 The decade of the 1970s proved detrimental for American muscle cars. With the comprehensive implementation of the Clean Air Act in 1970, rigorous emission regulations were enforced. Consequently, U.S. automobile manufacturers had to shift away from their reliance on large-displacement engines towards developing smaller, fuel-efficient alternatives instead. Nonetheless, despite these changes, the decline of the classic American muscle car wasn’t immediate; hence, throughout much of the '70s, this iconic horsepower remained very much alive and well.

<p>
 Let’s begin with the single Ford on the list, the 1970 Ford Torino Cobra. This model was released a few years prior to the "
 Malaise Era
 started up more quickly and outperformed similar Mustangs from the early 1970s. During this period, Ford was producing bigger vehicles, with the Torino being among the largest within its class. The larger mid-size model came equipped with Ford’s 429 cubic-inch V8 engine, which had taken over as the power source.
 he legendary 428
 All models were equipped with this engine, however, the Cobra edition received an enhanced version capable of reaching 370 horsepower.
</p>
<p>
 Consequently, the Torino Cobra was quite swift. It reached 60 miles per hour in about 5.8 seconds and completed the quarter-mile run in exactly 14 seconds. This performance wasn’t too shabby considering when it was made. It’s intriguing to think about just how much quicker it might have been had it not been significantly bigger than its predecessor. Regardless of its size, this vehicle held its own during its time and was fast enough to earn its spot among others.
</p>
<p>
 The popularity of the Torino was significant enough that it led Ford to discontinue the Fairlane brand in favor of it. However, emission regulations ultimately brought an end to the Torino. The model's production ceased in 1976.

<h2>
 1972 Jaguar E-Type Series 3 with V12 Engine
</h2>

<p>
 In 1972, the Jaguar E-Type Series III doesn’t immediately bring to mind classic American muscle cars. Nevertheless, this vehicle boasted an equally powerful engine and impressive speed. Throughout the 1960s, the Jaguar E-Type ranked among the top coveted high-performance vehicles, earning praise from Enzo Ferrari himself who dubbed it “the most beautiful car ever made.” The E-Type Series III debuted in 1971 and possessed just as much power as any other model listed under the category of muscle cars.
</p>
<p>
 The E-Type Series II was quite speedy, achieving 0 to 60 mph in 5.7 seconds and completing a quarter-mile run in 14.2 seconds. However, these figures can fluctuate based on various factors.
 who you ask
 So, we opted for the quickest one available. The Jaguar was equipped with a massive 5.7-liter V12 engine that might not have excelled in drag races, but it could hit a top speed of 145 MPH, which was impressive back then.
</p>
<p>
 Jaguar continued production of the Series III up until 1975, a detail that will recur throughout this piece. After discontinuing the Series III, Jaguar shifted focus to different ventures and did not manufacture another E-Type model.

<h2>
 1970 Plymouth Road Runner with Hemi
</h2>
<img data-document-id="cms/api/amp/image/AA1B1FvC" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1FvC.jpg"/>
<p>
 The 1970 Plymouth Road Runner Hemi embodies all the characteristics of a quintessential American muscle car. It was large, notably speedy, and undeniably had the looks to match. Underneath its exterior lay one of the
 top engines that Dodge has ever produced
 , the Chrysler 426 Hemi V8 powers the Road Runner, delivering an impressive output of 425 horsepower and 490 pound-feet of torque, making it one of the most powerful vehicles of its time. Interestingly, the scoop on the hood was functional, capable of being activated from inside the car.
</p>
<p>
 Thanks to Dodge’s potent 426 Hemi V8 engine, it's not surprising that this vehicle made the cut. According to various reports, it accelerated from zero to 60 miles per hour in approximately 5.5 to 5.6 seconds and completed a quarter-mile run in about 13.5 to 13.6 seconds, varying slightly based on different sources. The car was governed, making precise top-speed figures hard to come by; however, with specifications akin to those of the standard-engine-equipped Plymouth Road Runner Superbird—which had an unregulated maximum speed of 142 mph—it likely reached comparable velocities when unrestricted.
</p>
<p>
 The Road Runner — named for the famous bird from "Looney Tunes" — was a hit for Plymouth in the late 60s and early 70s. However, as the muscle car era wound down, so too did the Road Runner. Its final year was 1980.
</p>
<h2>
 1970 Plymouth Superbird
</h2>
<img data-document-id="cms/api/amp/image/AA1B1DhP" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1DhP.jpg"/>
<p>
 When discussing the Plymouth Superbird, it stands out as one of the quickest vehicles from the 1970s. Although it shared many characteristics with the Plymouth Road Runner Hemi, they had distinct variations. The production period for this model was limited to just one year during which Plymouth manufactured merely 1,935 units. Consequently, it ranks among the most scarce muscle cars of that era. It’s believed that the design incorporated elements from both the Road Runner and the Dodge Charger Daytona, evident through its large wing at the back. Three powertrain choices were available: a 426 Hemi akin to what you'd find in the Road Runner, along with two variants of a slightly beefier 440 cubic-inch V8 motor.
</p>
<p>
 You might think that an automobile featuring such a preposterous spoiler would accelerate quite rapidly, and the Superbird certainly lived up to expectations. It achieved 60 miles per hour in just 5.5 seconds and completed a quarter-mile sprint in 13.5 seconds. Although comparable to the RoadRunner, it demonstrated superior performance, particularly during shorter distance races like the quarter mile, contingent upon which engine variant you chose. However, the true highlight of the Superbird lay in its top-end velocity; capable of exceeding speeds over 200 miles per hour, it was clearly designed for high-speed competition.
</p>
<p>
 Sadly, NASCAR implemented new regulations for vehicles such as the Superbird, and Plymouth ceased production of the car one year thereafter.
</p>
<h2>
 1970 Buick GSX Stage-1
</h2>
<img data-document-id="cms/api/amp/image/AA1B1yDm" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1yDm.jpg"/>
<p>
 While Buick may not have been known for being a major player in the muscle car scene, they certainly had their share of impressive models. One standout example from this lineup is the 1970 Buick GSX Stage-1. This model fit seamlessly among other iconic muscle cars of the '70s both aesthetically and mechanically. Underneath its hood lies a powerful 455 cubic-inch V8 engine capable of generating 360 horsepower along with an astounding 510 pound-feet of torque. Such power output makes it particularly suited for those who enjoy drag racing should they decide to own one of these vehicles.
</p>
<p>
 The Buick GSX Stage-1 matches the performance of both the Plymouth Road Runner and Super when accelerating from 0 to 60 mph in 5.5 seconds. Nevertheless, it can complete the quarter-mile run even quicker at 13.38 seconds. This torque proves beneficial. These figures are sourced from an
 issue of Overdrive Magazine
 From those times long ago, so consider them as such. Other estimations suggest the car is a
 little slower
 but not by much.
</p>
<p>
 It should be remembered that all the aforementioned figures pertain to the automatic transmission variant of the vehicle. Opting for the manual transmission would have increased each measurement by several-tenths-of-a-second. Therefore, to achieve the quickest available Buick GSX Stage-1, an automatic transmission was necessary.
</p>
<h2>
 1970 Chevelle SS 454
</h2>
<img data-document-id="cms/api/amp/image/AA1B1FvG" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1FvG.jpg"/>
<p>
 To keep pace with its higher-end counterpart, Chevrolet featured several swift vehicles during the 1970s. A prime illustration would be the Chevelle SS 454. True to its designation, this model was equipped with Chevy’s impressive LS6 V8 engine, offering a displacement of 454 cubic inches and capable of generating up to an astounding 450 horsepower within the confines of a Chevelle. Although it offered alternative powertrain choices, those seeking top-tier acceleration opted for the potent 454 engine. Similar to many automotive manufacturers at the time, Chevrolet reveled in what were effectively the twilight years of the classic American muscle car era.
</p>
<p>
 Thanks to its powerful engine, the Chevelle was notably quick. It accelerated from 0 to 60 MPH in just 5.4 seconds, with driver John Dianna achieving an impressive quarter-mile time of 13.44 seconds during testing at that period.
 Motortrend
 , Dianna managed to achieve similar results consistently, which makes us confident enough to say it can reach that speed. Nevertheless, for fairness, Motortrend acknowledged that certain adjustments were made, including taking out the air filter element.
</p>
<p>
 The Chevelle faced a protracted demise due to the Clean Air Act. Chevrolet ceased production of the vehicle in 1977. At this point, it only managed to produce a mere 145 horsepower and had become but a shadow of its once-formidable performance capabilities.
</p>
<h2>
 1970 Pontiac Trans Am
</h2>
<img data-document-id="cms/api/amp/image/AA1B1Hyf" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1Hyf.jpg"/>
<p>
 In the 1970 lineup, the Pontiac Trans Am stood out as the quickest model available during that decade. Tracking down precise performance figures proved quite challenging. This car offered two fairly potent engine choices with not much difference in their acceleration capabilities. The primary option was a 400-cubic-inch Ram V8 delivering 345 horsepower along with decent quarter-mile times. Nonetheless, just 88 units were equipped with an even more powerful variant known as the Ram Air IV, boasting an output of 370 horsepower.
</p>
<p>
 The two engines were fast, though the Ram Air IV was faster. According to most accounts, a Trans Am equipped with this engine could accelerate to 60 mph in approximately 5.4 seconds and complete a quarter-mile run in about 13.9 seconds. It’s worth noting these figures are largely based on estimations.
 some car authorities
 The vehicle could achieve zero to sixty mph in under six seconds and cover a quarter-mile in less than fourteen seconds, though precise figures were not commonly provided. In the least favorable scenario, the quarter-mile run would take around 14.1 seconds.
</p>
<p>
 In contrast to most car manufacturers, which abandoned their muscle cars during the '70s, Pontiac continued with them.

 For several more decades before ultimately retiring it in 2002. The last version recaptured some of that muscle car charm for one final performance prior to being discontinued.

<h2>
 1971 Chevrolet Corvette LS5 and LS6
</h2>
<img data-document-id="cms/api/amp/image/AA1B1yDn" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1yDn.jpg"/>
<p>
 Including a Corvette is essential for any muscle car lineup, and it rightfully takes a prominent spot near the top. In this segment, we will discuss two specific models: the LS5 and the LS6. These variants primarily differ in their engine configurations. The LS5 came equipped with Chevrolet’s 454 cubic-inch LS5 V8, delivering 365 horsepower. On the other hand, the LS6 featured an enhanced version of the same displacement—Chevrolet’s 454 cubic-inch V8—but produced a robust 425 horsepower instead.
</p>
<p>
 The twins were capable of competing almost anywhere, yet the LS6 had a clear speed advantage. The LS5 could accelerate from 0 to 60 mph in 5.3 seconds and complete a quarter-mile run in approximately 14.1 seconds. This timing placed it at 0.3 seconds behind the LS6’s quicker 5-second 0-to-60-mph acceleration and its even swifter 13.72-second quarter-mile finish. With minor modifications, the latter vehicle might achieve times under 13 seconds for the quarter mile with minimal trouble. Although logically, the LS6 ought to rank above, their overall similarity justified listing both models together.
</p>
<p>
 Among all the cars mentioned, the gas-powered Corvette stands out as one of the few brands from the past that has endured until today. Modern iterations continue this legacy.

<h2>
 1971 Dodge Challenger R/T 426
</h2>
<img data-document-id="cms/api/amp/image/AA1B1tG5" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1tG5.jpg"/>
<p>
 The last three muscle cars on our list include two from Dodge, indicating that they were among the speediest during the 1970s. This particular model features a refined iteration of Dodge’s powerful 426 Hemi V8, differing somewhat from the versions found in Plymouth vehicles discussed previously. Additionally, there was another option: the 440 cubic-inch six-pack V8 with 385 horsepower. However, for this discussion, we will focus specifically on the variant equipped with the iconic 426 Hemi engine.
</p>
<p>
 That vehicle was incredibly swift. It could accelerate from zero to 60 miles per hour in 5.2 seconds and complete a quarter-mile run in roughly 13.3 seconds. We discovered some references indicating that the car could achieve zero to 60 miles per hour in
 5 seconds flat
 However, we couldn't confirm whether that specific model had been altered or not. Regardless, the Challenger could easily outperform nearly every other vehicle in its class.
</p>
<p>
 The Challenger would endure the difficult times and regain its prominence during the 2000s and 2010s. Nonetheless, Dodge eventually

 It was substituted with the Charger, available now in both 2-door and 4-door versions.
</p>
<h2>
 1971 De Tomaso Pantera
</h2>
<img data-document-id="cms/api/amp/image/AA1B1FvK" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1FvK.jpg"/>
<p>
 In 1971, the De Tomaso Pantera stood out amidst the realm of muscle cars despite being technically classified under Italian automakers rather than categorized strictly as an American muscle vehicle. This distinction arose because Ford acquired 84% ownership and directed the production of this particular model equipped with a Ford engine—the Pantera. At its core lay Ford’s 351 cubic-inch Cleveland V-8, marketed then as their “Italian” V-8. With outputs reaching up to 326 horsepower and delivering 344 foot-pounds of torque—numbers that might appear modest today—it managed impressive performance due to weighing just about 3,131 pounds. To put this into perspective, consider that this weight figure places it approximately 700 pounds lighter compared to the aforementioned Dodge Challenger.
</p>
<p>
 Consequently, this vehicle was swift. It could accelerate from 0 to 60 miles per hour within a range of 5.0 to 5.5 seconds. In addition, it performed admirably in the quarter-mile run, completing it in roughly 13.3 seconds, with some minor variations. What set it apart from typical vehicles was its mid-engine design; unlike conventional models, the Pantera had an architecture typically found in sports cars rather than muscle cars. Thus, even though it boasted American power, it simultaneously fell into the category of a sports car due to its technical specifications.
</p>
<p>
 De Tomaso kept producing the Pantera until their partnership with Ford ended in 1974. The firm ultimately went bankrupt prior to being acquired by China’s Ideal TeamVenture in 2015.
</p>
<h2>
 1970 Dodge Charger Daytona R/T
</h2>
<img data-document-id="cms/api/amp/image/AA1B1DhU" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1DhU.jpg"/>
<p>
 The 1970 Dodge Charger Daytona R/T stood out as an extraordinary vehicle. Designed specifically for high-speed races, its prominent spoiler clearly signaled its performance intentions. Similar to the Challenger, this model featured the powerful 426 Hemi engine, further cementing the reputation of this motor. With only around 503 units manufactured, it remained quite rare and sought after.
 one of the most uncommon vehicles on this roster
 as well.
</p>
<p>
 Let’s cut to the chase. The vehicle accelerated from 0 to 60 mph in roughly 5.1 seconds and completed a quarter-mile run in around 13 seconds. While this made it competitive on the dragstrip, it didn’t always come out as the quickest one there. However, the Daytona truly shone on the racecourse. Buddy Baker shattered records by hitting speeds above 200 mph at the Alabama International Motor Speedway—marking the first time anyone had broken the 200 mph mark at the Indianapolis 500. On that particular day, it left all others behind with a speed advantage of approximately 30 mph.
</p>
<p>
 NASCAR proceeded to overhaul its regulations, prohibiting aero cars such as the Daytona and the previously mentioned Superbird. Consequently, production of these vehicles was discontinued by both manufacturers by 1971. However, for some time, those models were practically airborne.
</p>
<h2>
 Sports cars began dominating in the 1970s.
</h2>
<img data-document-id="cms/api/amp/image/AA1B1wmt" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1wmt.jpg"/>
<p>
 Given the strict emission regulations at the time, large V8 engines faced significant challenges. Despite automakers' efforts, by the end of the decade, their vehicles produced less than 150 horsepower. Recovery wouldn’t come for about ten years. During this period, however, the sports car market began thriving instead. These automobiles featured compact, fuel-efficient motors; some even incorporated turbochargers. When combined with remarkably lightweight designs, these cars managed to carry forward the legacy of muscle cars.
</p>
<p>
 One outstanding example from 1978 is the Porsche 930 Turbo. This vehicle had a weight of approximately 2,800 pounds and featured a powerful 261 horsepower turbocharged flat-six engine delivering up to 291 lb-ft of torque, paired with a four-speed manual gearbox. It accelerated impressively, reaching 60 miles per hour within just 4.9 seconds and completing the quarter-mile run in 13.7 seconds at a speed of around 104 mph. In contrast, muscle cars like Chevrolet Chevelle relied on less potent engines—around 150 horsepower for their V8 units—highlighting how advanced these sports vehicles truly were compared to others during that era.
</p>
<p>
 Nowadays, numerous turbocharged four-cylinder engines produce as much power as Porsche models from the 1970s did. In fact, my modified Honda Accord with a 2.0-liter turbo engine matches those performance metrics and can run a quarter-mile in just 5.5 seconds. That’s quite impressive for such a typical vehicle equipped with an enhanced motor.
</p>
<h2>
 Methodology
</h2>
<img data-document-id="cms/api/amp/image/AA1B1DhV" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1B1DhV.jpg"/>
<p>
 In compiling this list, our focus was mainly on drag racing. This activity gained significant popularity among car aficionados during the '50s, '60s, and '70s, often depicted in movies through scenes of impromptu street races. Given these references, it became evident that measuring performance using zero-to-60 miles per hour acceleration times and quarter-mile runs would be straightforward indicators for comparison purposes. Therefore, we ranked the vehicles based largely on their rapidity off the line—specifically, those achieving faster zero-to-60 mph times first. In cases where multiple models shared similar figures, additional criteria such as quarter-mile completion times and peak velocities served as decisive factors.
</p>
<p>
 We gathered timing data from various sources, considering factors such as driver expertise, altitude, and external temperatures, which can influence overall performance. For instance, a vehicle tested at sea level on a 70-degree day will likely record different timings compared to another running multiple thousands of feet higher under cooler conditions. Typically, we opted for the quickest times available.
</p>
<p>
 The sole exemption was the Dodge Charger Daytona R/T. We placed that thing right at the top of our list since despite having impressive drag racing statistics, it also had an unmistakable talent for maintaining high speeds over long distances. Placing a record-holder at positions two or three just wouldn’t have been appropriate.
