The Corvette, being the more agile and track-centric of the trio, also has one of the raciest engine barks, from its supercharged 6.2-liter V8. The Shelby’s contribution is much more of a guttural bellow – not quite as loud as the other two, but raspy with a nice burble. In terms of decibels, the Hellcat might have the loudest exhaust shriek, then again if you forced 707 horsepowers into any confined stretch of tubing, they’d come charging out in a hurry.
Admittedly, if you’re into cars like these – you’re not going to be pinching pennies, however the best bang for you buck does come from the Shelby GT500, which retailed for only $55,110 last year. The GT500 is gone from the 2015 model lineup, but worry not, the Shelby comes back in GT350 form for 2016… and it’s bringing with it a flat-plane crank V8. Rematch?
