Modern Family Cars Outperform 1990s Performance Models Despite Smaller Engines

OPA WIRE, Oct 25 (OPA) — New data from Vehicle Data Global (VDG) shows a 28.9 percent increase in engine power output over the past two decades. While average engine capacity has decreased by 7.8 percent since 2005—falling from 1,771cc to 1,633cc—average power per litre has surged by 42.9 percent. This shift reflects a broader industry trend where manufacturers prioritize efficiency without sacrificing performance.

Specific models illustrate this engineering evolution. The current Skoda Octavia 1.5 TSI e-TEC mild hybrid produces horsepower comparable to the 1990s-era Vauxhall Astra GSi and Renault Clio Williams. Similarly, the Nissan Qashqai 1.3 DIG-T mild hybrid generates approximately 156 bhp, surpassing the 2.5-litre six-cylinder engine found in the classic 1970s Triumph TR6 PI. The Ford Puma 1.0 EcoBoost mild hybrid delivers 153 bhp, roughly 16 percent more than the 1980s Ford Escort RS Turbo.

This performance gain is largely attributed to the widespread adoption of turbocharging and electric motor assistance. In 2005, only 8,500 vehicles with engines of 1.5 litres or smaller produced at least 134 bhp. By 2025, that figure reached 444,000 registrations, accounting for 26.7 percent of the market. Ben Hermer, operations director at VDG, noted that the integration of hybrid technology has allowed automakers to maintain high power outputs while adhering to increasingly stringent environmental legislation.

Engine downsizing appears to be plateauing as manufacturers shift focus toward further optimizing existing powertrain architectures. While average engine capacity remained relatively stable between 2019 and 2025, power outputs continued to climb from 105kW to 111kW. This indicates that the industry is moving toward a phase of refinement where efficiency gains are achieved through advanced combustion management and electrification rather than further reduction in displacement.
