Hello!
Picked up a Cx70 Preferred MHEV on Monday.
Not a stranger to Mazdas as this is my 7th one.
But it is my first ever brand new car, and first car that has an automatic transmission.
Had a 2007 Mazdaspeed 3 GT. Bought in 2012 with 25k miles. Learned how to wrench, and tune with that car. Built motor, precision 5862 turbo, auxiliary port injection, coilovers, sway bars, etc. On e48 Ethanol mix, self tuned it made 575whp/467 tq.
Had 2 2006 mazdaspeed 6. One as a beater and one I went all out with during covid to show that the MZR disi was a stout engine if you knew what you were doing. I put a pte 6266, aux port injection, and all supporting mods on an untouched bone stock car. Made 539awhp/421 tq, using a reverse tapered boost curve to keep tq in check. (The accepted limit for the stock connecting rods is roughly 400tq). And tq needs to be limited below 4000rpm as well. That setup didn't eclipse 350tq at the wheels til after 4000rpm, 400tq til 5500rpm and made peak tq at 6200 rpm. Put 25k miles at that power with over 1000 wide open throttle pulls, etc before the stock valve springs said no more and floated every valve in cyl 1 lol.
A 2007 mazdaspeed 6 with a built motor and big turbo that I parted out during covid
A 2013 mazdaspeed 3 with a bnrs4 bolt on turbo upgrade and tune.
And a 2010 mazda 3 2.5 W/ 6spd.
Needless to say, the cx70 is a big change, but fits my lifestyle now.
Initial impressions:
-mazda has come a long way in interior fit/finish/quality since 2013
-the thing handles great for its size
-the inline 6 makes beautiful sounds and is smooth
-its obvious to that the majority of cx90/70 buyers aren't car people and mostly see vehicles as appliances...but the way this car shifts (I'm assuming it has the latest software updates) doesnt seem out of the ordinary. Under normal acceleration, it is getting into 3rd gear by the time you hit 20mph...but its a short ratio transmission and when driving around normally there isn't a need to rev out further between shifts. Its also quite obvious that the majority of folks have no clue the difference between how a tq converter, wet clutch, cvt, ecvt, or dsg operate. Yeah, take off from a stop can be improved in that the 0-10mph acceleration is probably worst in class because of how Mazda has programmed 1st gear takeoff. But I imagine they are being ultra conservative with tq limits and how much they allow the clutch to slip on takeoff due to it being a brand new transmission they've never used outside of these few models the past few years.
Anyways, I'll update as I put miles on it and get to know it more!
