The energy efficiency of electric buses from BYD didn't get lost in translation, apparently.

The Chinese company entered its all-electric buses in a fuel-efficiency testing program put on in Colombia by the Clinton Climate Initiative (CCI) and InterAmerican Development Bank (IABD), and the buses came up big.

Running against diesel and CNG-hybrid buses on a 12-mile route through Bogota that took between 60 and 90 minutes to complete, BYD's bus achieved a 7.3 km/liter-equivalent by measuring costs and 11 km/liter-equivalent measuring by energy output, which was the best among the buses tested. By our math, that comes out to between 17 to 26 miles per gallon equivalent, which doesn't sound great relative to cars, but is three to four times what the typical smoke-belching diesel bus gets.

BYD says the 200-plus electric buses it has put into service in Shenzhen, China have put on more than 5.5 million miles. In June, the company sold six buses to the Dutch island of Schiermonnikoog. In May, BYD won a contract to sell the city of Windsor, Ontario, for what was said to be the first North American municipal fleet of all-electric buses. BYD's press release is available below.

BYD electric buses take top spot in real-world fuel efficiency test
  • Bus Technology Comparisons Released by Clinton
  • Climate Initiative C40 Cities Program
  • BYD electric bus reported to have best fuel efficiency in kilometers per liter
BOGOTA, Colombia, Oct 06, 2012 -- The Clinton Climate Initiative (CCI) and InterAmerican Development Bank (IABD) have released results from Bogota, Colombia third party testing in a side-by-side comparison of diesel, CNG/hybrid and BYD all-electric buses.

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 Bogota.

Buses were tested side-by-side on a Bogota 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 Bogota. 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.

      Plus, they emit very little noise pollution, which is a major gripe of diesel buses, especially if you live and walk around major cities everyday.

      A nice step, but it's not "zero emission" unless Colombia's power plants are zero emission.

        The Article never said they were zero emission. That is why they were promoting the MPGe. Regardless of what the power situation is like in Columbia - these will still be lower emissions than the diesel busses that they are replacing. That being said - Columbia has a pretty green power grid with 64% coming from Large Hydro-Electric Plants, 3% Coming from Small Hydro-Plants, 27% Natural Gas (cleaner than coal), 5% Coal, with the remainder coming from other sources (Less than 1% Wind and Solar).

        70% of Colombia's power comes from hydroelectric power. https://en.wikipedia.org/wiki/Hydroelectric_power_in_Colombia They also have many very favorable sites where wind farms could be installed.

      "The Article never said they were zero emission." I'm referring to the picture.

      Regardless of power source, the fact that the vehicle *itself* does not emit anything is still important, as anyone who has been a pedestrian or cyclist in a city can attest.

      I am an environmentalist, and I understand about the salmon and how important they are to the ecosystem in the northwest... but having access to clean electricity that doesn't pollute the air and water is just way too important to give up. Beyond being non-polluting and essentially free hydro is also great because it can spin up and down so quickly that it is a great balancing power source for wind power generation which can be erratic.

      I wish I had contact info to obtain this bus in America

        There are EV buses enroute to America, don't worry.

      Hey, that's great. Here in Washington State we get a lot of hydro power too. We officially don't allow hydro to legally be considered as a renewable source of power, for politically manipulative reasons.

      I make that about 2.4kwh/mile, perhaps not bad for such a large, heavy vehicle

        I'm always suspicious of MPGe, since some institutions use official conversion factors that have little basis in reality. That number, however, seems pretty plausible. The BYD site claims 1.66 kWh/mile http://www.byd.com/auto/ElectricBus.html#p2 which is likely optimistic, since they are not held to any regulatory or reporting accountability. Either of those numbers is not bad, given that an 'empty' bus is still likely to have a half dozen people on it, while a full bus could have more people than the 27 seats would hold, bring per-seat consumption to very reasonable levels.
