WE TOOK OURINDUSTRY-LEADING EV BUS AND MADEIT LONGER, LIGHTERAND MORE EFFICIENT.

Proterra® is the first electric bus manufacturer to have completed

Altoona testing, with our electric buses logging more than 500,000

miles in revenue service anywhere in the United States. The new Proterra

Catalyst™ electric bus builds on this record of success, with noticeable

improvements.

The new Proterra Catalyst™ electric bus is 40-feet long, yet still weighs less

than our previous lightweight 35-foot electric bus. It offers the highest fuel

efficiency on the market of 20.8 MPGe, a fast-charge system that keeps

your bus on the road with no overnight charging requirements, one-step

access for ease-of-maintenance and industry-leading ergonomics.

FAST-CHARGE

FLEXIBLE FAST-CHARGINGTHAT FITS EASILY INTOBUS ROUTES AND SCHEDULES.

The Proterra® fast -charge system allows for maximum run time and

minimum wait time. On- route charging can be completed in the time

needed to stop for passengers or a quick driver break. This way, you can

maintain a 24/7 transit system while minimizing extended charging time.

It’s the best of both worlds.

One charging station can accommodate up to 8 buses; even more

when utilized in a larger scale deployment. The charging station is

specifically designed for the average bus route serving downtown

business loops or tourist areas.


How the Proterra charging station works:

Once the Proterra® bus comes within range of the charging station, the station wirelessly connects with the bus

and automatically limits the bus speed to allow for connection. Although the bus is speed limited, the driver

retains full control of the bus at all times during the charging process.

Safe for passengers, safe for drivers.

• All high-voltage areas are clearly identified and designed with redundant automatic and manual service

disconnects

• An automatic insulation test is performed at the beginning of each charge to confirm the safety and integrity

of all high-voltage cables used during the charging process

• During the charging process, the system is constantly monitoring isolation and will cancel the charging process

if an alert occurs

• Multiple separate controllers audit the charging process and each has the capability of cancelling the charge

if anything appears abnormal

• In addition, our composite body, while contributing to overall lighter weight and durability, does not conduct

electricity

LONGER.LIGHTER.SAFER.IMPROVED ERGONOMICS.

The Proterra® EcoRide™ was the world’s first electric bus with fast-charge-

enabled infinite range. The Protera Catalyst™ is a 40-foot electric bus

that continues our proven electric bus tradition, while offering noticeable

enhancements.

The Protera Catalyst™ is built from the ground up to offer our longest

and lightest electric bus, yet is designed to deliver more revenue

per trip. It offers industry-leading, ergonomically advanced design

through a larger cabin, more passenger seating options, the broadest

line of sight on the market and a spacious rear window.

MAINTAINABILITY

SIMPLIFY YOUR MAINTENANCE TO SAVE TIME AND MONEY.

Oil changes are a thing of the past. Without an engine, fuel system,

engine cooling system, exhaust system or emissions after treatments,

maintenance savings with Proterra® can add up to $135,000 over the

lifetime of a bus compared to diesel. And, with a substantial reduction

of parts inventory, you can enjoy more savings.

The Proterra Catalyst™ is also designed with durability and customer

conveniences in mind—such as one-step access to vital mechanical

components—so you can keep your buses moving and lower your total

cost of operation.


MAINTAINABILITY

Compared to diesel:

• Up to $135,000 total savings

• 30% fewer parts

• Reduced maintenance labor

• No engine oil changes

• No liquid fuels

• Regenerative braking = extended time between

brake replacement / repair

• Durable composite bus body is light and

corrosion-resistant

CONTINUOUS 24/7 OPERATION WITH ROUTINE FAST-CHARGING DURING REVENUE SERVICE.

It’s not how far an electric bus can go. It’s how the bus maximizes route

uptime that matters most. The Proterra® Catalyst™ bus was designed

with transit routes in mind. Proterra’s engineering team works with its

customers to design route plans and a strategic, on-route, fast charge

location(s) to allow for continuous operation.

Using its on-route, fast-charging technology, Proterra has demonstrated

that its electric bus can travel over 700 miles in a 24 hour period,

alleviating customer concerns about limited range in Proterra’s electric

buses.

A FOCUS ONSAFETY, FROM TOPTO BOTTOM.

Proterra’s® electric bus utilizes proven, road-tested safety design features.

It is built with a composite body that utilizes the highest strength-to-

weight ratio material available. The composite body utilizes carbon

fiber in key impact and seating areas to further improve strength and

crash resistance.

Battery placement is a critical component of safety. Unlike other electric

buses, Proterra bus batteries are integrated into the vehicle floor,

between the front and rear axles, to keep them isolated from the

passenger compartment and below the vehicle impact line. And all are

reinforced by S2 fiberglass/Kevlar containment structures.

SAFETY


Electric bus technology safety procedures:

• All high-voltage areas are clearly identified and designed with

redundant automatic and manual service disconnects

• An automatic insulation test is performed at the beginning of each

charge to confirm the safety and integrity of all high-voltage cables used

during the charging process

• During the charging process, the system is constantly monitoring isolation

and will immediately cancel the charging process if an alert occurs

Smart, safe battery placement:

• Improves vehicle dynamics due to the low vehicle center of gravity

• Assists in weight distribution for optimal braking and traction

• Keeps batteries isolated from the passenger compartment

• Provides improved protection from collision impact

• Batteries are protected from the elements in water-tight containers

DESIGNED TO LOWER YOUR TOTAL COST OF OWNERSHIP. TODAY AND TOMORROW.

You don’t have to wait the entire life of the Proterra® bus to improve your

bottom line. Transit agencies and municipalities can enjoy a dramatic

reduction in operating costs thanks to higher fuel efficiency, less volatile

energy prices, lower maintenance costs and less wear and tear on local

roads. Control your operating budget, and your maintenance costs, like

never before with Proterra.

FLEXIBLEFAST-CHARGINGTHAT FITS EASILY INTO BUS ROUTES AND SCHEDULES.

The Proterra® fast-charge system allows for maximum run time and

minimum wait time. On-route charging can be completed in the time

needed to stop for passengers or a quick driver break. This way, you can

maintain a 24/7 transit system, and since it allows for distributed grid

loading, it is much easier on the grid. It’s the best of both worlds.

One charging station can accommodate up to 8 buses; even more

when utilized in a larger scale deployment. The charging station is

specifically designed for the average bus route serving downtown

business loops or tourist areas.

ZERO TAILPIPEEMISSIONS COMBINED WITH THE HIGHEST FUEL ECONOMY ON THE MARKET.

The Proterra® Catalyst™ 40-foot electric bus is 100% electric, and

produces zero tailpipe-emissions. Even better, it has no tailpipe

and runs virtually silent. And because it’s lighter—up to 2 tons

lighter than a conventional bus— it causes less wear and tear on

city roads.

Over the lifetime of the Proterra bus, you can save up to $365,000

in fuel when compared to diesel and up to $225,000 when

compared to CNG at current pricing.
