Abstract

This paper presents a comparative field study of high-speed thermal stress and chassis dynamics across four distinct passenger vehicle architectures: a 2022 MG ZS EV (FWD electric), a 2014 BMW 730Ld (RWD diesel sedan), a 2012 Mercedes-Benz ML350 (AWD diesel SUV), and a 2010 Suzuki Swift VDi (FWD lightweight diesel). Testing was conducted on closed public roads with consistent 150 m and 175 m radius curvatures at speeds up to 240 km/h. A standardized "Max Attack" duty cycle was used, comprising full-throttle cornering, threshold braking from apex speed, and a 500 m cooldown at 80 km/h. Testing occurred at three diurnal phases (06:00, 14:00, 17:00) to capture ambient and asphalt temperature effects.
