My Accord and CRV - same engine - different output?
Hi,
My family has two 2005 Hondas; CRV and Accord LX. They both have the same four cyl engine. Hower, I noticed that CRV seemed to have more pull. So I checked the engines specs on OwnersLink web-site.
Accord Specs: 160 hsp 160 pound of torque at 6,000 rpm
CRV Specs" 160 hsp 162 pound of torque AT 5,500 rmp
I also noticed that CRV's enginer air filter is much bigger.
Why this difference in specs and why didn't they program the Accord's engine to have torque available at lower rpm?

The more "jump" is probably in gearing rather than the motor. 2ft-lbs and a difference of 500rpm (at already high rpm) isn't detectible. Gear differences are detectible.
IMO, that difference isn't worth thinking about.

The K24A1 is in the CRV and has 9.6:1 compression. 160HP at 6000RPM and 162 lb-ft. at 3600RPM.
The K24A4 is in the Accord with 9.7:1 compression. 160HP at 5500RPM and 161 lb.-ft. at 4500RPM.
It's mainly an issue of tuning. The CR-V's has a slightly lower compression ratio, and a much better torque band at a lower RPM. Torque is key for a heavier vehicle to get up and go. This comes at the sacrafice of top end power, where CR-V owners are less likely to stretch the needle to.

Hi
I gotta tell you, I drove both cars and CRV feels much faster up until 80mph (I did not go over that). CRV just feels more powerful - and yes, mine is all wheel but rear wheels kick in only when front start to slip (hydro clutch set up).

The torque and HP numbers as well as teh weight is close enough, that it's not a factor. The biggest difference will be gearing. The CRV has much shorter gearing so it applies greater force in each gear. The drawback is lower mileage and more engine noise at freeway speeds.
The seat-of-the pants test will favor the CRV because it's taller. You'll have a greater sensation of being pushed backwards. The CRV is also a noiser car, it will sound like it's accelerating faster. SHorter gearing also spins up the RPM's quicker even though redline in each gear is at a lower speed.
There are 2 other tricks to fool a driver. The speedometer goes ot 140, vs. the Accord 160, so the needle will appear to move faster. The tachometer in the CRV is also larger and the needle will appear to move faster (short gearing also causes this as well). The last trick, is that Honda might have a shorter travel accelerator or the angle of your foot might make the pedal feel more touchy. GM was known to give cars very touchy gas pedals because it makes the car feel more powerful that it actually is.
