The Challenger SRT Demon’s launch procedure reads like a checklist from a flight manual: line lock, brake, burnout, stage, release. Behind it sits a system that builds boost before the car moves, a set of factory drag radials, and an air conditioning circuit repurposed to chill intake air. The front wheels leave the ground by nearly three feet. Read on for how Dodge got there, and what the car is like the rest of the time.
In November 2016, a Ford F-450 reclaimed the Guinness World Record for Largest Flag Pulled by a Moving Vehicle, towing a 4,124-square-foot American flag around Homestead-Miami Speedway to beat a Chevrolet Silverado’s earlier record by nearly 1,000 square feet. The Super Duty’s 440-horsepower, 925-lb-ft Power Stroke diesel V-8 got credit for the pull, which stretched well past the minimum distance required to set the new mark. It’s proof that truck bragging rights aren’t only settled at the drag strip.
In 2015, a Wisconsin trapper named John Oens found himself face to face with a fully grown timber wolf, one leg caught in a trap. Instead of a catch pole, he used a scrap of plywood with a hole cut through it, and the wolf barely fought back. Watch how he pulled off a release so clean it is still racking up views nearly a decade later.
A 1976 Dodge Aspen R/T doesn’t look like a factory Super Bee — because in the U.S., that car never existed. Chrysler kept the nameplate alive four extra years exclusively for Mexico, grafting a Dodge front end to a Plymouth’s tail and fitting an engine American buyers couldn’t get. One grandfather-grandson build project set out to recreate it from scratch, one badge and taillight at a time.
The Lamborghini Gallardo became the brands best-selling model ever, with over 14,000 built between 2003 and 2013, by offering something Lamborghini rarely had: real usability. This 2004 examples 500-horsepower V10 and dual-transmission choice show exactly why. Here are the numbers behind the car that redefined what a Lamborghini could be.
Two Highland Green Mustangs were built for the chase scene in Bullitt, and for fifty years the accepted story was that only one survived. Both turned out to be alive. This is what Ford actually put in an S-code 390 GT fastback, what Max Balchowsky changed before the cameras rolled, how fast these cars really were once the stopwatch came out, and what happened when the hero car finally crossed an auction block in 2020.
The Auto Rules wanted to answer a question every backyard mechanic has joked about: can you supercharge an engine with a leaf blower? The answer, tested on a 5.4-liter V8, isn’t a simple yes or no — there’s no real boost involved, yet the dyno still showed a gain. Commenters are already lobbying for a turbocharged leaf blower as the sequel. Watch to see exactly how many horsepower a cheap tool can buy.
The 1969 Plymouth Road Runner was the year the budget muscle car formula worked exactly as intended, and 84,420 buyers proved it. Behind the cartoon horn sat an exclusive 383 four-barrel making 335 horsepower, built from parts borrowed off the far more expensive 440. Here is what Plymouth actually did to that engine, why air-conditioned cars got a different one, and what separates a real 383 four-speed car from a badge job today.
GM’s 1971 switch to low-lead fuel dropped the Buick 455’s compression from 10.0:1 to 8.5:1, and the Stage 1 rating fell from 360 horsepower to 345. Buick built the car anyway, with a hotter camshaft, larger valves, a recalibrated Quadrajet and 3.42 Positraction as standard, and roughly 81 of them left the factory as convertibles. Period tests still recorded mid-13-second quarter miles. Read on for what a genuine Stage 1 has to prove before you write the check.
Buick built fewer than 700 examples of the original 1970 GSX, a Grand Sport-based muscle car so quick it later sparked a magazine controversy over whether it actually out-accelerated the Hemi ‘Cuda. Backed by slogans like A Brand New Brand of Buick, the GSX carried Buick’s big-block ambitions through 1974, when the 455 V8 was dropped for good. Read on to see how Buick’s rarest muscle car nearly out-ran a Mopar legend.
A factory-built Dodge Demon, engineered from the ground up to dominate the quarter mile, takes on a Tesla Model S P100D in Ludicrous mode, on a public street instead of a prepped drag strip. The Demon’s supercharged Hemi fights front wheel lift off the line while the Tesla’s instant electric torque needs no warm-up at all. Viewers were quick to point out the street surface never gave the Demon’s drag radials a fair shot. Watch to see which car actually gets to the end first.
Back-to-back fuel crises in 1973 and 1979 forced Pontiac to rethink the Trans-Am from the ground up, and the result was a 1982 redesign built almost entirely around wind tunnel data — roughly 500 pounds lighter, capable of 34 mpg with the four-cylinder engine, and styled with hidden headlights and a frameless rear window. Read on to see how that fuel-crisis compromise eventually turned into the fastest production car in North America.
Buick built well over a hundred thousand Special sedans for 1953, and yet this ordinary four-door quietly marked the end of an engine era nobody at the time realized was closing. A brand-new V8 was already going into more than half of Buick’s output that year, just not into this car. Here is why Buick held its most affordable model back, and what else changed underneath in the same twelve months.
Plymouth’s answer to the Ford Mustang did not just need to look sporty; it needed to earn the title, and the 1965 Formula S package was how it happened. A 235 horsepower Commando V8 paired with upgraded suspension and a factory tachometer turned an ordinary Barracuda into a genuine performer. Fewer than three thousand buyers ordered it that year, so why did the option that made the car worth having stay so rare?
Ford beat Chevrolet to market by six months and Plymouth by nine with the slab-sided 1949 Custom, and this pale yellow Gateway Classic Cars convertible carries the last of Ford’s legendary flathead V8s. Between the shoebox styling and the fold-down top, it’s a genuine turning point in postwar design. Read on to see what made Ford race to get there first.
