RE: BMW M135i vs Audi S3

I spent quite a bit of time at 7000rpm, it never felt like my diesel, and it certainly didn't feel like it "dropped off" - 8spd ZF.
It pulled and pulled, all the way to the limiter, in every gear. By the way, this thread is Evolve with a standard car on the dyno http://f20.1addicts.com/forums/showthread.php?t=81...
The cars have more power standard than BMW quote (340ps average) and are only 20ps down on the 1M
The dyno was stopped at 6500- I don't see any massive "drop" in power over 5900?!
Stop talking like you've driven the car and making statement against it, when you haven't. The M135i has overboost and additional cooling vs the 135i as well as other changes - the 1M is different internally, so it wouldn't be a huge shock if this is too, being only marginally less power than the 1M itself.
Not a fan boy by any means as my views on the car are earlier in the thread - but the engine is not as you describe.
It's pretty much exactly as i described- in that graph the power starts dropping at about 6200, which is 300rpm later than the bmw published graph. The limiter is at 7000, and they arent going anywhere near it in that evolve graph, so the shape of the curve doesnt tell you anything about the top end - they stopped the plot at 6400, and it's dropped about 15% from peak already at that point, and thats not even half way from peak power to the red lineIt pulled and pulled, all the way to the limiter, in every gear.

You just confirmed my point

I didn't confirm your point at all.You just confirmed my point
Lets see another one hit the bump stops.
So it loses a whole 10-20 bhp at the end? Does this constitute a "diesel" engine, or power dropping like a cliff?
You haven't driven the car - but people who have on this thread don't agree with your theory.
Try one, you might surprise yourself
I'd have thought it'd be less frustrating for most drivers who want to make maximum progress to have a little bit of a warning you're approaching the red line rather than get caught out by slamming into the limiter. You can't always be watching the rev gauge when in that situation and it's only 400rpm warning which I'd imagine doesn't last a long time in an M135i. Meh!

I just bought a 125i, maybe I should have bought 2. They're not going to make them like that anymore...
Hang on, isn't the 125i a turbo 4?

If you want more of that delicious induction sound I'd recommend a mod I've made to my 328. Decided to make my own sound symposer and ran a 1.5 inch hose from the airbox to the ventilation system inlet. Had to make the necessary holes in the dirty side of the airbox and the ventilation duct panel, but now have surround sound straight 6 induction which I have to say is frikkin sweet! I originally fed it right into the cabin through the bulkhead which was louder but a bit hissy and decided I didn't want the engine sucking in warm air from the cabin in winter and also it sounded quite artificial coming from just one place.Best thing I've done to that car and it only cost a fiver for the pipe

That graph is nowhere near as bad as I'd expected to see from what people have been saying, it looks like it holds up much better than the engine in the 1M at the top end.
Still definitely not my type of engine, but probably an acceptable evil for the fuel economy the turbocharger gives if you cover big mileages.
I was expecting to see this type of graph (which is absolutely horrible):

Was it plotted in windows paintbrush?

No idea, it was just the first graph on google images and that's about what the old lump feels like. Expand the X-axis' scale by 50% and it would look very much like a diesel. Was it plotted in windows paintbrush?
It's good to see that BMW have managed to improve the top-end of the new engine.

The second one you posted looks completely different, and not nearly as bad.
I'm not saying it's a bad car, i might even be tempted by the M235i as a daily driver, since it looks considerably less horrible
But it doesn't have a "glorious finale" !!!!

Again I have to repeat, you can't criticise someone else's opinion of the car without driving it. You are not in a position to do so by looking at a graph.The last 500 rpm do not feel like a diesel at all - it still has over 300 bhp. It is fast. It sounds fantastic past 6000rpm, really aggressive sound.
