M1 weight update today?

Not sure if this is new or not, but bmwblog.com is reporting this today:

"The new 1,500 kg M model is powered by an updated/upgraded N55 engine coming from the M Division producing 345 horsepower. The reason behind the M1 project is not to completely focus on power, but rather build a car more entertaining and thrilling to drive than any BMW ever built before."

Interesting, but if it's only 345hp, then we would really only expect a updated N55, and not a true S engine IMO. It will only feature a standard twin turbo as 345hp roughly is 250kw - we would expect max torque at 450Nm - that equates to max torque band till only 5000rpm - which is not much different to the N54.

Unless, the max torque stay at 400Nm, which would make the torque band to 6000, but would still be expecting it to redline only at 7000. If the engine actually peaks at 400Nm at 5000 and only drop off 25Nm each 1000 up to 7000 and redline at 7500, that would be a worthy S55 though.

Less weight and more power.

It's still a porker. That's dissipointing that the weight would not be less. 3300 pounds for this car is still heavy in my opinion. I kinda figured it would not have more power than 350 or so. Especially since the M3 will have a similar engine but more power. But I guess if these figures hold 9.57 lbs./hp is not to bad to deal with.

It cannot be, I cannot believe it. I will just wait until BMW M officially unveils the car and lets me test it.

The Z4 sDrive35is has a N54 in it. It has been confirmed by Scott that the M1 will get the N55 power plant.

Honestly, why on earth would BMW put an iS engine in an M car. Especially when we know the car wont be using an N54. I don't know where you get this stuff. Its almost as if you come here to purposely troll.

You are right. I was thinking it would come in around 32XX to be honest. Look at the M3 GTS though. The car weighs 328X. But BMW had to ditch a lot equipment to get it down 300lbs. Things like seats and airbags that tend to add up in weight so they got rid of it. I'm not even sure if that car has adjustable xenons and all the other electronic creature comforts one expects in a $50,000 BMW.

Most cars gain weight while gaining power. If this one dosen't, I say great. It must provide a more visceral experience as well.

Lets keep this On-Topic. There is already an engine spec thread.

Maintaining weight with the extra goodies like LSD and wider tracks I think is an achievement in itself.

at 345hp, I know there's more than power to an M car..... but I personally wont fork over 55k w/options for 345hp. Most ppl who have already driven tuned n54's probably won't either.

Its gotta have more than 345 under the hood. With only 345 compared to the iS's 340 on the Z4 sDrive35iS why would anyone buy this?

I don't buy the 345HP either. I was excited about the weight. Scott eluded to a weight reduction in one of his posts.

I have a question for everyone crying about the HP. NO N54 motor actually produce 300hp. It is a fact that it is underrated. Why wouldn't they underrate this one? I shouldn't be defending BMW here b/c finding an M1/1M wont be easy since its not here for long.

3300 lb is a LOT more than I expected. Can scott confirm these numbers? I hope its not true but assuming it is, is there a chance this will be a 135is? I think I'm just gonna keep my 135i now

Peak numbers mean squat. I want to see the hp and tq curves on an engine dyno sheet.

.....plus a fully integrated limited slip differential would also more effectively put down the power, which is, in my opinion, the biggest benefit of //M treatment.

that's an interesting point.

except it's quite a different story when it comes fully integrated with //M calibrated DTC as well as a full warranty, doesn't it?

or are you going to continue with your logic and also write that you can also tune a 135i to more than 345hp also?

you can add almost anything to a car, but when it comes as a fully integrated package from the manufacturer, you're starting with a foundation that is already superior to the standard car.

3300lbs at 345hp is good, depends on the driving dynamic. But it's not enough to definitively push the choice ahead of other cars I want
