Ford Mustang Shelby GT350R Test Drive

The Shelby GT350R traded comfort for capability, pairing a naturally aspirated flat-plane V8 with a stripped-down, track-tuned chassis. It became one of the most focused Mustangs Ford has ever built, reviving Carroll Shelby’s original mission decades later. Here’s what set this test-drive-worthy Mustang apart from every other pony car on the lot.

Yeah .. it is probably the greatest mustang ever built…

Ford didn’t build the GT350R for buyers who wanted a comfortable daily driver, and the numbers back that up in ways most road tests don’t fully explain. Engineers borrowed a flat-plane crankshaft layout more common in Italian exotics than American pony cars, chasing a sound and a rev range no factory Mustang had touched before. The GT350R stripped out a rear seat, air conditioning in some trims, and anything else that added weight without adding speed, all in pursuit of shaving tenths off a lap time most owners would never actually chase on a real track. So what does a car built with that kind of obsession feel like from behind the wheel?

A Flat-Plane V8 Borrowed From The Wrong Continent

The GT350R’s heart is a 5.2-liter naturally aspirated V8 nicknamed “Voodoo,” rated at 526 horsepower and 429 lb-ft of torque. Its flat-plane crankshaft design was, at the time, the first of its kind in a mass-production Ford engine, and it let the motor rev far higher than a conventional cross-plane V8 while producing the kind of high-pitched exhaust note usually associated with European supercars. Ford has called it the most powerful naturally aspirated production engine the company has ever built, and behind the wheel that high-revving character is impossible to miss.

Track Focus Over Comfort

Where the standard GT350 tried to balance daily livability with performance, the GT350R leaned hard into the “R” in its name. Carbon fiber wheels, a fixed rear wing, and a stripped interior dropped weight everywhere engineers could find it, and the suspension and aero were tuned for lap times rather than ride comfort. It was Ford’s most track-focused Mustang to date, reviving the spirit Carroll Shelby set out to build with the original 1965 GT350 Competition model. Shelby American has since revived the GT350R nameplate with a modern version pushing well over 800 horsepower, but the original road-legal track car still holds a specific kind of respect among Mustang fans for choosing focus over compromise.

Why Collectors Watch This One Closely

Because the GT350R was built in far smaller numbers than the standard GT350, and because Ford has since moved the Mustang lineup toward electrification and turbocharged power, cars like this one occupy an odd middle ground: modern enough to drive comfortably, focused enough to feel like a genuine analog performance machine. For fans who grew up watching test drives like this one, it’s a reminder that naturally aspirated, manual-only muscle cars didn’t disappear quietly, some of them went out swinging.
