Differences / similarities?

From Honda's lit -

3.5-liter, SOHC, VTEC V-6 engine (Coupe EX-L V-6: 6MT)

· 268 horsepower at 6200 rpm, 248 lb-ft. of torque at 5000 rpm
· 6-speed manual transmission
· VTEC provides two intake cam profiles for increased low- and mid-range torque
· Estimated EPA mileage of 17/25 mpg City/Highway2
· ULEV-2 emissions

 

Thought the type-s has 286 HP ?

 

^^ I ate one of those bmw wanna-be's recently.(4 door) Maybe they detuned the rl 3.5 even more.....

 

The newer 07/08 TL-S does have 286HP.

 

AFAIK, it's the same engine, only tuned to accept 87 octane.

 

few things

the accord is i-vtec... we are not.... i-vtec makes the actual vtec enhacements more noticeable.. detuned to only 268hp... the cams are not hollow... the engine isnt made up of as much lightweight aluminum as ours

I've heard a rumor, i dont know the validity behind it, but my friends who has an 08 V6 coupe said it has one of those like "gas-saver" type of things, where when you are cruising or coasting at a solid 60 on the parkway, part of the engine shuts down to save gas (kinda like the hemi's).... i dont know how true that is though

 

yup its Honda's VCM (Variable Cylinder Management) available on the V-6s and allows for either 2 or 3 out of the 6 cylinders to shut down to increase fuel efficiency

LINKY for those of you that are interested

 

It should be a SOHC iVTEC VCM 3.5 V6

They're not going to bump it up to 300 because it would impede on TL and/or RL sales; though with it at about 270, and the current TL at 258, one can hope the base 4G will be at 300!

 

I drove a NEW Accord (coupe + sedan) b4 I leased my 2008 Type S. The Accord was nice, but too bland & just too ordinary = no personality. It does have 268HP + cylinder deactivation (a little annoying light kept coming on dash telling you!!).
The coupe was a little "cooler" looking than the sedan, but not by much...........the Accord looks like the "love child" of a BMW + Hyundai.
For me, once I drove the TL Type S.........I was SOLD. The Type S just had so much personality.........and personality goes a long way!! (Pulp Fiction quote.....ha!!)

 

My brother and I drove both a new 190bhp K24 Accord and the 268bhp J35 Accord. Your mileage may vary, but here's my take... Both cars felt much better than the Accord they replace. The chassis feels pretty solid, the suspension didn't wallow or feel overly abrupt. I think they did a good job tuning the suspension, especially considering how large the car is now. I swear it feels like it's larger inside than my TL-S.

I thought the 190bhp K24 would feel kind of similar to the K24 in my former '06 TSX but I was sorely disappointed. It didn't impress me at all, and it actually felt like the power started to run out a bit as the engine got revved up really high (like the VTEC cam lobe switch wasn't occurring?). Not sure what's going on there, but it was totally boring, leaving the '06 and later TSX with the only exciting K24 in my opinion.

The 268bhp J35 was smooth and sounded pretty tight, as expected. It had a wide and extremely flexible powerband making for effortless driving. However it really didn't feel like it had the ultimate punch that my TL-S has. In a drag race, I feel like the TL-S would get ahead right out of the gate and stay there. And if you're really trying to hustle, the handling on the TL-S is much more reactive and nimble.

Acura is clearly Honda's "upscale performance" brand. While the latest iteration of the Accord sedan is very good, I doubt it will outperform it's cousin over at the Acura dealer. And if it ever did, it certainly wouldn't feel the part like the Acura anyway.

I would like to drive the new Accord coupe with the V6 and a 6 speed manual. I think the coupe is beautiful, and Honda claims there are some features unique to the V6 6 speed, like a revised intake system, etc.

 

i always questioned this and no ever gave me a good answer i could trust.

What's the difference between I-VTEC and VTEC

 

i always questioned this and no one has ever given me a good answer i could trust.

What's the difference between I-VTEC and VTEC

 

it all has to do with the lift & duration of the cam lobes... and something like that

basically, the i-vtec is ""supposed"" to be alot more noticeable when it kicks in.. not neccesarily more effective, just more apparant.

drive an 06 RSX type-s (i-vtec), and then drive a 2G/3G CL/TL/AV6... you cant really feel the vtec kicking as much... its kinda hard to explain

 

I believe only the Sedan's V6 has VCM (Variable Cylinder Management) not the Coupe, and only the 4 cylinder engines have the I-Vtec, not the V6s. Those motors, the MT V6s, are getting 239whp and 224tq on 91. They guys at vtecdotnet dynoed a guys v6 mt accord as soon as it hit 1000 miles breaking period, and at 239whp on the dynojet, it came close to what some guys are hitting on the TL-S that i know, (245-250)

The reason it has lower compression than the TL-S 10:1 versus 11:1, is to be able to run 87 octane.

 

my yzf r6 has a 12:1 compression ratio and 87 octane is recommended...

 

I agree with you there. My cousin has a mildly modded RSX-S and that thing goes crazy at vtec range.

 

From googling:

VTC - Variable Timing Control. This is a mechanism attached to the end of the intake camshaft only which acts as a continuously variable cam gear - it automatically adjusts the overlap between the intake and exhaust cams, effectively allowing the engine to have the most ideal amount of valve overlap in all RPM ranges. VTC is active at all RPMs.

i-VTEC - intelligent Variable valve Timing and lift Electronic Control. This is a combination of both the VTEC and the VTC technologies - in other words, i-VTEC = VTEC + VTC. Currently, the only engines that use the i-VTEC system are the DOHC K-series engines.


I think VTEC engages based on engine RPM / oil pressure; iVTEC activates based off multiple factors I believe

nice link - thank you

high $$$ production values

 

i think the VTEC on the type-s sucks. the car is fast as sh*t but no change when i go all the way up to 6500 rpm. I only have about 2010 miles on the car and I read somewhere on here that vtec doesn't engage till you reach 5000 miles, is that true? I'm starting to think that the type-s doesnt even have vtec.

 

I looked at something that said that i-vetc worked on the intake side while vtec works on both the intake and exhaust cams. Honda uses vtec on the race engings and on NSX, S2000, etc. I'd rather have vtec than i-vtec.

 

It has it but between the intake and smooth activation you won't hear or feel it as much as the older vtec's. If you have a stick or just put it in sport mode for automatic, leave in third and a low speed (30mph) and then floor it. Its slow at first but as it goes faster and you get to the majic # you will hear and somewhat feel the vtec crossover

 

i-vtec is vtec and it also adjust timing on the fly from the sprocket. The rsx type s has vtec on both sides with timing adjustments also. It works like toyota's vvt-i and the mitsu's mivec.

 

I GUARANTEE you the TL-S has VTEC. It kicks in around 4,800 RPM, the engine screams and the car LEAPS forward.

As suggested above get into 2nd or 3rd at moderate RPM's (say 2,500), then floor it. Pay attention to sound and feel as you go through 4,500 RPM.

I have read that VTEC will not engage unless you are at WOT - can't confirm that though.

 

The whole thing is that the VTEC system used in Honda K series engines is a lot more complex than what is used on the J series. In the K series i-vtec varies cam phasing, on the other hand i-vtec on the J series is only found on the Accord because it has Variable Cylinder Management.

 

Thanks Kobi and Bearcat. I actually tried pushing my car again tonight and I still don't notice the VTEC. I have the 6MT and on second gear I let let it reach 2,000 rpm before I floored it. I guess honda did a good job by seamlessly integrating the VTEC when it engages. Not for nothing, it doesn't even matter cause the car is a beast. Also, what does WOT stand for? I'm not quite up to date on my acronyms.

 

try 3rd gear at about 2000 rpm and floor it and listen real good. I hear mine every now and then

 

I don't think the Accord V6 has i-Vtec. I had a brouchure and I think only the 4 banger had i-Vtec. I will check if you really want to know.

 

OK, I found the Accord brouchure. FACT: The 268hp V6 in the Accord with the automatic trans has 10.5:1 compression and is a i-Vtec engine. The V6 with the manual has 10.0:1 compression and the engine is a regular Vtec. By the way, this is the Coupe. The sedan doesn't offer a manual. So any automatic V6 Accord does have i-Vtec. WEIRD.

 

Nice find JD TL-S. What's up with that!?! I went to Honda to build an Accord:

Automatic 5 Speed:
268-hp, 3.5-Liter, 24-Valve, SOHC i-VTEC® V-6 Engine
Variable Cylinder Management™ (VCM®)

Manual 6 Speed:
268-hp, 3.5-Liter, 24-Valve, SOHC VTEC® V-6 Engine
NO VCM!

 

so it looks like the 6MT has the advantage... as always with hondas

<---sad he got a 5AT, but had no choice!

 

WOT = Wide Open Throttle.

 

I just checked on Honda web site. For 4 bangers, they have i-VTEC on both 4 and 2 doors. For V6, 4 door model has only i-VTEC, with VCM. 2 door model has both VTEC (6mt only) and i-VTEC (5at only), with VTC and VCM.
