Ok, I know the 335i is a much nicer car to many of you, but thats not what this is about.
I used to own a 350z as my first car and now that I'm comfortable opening up my car on the highway I feel that my old 350z felt much more powerful.. I'm not too worried about speeding, but more of "is something wrong with the car"
Is this normal? I thought 335i have the same acceleration if not better by a very small margin.. I'm not too technical with cars, but maybe it's the different power curve/ delivery? I doubt the previous owner abused it to crap. I would be very happy to hear your thoughts on this.

Maybe it's just my imagination, but I'm going to go test drive one some time this week. It's just bugging me a bit.

A 350z is NA, the power delivery is ALOT different than the torquey n54.

[eamon]

well that was quick.
But if it IS torquier, shouldn't it feel faster?
So this is just more of how the car is supposed to feel and it isn't just my car..
I really am not too good with this stuff yet.

I came from a 2003 g35 coupe to my current 07 335. The 335 kills the g in every category (including highway pull).

Not necessarily, NA cars just slam you in the seat(feel really fast) as opposed to turbo car slowly shoves you into your seat at a slower rate although they are pulling harder it just didn't feel like it. At least thats the way I've always interpreted it.

[username604]

lol idk if it's cause my car's an auto or what, but when i kick down, it pushes me pretty hard into the seat...

[Mr.335iCoupe]

This is from personal experience. From switching back and forth between japanese cars and my bmw, I've noticed that the throttle response in japanese cars are way more sensitive. The power delivery is immediately but dies down during the last few thousand RPMs. In the 335i however, the throttle response is less sensitive and the power builds up and continues throughout the RPMs. I'm pretty sure BMW makes their cars this way to achieve the smooth driving experience. And when referring to the quickness of the car, it could be your mind playing tricks on you. Think of it like this,

350z/G35 - Sensitive throttle response and earlier full power delivery = throws you into the seat making it feel faster.
335i - Less sensitive throttle response and later full power delivery = slowly pushes you back into the seat making it feel slower.

You can also look at it like this:
Japanese cars just don't feel as solid as bmws. You ever drive 85+ on the freeway and feel like you are going 60 in the 335i? And have you ever driven a g35 or 350z going 85+ on the freeway? Not sure if you understand that, but it's true.

[Elie335]

lol @ 350z

[XDEEDUBBX]

your ears may deceive you as well, 350z's and G35's are way louder stock than a 335i. There's no way in hell a stock 350z or g35 is faster than a stock 335i.

[FVM3]

maybe 370z but not 350z

I definitely think this is your mind playing tricks on you. I drive a G35 and my best friend's stock 335i is waaay stronger throughout the rev range than my car. I think it may be the sound difference as the G35/350Z have a mean growl at WOT.

[Wild Squid]

I kinda know what you mean, my old 1998 Mustang GT with only 225 stock horses felt faster in the low end than my 335i. The 335i doesn't feel like it has any oomph until past 4k rpm, then it just flies and you quickly run out of road. But I do wish the power would kick in a lot earlier.

COBB AP!

[Mr. Nice]

stock for stock I think it would be close between the 335 and the vq35hr, 335 would easily take the de, 370 would be faster, talking stock 1/4 mile comparisons achievable in the real world by an amateur driver. VQ definitely feels like it's pulling harder in higher rpms, just get a tune.

[bill1718]

throw a jb4

[blinkme323]

FWIW - I came from a 370z to my 335is and the 335is feels just as fast if not faster.

[onebadmofo]

When I was dynoing my car there was 370Z with CAI and full exhaust. He put down around 280. I put down the same 280 stock but then I switched to map2 on Procede an put down 335hp/370tq.

The thing about the N54/N55 is that the torque curve is flat. The power can't possibly kick in any earlier than it already is, which is already happening well below 2000rpm. What you're really talking about is torque, and you just want more of it. Maybe you should've gotten a diesel.

My experience with my 135i was that the acceleration was linear and uneventful, because the torque peaked at a low RPM and just held steady up until around 5500rpm where it starts dropping off as the boost tapers.

A non-turbo motor will have a torque peak higher in the RPM range, which is why it can feel faster at higher RPM's because the acceleration increases as the torque climbs.

Don't you have that completely backwards? A NA engine slowly and evenly builds power as you go up the rev band, whereas a turbo engine doesn't build any power intially (turbo lag) and then BAM, the turbos spool up and you get a surge of power....?

[Q4P]

Oh Boy, as always a good bit of misinformation here. A turbo car does not have a flat torque curve, in the case of the N54/N55, the curve slowly rises and then falls, then eventually past 5K falls flat on its face. If you wanna see a flat tq curve, look at an M3 Dyno, flat tq curves are more of the nature of an NA engine. In the 335i, you will feel a ton of power down low which will then be matched with horsepower in the higher revs, this is proved by looking at any stock dyno graph. The engine might not be as responsive as the Z but that is because of "turbo lag" which in the case of the 335i is absolutely minimal due to a small twin turbo setup. Any NA engine will gain power more gradually as you go up in the rev range but it definitely will not punch you in the face or kick you back in the seat as a turbo engine will. In the case of the 335i vs 350Z/G35, there is something seriously wrong if you do not feel a massive power surge and the car does not feel amazingly quicker than either of those. I have experience driving a G37 which is way up on HP and TQ from the 350Z and it still did not feel as fast as a 335i due to the availablity of so much TQ down low from the turbo powerplant. It was the same case when a friend of mine was purchasing a G37 and I told him to go drive the Bimmer, he drove it and was amazed at what was offered from the engine. He ended up buying a 135i...

Exactly what I was gettin at....

Maybe you were just a car noob when you had the 350z so it felt faster to you?

[O HELLA BMW]

I had a g35 coupe and I thought that was fast until I got my 335i lol

But one thing I can't deny is that the stock G/Z exhaust note sounds sexy
