SRT has introduced a new performance concept called eBoost Air, an electric-compressor system designed to eliminate turbo lag in the 3.0-liter Hurricane inline-six engine.
The setup places an electrically powered compressor upstream of the conventional turbos, using an electronically controlled bypass to route air through it when the driver demands torque before the turbos spool up.

The system is showcased in a concept Jeep Grand Cherokee SRT, but SRT has not confirmed any production plans or specific vehicle applications.
How eBoost Air Works
SRT developed eBoost Air around a prototype version of the Hurricane High Output engine.
The electric compressor can produce usable boost from idle, filling the dead space before the exhaust-driven turbos reach full speed.
As revs rise and exhaust energy becomes sufficient, airflow returns to the normal induction path.
SRT claims this provides a broader and more linear powerband, resembling the feel of a supercharged V8 while maintaining high-rpm performance.
The system is not production-ready, and no horsepower, torque, voltage, or test data have been released.

The current Charger Scat Pack's Hurricane-based SIXPACK H.O. makes 550 hp (410 kW) and 531 lb-ft (720 Nm), with peak boost at 30 psi.
An e-compressor could make the six-cylinder's response feel more muscular without downsizing the turbos.
Other brands like Mercedes, Audi, and Volvo already use similar technology, so the concept is feasible.
However, eBoost Air will require energy, cooling, and under-hood space, adding cost and complexity.
Stellantis executive Tim Kuniskis says there's "no downside" to the system, but Dodge will need to address heat management and other challenges.
