Performance and speed

Performance and speed guides deal with a golf buggy that still runs but has lost something: slower than it used to be, weak on hills, a sudden drop in top speed, shorter range per charge, speed modes and settings, limp mode, and a vehicle that runs away downhill because regenerative braking is not holding it. Gradual loss and sudden loss have different suspect lists. Gradual decline usually starts with the battery pack: measure it rested, where a full 48 volt lead-acid pack reads close to 50.9 volts, and then watch the meter under load, because a pack that sags hard on a climb and recovers at rest is ageing even when the rested figure looks fair. Low tyre pressures and dragging brakes quietly steal speed and range as well, and a hub that is warm after a drive with little braking is being held back by its own brake. A sudden step change in top speed is more often a setting or a protection state than wear: check whether a speed mode switch has been knocked, and remember that limp mode deliberately caps the vehicle at walking pace when the controller logs a fault. Pressures, pack readings and brake drag checks are owner work. Faults that persist after those checks, repeated limp mode, or any downhill overspeed on a buggy that used to hold itself back involve the controller and its programming, and that is work for a Hawke engineer.
