The M3 is only 0.2 seconds quicker to 60 mi/h than the M340i?

Sorry not trying to start anything. I’m just eyeing on an M3 after finding my G20 330xi lacking punch. 0 - 60 mph (0 to 100 km/h) isn’t everything in a car, but I kind of expected a bit more from M3 (like, sub 4 seconds). What do you all think?

i believe BMW is under estimating 0-60 times.
X3M is evidence

0-60 is a function of grip, look at overall quarter mile MPH, that will tell you the full power range of available power throughout the powerband.

I think you should wait for the magazines to get a hold of production models and perform their own testing. I have yet to see a BMW not outperform their claimed performance times which are highly conservative much like their claimed HP/TQ numbers.

I don’t get it. 4.1-4.2 for standard M3 and 3.8 for Comp. Those are the same numbers as the previous generation M3. What gives? Increased HP, new car must be significantly heavier?

Yes new car is bigger, more length and weighs about 300 pounds more.

Many are giving the reason or excuse that BMW is underquoting G80 M3's 0 to 60. As at present, then compare BMW's official quote 0 to 60 for M3 vs M340i, m340I Xdrive ... what are they?

I'm more interested in 1/4 mile trap speeds.

It's definitely heavier, but the real increase is nowhere near 500 lb. F80 Competition models were over 3600 lb. so the actual difference is about 200 lb. Still it is a significant increase, no doubt.

Ya, yes I'm much more interested in steering feel, but pls note what this thread is about.

And yes, grip is an impt factor, and not sole determinant.

Oh, I saw some numbers in another thread that totaled that but maybe they were hypothesizing at the awd version

It would defy physics for the M3/M4 with auto and AWD to be slower in a straight line than the X3M Comp using the same engine and transmission given the X3M Comp is considerably heavier and less aerodynamic. I would expect sub-3.5 sec 0-60 and 11.5 sec @ 120 mph 1/4 mile from a ZF8 equipped AWD M3/M4 based on the numbers C&D got out of the X3M Comp. I imagine manual transmission RWD models will not likely be quite as quick in a straight line.

Probably worth adding the rear tires didn't get any wider/stickier so the there are still going to be similar traction limits.

And the base M3 still has the same torque rating as the previous gen which matters a lot more off the line

Add that onto the 200lb gain and you end up balancing out the increased horsepower for the base models


FYI for whomever was looking for it bmw rates the M340 rwd at 4.4 0-60

Thanks for posting that.

I had the delayed release of the RWD M440i stuck in my head and totally forgot the RWD M340i has, of course, been available for some time.

Traction (or a lack of) and increases in weight (quite a bit of weight) means the power to weight ratios are similar despite the power hike.

So you have a traction limited drive train and no meaningful increase in the power to weight ratio, so the numbers will look the same/similar.

You need AWD to get real improvements in the 0-60 when cars are this powerful.

Real M cars have never been about only 0-60 times. If you want that, get another car. M cars have been about the driving dynamics on a circuit. The M340i gets beat even by a less power full M2. No doubt the G80 M3/4 will demolish it on a track where it counts... if you care about that sort of thing. The G80 competition with the auto is sub 4 seconds. My F80 is sub 4 seconds... it's not the be all that end all.

Such a ridiculous thing they decided to do, make the M3/4 heavier than its predecessor.

Yes!

Speaking of, honest question I can't seem to find an answer to. I know the AWD M3 will be limited to Competition only. Regarding price, all I can seem to find is the $71,800 starting price which I imagine is for Core model. Has anybody floated what they think the starting price for M3 Competition will be? Figure +$3,000 on top of that for xDrive.

They got heavier with every iteration e30 onwards only the move from E9* to F8* lowered the weight a little.

But they are at the edge of how quickly a front engined rear wheel drive car can accelerate to 60 hence not much of a move forward if at all.
