• BMW releases M3 DTM concept car technical specifications as well as statistics of BMW Motorsport DTM racing history

      You should know by now BMW is returning to DTM racing. They will be racing an M3 which will have a 4.0 liter V8 (coincidence the road car features the same style of motor? Nope) which will be putting out about 480 horsepower depending on the restrictors used. BMW last raced in DTM from 1984-1992. The last victory coming in October, 1992 on the Hockenheim with an E30 M3 Evo. Two decades was far too long of a break, we look forward to seeing the new M3 DTM car in action.

        So much for DTM changing the regulations so the cars resemble more of a road car.

        This is basically a completely one-off car that has zero to do with any production M3.

        It has a high revving 4.0 V8, close enough Click here to enlarge

        But yes, the measures were all for cost cutting so it isn't the same as it once was. The ALMS cars can probably be argued to be closer to their street variants.

        ALMS are much closer, but even those are far from road cars.

        All the DTM cars are 4.0L, that is the maxium displacement allowed. DTM regulations stipulate V8 engines with a 90-degree vee-angle, a maximum capacity of four litres and maximum four valves per cylinder. A DTM engine delivers about 340 kw (470 hp).

        This car is as close to a M3 as a Nascar is to a Monte Carlo.

        I would say this is closer since the M3 engine displacement and type does mimic it. When was the last time a Monte Carlo had a carbureted V8?

        Audi and Benz both run a 4.0L V8. Does Audi have a V8 in the A4/S4? This DTM car literally has no relation to the M3. It just has an M3-ish type body.

        It is really just a coincidence that the current M3 has the same displacement as the DTM regulations. Those regulations have been in place for some time.

        Audi, Benz, and BMW will be very similar in construction, there is only so much they are allowed to do. Only real difference is the exterior body and aero package.

        Side note: Nascar is actually going to fuel injection next year.

        I do not disagree with you but this IS closer than a NASCAR is to a Monte Carlo.

        I don't think it is coincidence. BMW knew they would get back to DTM, knew the M3 would get a V8, it all came together exactly as it should. The M3 could have had more displacement to begin with.

        But the point on the carburetor stands Click here to enlarge

        No, I think it had a lot to do with the S85 being 5.0L.

        Keep in mind, they will be racing the next generation 3-series body soon. The DTM car will still have a 4.0L, while the next 3-series or M3 will not have a V8.

        Side note: Audi is switching to the A5 for 2012 DTM season.

        But the DTM car will have the E92 body for some time.

        Audi and Benz have switched to current body styles in the past very quickly. I believe BMW will follow suit. The companies want the exterior of the car to represent was is being driven on the road.

        Audi is switching to the facelifted A5 body, it hasn't even hit the road yet.

        I give this body and aero package maximum two seasons.

        Oh yeah, thought you like to know BMW was hit with a performance adjustment for ALMS. This was after their last win in Lime Rock. The M3 must compete with two restrictors sized 29.4mm (-.4mm).

        I think they will be fine. It really actually brings them inline with the ACO regulations in europe. For some reason ALMS has been letting them run a bigger restrictor.

        They also have a larger diffuser and they are allowed to run the rear wing higher in ALMS. I don't really understand why ALMS lets them run a different setup than Eurpean Le Mans regulations.

        I'm not really sure either but does that go for all the teams?

        Nope, just BMW RLL.

        Weird, wonder why that is. If the other teams go under Euro rules then so should BMW.
