Evaluating Automobile System Performance and Economic Viability in Nigeria: Evidence from Port Harcourt
Abstract
This study evaluated the system performance and economic viability of automobile vehicles within the Nigerian context, with specific focus on Port Harcourt, Rivers State. The study examined key technical performance indicators such as engine efficiency, fuel consumption, brake responsiveness, suspension quality and electronic control systems, alongside economic factors including purchase price, maintenance expenses, fuel costs and resale value. A descriptive research design was adopted, and data were collected through structured questionnaires administered to automobile owners, commercial operators, mechanics and dealership personnel. Out of 320 questionnaires distributed, 298 valid responses were obtained and analyzed using descriptive statistics, including frequency tables and percentages. The findings revealed that engine power, fuel efficiency and braking systems are critical determinants of vehicle reliability, safety and operational efficiency. Fuel costs, acquisition expenses and maintenance requirements were identified as the major economic factors affecting automobile ownership and sustainability. The study further identified infrastructural deficiencies, fluctuating fuel prices, inadequate spare parts availability and weak regulatory enforcement as significant constraints affecting both system performance and economic viability in Nigeria. The study concluded that improving automobile sustainability requires an integrated approach involving technological innovation, improved maintenance practices, supportive government policies and infrastructural development. Recommendations include the promotion of fuel-efficient vehicles, encouragement of local spare parts production, enhancement of road infrastructure and implementation of stronger automotive regulations.
