When Pontiac revived the GTO in 2004, engineers pulled a real 1964 GTO out of their own historical collection just to benchmark its exhaust note and tune the new car to match it.

Pontiac's ads for this GTO showed someone taking a hammer to the front bumper — the body-color Endura cover was designed to no-show low-speed hits, and Pontiac loved proving it on camera.
The GTO's name was a cheeky nod to Ferrari's 250 GTO, but Pontiac took the joke further than anyone expected and actually got it FIA-homologated for European sports car racing.
Rivals
Same body, same money, other badges — tap any card to flip.
The Celica XX, Japan's name for the A60 Supra, introduced the world's first in-car navigation computer.
The CTR Anniversary looks like a 911 but Ruf built its carbon monocoque from scratch, no Porsche body underneath.
The 228's coupe styling hides a sedan underneath: Maserati stretched it onto the longer four-door Biturbo chassis to make room for its biggest V6, which is literally where the name comes from — 2-door, 2.8 litre.
Switching to fuel injection let this V8 finally shed its trademark bonnet bulge — and only 405 of these flat-hooded Series 5 cars were built before the whole model retired in 1989.
Japanese buyers got a secret weapon in their MX-6 — the JDM-only KL-ZE V6 made about 40 more horsepower than the engine sold in the exact same car in North America.
An American tuner, Callaway Cars, built twin-turbo conversions of the GTV6 that boosted its V6 by fifty percent to 230 hp — turning Alfa's grand tourer into something far quicker than the factory ever intended.

A product of the DaimlerChrysler merger, the Crossfire shares 80% of its parts with the Mercedes-Benz SLK — German bones under American badges.
