Mercedes-Benz to Offer Petrol Engines Alongside EV Option for ‘Baby’ G-Class

12

Mercedes-Benz is set to buck the trend of all-electric launches by offering petrol engine options alongside electric drivetrains for its upcoming compact G-Class model, often dubbed the “Baby G-Wagen.” This decision comes as automakers reassess the pace of EV adoption and consumer demand.

Hybrid and Combustion Options Confirmed

According to reports from Autocar, the new model will provide buyers with a choice between hybrid and pure-electric configurations. The hybrid system is expected to mirror the setup found in the latest third-generation CLA, utilizing a 1.5-liter turbocharged four-cylinder petrol engine paired with a 48V mild-hybrid system. This engine comes in three power outputs: 100kW/200Nm, 120kW/250Nm, and 140kW/300Nm.

The hybrid setup combines this engine with an eight-speed automatic transmission and a 20kW electric motor powered by a 1.3kWh battery. This provides a bridge for consumers not yet ready for full electrification.

Why the Shift? EV Adoption Rates and Market Realities

The inclusion of petrol options reflects a wider industry trend where legacy automakers are hedging their bets on EV-only futures. While EV sales are growing, adoption rates haven’t met early projections, varying significantly by region. Europe and China have seen stronger uptake, but other markets lag behind.

Mercedes-Benz’s experience with the full-size G-Class likely informed this decision. Despite offering a powerful electric G580 variant, sales have been underwhelming, with internal sources reportedly calling it a “complete flop.” This suggests that a wider range of powertrain options is essential to maintain strong sales volume.

Baby G vs. Full-Size G: Technical Differences

The “Baby G” will be significantly smaller than the standard G-Class, measuring approximately 4.4 meters in length compared to the full-size model’s 4.86 meters. The electric version is expected to utilize a two-motor setup—unlike the full-size G-Class’s motor-per-wheel system—with a larger, more powerful motor on the rear axle.

Mercedes-Benz has internally referred to the new model as the “Baby G,” “Mini G,” or “Little G,” but the final name remains unconfirmed. Production is scheduled to begin in 2027, with electric variants launching first, followed by petrol-powered models at an unspecified later date.

The inclusion of petrol options in the Baby G-Class underscores the pragmatic approach automakers are taking to electrification, acknowledging that a diverse powertrain lineup is crucial to meeting varying consumer preferences and market conditions.
