BYD participated in the C40 Hybrid & Electric Bus Test Program in Latin America across several cities in partnership with the CCI C40 and the IADB starting in March 2012. The C40-CCI Program’s Colombia test routes included a wide range of technically feasible driving conditions on representative streets of Bogotá. Buses were tested side-by-side on a Bogotá circuit that had a length of over 19.6 km (12.25 miles) and approximately 1 - 1.5 hours on the route, depending on traffic conditions. BYD Electric Bus was reported to have the best fuel efficiency in kilometers per liter, with an average of 7.30 km/L-eq (costs) or 11.03 km/L-eq (energy output), obtained from 47 repetitions of approximately 30 minutes each, while driving in the real traffic conditions of Bogotá. The same results expressed as fuel consumption are 14.29 and 9.46 L-eq/ 100km, respectively or 0.91 kWh/ km (or 1.45 kWh/ mile) in terms of energy consumption.
Manuel Olivera, Director of the C40-CCI Hybrid & Electric Bus Test Program, stated, “BYD’s participation in our innovative program shows leadership and commitment to reducing greenhouse gas emissions and other local air pollutants in Latin American cities. Through the publication of results in a spirit of collaboration, we are able to demonstrate performance benchmarks for emissions and fuel efficiency across a range of buses, spurring technological and market development in many countries around the world.” The core technology of the BYD electric bus is the self-developed Iron-Phosphate battery technology boasting the highest safety, longest service life and most environmentally-friendly rechargeable chemistry in any electric bus today. The 200+ BYD electric buses, in service in Shenzhen China, have accumulated over 9,216,000 km (or 5,529,600 miles) by the end of August. BYD has seen a rapid increase in the number of deals they are signing in the past two months for its GreenCity (or 12m long K9) electric bus. Sales have been recorded in China, Nederlands, Finland, Uruguay, Israel, Canada and the United States and bus demonstrations have been completed or started in Colombia, Chile, Peru, Germany, Hungary and Spain.
