The effect of toe adjustment on the Garuda urban gasoline 2020 (UG 20) vehicle glide distance.

Energy efficiency has become one of the most critical pillars of energy-related sectors due to the rapid increases in energy demand and resulting greenhouse gas (GHG). Road transport is the second largest producer of greenhouse gases within the European Union. More efficient vehicles that run on lower carbon-emitting fuels are critical to meeting energy security and climate protection goals. Kontes Mobil Hemat Energi (KMHE) is an event organized by Puspresnas on a national scale. KMHE is a competition against vehicles developed by students to realize low fuel consumption vehicles and energy efficiency. One of the efforts to increase energy efficiency requires a vehicle with a design that can reduce the vehicle's drag resistance and affect fuel consumption efficiency. 2020 Garuda Urban Concept Vehicle design is intended to glide with minimal resistance to achieve the highest fuel consumption efficiency. One friction loss that occurs when the car is running is on the wheels with the road surface. The type of research used is qualitative and descriptive research. The data collected is in words or pictures, so it does not emphasize numbers. When the vehicle slides from the top end of the track, it experiences acceleration caused by the downhill road. The maximum speed achieved by an average vehicle is 20.2 km/hour, with 160 kg vehicle weight. There are differences in time achievement at each recording point, especially when the vehicle is sliding straight on the 0-150 meters track. Because adjusting the wheel to toe 0 will reduce the slip angle on the tire, which causes friction between the tire and the road surface. The distance that the UG-20 can reach with each variable toe adjustment. Different toe adjustments lead to different wheel orientation directions and will cause a force on the vehicle's wheels. The force acting on the vehicle will affect the rolling resistance of the wheels, and the rolling resistance will affect the achievement of the vehicle's sliding distance. The achieved maximum glide distance of the UG-20 when the vehicle has a slight slip angle when crossing the road surface. Based on the results of the toe setting effect of distance on the glide distance of the UG-20 vehicle, it can conclude that the toe distance setting affects the sliding distance with the most optimal glide results—the distance on the toe-out settings of 1mm and 2mm with a distance of 237 meters.
