- BMW M5 Competition

Here, I am going to present a number of performance cars, sports cars, and supercars that make plenty of more horsepower than advertised. There are plenty of reasons why manufacturers underrate horsepower figures. It could be insurance reasons, fuel economy, tire safety, and many more.

Here are a several cars that produce more power than stated.

Chevrolet Corvette Stingray & Stingray Z51 (495 hp advertised; 550+ hp actual)

The C8 generation of the Corvette nameplate is brand new, and distinct from the generations beforehand. As the "entry-level" version of the model, the Stingray and Stingray Z51 are supposed to make "only" between 490 and 495 horsepower. However, Motor Trend performed a dyno test and revealed the Z51 was actually producing 558 horsepower.

Fairly understandable for a 3600-lb, rear-wheel-drive car delivering similar performance figures to a 2.8-second 0-to-60-mph time and an 11.1-second 1/4-mile time at just under 124 mph. This doesn't make the Stingray on par with the Mercedes-AMG GT or Porsche 911 Carrera, but actually on par with the GT S and Carrera S, as well as the Nissan GT-R and Acura/Honda NSX.

BMW M5 & M5 Competition (592-617 hp rated; 750-800 hp actual)

Being the first all-wheel-drive M5 (F90 is the codename used for the current M5, based on the regular G30 5 Series), it also has the quickest 0-60mph time. At 2.6-2.8 seconds to 60mph with 1/4-mile times dipping into the 10s, the whole car is basically a four-door supercar. Even the "normal" M5 defeats super-sedans from Mercedes-AMG, Audi, Porsche, Tesla, as well as BMW's own M8 Gran Coupe. Dyno tests reveal the M5 models producing as much power to all four wheels as they are advertised to the flywheel by the manufacturer themself.

Dodge's Charger SRT Hellcat, Cadillac's third-generation CTS-V, and even the all-wheel-drive Jaguar XE SV Project 8 all are about a full second slower to both 60 mph and the 1/4-mile than the M5, despite having supposedly higher power-to-weight ratios and more aggressive outlooks. This is where the M5 comes in handy.

ANY 4.4-liter engine producing the twin-turbocharged M5-esque 24.3 psi of boost should have no less than 700 hp. In comparison, the 4.0L AMG E 63S makes barely 21.8 psi, and to make matters worse, the 6.2L Hellcat makes 11.6 psi.

Most McLaren models

McLaren's cars are way more powerful than advertised, as proven hundreds of times. Ferrari, Porsche, and Lamborghini competitors are slower in magazine tests. The McLaren MP4-12C was supposed to be a rival for the 458 Italia, 911 Turbo S, and Gallardo LP570-4 Superleggera. Turned out, it was actually on par with the F12 Berlinetta, 911 GT2 RS, and Aventador LP700-4. The McLaren cars are in a league higher than advertised when it comes to performance; it has been proven by all of the 12C's successors, as well as their smaller siblings.

The hypercars (F1, P1, Senna, Speedtail) are not underrated unlike the more general cars produced by McLaren. Actually, the Senna is slower than the 720S in a straight line.

Toyota Supra (335 hp advertised; 375-425 hp actual)

Like Aunty BMW M5, the new Japanese-German car delivers more power than claimed. It produces as much to the rear wheels as rated at the crank. 0-60mph times are in a range of 3.6-3.8 seconds, or maybe even a rare 3.5. That is INSANE performance for a 3500-lb, RWD sports car. Perfectly slots the Supra between Nissan's 370Z and GT-R, and actually almost on par with Honda/Acura's NSX.

The Nissan GT-R (or Skyline GT-R) used to be underestimated most of its life, but has since kept up with its power figures.
