Buick spent most of the 1980s making comfortable sedans and then, in its final year, built a turbocharged six-cylinder that ran a 13.2-second quarter and beat V8s that cost far more. The 1987 Grand National and the 547 GNX units that followed it were the last of the line, assembled in part by an outside performance house, and factory rated at a number almost nobody believed. Read on for what separated a WE4 from a GNX, and what a $35 option got you.
One of the actual Dodge Chargers used on screen by Dominic Toretto in the original Fast and the Furious now belongs to an Italian collector — and in 2015, he did something most owners of movie-used muscle cars never risk. He ran it down a real quarter-mile at Rivanazzano’s dragstrip in Italy. The pass has racked up nearly six million views since, mostly from people who can’t believe he actually did it.
Bobby at Alloway’s Hot Rod Shop says there are only two engines like this one anywhere in the world, and it lives under the hood of a 1955 Plymouth Savoy that looks almost stock at first glance. Between the Art Morrison chassis, a custom interior from Pro Auto Custom Interiors’ Steve Holcomb, and that over-500-cubic-inch polished aluminum Hemi, this build hides serious ambition behind restrained styling. Watch to see how ScottieDTV’s camera uncovers what makes it so rare.
Stock-motor, stock-turbo quarter-mile racing is a surprisingly competitive corner of the Porsche 911 world, where a handful of tenths separates casual bragging rights from an actual record. This twin-turbo 911 leans on nitrous and drag radials rather than internal engine work to chase that record — a very different game than the heavily built cars dominating the outright quarter-mile books.
1974 marked the final year Plymouth built the Road Runner on its original mid-size platform, with engine options still ranging from a mild 318 up to a 440 big block wearing GTX badges. Production had fallen to 11,555 cars, down from 19,056 the year before, as the muscle car era wound down. The Road Runner nameplate held on one more year on the larger Fury-based B-body before being reduced to a Volare trim package in 1976.
Tom Lembeck has owned this 1970 Plymouth Superbird — one of roughly 135 built with the 426 Hemi — since 2007, and Lou Costabile catches up with him in Chicago for ‘My Car Story.’ Finished in Plymouth’s High Impact Vitamin C orange, the car draws no shortage of comments calling it the most memorable muscle car of the 1970s. Watch to hear Lembeck’s decade-plus history with one of Mopar’s rarest homologation specials.
This video ranks five of the greatest V8 engines from the golden era of American muscle cars, opening with a key distinction: the 426 Street Hemi’s factory-warrantied 10.25:1 compression versus its race-only cousin. One commenter adds real-world proof of the era’s staying power — a 1970 Mustang Mach I he’s owned since 1977, now making 425 horsepower after a 351 Cleveland rebuild. See which five engines made the list.
Bond’s DB5 and Dom Toretto’s Charger are not the only movie muscle cars worth remembering. A black Trans Am and a customized Mustang fastback both left just as big a mark on car culture, one by boosting real-world sales and the other by spawning an entire tribute-car industry. Here is the rest of the list.
Manual transmission drivers have argued for decades about whether engine braking secretly wears out a clutch, and Jason Fenske of Engineering Explained finally settles it with real mechanical reasoning instead of garage folklore. The answer involves rev matching, brake pad life, and fuel cutoff systems most drivers never think about. Nearly three million views later, the comment section is still arguing anyway.
A German Formula One driver once drove a Porsche 550 Spyder underneath a closed railway crossing gate during a race, without slowing down. That is how low the car sat, and part of why a 1,498cc four-cylinder could humiliate machinery with twice the displacement. Then James Dean bought chassis number 55, had a name painted on the trunk lid, and turned a race car into something else entirely. Read on for the whole story.
GM design chief Bill Mitchell wanted a full-size luxury coupe with the drama of a 1930s speedster, and the boattail Riviera is what happened. He modeled its tapered tail on the 1963 Corvette Sting Ray he considered his masterpiece, then watched the shape get stretched across a much larger body. Mitchell himself later admitted the result looked less like a speedboat than a tugboat. This 1973 example, the last year of the design, went through Count’s Kustoms.
A random online post about a car sitting in someone’s barn led The Auto Archaeologist to a 1967 Mercury Comet Caliente most muscle car fans have never heard of, let alone seen. This particular example carries the R-code designation, meaning a factory 427 with dual four-barrels and a four-speed manual, verified in an original Hot Rod magazine feature. Even dedicated Mercury enthusiasts often assume this configuration is more legend than reality. Watch to see what a genuine, forgotten piece of Mercury muscle car history looks like today.
Corvette interiors are the part of a restoration most owners rush and most judges study first. Matching a factory stitch pattern, sourcing correct-grain material, and repairing the seat structure underneath are what separate a correct interior from an expensive approximation. None of it requires a professional shop, but all of it requires decisions made before the first staple comes out. Here is what actually goes wrong, and how to avoid it.
A rare 425-horsepower 426 Hemi Road Runner — 1 of just 287 built in 1970 — takes on a 440 Six Pack Challenger in a quarter-mile grudge match that Mopar fans still can’t agree on decades later. Both cars sold for around $4,000 new and are now worth 20 to 40 times that. Watch to see which factory legend crosses the line first.
210 episodes into covering the Brothers Collection, Muscle Car of the Week finally ranks the convertibles — pulling from a 1967 Mustang K-code, a 1964 Plymouth Satellite 426 Wedge, a fuel-injected 1959 Corvette, and a 440 Six Barrel ‘Cuda in Tor-Red. Each car represents a different era and manufacturer’s approach to open-top American performance. The comments are already split over which one deserves the top spot. Watch to see the full lineup and decide which convertible you’d pick.
