I think the PSS tyres is the key to the "superior" handling of the M135i. It is after all heavier than a 116i M-Sport, and should normally have slightly more sluggish handling.

Put an M135i drive train in a 116d and you'll notice a lot of differences. Huge increased of torque and horsepower place lots of extra demands on a chassis. |

Differences in handling include braking into corners, turn-in characteristics, agility, steering feedback, front wheel bite, stability under acceleration, mechanical grip, on-limit stability, transition to oversteer, propensity to understeer especially while braking, ride, stability on poor surfaces, accuracy and ability to adjust line.

I've been on plenty of spirited drives on these types of roads in my 125i only to look into my mirrors and see someone keeping up with me reasonably well in say a standard family hatchback. This of course doesn't mean the other car is just as quick or handling just as well. Its more down to the level you can really push on road conditions without wrapping it round a tree. Straight line speed is another matter.

I believe the information about the special setup of the M135i is mostly marketing hype. It might be slightly different to the extent that there are different part numbers, but the major factors for how the car handles is generally similar to the siblings.

I guess the guy responsible for it's development could have been lying of course as regards to aid marketing but suspect BMW's reputation would be greatly damaged if they did nothing and just changed part numbers to fool prospective buyers? I'm not saying I agree or disagree if it's true or not but just would like to know if you have any information that others may not be aware of? I think to exploit any chassis difference usually means driving close to it's limits so it probably correct that most drivers won't notice that much difference between some models that "might" or "might not" have been tweaked..

No, it is not based on any internal information. It is basically based on experience with previous generations of cars where they also said the same things. When the enthusiasts start comparing the parts, they are not very different. They are also usually interchangeable, so you can pick and choose between parts from different models to get the handling you want. On an E36, you may choose E30 front control arms, E46 damper mounts with Z3 reinforcements, Z3 steering rack and so on. All in all, the most important factors for the handling is how the weight is distributed in the car, stiffness of suspension (easily replaced) and swaybars (easily replaced) and alignment (easily changed). The weight is more difficult to do something about, and is a handicap for the M135i compared to the low power versions.
I am not saying that they are lying, I just think they are exaggerating the fact that the parts are different. It basically has to be to cope with the extra weight and power. You will probably find that the heaviest diesel models have a specific setup as well, but the marketing guys save the hype for the M135i. |

And of course the new parts have to cope with the extra power. If you're going to build an altogether faster, more powerful car, you have to make sure the chassis can cope with it. If you want to make a car go faster and handle better, you upgrade engine, suspension and brakes. That's exactly what the MotorSport engineers have done with the M135i. Hype doesn't bring you harder acceleration, higher lateral g-forces, shorter stopping distances and lap times within spitting distance of an M3. Last edited by SteveC; 02-21-2014 at 02:44 AM.. |

The standard M135i parts are pretty good, but not top shelf parts. You can upgrade the brakes further by going for the Performance Brakes. I guess they held back a little bit since it is not a 1M. |

There's no doubt that it can be faster and better handling yet, but not at the price point BMW defined for the M135i. |

I don't disagree with all that, but the standard 1-series should not be underestimated. With the right options (cheaper than the M135i), my opinion is that it will handle just as well.

Handling... compares to A45 AMG perhaps..... but there is no comparison compared to a CaymanS!!

Just to clarify
I misspoke. The comparison I referred to was between an M135i and a Boxster S, not a Cayman S.
To clarify, when I said 'bears comparison with' that's exactly what I meant.....worthy of comparison with i.e when journalists looked for cars to compare to the M135i they picked the A45 AMG and the Porsche Boxster S. That's not to say that the M135i is better than either car, simply that when looking for a comparison or benchmark.....journalist chose these 2 highly accomplished cars. |

The F20/F21 handling is rather unique, being the only RWD hatch in the market. That is why they have to compare it to very different cars. I guess they could pick the Toyota GT86, which would probably make the BMW come up short in the handling contest.

Thanks for all the replies. I have actually purchased an M135i and collect on Monday It's not the one i orignally spotted as that's been sold. Instead It is 4 months old and is fully loaded with options. I cannot wait. I got a good deal on my 125d and on the finance arrangement.
Cheers

Welp, i got the M135i last night. There is no comparison of these two vehicles. I am delighted with that i've got now in comparison to what i had.
That obviously will differ in opinion from person to person
