American company Proterra has revealed its latest all-electric bus, which it calls ‘the highest-performing bus on the road’

The Proterra E2 electric bus has been revealed, with a 660kWh battery pack that gives it a claimed range of up to 350 miles.

Proterra’s latest bus, which follows in the footsteps of its lighter-duty electric buses, is dubbed ‘the highest-performing bus on the road’ by the American manufacturer, which has built and sold more than 300 vehicles across North America.

The bold tagline alludes to the bus’s range, which Proterra claims is around 350 miles, although under testing the bus did achieve a range of more than 600 miles.

The bus’s biggest available battery pack, at 660kWh, is more than six times that of the flagship Tesla Model S P100D, although the bus takes a leisurely 6.8sec to reach 20mph, as opposed to the Tesla’s 2.5sec 0-60mph time.

Our Verdict

Tesla Model S 95D

In theory, this all-electric luxury car looks a hit. So is it in practice?

This is most likely due to the bus’s kerb weight of just under 15 tonnes, which is kept to a minimum through the bus’s construction – it has a carbonfibre reinforced composite body. A top speed of 65mph is quoted by Proterra.

Charging time for the bus in its highest 660kWh E2 max specification is five hours from a 120kW charge point, while overhead, on-the-go charging is an optional extra.

At almost 13 metres long, the Proterra E2 max has seating for 40, and at full capacity will weigh almost 18 tonnes.

There's been around 8 electric buses operating in Milton Keynes since 2014, they're even charged wirelessly. Could Autocar provide an update of something that's been in place for some time (if indeed it is)

Nobody's saying there aren't electric buses out there, but I've never heard of a 660kWh bus with 120kW charging. This is a world first as far as I know, and it's amazing.

I assume it's very expensive, but in terms of practicality, it'd suit almost any bus operation, unlike current electric buses which are mostly just for local, city or infrequent use.

I think that the comment about the 600 mile test range not being attainable during stop start use needs qualification. Sure, the range will be diminished a little bit during stop start travelling, but the degradation will be nothing like as bad as it would be with a diesel bus (with no energy recovery). As I see it, stop start use is perfect for electric vehicles. It is here where pollution is worst with combustion engines - and the problem batteries have with maintaining prolonged high speeds is lessened. Maybe we should be developing something like this to help clean up out polluted cities?

Yes, it seems to me that zero emission bus and delivery vehicles could make a huge difference to urban air quality. Source renewable energy too and it's a real winner.

"Zero Emissions" ? No it aint zero emissions, it has significantly REDUCED emissions, but they aint zero.

XXXX just went POP.

Brighton had electric busses in 1939.

Little better than a trolley bus, but sure to be immensely more expensive. Nothing more than a costly scam to fleece gullible council transport departments.

I don't need to put my name here, it's on the left
