subject: Prototype Solar Power-Assist for Buses [print this page] The buses have another mechanism working for them i.e. ZF Astronic transmission. It is a 12-speed manual transmission but its beauty is it behaves like an automatic version. ZF Astronic transmission takes into account the load, speed and road conditions. Then it analyzes these parameters dell latitude d520 battery and the transmission decides which is appropriate "shifting". Fuel economy tests demonstrate a more than 6% increase in performance.
