Calif.’s Antelope Valley Transit Authority’s (AVTA) new electric BYD bus is performing better than advertised, according to the company.

AVTA and BYD operators put the electric bus to the test this weekend during a 24-hour marathon ride that looped from Rosamond to Palmdale a total of 18 times.

The BYD bus managed to travel an astounding 746 miles over the 24-hour period, operating in three shifts. Each shift logged between 240 and 256 miles before recharging the battery.

“This is tremendous news and it proves the BYD electric bus can be a transit work horse like its diesel counterpart,” stated Board Chair Norm Hickling. “We are looking forward to putting our electric buses into service on local transit routes to further evaluate their true performance under all weather and road conditions.”

AVTA’s electric bus was loaded with 5,250 lbs. of sand bags to simulate the weight of 35 passengers. The bus traveled a total of 240 miles before its first battery charge, which is nearly 100 miles more than BYD advertises and 30 miles more than is needed to service an average transit route in the Antelope Valley.

The air conditioning system ran during most of the test except during the early morning hours when it was cold outside.

This is the second test for AVTA’s electric bus. Its first unofficial test was July 29 when it traveled to Los Angeles to pick up the consul general of the Chinese Consulate who was scheduled to tour the BYD manufacturing facility in Lancaster.
