Allison Transmission, Alexander Dennis collaborate on electric version of top selling double decker bus

At the Advanced Clean Technology Expo, two industry leaders announced a collaboration aimed at bolstering the electrification of transit buses. Allison Transmission, a global leader in commercial-duty propulsion solutions, and Alexander Dennis, one of the world’s leading bus and coach builders, are working together to develop efficient, powerful electric buses.

A first step in this strategic alliance is Allison’s new ABE Series electric powertrain systems for low-floor bus applications, which will premiere with the Foothill Transit launch order for Alexander Dennis’ interurban and commuter Enviro500 3-axle double decker buses in North America.

The buses, which have the same footprint as a conventional single-decker bus, can carry up to 86 seated passengers, and provide superior handling and a quiet and smooth zero-emission ride.

The range includes a line of fully-integrated electric axles designed to fit a variety of transit configurations, including low and ultra-low floor, articulated, double-decker and conventional chassis.

It offers a bolt-in solution, available in single- and multi-speed options, requiring no modifications to existing bus frame or suspension

It features integrated electric motors, power electronics, multi-speed gearing, proprietary oil cooling and pump, providing continuous power and ability to run closer to peak power for longer durations.

It offers an efficient and powerful solution for bus fleets today, capable of operating without restrictions at motorway speeds and on all required grades

Allison Transmission is the world’s largest manufacturer of fully automatic transmissions for medium- and heavy-duty commercial vehicles.

“Allison has a long history with the bus and transit market utilising our electric hybrid system. This is the next evolution of electrification in this market, and we are pleased to meet the needs and expectations of our customers,” said David S. Graziosi, Allison Transmission, President and CEO.

He added: “We are delighted to collaborate with Allison on our first electric double decker order in North America for Foothill Transit,” said Robert Davey, President, Alexander Dennis. “As the world’s largest double decker bus manufacturer, we see an increasing demand for electric buses, which combines the same high-passenger capacity and outstanding comfort that our vehicles are renowned for, with zero-emission technology. Partnering with Allison, and leveraging their technology expertise, is helping us achieve this goal.”
