Not the kind of comparison we see every day, but our friends over at Edmunds are feeling adventurous today and gives us an unexpected car comparison: BMW M3 Sedan (E90) vs. BMW M3 Coupe (E92).

Two great cars from the Motorsport division with similar customer target, but a different approach. One it’s a two-door luxury sports car that sacrifices some of the comfort of having a rear-door, and the other one, is a four-door sedan, an impressively well balanced vehicle that could do wonders on track if it’s placed in the right hands.

Both cars are powered by the same S65B40 engine, a naturally aspirated, high revving 4-liter V8 (based on the S85B50 5-liter V10 that powers the E60/E61 M5 and the E63/E64 M6 to date) delivering 414 horsepower (309 kW; 420 PS) at 8,300 rpm and peak torque of 400 Nm (300 lb-ft) at 3,900 rpm, which represents a power increase of 22% over the previous generation E46 M3.

As tested by Edmunds, both cars wear Michelin Pilot Sport PS2 summer tires.

But let’s have a look at the numbers registered by the two cars in Edmunds’ unique test.

2009 BMW M3 Sedan
$67,370 (as tested)
0-60 mph: 4.5 sec (with 1-ft rollout)
1/4-mile: 12.9 sec @ 109.8 mph
60-0 mph: 105 ft
Slalom: 70.0 mph
Skidpad: 0.90g
Weight: 3,710 (as tested)
Fuel economy (avg): 16.0 mpg
Tires: (F: 245/40ZR18, R: 265/40ZR19)

2008 BMW M3 Coupe
$65,775 (as tested)
0-60 mph: 4.3 sec (with 1-ft rollout)
1/4-mile: 12.7 sec @ 112.0 mph
60-0 mph: 100 ft
Slalom: 73.3 mph
Skidpad: 0.95g
Weight: 3,590 (as tested)
Fuel economy (avg): 15.6 mpg
Tires: (F: 245/35R19, R: 265/35R19)

Facing a dilemma already? We do too and we’ve been agonizing over this choice as well. The sedan seems to be moving at the top of our list…..

  1. CarGuyDad says:

    There is a mistake in tire sizes… says that the coupe has 18s in front and 19′ in rear… and the two cars have different tire profile size.

  2. X5 SoB says:

    The coupe is modestly superior to the sedan, as it should be. The only area that the sedan is better is fuel economy, again, as it should be.

  3. E92-TORONTO says:




  4. The E90, facelifted M3… is the first Sedan ever from BMW that actually looks better than it’s coupé counterpart….!

  5. Auday says:

    I dont get it, they have the same powertrain , the coupe is lighter and it looks like it has a better airodynamics, so why does the sedan have a better MPG?

  6. Saleem says:

    I say they have equal appeal. but the sedan wins in my book 4 doors are always better

  7. Babken says:

    Both are made with God’s help.

  8. Saleem says:

    Guys check out this story The BMW gave the Caddy CTS-V which was supposed to out do the M5 an ass whooping it shall soon never forget LOL LMAO.

    BMW in turn gave this suvillian a multifunction enhanced steering wheel. What a life I love cars.

  9. John Hietter says:

    What awesome cars. Great comparison idea. I think the carbon roof on the coupe does it for me. : )

  10. joe says:

    4 door is for those whom are married with kids but still has that racer personality, for everyone else the coupe is the car to drive

  11. BMfan says:

    The coupe will always win my liking. its just too sporty. fell helplessly in love with it the first day i saw in real life.

  12. Josh says:

    I’ve noticed, from numerous experiences behind the wheel of both cars, that the E90 M3 has better driving dynamics. Not by much, but still enough to notice. There is a small weight advantage for the E92 M3, but when you chuck an E90 M3 into a corner, it seems to flow better and have a nicer feel to it. I’ve also read similar things from the European and American publications.

    • Jordan says:

      I think you’ll find that the 4 door version of a FRONT engine vehicle will handle better than the coupe version, more often than you would think.

      • Auday says:

        I cant see any reason why the 4drs would drive better than the 2drs, the engine position should be the same relative to the center of mass and the dimensions are very similar too. The only thing I would think about would be the rigidity of the 4 door could be a bit better, but that would be a small difference that needs serious driving to show up. If there is anything that would make a difference I would think it would be the less weight of the coupe that should make it feel better.

        • racerz says:

          Actually there is a big difference. The sedan has a b pillar which makes the car much stiffer. The Coupes dont.

          There are many more 4 door BMW racecars than 2 Doors for that reason.

          Most manufacturers put a b pillar in their coupes but BMW doesnt for the looks/car lines

          • Auday says:

            yeah I already mentioned that above “The only thing I would think about would be the rigidity of the 4 door could be a bit better” but I didnt think that would make a huge difference as I assumed that the black padding on the back windows of the coupe enclose a smaller b-pillar.

          • CarGuyDad says:

            Uhmm, the coupe does have a B-pillar, what it doesn’t have a window frame around the door, just glass.

  13. viper says:

    both are great , but I think they made a mistake with sedan , they should have increased the power to 440 because its heavier vs 420hp coupe , thats how I would do , sam thing with cabrio , increase the power to 450

  14. XC says:

    I’ve always prefered the shape of coupes, but I definitely like the sedan; BMW has done a great job in that car. I saw a jerez black, beige interior one at the dealership and it was gorgeous!

  15. The Lee says:

    I’m old-fashioned. I prefer my whiskey warm, my beer dark, my women quiet and my M3s in coupe form.

    • XC says:

      In the past I would considered your comment chauvinistic and misogynous…. but today, divorced and with one kid, gosh I miss quiet women…

  16. Doug says:

    Horatiu, what did you mean about the V8 being “based on” the V10?

    • :p says:

      They took the 5 liter V10 design and chopped off 2 cylinders and a liter off.

      • Doug says:

        So they make a whole V10 engine and slice through the block, cams, crank… water and oil splashing out everywhere…!

        Seriously though, even if it is just the engine block, you still have to make cranks, cams, etc. They obviously make sure that there’s enough compatibility to sharing parts and manufacturing, but I can’t imagine that slicing the block saves more money than it wastes. Detroit did this for awhile and it didn’t make a whole lot of sense from an engineering and cost-saving perspective.

  17. :p says:

    Is there a comparison between the M3 sedan and the C63 AMG in this blog?
