STARTING AND OPERATING 285 Ramp Travel Index (RTI) The ramp travel index is the distance, in inches, that you can drive your vehicle with one wheel on a 20-degree ramp without lifting any other wheel off the ground. This distance up the ramp divided by the wheelbase of the vehicle and multiplied by 1,000 is the RTI. This vehicle has an RTI of 655, which means you can articulate one front wheel 32 inches in the air while the other three wheels remain in contact with the ground. High Mobility Characteristics This vehicle has high off-road mobility characteristics with an approach angle A= 35 degrees, a break-over angle B= 25.5 degrees, a running ground clearance C= 14.5 inches, a departure angle D= 26.5 degrees, an axle to ground clearance E= 8.4 inches front/E= 8.25 rear and has a ramp travel index (with the smart bar in off-road mode) of 655. Also, it has a grade-ability of a 60% (31 degree) slope. 5
