8.1L GM Vortec 8100 Still the King of Gas Motor Home Power</span>

UNION CITY, IN. -- The latest test data is in, and if there was ever any doubt, the numbers have erased it. The Big Block GM Vortec 8100 is still the finest Class A gas motor home engine on the road.

"Superior displacement and engineering is still the key,"� said John Buttrey, Workhorse vice president of engineering for Workhorse. "The Big-Block Chevy Vortec remains best in class in all the areas retail customers really care about."�

Recent tests showed a Vortec-powered motor home quicker in 40 to 60 mph acceleration, important in merging onto an Interstate, and in 50 to 70 mph acceleration for highway passing. In the 40-60 mph test, it took a motor home on Workhorse's W22 Vortec-powered chassis 14.3 seconds versus 16 seconds for the same model motor home on Ford's F53 chassis powered by the new Triton engine at the same 22,000 lb. GVWR. In the 50 to 70 mph test, the Vortec-powered motor home performed even better, reaching 70 mph in 20.2 seconds versus 22.8 seconds for the Triton-powered model.

Also, in a 0 to 60 mph acceleration test towing a 4,000 lb trailer, the Vortec-powered coach came out significantly ahead, clocking 31.5 seconds versus 34.1 seconds for the Triton-powered vehicle. And, this clearly superior performance was achieved with better gas mileage: 8.8 mpg for the Vortec versus 8.5 mpg for the new Triton.

Finally, the big block Vortec-powered motor home performed all of these feats at lower rpm and ran significantly quieter, measuring 3 decibels lower than the Triton-powered coach. "The Ford unit peaked at 47 percent higher sound pressure than the Vortec during full throttle 0 to 60 runs,"� said Buttrey.

That's no accident, but a great engineering combination, said Buttrey. He, explained, "Horsepower at the fly-wheel is what is typically quoted on engine power. We at Workhorse understand that the key driver of performance is how much of the horsepower actually gets to the rear wheels. That's where the combination of Workhorse, Vortec and Allison makes a real difference."�

"We want our customers to know that they can safely use their motor home as they intended. They can get up to speed and pass slower moving vehicles without any worries,"� said Bob Wert, vice president of sales, marketing and product planning for Workhorse. "The Vortec, coupled with the Allison transmission, provides the bragging rights for the best performing gas motor home out there."�

"Power and performance is what Workhorse is known for, and these new facts cement that reputation further. That the top ten RV dealers in the country averaged 79 percent of their Class A gas motor home sales with a Workhorse chassis shows that customers want that kind of value."�

Specializing in the manufacture of chassis for motor homes, walk-in trucks and buses, as well as integrated walk-in trucks, Workhorse Custom Chassis is ISO 9001 certified and considered a leader in the motor home and walk-in truck industries.

Bravo

From a "seat-of-the-pants" perspective I still can't get over how powerful and smooth the Vortec/Allison combination is in my coach.

On a recent trip to PA, for the iRV2 National Rally, I logged nearly 1,000 miles on my Workhorse. There were plenty of big hills along the way and I was on a tear! (Not trying to break any fuel mileage records anyway ) I was passing EVERYTHING that wasn't keeping up with traffic. I passed tractor trailers, diesel pushers and CARS going uphill! There were even a few times I'd slow down a bit while cruising in the RH lane to let a soccer mom merge in driving a Volvo or minivan, but they chicken out and slow down so I just "Stand on it" and the coach takes off like a shot! I never would have imagined it before I owned this MH. Now, granted I wasn't loaded to capacity, but I was carrying enough stuff to sustain us for a week.

This report by DriVer which points out the facts about the 8100 Vortec being a powerhouse couldn't be any more accurate and comes as no surprise to me. If you want a truly powerful yet smooth, efficient and quiet powertrain for your next gasser I highly recommend a Workhorse Custom Chassis be underneath it.

Thanks for the info. DriVer.

Driver:

I asume this is with the new V10 of 364 hp vs the v8 at 340 hp. I just read the hp rating in the magazine on the V10. Good results you have offered without a doubt. But some are going to ask. Going up the grade in Northern California last week, I had no problem passing a new Triton V10 - we talked about it in the rest stop at the top. He was dissapointed.
