Stellantis to Equip 2028 Jeep Compass With 48V Bio-MHEV Technology

Stellantis Plans 48V Bio-MHEV Jeep Compass

Stellantis will equip the 2028 model Jeep Compass C-segment SUV with Jeep Compass 48V bio-MHEV technology developed in Brazil, according to multiple media reports dated August 26. The move forms part of the company's broader electrification strategy for the South American market and follows the start of mass production of the Jeep Avenger with 12V bio-MHEV technology in July 2026. The Avenger is being produced at the Porto Real plant in Rio de Janeiro, demonstrating the company's use of locally developed electrification solutions alongside existing combustion technologies. The planned Compass application will extend this approach to a larger vehicle and a higher-voltage mild-hybrid system.

Powertrain and Production Details

The South American Jeep Compass will combine a 1.3L turbo flex-fuel engine with an e-DCT and 48V bio-MHEV technology. Production of the vehicle takes place at the Goiana plant in Pernambuco, where the same manufacturing operation is also associated with the reported 2027 Renegade application of this MHEV technology. The combination is designed around the regional market's existing flex-fuel powertrain environment while adding a 48V mild-hybrid system. The development reflects the growing role of electrified powertrains that can work with locally relevant fuels and manufacturing capabilities rather than relying exclusively on fully electric vehicle architectures.

Small Wide 4x4 Platform Remains

The 2028 South American Compass will continue using the Small Wide 4x4 shared platform at the Goiana plant. This differs from the STLA Medium platform used by the third-generation Jeep Compass launched in Europe in 2025. The platform distinction is significant because the South American vehicle follows a separate technical and production path tailored to regional requirements. The continued use of the Small Wide 4x4 architecture also indicates that the planned 48V bio-MHEV configuration will be integrated into an established platform rather than requiring the local vehicle to transition immediately to the newer architecture used for the European-market Compass.

Brazilian Electrification Strategy Expands

The planned Compass application builds on Stellantis' broader electrification strategy in Brazil and the wider South American market. The July 2026 start of mass production for the 12V bio-MHEV Jeep Avenger provides an earlier example of the company's regional approach, while the proposed 48V system represents a further development of mild-hybrid technology. These programs show how electrification efforts can combine combustion engines, alternative fuels and hybrid assistance within existing regional production operations. The approach also allows Stellantis to expand electrified vehicle offerings while maintaining compatibility with market-specific powertrain requirements and manufacturing infrastructure.

Potential Leapmotor Technology Integration

Expansion work is also underway at the Goiana plant to prepare for local assembly of the Leapmotor C10 and B10. According to local reports, there is a possibility that Leapmotor's range-extended electric vehicle, or REEV, technology could eventually be incorporated into the 2028 Compass. If implemented, such an integration would introduce another electrification pathway alongside the planned 48V bio-MHEV system. The potential connection with Leapmotor is therefore notable because the plant could support multiple electrification approaches, including mild-hybrid and range-extended electric technologies, as Stellantis develops its South American vehicle portfolio.

Frequently Asked Questions

What technology will Stellantis use in the 2028 South American Jeep Compass?
The 2028 South American Jeep Compass is planned to use a 48V bio-MHEV system developed in Brazil, paired with a 1.3L turbo flex-fuel engine and an e-DCT transmission. The vehicle is expected to continue using the Small Wide 4x4 shared platform at the Goiana plant in Pernambuco rather than the STLA Medium platform used for the third-generation Compass launched in Europe in 2025. Local reports also indicate a possibility that Leapmotor's range-extended electric vehicle technology could eventually be incorporated into the vehicle, although that integration remains a reported possibility rather than a confirmed production specification.
