At the LA Auto Show, Mazda unveiled the next CX-9 with one notable power aspect: a turbocharged 2.5 SkyActiv motor. Naturally, we couldn’t help but speculate about what this means for the new 2017 Mazdaspeed 3. What makes this motor special is that Mazda has officially tipped its hat at a factory turbo motor, which could be the basis for the next Mazdaspeed 3 motor.
It doesn’t look like much on the front side, but there are some promising aspects. With a center mounted throttle body, getting even airflow to all of the cylinders is an easier task compared to the last turbocharged motor Mazda offered in the Mazdaspeed 3/6 and CX-7.
The official power numbers are 250 HP on premium fuel and 310 torque. Mazda said you could run the engine on lower grade fuel resulting in only a decrease in HP (not torque) due to the design of the dynamic pressure turbocharger, which is used on this new motor.
Looking back at the CX-7, Mazda offered it with a smaller turbocharger to generate more torque at the expense of top end power. I expect to see a larger turbocharger fitted to the 2017 Mazdaspeed 3, which will get the stock power levels over 300 to start with.
Was at the LA auto show last week and those are the correct HP and Torque numbers. The construction of the turbo sounds interesting. It also puts out 17.4 psi. I am sure that will be the motor going in the 2017 MS3 but it will need to be pumped up to over 300hp to match the new RS from Ford. I asked the factory rep about putting that motor in the Mazda 6 and his answer was that the 6 grand touring is only an “i” and not an “s” so maybe if an “s” comes out it will have that motor in it. Since I have a 2008 400hp MS3 and a 2014 Mazda 6 grand touring. Does this mean I need to by 2 new cars????
can’t wait to see the numbers on the motor
How about fitting it in the Miata ? That would be a Mazdaspeed I would put money down for right now. Don’t get me wrong I would like to see it in a speed 3 also but it must out do the Ford RS. I saw the Ford at the LA auto show too and that is a nice ride with some impressive numbers and $8K less then the new STI for that matter ($34K vs $42K). That s also pricing me out of the market.
Mazda says the engines are scaled so overall it would be too big. I am thinking it can be done but until we get one of the engines in hand we would not confirm or deny.
Another thing to consider is a new tech they used for the turbo motor on the new CX-5. It feeds air to keep the spool going to reduce turbo lag between shifts and low rpms this will keep torque up at those low rpms! I guess this makes more sense for a larger more towing type of vehicle like the CX-9. I wonder if this will be included with the speed3? Boost numbers and the whole power band will be much smoother. Another thing I am assuming because of the skyactive compression numbers, higher boost pressure at low rpms won’t be as damaging as it is for the older MZR engines 07-13. Unless I am completely wrong?.
Corksport! keep us updated we are all counting on you!!
I have speed 3 blue sup up utmost fully intercooler downpipe my friend Cody bountiful mazda I was talking to a dealer on the speed3 he said cx9 thereso talk on 2.7 turbo engine on the speed 3 no official word but on the grapevine heard there considering possible a v6 engine in a 3 platform natural aspirated or turbo still up in air most likely I think will new turbo 2.5 340 hp awd car
