A study by the German motoring group ADAC has revealed marked differences in the lifespan of batteries in cars with hybrid powertrains.

According to the findings, Mercedes-Benz hybrids deliver the strongest battery retention, sustaining high performance levels up to 200,000 km. This points to well-chosen components and a power management system that does its job without fuss, the kind of consistency that reassures long-distance drivers.

At the opposite end sit Mitsubishi models: even short trips noticeably drain capacity, sharply cutting the usable life of their packs. In everyday use, that makes brief, stop‑start journeys particularly unforgiving for these batteries.

BMW’s hybrids show uneven results, with battery performance closely tied to how much the electric side of the drivetrain is asked to work. The harder the e-motor is used, the faster the energy store loses effectiveness—an outcome that underscores how much driving style shapes real-world durability.

As for Ford, the study confirms a steep drop in capacity early in the ownership period. ADAC attributes this to design specifics and the quality of materials—factors that make themselves felt sooner rather than later.
