You are right. It looks like a set of 15's in the second pic.Maybe it's the angle, but the rims look smaller in the 2nd photo. They also don't look like the Competition wheels which give it a bit of a different look.
I can't tell if it is the smaller wheels or the color change, but the red one looks infinitely better than the concept.
It also may be that the red car doesn't sit as low, or that the body kit was toned down a bit.
In any case, it is far better looking.
Maybe, but I think it is more the color, composition and angle than anything.Maybe it was me, but did the buldge also look slightly...smaller?
Autozine.orgM3 gets fat
[SIZE=-1]Shortly after the prototype and the V8 engine, BMW has released specifications of the production M3. Basically, everything is unchanged from the prototype. However, the most interesting to us is whether it weighs more than the old car. In the press release, BMW stressed that the new M3 employs a lot of lightweight materials, such as a roof made of carbon-fiber reinforced plastic (like the previous M3 CSL and M6), aluminum front suspensions, forged aluminum rear suspensions and compound disc brakes. Moreover, the aluminum V8 engine is 15kg lighter than the old iron-block straight-6. Nevertheless, in the end the kerb weight is 1580kg (DIN), compare to the old M3's 1495kg and M3 CSL's 1385kg. So where does the extra fat come from ?
Anyway, thanks to the more powerful engine, the new car still returns a considerably higher power-to-weight ratio: 266hp/ton (old M3: 229hp/ton; old CSL: 260hp/ton). 0-62 mph is claimed at 4.8 seconds. The acceleration performance of the new car is never in doubt, but I have reservation about its braking - although the ventilated and grooved discs look big (i.e. 360mm front and 350mm rear), they are clamped by single-piston calipers like the previous generation. Now coping with the increased weight, the braking could continue to be the weakest link of M3.
Wtf. Single piston brake clipers?
A little interesting tidbit: Despite BMW's nonstop mention of lightweight components, and how the engine weighs less than the outgoing unit, the new M3 will pork up. A lot.

Uh, my message to the autozine.com guys: Hello. Welcome to 2001.
1580 kg is 3483 lbs.
The E46 M3, in base US spec weighed 3450 lb. I don't know where they got 1495kg (3295 lbs.) from, but that has no basis in reality, unless it's a dry weight. Also 3450 is without the heavy electric seats (~75 lbs. each) that were an option in the Premium Package. Loaded E46 M3s were over 3500 lbs. A base US spec E46 330Ci weighed 3280 lbs. with the manual, and that the included power seats which were standard in that car. All weights expressed are Curb Weights.
If the E92 M3 is only 33 lbs. heavier than it's predecessors, we should all breathe a sigh of relief because every series M3 ever produced was always significantly heavier than the basic 3-series it was based on.
(Yes, even the E30 M3)
The M3's most obvious competition, the RS4, weighs in at ... you ready?
Get this... 3957 lbs.
The number of pistons in a caliper is not especially relevant to a car's outright stopping ability. Remember that tires are what's stopping the car. If the car can produce enough clamping force to exceed the total grip of the tires, the number of calipers doesn't matter.
My Z4 M has 'only' single piston calipers and will stop from 60 in 115 ft, which is 7 feet shorter than an RS4, 2 feet shorter than a 997 Turbo only 7 feet longer than an F430.* (Road & Track Test Summary 5/07)
The advantage of a single piston design is lower unsprung weight and simplicity, so for all you guys complaining about weight, remember that adding mass to wheel/hub assembly is the WORST place to start doing it.
However, a disadvantage is the amount of brake pad touching the disc (total swepted surface) will generally be less than that of a multi-caliper design. This is why lots of people experience brake fade at the track in their Ms. If you have less total swept area, the heat generated from repeated braking will soaking into less total volume.
Of course, switching from a stock pad to a track pad and flushing out the brake system before a track day takes care of this problem for 90% of track users.

Wow. I find that kinda surprising, given that the larger GM Zeta/VE models roll in at about 4000 lbs even with the V8 and the automatic...
Here are a couple of photos of an Imola Red E92 M3. IMO, it looks much better in this color than Chrome Shadow on the concept car.
The Dumbo side mirrors are still looking ugly to me.

Story highlights:
- Article states the car in the picture is the production version
- US version to appear in mid-2008 as '09 model
- V8 weighs 445 lbs (202 kg) fully dressed. This is 33 lbs (15 kg) lighter than the iron-block S54 straight six in the E46 M3 and Z4 M Roadster/Coupe
- Engine redline incorrectly reported at 8400 RPM (it is actually 8300 RPM)
- Final drive is 3.82
- Article implies CF roof panel is a keeper for the standard car (ie, it is not reserved for the CSL version)
- Electronically adjusted dampeners will be an option --for the first time on the M3
