6. Mercury Cougar XR-7

Some people think of a Cougar only as a Mustang with a longer wheelbase and luxury interior. But Mercury’s muscle car was much more than that. With its unique styling and trim, it was an independent force in the muscle car wars of the late ’60s. The ultimate version that perfectly combined muscle car power with luxury was the mighty Cougar XR-7 (via Hemmings).

This model had the 390 V8 engine with 320 HP. But buyers could also opt for the GT package, which included a beefed-up suspension and stronger brakes. Over the years, the Cougar was in the shadow of the Mustang.

5. 2020 Ford Mustang Shelby GT500

It seems that every new generation of the Shelby GT500 pushes the envelope even further. Each model delivers so much power, it’s hard to comprehend. Just look at the latest 2020 model. From the outside, it looks like a menacing Mustang. But the real surprise lies beneath the metal (via JD Power).

The massive 5.2-liter supercharged V8 engine delivers 760 HP and sends it to the rear wheels through an intelligent 10-speed automatic. This interesting combo makes the new GT500 the perfect combination of old-school muscle and modern technology. The result is even more astonishing as it takes just 3.3 seconds to get to 60 mph with a 180-mph top speed.

4. 1969 Pontiac Trans Am

The 1969 Trans Am featured big-block power from the famous 400 V8 engine equipped with the Ram Air III or IV intake system. The difference between those engines was significant since the Ram Air IV featured many improved engine internals and components. But they rated both at 366 HP, which was understated (via Volo).

However, this special version with its signature white paint, blue stripes, and Rally II wheels proved to be a tough seller. Sadly, they only sold 634 Firebird Trans Am. And among those, only eight were convertibles.

3. Chevrolet Camaro Baldwin Motion

Think again if you believe Yenko was the classic Camaro tuner. There were several well-known names in the business, but the most extreme was Baldwin Motion (via Silodrome). Their 427 conversions for the early 1970s models were simply the best. Baldwin Motion installed numerous exceptional performance parts.

They delivered them with a written warranty that the vehicle could achieve 10-second quarter-mile times and produce 500 HP. Today, Baldwin Motion Camaros are highly sought-after and valuable pieces of muscle car history.

2. Ford Mustang Boss 302

The third redesign of the Mustang appeared for the 1969 model year and the car grew again. Ford produced it for only two years in 1969 and 1970. The Boss 302 featured a 302 V8 engine conservatively rated at 290 HP. The real output was closer to the 350 HP mark though (via Ford).

The Boss 302 was a model Ford intended for racing in the Trans-Am championship. Apart from the blackout hood, spoiler on the trunk, and other details, it featured a stiff, track-tuned suspension, a close-ratio gearbox, and a high-revving engine.

1. 1964 Pontiac GTO

A young engineer named John Z. DeLorean thought of a genius idea. He wanted to install a big, powerful 396 V8 into a light, intermediate Tempest two-door body. He knew it was an easy and affordable way to create a true performance machine. For just $295, buyers could get a high-performance 396 V8 with 325 HP in a standard or 348 HP in the famous Tri-Power form (via Muscle Car Facts).

The package included a manual transmission, unique trim, GTO decals, and dual exhaust. And since the car was light, the Tempest GTO delivered a convincing performance. In fact, in 1964, it was one of the quickest American cars on the market. Even Corvette owners weren’t safe from Tempest GTOs lurking at stop lights across the country. The big sales made it clear the GTO was a hit among younger buyers and that a star was born.
