Driver-seat perspective, windows up, inside a 1967 International 304 V8 pickup. Stock engine, 4-speed manual with straight-cut gear whine. Dual 2.25" exhaust, H-pipe, straight-through mufflers. Cabin sound should be deep and muted, with low-frequency V8 rumble, mild mechanical noise, and subdued exhaust resonance. Under acceleration, hear a bassy growl; on shifts, clear RPM drops. On downshifts/engine braking, emphasize vintage transmission whine and soft burble.

High-fidelity automotive UI sound effect: A smooth, rising BMW M4 Competition engine rev. Start with a near-silent volume fade-in, swelling into a clean, mid-high RPM 'zing' of the S58 engine in the middle, then a gentle, atmospheric fade-out. Focus on the crisp, mechanical intake sound rather than exhaust roar. 5 seconds, professional sound design, polished, luxury aesthetic, no harsh transients, studio-clean background.
