GM and Tula Technology, Inc. Team Up to Create Revolutionary Fuel Saving Technology

Back in 2012, General Motors invested in Silicon Valley startup Tula Technology, Inc. with high hopes of developing a revolutionary fuel saving technology. Less than three years later, and GM Ventures is optimistic that its investment will pay off through a technology that could be deployed in future gasoline-powered GM vehicles.

According to a recent news release, “Tula’s Dynamic Skip Fire (DSF) technology uses advanced digital signal processing and sophisticated powertrain controls to create a software-based approach to variable displacement engines.”

That means that instead of relying on fixed cylinder deactivation or switching between fixed patterns like current multi-cylinder engines do, Tula’s DSF technology makes dynamic firing decisions on an individual cylinder basis, delivering the optimal engine torque for all vehicle speeds and loads while avoiding vibration. Testing completed by Tula suggests that DSF technology can improve fuel efficiency in some cars by 15%.

“This technology holds the potential to improve fuel economy on select GM vehicles without degrading power capability when it’s required,” said Jon Lauckner, GM chief technology officer, vice president of Global R&D and president of GM Ventures. “This joint effort combines software expertise from Silicon Valley with powertrain expertise from General Motors.”

Here at Crest Cadillac, we are excited to see what the future holds for this ground-breaking new technology!
