Iíve become quite good at predicting things for Honda/Acura, so bear with my crystal ball, again.
A typical Honda engine is tuned to deliver at least 90% of its peak torque from 2500 rpm, and attains 95% of its peak torque by 3000 rpm.
The 3.5/V6 in MDX was originally designed to deliver at least 95% of its peak torque (back then, 245 lb.-ft 3000 to 5000 rpm) between 2000 and 5500 rpm. With minor tweaks applied, this engine now produces 253 lb.-ft at peak (3500 rpm to 5000 rpm), and is shows producing 90% or more from just 1500 rpm. This means that MDX gets about 227 lb.-ft at just 1500 rpm.
The 3.5/V6 in RL is derived from it. So, it may have very similar torque curve at the low end, but since the peak is higher, 90% of MDX torque output isnít 90% of RL torque output. But, if I were to guess, I would say, the RL engine is producing at least 90% of its peak torque (or at least 235 lb.-ft) from 2000 to 6500 rpm.
If not at Wieck, Iím sure the torque curve is going to show up at Hondaís JDM website and I will be looking for it. As soon as I see it, you may find it here. Then we can validate the authenticity of my crystal ball. Again!

Well, add me to the list of people who don't like seeing a 3,984 lb curb weight. I think that the gearing will make up for the porkiness, but I can't help but wonder what the car would be like if it didn't need short gearing.
Otherwise, I like what I'm seeing. I was hoping for an extra 5 lb-ft from the V6, but that's not even worth complaining about. There's a good list of features, and decent interior space (according to the numbers).

I think there is an additional 5 lb.-ft or so, but Honda went with a well-rounded number (and I expected it).
I also think it would be rather difficult to trim down much weight off the RL outside of going to major design changes/widespread use of aluminum alloy et al. I'm sure the execs took note of it, but did the best they could. Its amazing how heavy the cars are getting these days. Look at the new Odyssey! It was heavy six years ago at about 4300 lb. Now it is heavier! At least fuel economy is expected to stay the same or improve.

Brilliant educational posts! Robertmx - You sir, are a scholar and a gentleman - My hat off to you!

I went looking through the pics for the Ody and they have a torque curve there. None for the RL, though.
Yeah, cars are getting heavy. I suspect that making them safe in a crash, silent on the road, and filled with goodies is simply one too many goals for a featherweight. But I was hoping that the use of aluminum subframes would have kept the weight under 3,800.

add another 1/4th pound... lol

3) Turning circle
Accord Hybrid anyone?
#3476 of 7386 No split folding rear seats? Argh!
Sep 01, 2004 (5:45 pm)
It appears based on the descriptions I've been able to find that the RL doesn't have split fold rear seats - just a pass through.
I was watching the RL with interest, but now it just dropped off my list for consideration. I don't understand why Honda isn't putting them in... The TL also became a non-starter for the same reason.
#3477 of 7386 Acura.com's interactive site for RL is up? - or down?

Messages 2019 and 2020, posted in the early morning hours of Sept. 1st, reference new content regarding the 2005 RL on the Acura web site. As of 9:00 pm EDT, same day, that content has been pulled, or the web site is malfunctioning. Although the RL prototype button is now gone, the new 2005 RL button only takes you to info on the NSX, MDX, and RSX, and the regular 2004 RL data remains. Were some erroneous specs published, I wonder, and subsequently taken down?

#3478 of 7386 Site is up
Sep 01, 2004 (6:29 pm)
I had the same problem trying to use Firefox browser. Tried the site with Internet Explorer and it worked fine. (Make sure pop ups are NOT blocked.) Its basically a mini-site for the new RL.
Sidenote - the interior is stunning. I want this car!
