Have you decided against the super econodyne option? Mack has alreay done the homework if you go with the Super Econodyne Pinnacle and you should get the best possible mpg with that set up. If your not set on the M Drive and want to get the best of both worlds go with a Mack 318LR or 313LR, or even an Eaton 18 speed transmission there youll get a lower low gear to get you moving near gross so you can still run the higher rear gears and when you pop it into OD your gonna really drop rpm. If you were running closer to 40,000-50,000# all the time a higher low wont matter as much so the direct would give you decent service.
Running near gross you will appreciate the lower 1st gear with an overdrive transmission and its unlikely youll ever notice much difference in mileage out of a controlled test setting.
#2016 mack pinnacle specs drivers
Personally i never had a problem with the mDrive/iShift, and never had it choose a wrong gear on me - but then again, I drive on pavement and don't often go above 80k. All of our other drivers seem to prefer the 505hp Macks to our Cascadias - and they pull a lot of 90,000lb loads (139k gross).īTW, I prefer the (standard?) horizontal arrangement, which should give you a little more dash space to play with.įor what it's worth, i'm just a company driver, so take it all with a grain of salt.Well you get more rear wheel torque with direct drive, any overdrive reduces rear wheel torque and so therefore you have a shot of best mpg with direct but the higher gears are easier to damage and you lose bottom end takeoff. I haven't heard any complaints from others. But at 6' I found the reach to be comfortable and natural - no harder than reaching for a stick.
#2016 mack pinnacle specs manual
Yes, the only way to switch to manual mode is through the dash pad. Driving through it! The I90, I75 and I71 are flat,flat,flat.Ģ. Most I know are not too mindful of the boss's money.ġ. Interesting to hear a teamster talk about trucking efficiently. It is my plan to grow eventually anyhow and a Titan would be a good second truck. I can always buy another truck down the road for the heavier hauls.
I am pretty sure I am leaning toward a CHU rawhide edition 13-18 speed with e the MP-8 505.
#2016 mack pinnacle specs plus
I mean the added hp would be nice if I ever decide to step up my weights over 125k lbs but I need to be able to get into construction sites and many can be tight, plus some city streets where the sites are located can also be difficult to navigate with a truck that turns like a battleship. I guess my biggest concern is the turning radius of the Titan. Question though about the Mdrive, Is the only way to manually shift it from the pad all the way to the far right on the dash or is it like the Allison 12 speeds where they have paddle shifters on the wheel? I would think reaching across the dash would become a danger. I too am old school and I think I will stick with either the 13 or 18 speed trans. I have always driven manual trucks wether it be dump trucks or lowboys. I am not sure I will like not being able to control my gears.
I don't know where people get that Ohio is flat. Well in southern Ohio where a lot of the work is it is not very flat, in fact some routes can get pretty scetchy, ( steep grades 90 degree turns at the bottom of the grades, etc. I guess it depends how much these things cost. When I recently chatted with a Mack salesman, he recommended not getting the mDrive HD for "such low weights." I can't see how it would hurt. BTW, I used to pull 125,000 daily with a 400hp c15 Cat. Only if you were in the mountains every day would I suggest a 500+hp 16L. Hint: most of the Ontario Macks are CXU's 505/1850 mp8's with 14,600 + 46,000 axles and suspensions, 18spd or mDrive, and often geared around 3.73, 3.91 or even 4.11 (although I've only seen the latter on Western trucks.) By law we all have speed governors set at 65mph.
Why don't you look at some Canadian dealers sites and see how they spec their trucks? I see you're in Ohio, which is pretty flat: Southern Ontario would be the most similar. Geared and spec'd right they do just fine. Most Fleets up here hauling up to 135,000 lbs gross order CHU or CXU MP8 505hp.
