Another glaring example of Volvo's refusing to give Mack the tools to be competitive... In Europe the MP10 is available in Euro 6 compliant ratings up to 750 horsepower. Volvo could turn lose the MP10 and let Mack build the Titan with the options like big sleepers that customers want... A 750 horsepower Titan with sleeper options, etc. would chase Paccar et al right out of the high GCW markets like Michigan, South Dakota, the intermountain states, and Canada. But Nooo! Seems like Volvo wants Mack to fail...

One uses EGR and one does not. Cant cool that much HP with EGR reliably I suppose.

Then an EGR delete should be straightforward if one could lay their hands on the high hp AU software

Fun is what they fine you for!

Sales of the Volvo FH16 Euro 6 are now under way. With up to 750 hp and 3550 Nm of torque, it retains its position as the strongest truck in the world. The first Euro 6 versions of the Volvo FH16 will be delivered in early June.

The Volvo FH16 is ideal as a tractor for heavy rigs and timber haulers, and also for fast transport assignments characterised by exceptional demands on driveability and productivity. Now the world's most powerful series-produced truck is available with a new generation of 16-litre engines producing a choice of 750, 650 and 550 hp respectively, all conforming to Euro 6. In addition to lower emissions, the new engines also offer higher torque at low revs, a more powerful engine brake, and quieter operation.

"The Volvo FH16 with Euro 6 engine has the same high reliability, the same fuel consumption and the same power as before. But now the driver has access to maximum torque from just 900 or 950 revs a minute depending on engine version. This improved torque curve also allows customers to choose a faster rear axle ratio for best fuel efficiency," says Astrid Drewsen, Product Manager, Drivelines at Volvo Trucks.

All the engines are equipped with Volvo's automated transmission, I-Shift. The 550 hp version is optionally available with a manual gearbox. All the engine versions can be specified with Volvo's VEB+ engine brake. Maximum braking effect has been raised from 425 to 470 kW at 2200 revs a minute, further improving safety and reducing wear on the wheel brakes.

In order to deliver the low NOx emissions required by Euro 6, Volvo's engineers have used cooled EGR (Exhaust Gas Recirculation) in combination with an updated system for after-treatment of exhaust gases. A new dual-stage turbo helps power the EGR loop and also delivers the high power outputs. The engine features pilot injection. This means that a small amount of fuel is pre-injected into the cylinder, creating more uniform pressure build-up and a softer engine note.

Not to change the topic, but the special anniversary Granite pickup that is in or just out of production is an 800 hp 2800 ft/lbs MP8. From what I heard it's just a MP8 with a MP10 turbo (special manifold) and programming. This Granite is suppose to meet all the emissions standards. It has DPF and DEF. I think the different hp rating are just achieved by programming and maybe some small component changes.

Another possiblity is that Volvo's much trumpeted automated manual transmission can't handle more than 605 HP for longer than the 3 year/300,000 mile warranty they give you on a "vocational" truck like the Titan?

im pretty sure in oz the 685 hp mp10 is only available with the m drive . as far as the us market titan on paper it has has the most power of any engine available in north america 605 hp 2060 torque. cummins and detroit are 600 hp with 2050 max .

Engineers are well aware, you take any engine (MP10 being the subject today) and turn it up for a higher torque and HP rating it's going to be strong but it will wear out faster. It's science. When engines are rated, companies consider engine mean life at the ratings they release to the customer. Engines have to use or produce more energy per cylinder to put it out at the end of the crank shaft. (energy isn't free). With tweeking things you can get lots of power out of almost an engine. 1000hp out of a 5.9 Cummins exists but how long does it last pulling heavy loads??? It's a balance of energy produced versus resistance of load etc. Every internal part must be able to handle the stress over the life of the trucks life expectancy. I'm always wondering why they punch out the Euro truck engines when they haul some of the lightest gross weights? Maybe they know they will last doing less work?

Lower ratings on engines with robust internal parts usually means they will last longer and should reduce warranty claims. EGR and other emissions on engines do effect engine performance. Euro engines don't use egr.

Actually the world's heaviest weights are in Australia, with up to 150 metric tons possible with road trains in the outback and up to 85 tons routine with B triples and such. Weights are actually heavier in parts of the US than Europe, South Dakota allows around 76 tons on 17 axles and Michigan around 75 tons on 11 axles, much higher than Sweden's 60 ton limit, which will probably go up to 75. The difference is primarily in use patterns and ownership cycles, as European trucks will only cover a million kilometers in 10 years before the owners trade them in and they get exported to the third world, while US owners often keep their trucks for nearly twice that before they get traded off and used by a farmer, construction company, etc. for another 10 years or more. Thus when you're making an automated manual transmission of suspect durability like Volvo, it makes sense to cut back the engine's output so it and the suspect transmission can at least survive 'til the warranty expires.

In Australia we are one emissions step behind the US which allows the mp10 to be scr only. Set at 685hp with 2300lb-ft torque, the mdrive is the only gearbox rated to handle the torque. A 600hp (2065lb-ft) setting is available with a road ranger 18 speed. The mp8 here is also scr only and can be rated at 535hp with 1925lb-ft torque. Both engines run a wastegated turbo.

Sweden allows up to 64 metric tonnes on 6 or 7 axles most of Europe is 44 tonnes. Some countries allow 50 tonnes. I'm guessing in Europe the rivalry between competing truck and engine builders are the reason the hp is so high. Seems like north america is stuck at the 600 hp mark . cat had a 625 for a few years before they got out.

"Jack" Mack is a GU MP-8 with an MP-10 turbo which puts out 800 hp with 2800 ft/lbs of torque. Unfortunately it's not a production engine. It's a one off made as a "show" truck. I'm wondering why Mack doesn't offer it. If an MP-8 can do 800 hp, there's no telling how much can be squeezed out of an MP-10. Though the torque curve is pretty much from 0-2,800 but with that kind of power, why the hell not.!

My mp10 likes to be ran to 1400rpm. It only see's 1800 when down shifting.

Does your motor use urea?

I still haven't caught up on the emissions stuff.

Fun is what they fine you for!

My name is Bob Buckman sir,. . . and I hate truckers.

Someone was telling me the MP10 was capable of up to 1000hp and still be ran over the road...

I was just curious about the extra power US-605 AU-685 didn't the AU-E9V8 have more power?

There's an o/o that runs for the mill I was working at with a pair of KW with 6NZ cats that were dyno tuned to 750HP and 1000HP....hes been running them like that for years. The red KW (1000HP) has been "turned down" because of tearing up drivelines. Anyone familiar with the area: Both can pull the "hamilton mountain" NB (HWY6 North) @ +/- 60,000KG in high range. High power OTR can be done, just gotta watch what you're doing

Lack of planning on your part does not constitute an emergency on my part....
