The BMW 1 Series is officially coming to the US: http://www.leftlanenews.com/bmw-1-series.html Like most of the new Bimmers, I am not 100% sold on Chris Bangle's designs... too much of a departure from the solid conservative designs of previous models. BUT the idea of having the 335i twin turbo 3.0L I6 in a car smaller than the 3 series gives me half a stock. I have heard tuners are starting to get good numbers from the twin turbo motor, but I kinda want to see how long the motor last pushing 400 lb/ft. Could be my next car... (in like 5 years...)
Meh... I'd save up for the M3, then I'd change my mind and buy a Z06.. not to keen on the newer designs either..
I have not done much research on it but one BMWCCA road racer here in TX have told me that he has seen multiple 335i's on road courses that have have quit mid session due to over heating issues :dunno
yea i heard of 335i heating issues but i've also heard that they have been resolved as for the 135i....i want it, it should be in the low 30's in guessing? but that thing can be a beast, its either that or e46 m3 for me later on
I think the only reason i like these cars is the motor... the mechanical engineer in me loves a straight six (esp with two turbos), and no one else is really making them much anymore. Sad:wtc:
i just don't understand why they would give the car so much power but no LSD to put it down.... it's all to keep it significantly slower than the m series cars .... kinda lame
You would think BMW would think about this shit. I know the twin turbo direct injection motor has some cool features. I heard they made the water pump an electrical pump with a thermostat so it only recirculates after the engine warms up (to get the engine warmed up faster for better emissions and engine wear). They also put the alternator on a clutch like the AC compressor, so it disengages under heavy throttle. All good ideas in my opinion. Only Germans would think of that shit but forget an oil cooler. :rofl:
It would be great if BMW really decides to make a car that is small and nimble and affordable like the 2002 and the E30 3 series. If the car's only 90 pounds lighter it's not the throwback that BMW claims it is. As for the styling I have never been a fan of the shark look. I had and loved driving my old '85 325e, although it wasn't a power monster.
has anyone heard that bmw has removed the dipstick from all their cars except for the M series idk if thats true but if it is...why? to make more money?
I don't think anybody is making the I6 twin turbo's anymore. Even Nissan is switching to a V motor for this baby.... :bowdown:
are there any other cars that are in/going to be in production that are TT besides 135i/335i and the gtr?
Starting from 03/07 productions, 335i w/ Sport package comes with oil cooler installed, which has eliminated most of oil over heating. Also BMW uses DSC (Dynamic Stability Control) to control the wheel spins (which is not good as LSD) during launching and cornering. I like the idea of 135i, but if it's smaller than 335i, it might be TOO small for many people
Actually what impresses me more is direct injection. Also can anyone enlighten me on the real benefit of running small identical twin turbos on an inline motor instead of a big single? Logically, I would think that the V motors would benefit from identical twins due to the reduced plumbing compared to a big single. A big single on an inline motor should reduce the plumbing requirements compared to identical twins.
a) its not a track car, stop comparing it to ones that are. geez b)bmw is still with the I6's. They don't make a v6 c)its not competing with the g37, that is the 335I's job D) milo, look at the torque curve. torque starts at 1400rpm(so you have practically full torque that low), and remains there in basicially a flat line up to red line. Kind of diesel like. With one turbo you'd yes get that fun kick, but also the lag we are all accustomed to. I'd buy it. Good size(for me), plenty of power, and it weighs about the same as my car I'm driving now.
I can see how sequential turbos can give a broad torque curve, but aren't the two turbos in the 335i identical and running in parallel? if so they should function similar to a single big turbo. A lot of the power characteristics of the 335i could be attributed to direct injection, not the fact that there are 2 turbos. Now do the tuned 335i's have that flat a torque curve? I'll look for some plots but please post them up if you have any.
took a little searching. they were all over when it debuted one from BMW: http://www.e90post.com/forums/attachment.php?attachmentid=22950&stc=1&d=1145968519 (sorry, cant make it imagize) heres one from an owner. It's stock and on 91 octane
The torque is not very flat and has the taper that is expected from small turbos. It is also making numbers similar to chipped 335i's. So I doubt it is stock. I'll do some searching around too
Maybe the compressor wheels are different so one turbo is for low end power and the other is for top end power.....
Actually, some more reading is pointing me in the direction that they are identical. Especially since they are setup for parallel operation. Here are some pictures Probably some interesting reading here: http://forums.nasioc.com/forums/showthread.php?t=943870
The coupe is puny looking, hopefully the sedan will look better. I agree though, the hatch wins hands down.
I am just shooting from the hip here, but maybe it just has something to do with clearance... I would imagine an exhaust manifold for a straight six to a single turbo would be quite long. Maybe they did two identical turbos to make the manifolds smaller. Or to get better gas mileage?
its not an m-coupe, thats just a z4 milo- granted that dyno isn't terribly flat. Some show flatter, guess its all in what dyno is being used. Still full torque from pretty low would be nice. also I'm saying it again, the 1 series does NOT compete with the g37. That is the 3 series coupes job.
The 1 series is a competitor with just about anything under $30K. It should do that quite nicely. I expect the 135 to be less than a STi or Evo. Not by a lot but still cheaper.
I'd expect the 'flatness' of the plot to be unchanged from dyno to dyno. The shape of the curve would be more reflected by the turbos and the tune. Regardless, this car should be pretty fun to drive. Now, I wonder how difficult it would be to upgrade turbos
