Cover Story: Electric vehicles make tonal drivetrain orders and high-frequency artifacts more audible, yet most NVH diagnostics still assume a tachometer and specialized sensors. We present a tacholess, physics-informed smartphone pipeline and open benchmark that synthesizes realistic order content, impacts with ring-down, and mixed noise, and then recenters harmonics via ridge-guided order tracking to separate tonal and residual components. Interpretable, order-invariant ratios and residual descriptors feed lightweight models and calibrated severity heads, enabling reproducible evaluation across SNR, RPM profiles, and domain shift.
