Jonathan Storey's financial analysis covers four decades of performance data on the world's largest automakers and their subsidiaries, spanning from 1983 through 2025. The dataset tracks revenue, profitability, asset turnover, and return on equity across the industry's major players.
This historical perspective reveals how the automotive sector has transformed over nearly half a century. The 1980s marked the rise of Japanese manufacturers challenging Detroit's dominance. The 1990s and 2000s saw consolidation, with Volkswagen Group, Toyota, General Motors, and Renault-Nissan emerging as true global powers. Recent years show how electric vehicle investment, supply chain disruption, and margin compression have reshaped profitability metrics.
Key ratios illuminate competitive strengths. Return on invested capital separates efficient operators like Toyota from capital-intensive ventures struggling with EV transition costs. Operating margins reveal which groups command pricing power and which face relentless cost pressure. Asset turnover metrics show whether manufacturers squeeze maximum revenue from their factories and dealer networks.
The data exposes real winners and losers. Tesla's valuation contradicts its actual profitability when measured against traditional automotive metrics. Legacy manufacturers in Europe face structural challenges as they retool for battery production. Chinese automakers like BYD now rank among the world's largest by volume, forcing a recalibration of industry rankings.
This analysis serves multiple audiences. Investors use these ratios to assess which automakers will survive the EV transition intact. Suppliers track their customers' financial health to manage credit risk. Employees and unions monitor profitability to inform wage negotiations. Regulators examine consolidation patterns and pricing power.
The 42-year span matters because it captures cyclical downturns, technological disruption, and structural change. The 2008 financial crisis nearly destroyed Detroit. The 2015 emissions scandal
