When the Jeep Avenger first broke cover, it arrived as a bold symbol of a silent revolution—the first-ever all-electric Jeep. But as we move into 2026, Jeep is proving that they haven’t forgotten the “traditionalist” adventurer. In a strategic move to broaden its appeal across diverse markets, Jeep has officially launched a new Turbo 100 petrol engine, bringing a visceral, mechanical soul back to its smallest SUV.
The message is clear: whether you want to plug in or fill up, the Avenger is ready for the journey. This new addition isn’t just a placeholder; it’s a highly engineered response to the “freedom of choice” that modern commuters and weekend warriors are demanding.
1. Under the Hood: The New “Turbo 100” Unit
The heart of this new variant is a 1.2-liter turbocharged three-cylinder engine. But don’t let the cylinder count fool you—this is a modern, high-efficiency unit designed for the grit of city traffic and the openness of the highway.
- Output: The engine delivers a punchy 101 HP (74 kW) and 205 Nm of torque.
- The Transmission: In a win for driving enthusiasts, this engine is paired exclusively with a 6-speed manual gearbox. In an age of increasingly automated driving, the inclusion of a “three-pedal” setup offers a tactile connection to the road that many purists still crave.
- Variable Geometry Turbo (VGT): This new engine features a VGT system that optimizes response at low RPMs, making overtaking effortless and urban “stop-and-go” much smoother than traditional small-displacement engines.
2. Engineered for Durability: The End of the Wet Belt?
One of the most significant upgrades in this new petrol iteration is under the skin. Jeep has moved away from the “wet belt” (belt-in-oil) design found in previous Stellantis-sourced engines, opting instead for a timing chain.
This is a major win for long-term owners. A timing chain significantly enhances engine durability and simplifies the maintenance schedule. In fact, Jeep has optimized the service intervals for the Turbo 100 to just once every two years or 15,500 miles, providing a lower cost of ownership for those who plan to keep their Avenger for the long haul.
3. Ruggedly Refined: Design and Capability
Despite the change in powertrain, the Avenger remains an authentic Jeep. It doesn’t lose an ounce of its rugged personality just because it’s burning petrol instead of lithium.
- Authentic Ground Clearance: The petrol model retains its best-in-class 200 mm of ground clearance.
- Off-Road Angles: With an approach angle of 20° and a departure angle of 32°, this is a “city car” that isn’t afraid of a rutted trail.
- Selec-Terrain as Standard: Even on the petrol manual, Jeep includes its signature Selec-Terrain system (Normal, Eco, Sport, Snow, Mud, and Sand) and Hill Descent Control, ensuring that “Concentrated Freedom” is more than just a marketing slogan.
4. The 2026 Facelift: A Modern Glow-Up
The arrival of the new gas engine coincides with the 2026 Avenger Facelift. The most striking change is the revised seven-slot grille, which now features integrated LED lighting signatures. It’s a high-tech look that mirrors the larger, upcoming Jeep Compass and Wagoneer S.
Inside, the cabin has seen a boost in material quality. Soft-touch door cards and a new rubberized drive mode selector provide a more premium, tactile feel. The 10.25-inch Uconnect system remains the centerpiece, offering wireless Apple CarPlay and Android Auto to keep you connected even when you’re off the grid.
5. The Verdict: Who is the Petrol Avenger For?
The Jeep Avenger Petrol is for the pragmatist. It’s for the driver who isn’t quite ready for the EV lifestyle—whether due to charging infrastructure or the desire for a lighter, more nimble vehicle.
With a starting price significantly lower than its electric sibling (ranging from approximately £22,000 to £26,000 depending on the trim), it opens the door to the Jeep brand for a whole new generation of buyers. It’s a small SUV that proves you don’t need a massive V8 to feel the spirit of adventure; sometimes, a clever turbo and a manual stick are all the freedom you need.
