The Rare Supercharged Mustang That Ruled The Roads Before The GT500
The muscle car’s obituary has been written more than once — and it has been wrong every time. At the turn of the millennium, the genre looked genuinely finished: General Motors pulled the plug on the Camaro and Firebird, the Ford Mustang had been riding the same basic platform since 1979, and Ford had even tried to swap its iconic pony car for the front-wheel-drive Probe. The New York Times declared that ‘Muscle SUVs’ were muscling out muscle cars, and few argued the point.
It looked like Euro-style coupes and SUVs as big as your average apartment were set to inherit the performance car market. The ’90s had produced a handful of interesting American performance cars, but many were underpowered by any serious measure. The early ’90s Chevrolet Camaro RS scraped by with 140 horsepower from a V6, and even the Ford Mustang GT could only muster 215 horsepower from its V8.
What few people saw coming was a full-blown renaissance that would carry the muscle car through the next quarter century. Ford helped ignite the revival with the modern-retro fifth-generation Mustang in 2004, followed by the Dodge Charger in 2006 and the Camaro’s triumphant return in 2010. One of the high-water marks of that new era is the Ford Shelby GT500, with a supercharged 500-horsepower V8 under the hood, proving that the good old days of muscle cars were back for good — and that modern engineering could make them sharper than ever.
But there is one slightly forgotten Mustang that seems to link the old and the new. This is a car that had huge, old-school grunt, yet was designed to be more than a one-trick pony — it is the missing link that rode through the muscle car landscape pretty much alone for a short time. Read on to find out what this rare, supercharged Mustang is all about.

With GM’s muscle cars on the ropes, it would have been easy for Ford to follow suit and quietly wind down its Mustang performance program. The muscle car golden era had ended in the ’70s, and the genre had struggled to find its footing ever since. But Ford wasn’t planning on giving up — quite the opposite. Ford’s John Coletti and his team of engineers at the Special Vehicle Team were clearly smelling blood, because the over-the-hill Mustang was heading to the gym one last time, and this time the bruised heavyweight would be delivering a knockout punch.
How The Supercharged SVT Cobra Got Its ‘Terminator’ Nickname
The car that SVT was working on was nicknamed the ‘Terminator’. Legend has it that Ford wanted to terminate the competition with a killer blow, taking the muscle car segment for itself. Officially titled the Mustang SVT Cobra, the car was built between 2003 and 2004 and was eye-wateringly powerful for the early 2000s. Consider how the supercharged 390-horsepower V8 stacked up against similar cars of the era. The iconic E46 BMW M3 packed just 333 horsepower around the same time, for example.
A Closer Look At The Ford Mustang SVT ‘Terminator’
Much of that extra power came from an Eaton supercharger borrowed from the F-150 Lightning that was bolted onto Ford’s modular 32-valve 4.6-liter V8. The engine produces not just 390 horsepower but also a healthy 390 lb-ft of torque, making this special Mustang seriously quick. The V8 featured a tough cast-iron block with a forged-steel crankshaft, aluminum alloy cylinder heads, forged pistons, and Manley forged “H-beam” connecting rods. To help it rev more freely, SVT also fitted an aluminum flywheel. A water-to-air intercooler further improves performance. There was no automatic gearbox available in the Cobra — a Tremec T-56 six-speed manual was the only shifting option.
Ford Also Reworked The Suspension To Handle The Increase In Power
The suspension was tweaked to deliver more focused handling than lesser Mustangs, with higher spring rates and gas-charged monotube Bilstein dampers. New five-spoke cast-alloy wheels came wrapped in 275/40ZR-17 Goodyear Eagle F1 rubber. The performance figures are formidable. The car reaches 60 mph in just 4.5 seconds, and 100 mph arrives in 10.4 seconds. The quarter mile is dispatched in 12.9 seconds at 111 mph, with a top speed electronically limited to 155 mph. That was enough for the supercharged Cobra to out-drag the BMW M3 of the time — the German sports coupe needed 4.8 seconds to reach 60 mph and 13.5 seconds to complete the standing quarter mile.
Here’s How Rare The Mustang SVT Cobra Is
By Mustang standards, the SVT Cobra is a very rare car indeed — though perhaps not by, say, Aston Martin standards. Ford managed to shift 140,350 Mustangs in 2003, according to Cjponyparts.com, but just 8,394 of them were Cobra coupes, with another 5,082 Cobra convertibles (Hemmings). In 2004, production dropped further to 3,768 coupes and 1,896 convertibles. When new, the Cobra was priced at $34,750 for the coupe and $38,999 for the convertible — undercutting the BMW M3 by more than $10,000. Today, the Cobra is firmly on the collectible radar, with values to match, says Hemmings. Read on to find out how much to pay.
