Electric Bus Sets Record With 1,101-Mile Trip on a Single Charge

Think it was impressive when a Tesla club drove a Model S nearly 670 miles? It has nothing on what Proterra just managed. The startup just drove a Catalyst E2 Max electric bus a whopping 1,101.2 miles on a single charge. That's the furthest any EV has managed before recharging, and well past the 1,013.8 miles driven by the previous record-holder, a one-seat experimental car nicknamed "Boozer." It's not hard to see how Proterra managed the feat when you know about the technology, but this still bodes well for eco-friendly public transportation.

    A heavier bus beats the hell out of the streets, a wheel with a built in electric motor (should they go that way) not only beats the pot holes but also beats the motors.

    I'm not sure how just moving the motor to the wheel helps beat potholes: wouldn't it increase the unsprung mass [wikipedia.org] and make things worse?

    It doesn't help beat potholes, it makes it far worse for exactly the reason you state. In-wheel motors are a terrible idea mostly because of unsprung mass; that's why no one uses them. frojack bringing them up is just a red herring; it's like complaining about how bad Linux is because you don't like twm [wikipedia.org].

    In-wheel motors might make sense in the future if they ever figure out how to make motors out of some kind of ultra-lightweight material, rather than iron and tons of copper. For now, they're just dumb, though I guess they might make sense on a vehicle that has no suspension at all.

      This part of the whole discussion seems a little pointless, however. These buses don't have in-wheel motors, it has a 2-speed AWD drivetrain.
