Taking the Gillig 4011H home, a 2008 hybrid bus home. Nothing grows older faster than the future.

I remember when they were new buses, something to try out because they were going to be future of a green, energy efficient economy in an era when gasoline cost $4.20 a gallon locally, and climate change was a problem that everybody thought was a critical crisis to be addressed. Back when Barack Obama was a Senator, and even the New Hampshire Primary was in the distant future. Congress had recently passed the Energy Policy Act of 2007, signed into law by President George W. Bush, that would among other things save billions of kilowatts and millions of gallons of gasoline with more efficient automobiles and consumer lighting technology. Different times for sure.

Chevrolet Bolt EV Traction Motor – Deep Dive – YouTube

Stupid automotive question: Why does the Chevy Bolt have a physical shift linkage for PRNDL, that controlled by an actuator, when all that's inside the "transmission" is a parking pawl and a sensor that indicates the position the transmission is located in to tell the computer which way to control the motor? It's not like the physical shift linkage moves any gears. Electric motors don't have gears, they have 100% torque at 1 MPH and reverse by reversing the direction of the electricity.

Government regulation? What GM had in the parts bucket? Unneeded complexity? Doesn't make much sense to me.

The dissassembly of the engine of the Chevy Bolt EV is fascinating. It's very different then a conventional gasoline automobile under the hood.

I am actually surprised how truly different the power train is -- and in many ways simpler then a gasser or diesel -- no emissions equipment, no transmission or gear box. Nearly every component is electrical, there is no serpentine belt or alternator. Interestingly enough, the cabin heat uses anti-freeze like a conventional automobile.

California Requires New City Buses to Be Electric by 2029

California Requires New City Buses to Be Electric by 2029

If the CARB mandate is met with four years - 2023 - one in four new city busses bought in California will be electric powered. By 2029, all new busses will be electric. It's an aggressive mandate, maybe not fully reachable but it will certainly incentivize public transit authorities to invest in the substations, charging equipment and electric maintenance equipment to make an all electric bus fleet possible.
