The Porsche Boxster broke from Porsche tradition as the brand’s first production model built around a mid-mounted, water-cooled engine — and its earliest examples carried a cylinder liner flaw serious enough to worry any used buyer. Understanding what Porsche quietly fixed by 2000, and how output climbed across three distinct engine displacements, is useful context even for muscle car fans cross-shopping performance convertibles. Read on for the full mechanical breakdown.
A stock Dodge Challenger Hellcat and a stock Dodge Viper lined up at the WannaGoFast half-mile event at Sulphur Springs Airport, Texas, with barely over a mile per hour separating their best trap speeds. Peter Dunn’s footage reignited the long-running debate over supercharged V8 power versus the Viper’s lighter, more aerodynamic chassis. See which car actually posted the higher number across multiple runs.
Most Mustang GT reviews lean on the window sticker. Landan took LMR’s fresh 2018 Mustang GT straight to a dyno and a quarter-mile track before touching a single bolt, establishing real baseline numbers for a car generation that brought more changes than most buyers realize, an all-new third-generation Coyote V8 and a 10-speed automatic with a dedicated drag mode among them. Watch to see exactly what the numbers showed, and why viewers are still debating them.
Before the 2018 model year, a rendering claiming to reveal a revived three-door Chevrolet Chevelle spread online, complete with invented horsepower figures and a suspiciously plausible price tag. It never happened — Chevrolet never built it, and the Camaro remained the brand’s only performance coupe. Read on to find out what the rumor actually claimed, and why fans wanted a modern Chevelle badly enough to believe it.
A Procharger-blown C7 Stingray and a nitrous-fed, stroked 455 C6 Z06 lined up on a public street in Mexico for a 60-to-190-mph roll race, and the gap between them stayed close for nearly the entire run. Built and driven by 1320video regular StangKiller, the C7 represents the newer chassis and forced-induction school of Corvette tuning, while the C6 leans on raw cubic inches and instant nitrous torque. Watch to see which small-block philosophy actually crosses the line first.
Audi’s R8 shares its bones with the Lamborghini Gallardo and earned praise from Le Mans legend Jacky Ickx before it ever reached production — but the factory version turned out to be just the starting point. German tuner MTM pushed the R8 and its closest sibling in two wildly different directions: a twin-engine Bimoto built from an Audi TT pushing over 1,000 combined horsepower, and a stripped, roll-caged R8 Clubsport capable of 225 mph. Read on to find out how far one platform can really be pushed.
A flyer promising prize money at a March drag shootout doesn’t tell you much on its own — but the track behind it, an NHRA-affiliated eighth-mile strip built for grudge racing and small-tire shootouts, has plenty of story to it. Door-crasher format, cash on the line, and a community that shows up test-and-tune after test-and-tune. Here’s what actually happens when the tree drops and real money’s riding on it.
A Chevy Tahoe that looks like it just left a construction site has been quietly embarrassing sports cars on the street, thanks to a turbocharged LS engine hiding under its unassuming hood. Uploader ThirdHonk catches the truck working over everything from tuner coupes to a supercharged Mustang Cobra, and the reactions from beaten drivers say it all. Watch to see just how thoroughly a sleeper build can turn expectations upside down.
Muscle Car Of The Week usually reaches decades into the past for its features. This week it barely reaches back at all, spotlighting a 2012 Ford Mustang BOSS 302 carrying a designation most viewers have never encountered, Tooling Tryout Number 1, a label reserved for cars used to validate factory production tooling before a model reaches dealers. Built as a direct descendant of the original 1969-1970 BOSS 302, this modern revival turns out to be faster than nearly everything else in the collection. Watch to find out why.
Ford’s own performance chief gave a surprisingly candid answer when asked whether the Ranger Raptor would ever come to America — and it wasn’t a simple yes or no. Jamal Hameedi explained exactly which engines could power a U.S. version, why the diesel it launched with never stood a chance stateside, and why the truck’s suspension impressed him more than its horsepower numbers. Read on to find out what it actually took to bring a Raptor-badged Ranger to American driveways.
Cars.com brought the 2016 Chevrolet Camaro SS, Ford Mustang GT, and Dodge Challenger R/T Scat Pack to Wild Horse Pass Motorsports Park for a week of head-to-head quarter-mile testing. Three different engineering philosophies — high-revving small-displacement, independent-rear-suspension balance, and big-displacement torque — went up against the same stopwatch. The result wasn’t the simple horsepower-wins story some viewers expected. Watch to see which pony car actually got there first.
MotorWeek’s John Davis takes the 2018 Dodge Challenger SRT Demon straight to a drag strip, testing a car SRT engineered from the ground up rather than simply retuning the Hellcat it’s often mistaken for. Four decades into hosting the show, Davis treats it as a milestone episode, and the comments make clear plenty of longtime viewers agree. It’s a car built almost entirely around one number. Watch to see what that number actually is.
John Hennessey’s shop strapped a Shelby GT350R to the dyno wearing its new HPE850 supercharger package, running on Shell V-Power 93 octane, and posted a pull that added 311 rear-wheel horsepower and 193 lb-ft of torque over the car’s naturally aspirated baseline. The resulting graph, a dual-scale readout where the horsepower and torque curves cross around 7,400 rpm, briefly confused viewers before the final number sank in. Watch the pull to see what boosting a flat-plane-crank Voodoo V8 actually looks like on the rollers.
A mildly modified 2004 Dodge SRT-4 takes on a four-speed, 383-powered 1965 Plymouth Belvedere in a street matchup that should have favored the turbocharged compact. More than a decade of comments still argue over who really won, split between Mopar loyalists and turbo-four believers. Watch to see whether raw displacement or forced induction wins the day.
