12. Ferrari F40
Back in the late ’80s, the Ferrari F40 was the ultimate supercar. Not only did it look aggressive and gorgeous, but it was also lightning-fast. Ferrari equipped it with the best high-speed components. Under the slick Kevlar body, there was a full lightweight racing chassis and a compact-but-powerful 2.9-liter twin-turbo V8. The official Ferrari horsepower rating was at 471 HP, a high number for the day. However, some journalists who tested the car objected, complaining that the car made way more than that.
Ferrari didn’t address those claims. But recent unofficial testing showed that the car produces between 510 and 530 HP, considerably more than the official ratings. The purpose of hiding that horsepower back in 1988 was to achieve winning numbers in the magazine tests, especially when compared to other similarly-powerful sports cars. Today, the F40 is still fast despite the fact it’s 30 years old. In fact, this car is faster even than the car that replaced it, the F50 featuring a naturally aspirated engine.
