The energy transition adds hundreds of kilos to vehicles, forcing the auto parts industry to create reinforced products and increasing repair costs in workshops
The adoption of electrified platforms in Brazil started a silent race in the engineering departments of large automakers. With the massive arrival of hybrid and electric vehicles, manufacturers needed to change the geometry and materials of chassis systems to deal with an inevitable technical adversary: gravity. The weight of the battery packs adds up to 30% more load on the axles compared to combustion models, transforming the wear of springs and hydraulic cylinders into one of the main concerns of the automotive industry in the country.
The readjustment of projects in the face of the shock of the weight of the batteries
The architecture of a combustion vehicle was not designed to accommodate lithium-ion modules that weigh, on average, 300 to 600 kilograms. To accommodate this additional mass without compromising directional stability, factories needed to adopt systems with higher compression load and ultra-high-strength steel alloys.
Automotive engineering now uses higher density hydraulic fluids to prevent premature collapse of the assembly on bumpy roads. This change in the original designs also meets the requirements of tropicalization, where automakers adjust the free height from the ground to protect the floor, a critical area where the energy cells are stored.
The bottleneck in the auto parts industry and the adaptation of dealerships
This structural transformation had a strong impact on the entire national supply chain. Traditional manufacturers are racing against the clock to approve new product lines specific to the electrified segment. On the shelves of dealerships and independent workshop networks, the absence of equivalent components in the aftermarket creates waiting lines for imported parts.
Additionally, mechanics need new training. THE high instantaneous torque of electric motors accelerates fatigue of tray bushings and stops, requiring more advanced telemetry equipment and accurate diagnosis during 3D alignment and balancing services.
The financial impact on workshops and risks on the track
At the end of the automotive sector, the vehicle owner feels the direct impact of these technological changes at the time of inspection. Reinforced chassis components for electrified models can cost twice as much as a traditional set, which raises the price of preventive maintenance. Faced with higher budgets and a lack of familiarity with the dynamic behavior of new cars, many drivers postpone repairs and ignore mechanical warnings.
How do you know if your car’s shock absorbers are bad and what’s the danger of driving without changing them?
The most obvious symptoms include excessive body roll during braking, rapid loss of traction when cornering and uneven tire tread wear. The risk of traveling with broken parts is severe: the stopping distance increases significantlythe tire loses contact with the asphalt and the electronic stability systems fail, critically increasing the chance of accidents and rollovers during emergency maneuvers.
The Brazilian mobility scenario for the next five years points to a consolidation of national production of structural components, as hybrid flex platforms gain scale on assembly lines. With the likely nationalization of battery manufacturing and the maturation of local supplier networks, the tendency is for spare parts costs fall gradually. Until then, the production sector will need to balance the innovation of electrification with the harsh reality of the national asphalt, ensuring that the modernization of the fleet does not become a financial barrier to safe driving on the country’s highways.
