1. The higher output, 145 amp alternator meets the electrical demand for today's motor homes.

2. The Electronic Throttle Control replaces the cable between the accelerator pedal and the throttle with an electronic communications system. Far more accurate than a cable connection, it provides increased performance and reduces emissions.

3. Oil and filter changes are the only scheduled engine maintenance required in the first 100,000 miles.

4. Dex Cool engine coolant gives you a long five year or 150,000 mile service life.

5. Individual coils at each spark plug provide 50 percent more spark for better engine performance and improved gas mileage.

5. 5 Platinum tip spark plugs have an estimated service interval of 100, 000 miles.

6. High flow and increased performance cast stainless steel exhaust manifolds withstand greater heat for longer life.

7. The sturdy long-life accessory drive belt has a life expectancy of 150,000 miles.

     Now you can move to the head of the pack. And stay there. Powered by the brawny GM Vortec™ 8100, 8.1 liter engine, Workhorse gas platforms free you up to pass RVs and trucks on mountain roads. Overtake with new agility. Merge into busy interstates with confidence and tow to your heart’s content. You also get better gas mileage and a surprisingly quiet cabin. So turn on a favorite CD. And keep V10s in your rearview mirrors.

     Packing 340 hp and 455 lb.-ft. of torque, the GM Vortec 8100 is the biggest gas RV engine ever built. And only Workhorse has it. In independent tests, the W Series platform easily outperformed a V10 chassis.

With the GM Vortec 8100, Workhorse platforms take command of the passing lane.

     What is horsepower and torque? Put simply - torque is what does the actual work and horsepower is how FAST we do the work. To take this a step further - acceleration depends on the engine's ability to generate torque at more than just 1rpm. The fatter the torque curve, the faster you can accelerate, because you have more RPMs to work with.
     How does this equate to performance?
To most, performance is how quickly you can accelerate and maintain speed in any given situation. We maximize performance through the ability to put the torque to the ground. We maximize torque to the ground through gearing and engine/transmission calibration, and keeping the engine in the rpm range where the engine generates the most ground speed for a given torque value.

Let's talk numbers

     Independent testing of 2005 Workhorse vs 2006 Ford, using identical motor homes down to the fabrics, showed the following:

  Workhorse (sec.) Ford
(sec.)		 Improvement
0-60 Towing 31.5 34.1 8,3%
40-60 Towing 14.3 16.0 11.8%
50-70 passing 20.2 22.8 12.9%

Fuel Economy

Fuel And Economy   Workhorse Ford Improvement
Fuel Mileage (mpg) 8.8 8.5 3.5%
Noise 80db 83db 3db

Note: All comparisons were performed with a model year 2006 Ford and a model year 2005 Workhorse, using identical coaches.
