The first comparison driving test involving the new BMW M3 GTS has been published by German magazine AutoBild. The opponent? Porsche’s own star, the 911 GT3 RS.

Before the showdown, AutoBild spent some time with the two cars, examining their strengths and weaknesses. The GTS impressed the editor Joerg Maltzan, not only because of his aggressive Orange Fire painting, but also because of the 8,000 rpm redline found in the GTS.

Moving onto the Porsche, the magazine was fond of the exterior visual elements, an aggressive front spoiler and a large, stationary rear wing, and last but not least, the large 19-inch wheels.

BMW’s elaborate GTS suspension and stiff body have also impressed them: “rich, peaceful, neutral and precise steering response. Even without electronic assistance, [the M3 GTS] remains at a manageable level.”

On the other hand, the Porsche 911 GT3 RS delivered some great braking performance, due to its nearly 9,000 euros ceramic brake system.

The GTS is not only larger, but also more difficult to handle. The car offers 450 horsepower at 1538 kg curb weight (factory claim 1530 kg), while the Porsche with the same 450 horsepower only weighs 1400 kg (1370 factory specification).  Whether during acceleration, braking or cornering, the German editor continues to point out the higher weight of the GTS.

Performance wise, the Porsche accelerates from standstill to 100 km/hr in 3.7 seconds, while the M3 GTS stops the clock at 4.6 seconds. The gap becomes wider at 200 km/hr where the Porsche is 2.0 seconds faster.

Unofficial numbers show a far smaller gap between the two cars, as outlined below by AutoBild:

Curb weight work: 1.530 kg
Curb weight car picture: 1538 kg
Acceleration 0-100 km / h manufacturer: 4,4 s
Acceleration 0-100 km / h Auto Bild: 4.6 s
Vmax work: 305 km / h
Vmax Auto Bild: 305 km / h

Porsche 911 GT3 RS
Curb weight work: 1.370 kg
Curb weight car image: 1.400 kg
Acceleration 0-100 km / h manufacturer: 4,0 s
Acceleration 0-100 km / h Auto Bild: 3.7 s
Vmax work: 310 km / h
Vmax Auto Bild: 330 km / h

A our sister-magazine BimmerToday points out, there are still many unknown variables in this test drive, from the factory prepared cars for the drive to the performance work done to the 911.

    Why would we insult ourself with this type of out of balance comparison. We all love M3 and we all know M3 is great but 911 GT3 is the NEXT LEVEL….GT-R level, man.
    I hate people call me a fanboy of BMW but I guess this is why they think we are!

  2. Doug says:

    I think the problem is that comparing the specs doesn’t do justice to what these particular cars are about – handling. You get the usual subjective stuff about it, but I can’t help wishing that there were standardized measurements of handling aspects. The car companies have those — they have to, because they would not have a clear goal to work with their engineers on. But we need something that can quantify the handling performance in a few numbers..

    Yaw acceleration? Dive/squat/roll rate and travel? Suspension average damping factor and normal frequency?

  3. Doug says:

    More to the point though: although the difference in weight was a significant to Joerg, it may be more important how that weight was distributed; the porsche has a center of gravity that’s far lower and closer to the turning axis.

    Going to await the Nurburgring times before passing judgement, but BMW were begging for a GT3 RS comparison by calling this the M3 GTS. They could have escaped some rivalry perhaps by naming it and making it more CSL-like.

    I suppose it’s inevitable now that the M3 GTS will sit in the shadow of the GT3 RS’s specs unless it puts out better lap times.

    • A Porsche GT3 and a BMW M3 are marketed to two very different segments and price points so I would expect the M3 to perform slightly less than the GT3 given what you’re paying for each.

      • 1mc says:

        They should be as you marketed towards different segments – but I’m not sure that’s been communicated. If I want a weekend car for the track that’s ready off the shelf, and have 100k to spend I’d end up comparing the two:

        GT3 RS
        £106,870.00 incl. VAT

        M3 GTS
        £103,000 incl. VAT unconfirmed blogosphere estimate

        Maybe you’re more savvy and can break down why consumers won’t compared these two cars though!

          In Europe (continent) price difference is much bigger. In my country GT3 RS costs 181000 euro, price of M3 GTS was 115000 euro. The problem is that someone just counted the price by taking euro-pound rate and deliever the result by changing price in euro on price in pounds (according to the rate). That’s fallacious way of estimating prices for given coutry since much more factors play role here. Neighter UK prices nor US prices are counted in such simple way. I wonder why people constantly forget aobut it when they talk about GTS.

  5. viper says:

    a stupid comparison. the GT3 is untouchable

  6. ferrarifan says:

    the fact that it’s being compared to the RS means something in itself.. it does not need to beat every single car, i know people here wants to but you are missing the point.

  7. fadi says:

    i am surprised why the M3 weights 1530kg. if i was BMW CEO I would build this car of complete carbon fiber even if i am going to pay from my own pocket. numbers are not comparable…………………what a shame. i think that BMW needs a crazy man like Carlos Ghosn…….this CEO is sales man not more.

  8. bob191 says:

    guys from such comparision wt they mean is that even the upper leveled car is jst a liltle btr frm the m3 …. even though the gts is not a gd competitior for the m3 the m3 is jst 2 second slower in gap….

  9. Artmic says:

    The outcome was predictable, the Porsche will cream the M3. Even a Carrera S will win against an M3. I drove the Carrera S a few months ago, after driving an M3, and the difference was amazing to me, the Porsche felt like it was made out of feathers compared to the M3.

    • wazon8 says:

      You’re badly wrong. Start with checking Carrera S data: 7:50 at Nurburgring says everything about its performance. Since according to reports, M3 GTS reached 7:40 there is huge gap between it and Carrera S. The last one is slightly better than M3 CSL e46. You simply overestimate Carrera S and underestimate M3 GTS. Moreover, you talk as if GTS was nothing more than standard M3. BTW, what did you expect when you compared coupe for four adult persons with two regular sits coupe?

    AutoBild = VW propaganda magazine

    Everybody in Europe knows it.

  11. Pierre says:

    The Nissan GTR is not only a compelling M3 GTS + Porsche GT3 beater, it is also MUCH cheaper!!!

  12. JMLBMW says:

    It’s simple why the Porsche beats the BMW… “Power to weight” End of story! Not to mention that the M3 GTS is ugly… Orange… what’s this… the 70’s? Get some class BMW and upgrade the cheap plastic interior! Car and Driver hammered BMW for it’s cheap interior on the M3! I agree!

  13. 1mc says:

    Track cars are usually quite loud looking or have some sort of livery. Look at the GT3 RS paint jobs – it screams ‘I’m a track car’. Same as the Inca Orange on this GTS, it’s a loud colour for the track and to be fair, it’s a cracking colour too with stacks of presence. You will know when the GTS is up your rear end and exactly what car it is without needing a second glance. If you cant express yourself on the track, then where can you?

    As a side note, I’d love the BMW Art Car vinyl job on a track car. I think it looks absolutely class.
