I was thinking of manual gearbox.

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. |

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? |

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. - Jeremy Clarkson, discussing the S65 and then S55 M3 engines. |

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.

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.

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.

BTW, those Michelin Pilot Sport PS2 rear tires - $400 each from tire rack. Ouch.

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. Last edited by blueshark; 01-29-2011 at 10:55 AM.. |
