Peak Clutch HP and Torque look almost identical to the 800 Etec and Cat 800 HO if not one or two better, However at lower speeds the APE makes way more torque, close to 90 lbs at 4,500-5,000 tach RPM and over 100 lbs peaking at over 109, in a 4,000 rpm wide power band vs. a 1,000 rpm wide over 100 lbs power band on the Etec.
A report off another web site, Sounds like a kick ass sled. 
NO PROBLEM! I can make it.
Just in off the other site I think I'm going to get a subscription to Dynotechs web page
According to Dynotech the 162.8 isn't the right number, it's 163.7, which peaks from 10,100-10,300, still making 163+ until 10,700 but torque falls off 4-5 lbs.
The 162.8 number came from a run with a sensor issue.
Great write up on the engine, thanks
NO PROBLEM! I can make it.
* SnowGoer Magazine named the SE package the 2011 Snowmobile of the Year.
* SnowTech Magazine just named the SE the Best 4-Stroke and the base Apex shared Best Cruiser Touring Sled honors with the RS Vector GT and was a Best Trail Sled winner!
* American Snowmobiler Magazine honored it with the Best 4-Stroke Sled of the year.

Check out the sled the media can't say enough good things about! Go now.
Independent Dynotech Research testing confirms Genesis® Top Performance Engine output.
PLEASANT PRAIRIE, WI. –Yamaha engineers increased the performance of the new Apex by making a host of small updates that resulted in a new peak horsepower of 162.8 in independent Dynotech Research testing on a 2011 preproduction unit. That’s a nearly 10 percent increase over the previous-generation 4-cylinder Genesis engine. It boasts a ridiculously wide torque curve with a remarkable peak of 109.8 ft/lbs at 7300 rpm for arm-stretching acceleration. Additionally, it features the first Exhaust Ultimate Performance, or EXUP® valve found in a snowmobile.
When it comes to straightforward raw torque, the Genesis Top Performance 4-stroke engine decimates the competition, according to independent Dynotech Research dyno testing. It shows a staggering 32% midrange torque advantage over the 2011 Polaris® 800 Rush® preproduction unit and 25% more midrange torque than the early release 2011 Ski-Doo® 800 E-Tec®. Even Arctic Cat®’s production F8™ falls 17 percent short to the newest 4-cylinder Genesis 4-stroke engine in midrange torque! This 4-cylinder engine makes 100+ ft/lbs of torque for a range of 2400 rpm while the competition’s 2-strokes make 100+ ft/lbs of torque for an average range of only 500 rpm. What all this midrange torque advantage means to Yamaha Apex owners is amazing throttle response and acceleration off of a backshift and coming out of the corner.
The new 2011 Genesis Top Performance 4-cylinder engine delivers in ways two stroke competitors simply can’t. Its impressive 162.8 HP, broad torque band, and EXUP exhaust technology put 4-stroke performance at a new high. Add the Yamaha Advantage of #1

Microsoft is not the answer. Microsoft is the question. NO is the answer

Reliability and you have a sled the 2-strokes can’t touch!
If its so great? Where is the head to head with the other four strokes.
Its been know that four stokes produce more torque than a 2 for thirty years..... This compasions doen't show me anything new from those reports 30 years ago.. Except a longer RPM curve.
Yawn...
