BOGOTÁ, Colombia -- September 19, 2013

The Sistemas Sustentables and ISSRC have released third-party test results
from Bogota Columbia announcing the BYD electric bus Andino-12 (the 40 foot
BYD all-electric bus) had successfully concluded two weeks of intensive
testing and evaluation. The general purpose of the program was to carry out
operational testing to determine electric-bus feasibility in Bogota’s
Integrated Public Transport System. The BYD Andino-12 electric bus had a
carrying capacity of 80 passengers with a specified range of over 250 km.

The testing was carried out in Bogota on a route specified by Transmilenio
S.A. Shown in the figure below, the test route covered around 700 km with a
total testing time of 40 hours under various traffic conditions, road surfaces
and gradients. The tests were carried out under two different load conditions
(full load and 70% loaded), according to the various protocols and manuals.

The Andino 12’s average performance on route was 1.13 km/kWh (exceeding even
BYD’s specifications of 1  km/kWh). In terms of passenger perceived noise, the
average values obtained were considerably below the Colombian standards, 61.44
dB and 66.87dB with the windows closed and open (the maximum standard in
Columbia is 80 dBA). When the bus is stopped, it does not generate any noise
since the motor parts are static (i.e. it does not have an idling mode like a
traditional internal combustion engine). The results obtained fell well within
required values set in the Colombian standard (daily limit of 50 μg/ m36),
regardless of whether the vehicle circulates with the windows closed or open
(20.2 and 31.8 μg/m3 respectively). The bus did not present any problems in
terms of range and regeneration and was completely reliable. The single-charge
range of the Andino 12 was confirmed between 270 and 280 km, which complies
with Bogota requirements for operating within the system.

Last October, BYD’s electric bus participated in the C40 Hybrid & Electric Bus
Test Program in Colombia. This event is endorsed by The Clinton Climate
Initiative (CCI) and InterAmerican Development Bank (IABD). For more detailed
