Chevy's whistled audio mark is unusual as, unlike many other brands, it sometimes plays at the start of an ad rather than the end (although it plays at the end of the video above).
The logo scores well in the "authentic" (78), "confident" (78), "approachable" (76), "trustworthy" (76) and "reputable" categories.
However, it underperformed in the "excited" attribute, scoring just 68.
