The weight
I was surfing the web and i found some specs on the 130i coupe. The website says that the car weighs 3086 pounds. Is it safe to say that the coupe might possibly weigh less? 3100 pounds for the 3.0 liter U.S. bound 1 is amazing.

Had no idea the 130i hatch was that light! Anything around 3000 pounds is "light" these days and I'd be stoked if the coupe was that light. :headbang:
Only reason I can see the coupe we get being heavier is maybe things they have to beef up on the car because of more strict US DOT safety regulations? Does anyone know if the things they have to do to a car to make it pass DOT regulations for the US market makes the cars any heavier? |

Was working some #'s for fun assuming that we got a coupe thats like 3,100 lb and 300hp from the 335i engine. That would give the car a power-to-weight ratio of .0967
How would that stack up among other cars that are priced from 25-35k: BMW 135i/235i (300hp/3100lb) - .0967 2007 Nissan 350z (306hp/3340lb) - .0916 2007 Ford Mustang GT (300hp/3356lb) - .0893 2007 Infiniti G35 coupe (293hp/3524lb) - .0831 2007 Nissan Altima 3.5 (270hp/3294) - .0819 2007 Mazda RX-8 (232hp/3045lb) - .0761 2006 Audi TT (225hp/3230lb) - .0696 2007 VW GTI (200hp/3100lb) - .0645 And compared to cars priced 35k-55k: 2007 Corvette (400hp/3179lb) - .1257 BMW 135i/235i (300hp/3100lb) - .0967 2007 Audi S4 (340hp/3869lb) - .0878 2007 Mitsubishi Lancer EVO (286hp/3274lb) - .0873 2007 Lexus IS350 (306hp/3527lb) - .0867 2007 BMW 335i coupe (300hp/3351lb) - .0840 2007 BMW 328i coupe (230hp/3351lb) - .0686 Of course there's much more to a car than just hp to weight ratio but this was just for fun to see how a 135 or 235 might stack up and it looks like it would stack up great! :biggrin: |

Very nice numbers except for 2 things. There is no waaay in hell a 1 er coupe is gonna weigh 3100 pounds. In my opinion at least 3250 because a 130i coupe weighs about 3100. And it is almost a common known fact that BMW's 335i power plant is pumping out quite a bit more than 300hp. Good find though

BMW's UK website lists the 130i with M Sport package at 3190 lbs (1450 kg). If you compare the weight of the 335i Coupe (with the N54 turbo engine) to the weight of the 328i Coupe (with the N52 n/a engine), there is a 220 lb difference. Some of that is no doubt the turbos themselves, but there is also weight in the intercooling and requisite plumbing. There may also be some minor equipment differences contributing to the weight. Either way, if you assume a roughly 200-lb difference between turb and non-turbo versions, that would put the 135i at about 3400 pounds with M Sport package, which it will no doubt have. There may be some weight savings with a conventional coupe versus a hatch, but remeber the coupe also has a longer overhang. Any weight advantage would be minimal, perhaps less than 50 pounds.
So let's assume the 135i Coupe comes in at 3350 pounds. At 300 horsepower, that works out to .090 (.08955224) hp/lb. Slightly better than the Mustang GT, not quite as sharp as the 350Z. Nevertheless, it will still be a fast car. And it should still be roughly 300 pounds lighter than a 3 Series coupe.

It certainly will. With the #'s (actual hp and actual acceleration #'s) that the 335i is putting down, a car that's 300 pounds lighter with the same power and gearing will be an absolute rocket

I was reading in car and driver that the new M3 will weight about the same as the current one. (3500lbs). Thats amazing and kind've crazy how a lot of these bimmers are sharing weights although they have different engines. If the 135 comes with 3300 it might be seen as a porker but it would still kick some serious ass. no doubt about it!!

You have to remember that the weights on the BMW UK website are to EU1 (European Union) standards...which often makes BMW's appear to be heavier than they are ! (especially compared to some other manufacturers)
The EU1 weight includes an allowance for 68kg driver, 7kg luggage and 90% full tank. So you can take 109kg (68+7+34) from 1450kg = 1341kg unladen weight...which improves the power to weight nicely ;-) (I make that 2956pounds) I believe the N52 3.0i (alloy magnesium block) is 161kg, and the N54 (based on previous M54 3.0i) twin turbo is 195kg...so add 34kg or 75pounds onto the above for the 135ti. (but guess other bits might be beefed up as well) As a comparison the E46 M3 is 1570kg so take off (68+7+41) = 1454kg unladen. (3206pounds) Another comparison, the Z4 3.0i is 1385kg so take off (68+7+36) = 1274kg unladen. (2809pounds)...a fair bit lighter than the 1. |

Hmmm. If you go to bmwusa.com and look at the Z4 convertible. The unladen weight is 3086, not 2809!?!?!
But my guess for a 135i is that it will come in at 3250lbs. Which would be awesome. I mean 3100 is nicer but come on now, i dont expect it to weigh the same as a Z4. |

I believe that U.S. cars are considerably higher spec, but that tends to be balanced by the fact that we consider "curb weight" with half a tank of gas and no luggage -- but a fatter driver (of course!). On the one hand, the weight of opt. euip. would be a higher percentage of the 1er curb weight than it would a 3er; on the other hand, there may not be many heavy-weight options like body kits, 18-19" wheels, etc. All that said, your estimates look fairly close to the mark to me.

I still think that the "true" unladen weight will be about 3086 pounds for the 135ti...I'll be having the 130i personally as I enjoy more revs and less weight. (NB this "true" unladen weight is what Porsche quotes on their website in the USA and used to do in Europe (to make their cars appear lighter IMHO ;-)...I haven't looked at other USA spec cars / sites...probably the same tho') |

[quote=danp;2159 ...there isn't much difference in EU and USA unladen weights (i.e. they both include 250 - 300 pounds of driver / luggage / fuel).
quote] i could be wrong but my impression is that the eu adds 75kilos for passenger, luggage and fuel whereas the u.s. does not add anything. |

How heavy is light?
I'm foolishly hoping for small & light! I know modern cars are heavier all the time, but do we really consider 3250 lbs light?
Please forgive me... I've been on this forum for like 20 minutes and here I am complaining already. Where are my manners? I'll just cross my fingers and hope for a 3000 lb, 300 hp coupe. |

haha..its okay eMini. This car is all i think about. weight will be very important if it wants to win EVERYONE over. im not just talking bmw badge-whores. its the 135i weighs in at 3100 then that is just awesome for me. Instead of calling it a 135 they should just call it an M. The entry fee for the New M3 is so high that they would need another underneath to smooth things out. |

The 335i is basically a 3600lbs car. My guess on 135i, if it gets produced, would be then between 3300 to 3400lbs. Remember, modern cars are heavy. The STI and Evo, two cars that are as stripped down as they come for 4 doors, weigh around 3300lbs as well. |

You're right. Heck, I was shocked by how heavy the MINI is for such a small car. |
