight and decent areo.!

Well, then I guess you'd end up with Ben's CRX (SVOboy)!

- Cd 0.30 in stock condition - his is now lower with the partial grill block and lowered ride height

- lean burn VX d15z1 engine and taller gearing

Ben's car is capable of ridiculously good mileage in lean burn mode on the highway. If he relaxed a little instead of blasting down the interstates at 70 mph, he'd be killing his fuel log with 70+ mpg (US) tanks in the summer.

Although, to be fair (meh), he hasn't had a tank below 50 mpg (US) since he did the VX engine swap.

Ben's fuel log

His web site: crxMPG - Gas mileage never looked so good

Here is my CdA list I threw together a while back. Lists many popular vehicles including all the Hondas I could get info on.

These are the top three:
Insight
CRX HF
CRX

Hey man, when I need to drive for 15 hours I need to get there, :)

Wow Thanks Metro and Doax, great info. Yes Ben's car is very close to what I had in mind. Just 1 point, is the 88-91 crx the absolute best choice weight and cda wize? Seems like the older 84-87 crx might be slightly better in the long run after just a few basic mods to clean up the Aero as it is 2 inch's narrower and undoutedly lighter. Or is it too narrow to accomidate that engine tranny combo?.

I don't know if the VX engine/transmission combo will fit in the older CRX. Not a Honda expert. Ben?

The US market first generation CRX Si (84-87) came equipped with a D series engine according to Wikipedia. I don't know how the mounting locations match up with later revisions. I am 90% an 88-00 D series is the same regardless of application, but outside of that no clue.

However, I have been tempted to follow OP's route after seeing several scrapper CRX Si's in the area for $500. Best of luck

The 1st-gen CRX will fit most or all D-series drivetrains. However, the mounting points are different, so it definitely is not a bolt-in operation. Also, the DX (or "standard") and HF models were carbureted, and used a different fuel supply setup than the fuel injection uses. So a fuel return line has to be added, in addition to any other changes.

It's definitely doable to swap a very FE D-series drivetrain into a 1st-gen CRX. It is easier to swap into the 2nd-gen car, though.

I'm guessing that the 2nd-gen shape is more aerodynamic than the 1st-gen one, but that's just a guess. The 1st-gen is smaller and lighter, though.
