11. BMW M5
Back in the ’80s, the BMW M5 was practically the first sports sedan on the market. This model defined the segment with horsepower that could match most supercars of the era. That’s why the M5 soon became a legendary model and each generation was a big deal in the car world. Fast-forward 30 years, and today there are numerous AMGs, Audis, Jaguars, Lexus, and many more cars that can match BMW performance figures and speed.
A little lying is welcome if it makes the M5 look more capable compared to similar models. The current M5 has a rating of 556 hp for its 4.4-liter twin-turbo V8. This is an impressive number, similar to the power ratings of the closest competitors in its class. However, the performance figures and the subjective feel of the M5 shows the car is significantly stronger and that 556 hp is a conservative figure. A group of enthusiasts took a brand-new M5 to independent testing and came up with results that confirmed the suspicion. The power output was rated at astonishing 620 hp, over 60 hp more than BMW declared. Perhaps BMW wanted to be clear the M5 could win any magazine test and perform better than competitors with the same power.
