SR1 to SR6
Ocelote and Coati use SR1; Jaguarundi and Morfo use SR2; Quetzal and Fragata use SR4; Salvador and Unión step to SR6.

AVENTURO ENGINEERING
Vehicle pages tell you what an Aventuro has. Engineering explains what each technology means and how it works through explanations, diagrams and video.
SR · DEEP DIVE
THE MECHANICAL HEART
SR is Aventuro’s star-rotary architecture: a family of engines built around the housing, star rotor and Mantis mechanism, then scaled for different vehicle families.
Heart vs power unit
The SR heart is the housing, star and Mantis arm. Plugs and hoses complete the SR engine, while the outer cover, transmission relationship and surrounding auxiliary hardware belong to the larger power-unit installation.
Designed alongside the chassis
SR1/R1M and the chassis are intended to be manufactured together in El Salvador before shipment, keeping engine packaging and vehicle structure part of the same engineering problem.
MECHANICAL CORE
One SR architecture, scaled by family.
SR + Mantis
The concept combines a star-shaped rotor, hexagonal housing, movable chamber geometry and the Mantis mechanism. The architecture scales from SR1 through SR6 while retaining the same core idea.
Ocelote + Coati · SR1
The compact SR tier serves both families: high-revving sports character for Ocelote and a softer luxury-focused interpretation for Coati.
Jaguarundi + Morfo · SR2
SR2 supports Jaguarundi's performance-luxury character and Morfo's transformation-focused engineering.
Quetzal + Fragata · SR4
SR4 supports Quetzal's grand-touring role and Fragata's stronger high-performance GT focus. Salvador and Unión step to SR6.
STAR-ROTARY ARCHITECTURE
A mechanical family, not one engine.
SR heart
Housing, star rotor and Mantis arm form the mechanical heart. Plugs and required fluid connections complete the SR unit; surrounding accessory hardware belongs to the larger engine assembly.
Scaled family
SR1, SR2, SR4 and SR6 scale the concept for different Aventuro families, while multi-rotor assemblies extend the architecture around a shared output strategy.
Mantis mechanism
The Mantis arm manages confined chamber motion around the star, combining rotary movement with piston-like chamber control rather than copying a conventional piston engine.
Manufacturing path
The SR1/R1M concept is intended to be manufactured alongside the chassis in El Salvador so powertrain and vehicle architecture develop as one system.
Backward-compatible evolution
Early boxer-powered Aventuros are not meant to become engineering dead ends; factory-engineered SR conversion paths are part of the long-term compatibility concept where practical.
