Months of rigorous testing deliver record-breaking results

There’s always a lot of talk in the transit industry about how to make public transportation more efficient, effective, and just an overall better experience for riders. But every now and then, something happens that truly makes the industry stand up and take notice. Most recently, that was BAE Systems’ Gen3 electric drive system, which made trade headlines after acing testing at the Federal Transit Administration’s (FTA’s) test track in Altoona, Pennsylvania.

So why is this a big deal? This new drive system is the next generation of hybrid-electric technology that is built to make buses quieter, cleaner, and easier to maintain. In real-world testing, it delivered record-breaking fuel economy for a North American hybrid bus: 6.6 miles per gallon. That’s not just impressive—it sets a new industry benchmark.

But performance wasn’t the only thing that stood out. Gen3 was designed to be simpler and more modular, meaning fewer components, connections and cabling…  just easier upkeep overall. For transit agencies constantly dealing with budget pressures and maintenance headaches, that kind of efficiency is a huge bonus.

It also means a smoother ride for passengers, lower emissions for cities, and more uptime for fleets. And there are financial incentives available: transit agencies can access FTA grant funding to help bring Gen3 into their operations, making it an even smarter investment.

BAE Systems has nearly 30 years of experience in electric propulsion, and their systems are already powering 19,000 buses around the world. That kind of track record makes a difference when it comes to trust and reliability.

Why This Matters

  1. It’s a smart step toward zero emissions.  Not every city is ready for full battery-electric fleets. Gen 3 is a powerful middle ground that cuts emissions now while building a bridge to the future.
  2. It’s built for the real world. Designed for daily service, Gen3 holds up under pressure and simplifies life for maintenance teams.
  3. It’s backed by data. The Altoona tests didn’t just look good on paper. The system proved itself over months of testing that covered fuel economy, emissions, maintainability, and noise levels.
  4. It helps agencies move faster. With federal funding available and the trusted BAE Systems name behind it, Gen3 is a lower-risk, high impact way to upgrade fleets.


So, the bottom line is this: BAE Systems just delivered a major win for transit systems anywhere that want to go greener without skipping a beat. The Gen3 electric drive system is a powerful example of innovation that works in the real world, and it’s exciting to think about the difference it can make as more cities and agencies get on board.
