    Default Skyactiv-D Mazda 6 debuts at 2013 Daytona 24 hrs

    Turbo diesel I4 (edited). I think this thing is really cool. Love the vader/NASCAR look.

    i have/track the old MS6, theyre(mazda community) hoping for a newer edition. W/more power. that looks pretty big, which was always the cars main flaw IMO, i wonder how that actually handles?

    My understanding is that it is the same tube frame chassis as the RX8 with a new engine and body.

    Mine, too. So the car should be pretty good out of the box if the motor didn't destroy the balance.

    Anybody want to bet after its first race it gets a restrictor or boost limit?
    If nothing happens and there is no one around why did it not happen?

    i know theyre talking about a coupe, hopefully to replace/repair the damage from the Rx.. overall a very nice agressive look.

    Digging the agressiveness of that front end. Nice shape and sense of motion with the grill and lights flowing to the fenders.

    Didn't the GT class RX-8s have a 3 rotor? This has an aluminum block so I doubt it weighs much more than the rotary it replaces. Might even be lighter. I'm pretty sure it will have more torque.

    Guessing the Diesel engine is heavier, especially with the turbos and plumbing.

    I don't see how the diesel could be lighter. Rods, pistons and crankshafts in diesels have to be pretty beefy. Rotaries are designed for rpm, so lightness is a must.

    I never thought rotaries were particularly light given their displacement.

    I thought that a 13b weighed more than a Miata 1.8 with an iron block.
    I could be wrong, it happens a lot.

    It is difficult to measure rotary displacement properly. By most guesstimate work, the 13B is a 2.6L and the 20B is a 4.0L.

    Unless the 20B the RX8 used had aluminum front, rear and mid housings, the engine is not light... they are normally made out of cast iron and are seriously heavy mofos.
    The part that makes rotaries RPM happy is that the inherent problem of a piston engine is eliminated.
    They don't change direction like a reciprocating engine, so the limiting factors normal piston engines have are just not there... no valves, rods or pistons.
    Of course, the rotaries have to rely on proper seal between the rotors and the housings which introduces a whole other set of problems.
    Most car makers that have experimented with rotaries have given up on making it happen despite the advantages because the downsides outweigh them.
    Mazda is the only one out there that keeps playing with the rotaries, most likely to keep the fanboys happy.

    Mazda owns the patent for the Wankel rotary, which is another reason no other car company makes them.

    That is incorrect, as the rotary engine was originally patented by NSU and I even recall seeing it stamped (or was it cast?) on old Mazda housings.
    Since NSU patented their share in the 50's, those patents have expired a long time ago.
    Other manufacturers spent some time and money playing with rotaries too, Mercedes, Audi and GM are noted.
    Mazda added their fair share of patents throughout the development that they added to the platform, but even the basic design of their latest commercially available rotary (13B-MSP, AKA Renesis) isn't specifically patented for the RX8 production since the side port design was patented in the 60's.
