Stellantis’ Street and Racing Technology (SRT) division is developing a prototype powertrain add-on called “eBoost Air,” aimed at reducing turbo lag in forced-induction engines. Multiple reports say the system is designed to provide immediate low-end boost using an electric compressor, rather than waiting for exhaust gases to spool a conventional turbocharger. The concept is described as adding an e-compressor alongside an existing twin-turbo setup, with the goal of bridging the responsiveness gap between low engine speeds and the point where traditional turbochargers deliver sustained boost. One source specifically links the approach to Stellantis’ Hurricane inline-six engine architecture, noting the use of an added e-compressor to complement the twin-turbo Hurricane configuration. Together, the accounts characterize eBoost Air as a working prototype intended to improve throttle response by delivering “instantaneous” boost at lower rpm while conventional exhaust-driven boosting takes over as engine conditions change. Both reports focus on the technology’s purpose and its intended effect rather than production timing or final performance figures.
