Weight of 135i Coupe...

[Driver72]

Hey there BMW brothers and sisters.

Over at e90post there have been lots of discussions and cross posts to this site where people seem to think the 135i is going to weigh as much as 300-400 pounds less than the 335i Coupe.
Months ago, I said no way and predicted it closer to 150 pounds.

Well recently I did a simple search on BMW AG's site of the listed weights for both cars.

135i Coupe = 1560 kg (unladen)
335i Coupe = 1600 kg (unladen)

That's a difference of 88 pounds!!

Now, BMW USA lists the weight of the 335i Coupe as 44 pounds heavier than BMW AG does. My guess is that's possibly extra emissions and safety requirements to the U.S. bound cars.
But if you have to add 44 pounds of emissions and safety equipment to the 335i Coupe, they'll have to add about the same to the 135i Coupe too.

So, as it stands it appears the 135i Coupe will weigh about 88 pounds less.

BTW, Car and Driver weighed a 335i Coupe recently without a driver and cargo and got 3366 lbs.
I decided to take my 335i Coupe to a California certified public scale and weighed it too. Full of fuel (filled up 1.6 miles away) and no other gear inside, my car weighed 3360 lbs.

I don't know how people think the 135i will weigh 200+ pounds less.
It has the same engine, same drivetrain, is only marginally smaller (but is taller) and is based on the old E46 3 series chassis. It probably needed some reinforcements for the extra power and added weight to the rear to make it close the the 50/50 weight distribution that BMW desires.

Just wanted to clear that all up.

That being said, I think the 135i Coupe will be a fun car for those of you who decide to get one.
Enjoy it and take care.

But... read the very buttom of the Data page, #1

but those extras are uniform for both cars ... except perhaps the size of the gas tanks ... leaving the difference probably identical.

in making the car shorter what are you really saving in weight? some frame steel and sheet metal? you still have to have all the airbags and fancy stuff that people expect of BMWs ... present company excluded of course.

it was funny that when i went to put down my deposit the dealer was saying there was a 700 lb difference between the 335 and 135. i knew better but let him have his fun and didn't correct him. really, i don't care. i just want the smaller car with the same engine.

The 135i will weight 3274 pounds. That is if you minus the weight of the driver.(U.S. curb weights do not include the driver)

And in actuality, I think BMW uses 15kg of cargo in the 335i (or 15 pounds more than the 135i they list above) Can't confirm that, but that's what I was told. If that is true, they actually list an additional 18 pounds of cargo for the 335i. Take that away to equal the 7 kg of cargo they list for the 135i and the difference in weight between the two cars would only be 70 pounds!

But chances are that BMW uses the same "cargo" weight for both cars.

But it's safe to say the 135i will only weigh about 70-90 pounds less than the 335i Coupe.

One other note of mention.
BMW states these are the "base" weights of each car and added options will increase the weight.

I believe there are more standard options on the 335i than there are on the 135i.

So, equally equipped, the weight difference could be even closer.

Again, point being, people who buy the 135i shouldn't be under the impression that it's going to weigh a huge amount less than the 335i Coupe thinking they are going to have some huge performance advantage, there will be some, no doubt. But future buyers should definitely take other factors into mind (looks, price, options, room, etc) when shopping between the 1 and 3 series.

That would be about right.
As when I (and Car and Driver) weighed the 335i Coupe without driver but full of fuel I got 3360 lbs (C&D got 3366).

That would be about 86-92 pounds more for the 335i Coupe.
Right where BMW AG lists the difference in weight as.

Ill wait till one of the rags puts it on a scale to get the real answer.

i agree with everything you said except for this... we will just have to wait though

like i said, for me, i like the smaller car even w/ the marginal weight savings.

And the six piston brakes and wider track then the 335i. :tongue:

I went to UK's BMW site last night and they have listed 335i M coupe at 1600kg unladen which includes the driver and other additional weight. So comparing apples to apples the 135i is only 40kg lighter than the 335i.

There is a discrepancy between the 1600kg unladen weight on UK site vs. the 3580lb listed on BMW USA's site. If the 1600kg is true then it should weight (1600-75)*2.202 = 3358lbs in the states but it doesn't. The 1600kg UK unladen converted directly is around 3523lb which is closer to the state's 335i weight but I thought US weight does not include driver. Even with the driver and misc. (+75kg) the US unladen weight is still 50-60lbs heavier.

I am suspecting US car is built differently than UK's and we can't compare the figures until US figures are released.

Also of note, the 135i is NOT based on the old e46 chassis.

It also has larger brake calipers all around, as standard, so that might account for some of the weight difference.

I don't know where you get that information from.

The 335i Coupe has a wider front track, wider rear track, longer wheelbase, 10 mm wider tires, and is 1.9 inches shorter in overall height than the 135i.

it's interesting because the last page of this brochure:
http://www.1addicts.com/forums/showthread.php?t=678

shows a rear wheel base of 1517 but if you look at the footnote it says it is smaller for the 135. that's probably where the confusion comes from.

You are right we'll just have to wait and see, but when I stated the 335i probably has more standard equipment I was talking things like:

Sunroof (it doesn't say it's standard on the 135i, so it may be optional)
Auto Climate Control (manual standard on 135i)
Logic 7 Surround Sound Stereo (135i says nothing of that)
Auto tilt and telescopic steering wheel (brochure says manual for the 135i)
and other things like the Ambient Door Sill lighting and so forth.

I can't read the tiny little writing on that brochure you linked about the wheelbase and track.
But on another one, it was clear.
That TheoIam is wrong, the 335i has a wider track, longer wheelbase, wider tires, and is lower to the ground than the 135i.

The 135i will probably be neat little car, but there's just a lot of misinformation about it at this point and I think too many of the 1 Series people who are looking to buy it are "pumping" it up with stuff that just not the case.

I personally would be more interested in it if it looked better.
Those "scaredy Cat" eye front headlights and odd proportions (tall domed roof) don't do it for me.
Plus, even though I'm not a big guy, I don't like too clastrophobic like car interiors.
I have a feeling the 135i is going to feel a bit cramped inside.

It should be entertaining though.

[Driver72]

Oh, what I'm also going to be curious about is dyno comparisons with the 335i
The 135i has a dual exhaust that runs into 1 single muffler.

The 335i have a true dual exhaust all the way back.

How is it that the 135i's exhaust wouldn't be more restrictive and therefore put out a bit less power?

The 335i is underrated by about 20 hp and 30 lbs-ft of torque.
There MIGHT be a chance that the 135i actually puts a few less hp to the wheels, but since the engine is underrated anyway, they can still claim the same 300 hp and tq as the 335i.

I could be wrong, but I just don't see how you can have a more restrictive exhaust, like the 135i seemingly has with only having a single muffler where two exhausts have to run together into it and therefore not make less power than the 335i's who have a true dual exhaust all the way back.
It may lie in the piping of the exhaust too. Since the 135i is shorter and has a different chassis, the piping of the 135i might be less restrictive than the 335i and therefore counter the more restrictive muffler system it uses. Don't know?

It'll be interesting to see some dyno comparisons of the 135i and the 335i on the same dyno on the same day and see the outcomes.

nothing personal but you seem rather defensive about all this. i mean if you aren't interested in the car why are you here? just to make sure we know the 335i is "better" apparently.

and again we have no clue what is standard in the US because the US documentation hasnt been released yet obviously.

i personally think it looks much much better than the 335i...but to each their own. i'm glad i have the option of the engine in a car other than the 335i.

cheers. :drinking:

And the lower price is a nice bonus too :wink:

The 535i will have the same setup as the 135i in regards to the mufflers and its still VERY fast. It also has more weight to carry. The devil is in the details. Dont forget on BMW quoted the the 135i to be FASTER than the 335i.

What he said. You seem to be making it a personal mission to justify your car.

News of the 135i is making the 335i boys quiver in their pants. They are looking for any means to find faults in the 135i. It's pretty ridiculous. When the e92 m3 magazine reviews were released they rushed into m3post and claimed their 335i can run with the new M3 at 20k cheaper. Now they are denying the 135i can be anything like their car.

Be happy with your purchase and drive.

The E46 M3 had a single exhaust leading into a backbox with 4 pipes coming out of it...and pretty sure they'd have made sure that this wasn't gonna be a restrictive exhaust...

I'm sure it'll produce as much power at the flywheel or wheels as the 335i

[Genericuser1]

Way I figure is the 335 is a great car, the 135 will be a great car, its a win win situation.
