Top Gear Tests the Mustang GTD and Corvette ZR1

The most extreme American cars ever built: Mustang GTD vs. Corvette ZR1

Top Gear staged its most extreme American head-to-head yet at the Ten Tenths Motor Club in Charlotte, North Carolina, pitting the Ford Mustang GTD against the Chevrolet Corvette ZR1. Both are Nรผrburgring-developed, sub-seven-minute machines with genuine motorsport intent, and both represent a radical evolution of their nameplates.

On paper, the Mustang GTD arrives with serious race-car credibility. Built by Multimatic, it uses a 5.2-liter supercharged V8 producing 815 hp, extensive aero generating 600 kg of downforce at 155 mph, and a curb weight near 1,930 kg.

The Corvette ZR1 counters with brute force efficiency: a 5.5-liter twin-turbo V8 delivering 1,064 hpโ€”the most powerful production V8 everโ€”less downforce overall but at far higher speeds, and a significantly lighter package.

On track, the differences are immediate. The Mustang feels like a homologation specialโ€”ultra-stiff, hugely stable under braking, and defined by confidence at high speed. Its adjustability, braking performance, and downforce make it feel closer to a GT3 race car than a roadgoing Mustang. Despite its weight, it delivers consistency, precision, and trust.

The Corvette, by contrast, feels more like an exceptionally sorted road car with explosive pace. Itโ€™s less locked down, more fluid, and lighter on its feet, with immense traction and staggering straight-line speed. While not as stable under braking as the GTD, it rewards commitment and feels devastatingly fast everywhere. The stopwatch settled the debate. The Mustang GTD set a 1:15.61 lap, but the Corvette ZR1 obliterated it with a 1:12.97โ€”over two and a half seconds quicker on a short, technical circuit.
