An electric vehicle is disclosed having a frame, a plurality of ground engaging members, an electric motor, a front drive system, and a rear drive system. The electric motor is configured to provide power to at least a portion of the ground engaging members. The vehicle also comprises a plurality of batteries, an electronic controller, and a drive mode input. The drive mode input is operatively coupled to the electronic controller. The electronic controller operates the electric vehicle in one of a plurality of drive modes based on the drive mode input. In a first drive mode, the electronic controller specifies a first amount of motor braking to be applied by the electric motor, and in a second drive mode, the electronic controller specifies a second amount of motor braking to be applied by the electric motor. The second amount differs from the first amount.

1. An electric vehicle, comprising: a frame having front and rear ends;a plurality of ground engaging members supporting the frame, the plurality of ground engaging members including a first group positioned adjacent the frame front end and a second group positioned adjacent the frame rear end;an electric motor supported by the frame;a front drive system supported by the frame and positioned adjacent the frame front end, the front drive system operatively coupled to the electric motor and to the first group of ground engaging members, the electric motor providing power to at least one of the first group of ground engaging members;a rear drive system supported by the frame and positioned adjacent the frame rear end, the rear drive system being operatively coupled to the electric motor and to the second group of ground engaging members, the electric motor providing power to at least one of the second group of ground engaging members;a plurality of batteries supported by the frame;an electronic controller which controls a provision of power from the plurality of batteries to the electric motor; anda drive mode input operatively coupled to the electronic controller, the electronic controller operating the electric vehicle in one of a plurality of drive modes based on the drive mode input, wherein in a first drive mode the electronic controller specifies a first amount of motor braking to be applied by the electric motor and in a second drive mode the electronic controller specifies a second amount of motor braking to be applied by the electric motor, the second amount differing from the first amount. 2. The electric vehicle of claim 1, wherein parameters for first drive mode and parameters for the second drive mode are stored in a memory accessible by the electronic controller. 3. The electric vehicle of claim 2, wherein the parameters for the first drive mode are downloaded from a remote device operatively coupled to the electronic controller. 4. The electric vehicle of claim 1, wherein the first drive mode is a company mode which is specified by an owner of the electric vehicle. 5. The electric vehicle of claim 1, further comprising a prop shaft coupling the electric motor to the front drive system, the prop shaft extending through a longitudinal opening in the plurality of batteries. 6. The electric vehicle of claim 1, wherein at least one of the first amount of motor braking and the second amount of motor braking vary based on an rpm of the vehicle. 7. The electric vehicle of claim 1, wherein at least one of the first amount of motor braking and the second amount of motor braking are applied when a current speed of the electric vehicle exceeds a desired speed of the electric vehicle. 8. An electric vehicle, comprising: a frame having front and rear ends;a plurality of ground engaging members supporting the frame, the plurality of ground engaging members including a first group positioned adjacent the frame front end and a second group positioned adjacent the frame rear end;an electric motor supported by the frame;a front drive system supported by the frame and positioned adjacent the frame front end, the front drive system operatively coupled to the electric motor and to the first group of ground engaging members, the electric motor providing power to at least one of the first group of ground engaging members;a rear drive system supported by the frame and positioned adjacent the frame rear end, the rear drive system being operatively coupled to the electric motor and to the second group of ground engaging members, the electric motor providing power to at least one of the second group of ground engaging members;a plurality of batteries supported by the frame;an electronic controller which controls a provision of power from the plurality of batteries to the electric motor including a drive current; anda drive mode input operatively coupled to the electronic controller, the electronic controller operating the electric vehicle in one of a plurality of drive modes based on the drive mode input, wherein in a first drive mode the electronic controller limits the drive current in a first non-linear fashion based on an rpm of the electric motor and in a second drive mode in a second non-linear fashion based on the rpm of the electric motor. 9. The electric vehicle of claim 8, further comprising a prop shaft coupling the electric motor to the front drive system, the prop shaft extending through a longitudinal opening in the plurality of batteries. 10. The electric vehicle of claim 8, wherein at least one of the first non-linear fashion and the second non-linear fashion includes a plurality of linear segments.
