@dalekrueger Basically the high torque rise, or 'Maxidyne' concept is all about getting the turbo to spool up and produce lots of boost at a low engine RPM, and then not over-boosting at high RPM...and building an engine tough enough to withstand this high output at low RPM. All truck engine manufacturers are following this concept today, but Mack was the first. This high torque at low RPM is the KEY to good fuel mileage and also makes for less shifting.
@dalekrueger A relatively long stroke is definitely a factor in producing higher torque at lower RPM, but the real key is producing near-constant cylinder pressure for the entire duration of the stroke.
@arkansastrash320 Theyre built in the US, but not sure who owns the company. Theres a plant in Macungie Penn. The side of our engine blocks are stamped 'Renault' - which is from France.
@jeepman65 Well renault has allways been good quality.Its got to the point where its not american to be american your more amerrican if your a foreighner no joke..
@arkansastrash320 They're still American made, and EVERY COMPONENT IS MADE IN AMERICA AS WELL unlike Peterbilt (Canadian parts), Kenworth (Canadian parts), Freightliner (now made in Mexico)
I've driven several different Mack Models (mostly older) and they're the best. We used to call them "idiot proof". If you can break a Mack you've got no business driving whatsoever.
When i look back on Mack Trucks, i feel pride, WHY? Because Mack Trucks made the small BIG It made the weak, STRONG. The east coast of america was built with a lot of help from Mack Trucks. There are some who make fun of Mack Trucks, i say learn to like then, for if you live in the eastern side of the USA, then Mack Trucks helped your dad, your grand dad, and great grand dad to be BIG and STRONG. Prove me wrong, it's fact, Mack Trucks help make the USA the greatest nation on earth. PERIOD!..
Good score with this video! I miss those old DM models....they were just perfect for roll off! Plain and simple truck......made tight spots a real breeze!!!!!!!!!
Amazing to find all that info in the video. Mack certainly has a well deserved great reputation.

I'd rather put a 50 year old Mack to work for my business than many new trucks made today.

So thats how the bulldog became their mascot. It makes sense, bulldogs are tough, loyal, dependable, and strong, and thats a Mack!
