11 Cars That Make Way More Horsepower Than AdvertisedSometimes, automakers don't reveal the true potential of their finest cars.

The Corvette L88 was a factory-built race car that advertised an output of 435 horsepower, but likely made at least 100 more than that. Corvette godfather Zora Arkus-Duntov didn't want the L88 in the hands of the general public, so the numbers were dramatically downplayed to keep the car a racers-only secret.
Ferrari F40Officially, Ferrari claims the F40 makes 478 horsepower. Unofficially, many enthusiasts and journalists who've tested the F40 believe it makes over 500 horsepower—which may explain why it's much quicker than its successor, the F50.
Ford Mustang Boss 429Built to get Ford's biggest V-8 homologated to race in NASCAR, the Mustang Boss 429 was hilariously underrated by the factory. Ford advertised a stout 375 horsepower, but as Hemmings says, "if you take that 375 hp power rating and replace that three with a four, you're a little closer to the truth."
1969 Pontiac GTO The JudgeThe Judge was the most powerful GTO you could buy in 1969, though according to Pontiac it only made 10 more horsepower than the next most powerful variant. Except not really: Pontiac executives apparently told a magazine testing a Judge that the 370 number was entirely made up, thanks to GM's policy at the time assigning horsepower ratings based on the weight of the car. Figure The Judge made at least 30 more horses than The General claimed.
BMW M5It's widely known that BMW is rather conservative with the performance specs it publicizes, especially with its performance cars. BMW advertises the current M5 Competition as having 617 horsepower at the crank, but independent dyno testing reveals it's closer to 700. That explains why the 0-60 sprint happens in less than three seconds.
Ford Mustang Shelby GT350The Mustang Shelby GT350 is powered by one of the coolest modern engines: A 5.2-liter naturally aspirated V-8 with a flat-plane crank, allowing it to rev past 8000 rpm. Ford estimates maximum horsepower at 526 ponies, but in reality, it's making closer to 600. Not bad for something without forced induction.
