Downsizing na indústria automotiva brasileira: um estudo de caso sobre a viabilidade técnica e econômica entre os motores 1.0 TSI e 1.6 MSI

Abstract

This study analyzed the technical and economic feasibility of downsizing technology in the Brazilian automotive market through a comparative assessment of the Volkswagen 1.0 TSI and 1.6 MSI engines. The research adopted an applied, qualitative, and quantitative approach, based on a literature review, documentary analysis, technical data sheets, official fuel consumption data, scheduled maintenance costs, market prices, and technical information regarding the systems used in both powertrains. The analysis considered performance, energy efficiency, fuel consumption, maintenance costs, durability, emissions, and total cost of ownership. The results showed that the 1.0 TSI engine offers better performance, mainly due to its higher torque availability at low engine speeds, as well as lower fuel consumption in the models evaluated. Regarding preventive maintenance, the cost differences up to 60,000 km were relatively small, although the TSI engine has a more complex design and components that may increase expenses in the event of corrective maintenance. The economic analysis indicated that the benefit provided by lower fuel consumption depends on the vehicle model, driving conditions, fuel price, and annual mileage. When fuel prices are similar, the 1.0 TSI engine tends to offset its additional costs through fuel savings. However, this advantage may be reduced when more expensive fuels and low annual vehicle use are considered. It is concluded that downsizing technology is technically feasible and provides clear benefits in terms of performance and efficiency, although its economic advantage is not the same for all user profiles. The 1.6 MSI engine remains a suitable option for users who prioritize mechanical simplicity, predictable maintenance costs, and lower design complexity.
