It doesn't add much/any with DCT.

Only corvettes/Ferraris/Vipers do it in first gear and few other exotics.
Hint: Large displacement V8+ only

Just launch in 2nd and replace your clutch more often if you want no shift to 60!

Ok, by "shorter" it means that the final drive would have a BIGGER number, and vice versa for "taller".
For example: 3.08 is taller than 3.43. If the gears stayed the same, but you changed the final drive from 3.08 to 3.43, going shorter, accel would increase and top speed would decrease.

If you left the final drive alone, but you changed 2nd gear to be 'taller', you'd go from let's say 2.32 to 2.11. Accel decreases and top speed increases.

Please explain what your argument is standing on?
Maybe I misunderstood.

All Bmw's I have run numbers on have the car hit 62 mph in second gear. There may be exceptions, but I am not aware of them. The 1M is using a 265/35/19 tire that is about 6% taller than the stock 245/35/18 135i tire. The 1M engine has about 500 rpm more useful rpm the the stock N54, or about a 7% wider power band. My guess is that BMW might use a 3.46 to cover those 2 differences.

Don't shoot me if I am wrong, but it would match what they have done elsewhere. They might use something a little lower like a 3.23 if the 1M is getting too close to the M3.

I am glad this has come up. One of the reasons M cars are always quicker and feel better is that they are geared for performance not mileage and they usually get all the gear they can use to make it to 62mph in second.
I ran some numbers using the M3 gearbox with the larger tires of the 1M.
Here's what I got on the 1M with the 3.85 FD. Gear-top speed at 7k rpm.
1st- 35.05
2nd- 59.3
3rd- 90.07
4th- 119.59
5th- 142.32
6th- 163.58


I would think that BMW would want to go a bit taller on 2nd to get it to 60mph, if they are concerned about advertising that all important number.
Drop in the 2.32 second gear ratio from the 135i MT, and mph goes up to 61.34mph.
Better selling number with only 1 manual shift instead of 2.

What numbers did you get?
The calculator I am using is acting funny.

Here's the 1M with the 135i MT gear ratio's and the M's 3.85 FD.
1st- 34.63
2nd- 61.34
3rd- 92.41
4th- 120.61
5th- 142.32
6th- 167.43

If these numbers are right, then it might be better to use the 135i's MT gear ratios with the M's FD LSD.

I don't recall the 1M engine having any more revs though.
Some reviews said that the engine felt like it pulled stronger all the way to red line, some didn't.
But, I think red line is still 7k.
Have you seen it at 7500rpm for red line?

Thank you Mr. Scott Lawrence Mosher, for posting this.

Subscribed.

$43,000 base price.
Zero-SixtyTWO mph 4.3 sec.

Could you or somebody PLEASE reconfirm these 2 numbers and be my hero?
These deserve a reconfirmation because, 1, they are really good, and 2, they are very different than what we've been hearing so far from other sources.

Thanks again.

Actually the 4.3 makes perfect sense given the 340hp, 3300lb, 3.85 diff ratio combo for this car.

Now the $43k base price? It's gonna be quite the stripper to get that price.

Well, you can forget all that. The new car is fitted with a turbocharged straight six. Turbocharging? In an M car? That’s like putting gravy on an ice cream.

Non-sense at 4.3 0-62mph its fully loaded! Anything more would be too civilized!

Hopefully the 43k base price will NOT include a moon roof.

Im still hoping we get the performance seats at that price!

What are "the performance seats"? Are those the one piece back, with belt holes by the shoulders? Have those come in ANY recent BMW? I love 'em, but don't expect them to be even available.

Yeah the Recaro like ones with 5 point harness holes. I've seen pictures of people with new M3's (and a 1er) that have them installed.

I could not find them on BMW's site currently tho.

I think it can, especially thanks to gearing, unless they use the M3s gearbox gear ratio's that might require 2 shifts to 60, then maybe not.

I still don't think that will be BMW's advertised number though.

4.3 sec. 0-62mph (0-100 km/h) is just dream-land. As RPM90 showed earlier, a 3.85 final drive will result in 2 shifts 0-62 if they take the M3 or 135i gearing.

135i trans gears and 7100 rpm = 62.16 mph in 2nd gear . . .

So, even with an actual redline of 7k, as long as the limiter doesn't kick in until 7100+, you wouldn't have to shift.


Will BMW publish that number? No way. It'll be listed around the M3/Z4iS range.

Still, bottom line is, with 3.85 diff gear and 340hp+, this car is going to accelerate well, across a broad RPM range.

If the 335is was track tested by C&D at 5.0 seconds from 0-60, I'm having a difficult time believing that this car can shave nearly a second off that time, based solely on gearing. Other factors must also play a big part, like LSD, wider tires, weight distribution, drag coefficient, weight, suspension, tire friction, throttle mapping, and I don't know what else.

Remember, 4.3 0-62 translates to 4.1 or 4.2 0-60.
