I never get to experience performance the same way people do that live at sea level. I decided to make up a rough set of formulas in order to convert sea level performance to elevation performance. All math is based on my gut/butt feelings, so give them a try!

For naturally aspirated engines:

Total Horsepower Loss = (Horsepower@sealevel) * (0.03) * (Elevation/1000)

Horsepower @ Elevation = (Horsepower@sealvl) - (Total Horsepower Loss)

0-60 mph Time Increase:

1,000 ft = +10% | 2,000 ft = +20% | 5,000 ft = +50%

Example #1: Ferrari F12berlinetta

731 hp @ sealvl, 0-60 mph in 3.1 seconds @ sealvl.

687 hp @ 2,000 ft, 0-60 mph in 3.72 seconds @ 2,000 ft.

621 hp @ 5,000 ft, 0-60 mph in 4.65 seconds @ 5,000 ft.

Example #2: Camaro SS

455 hp @ sealvl, 0-60 mph in 3.9 seconds @ sealvl.

428 hp @ 2000 ft, 0-60 mph in 4.68 seconds @ 2,000 ft.

387 hp @ 5,000 ft, 0-0-60 mph in 5.85 seconds @ 5,000 ft.

For forced induction engines:

Total Horsepower Loss = (Horsepower@sealevel) * (0.015) * (Elevation/1000)

0-60 mph Time Increase:

1,000 ft = +5% | 2,000 ft = +10% | 5,000 ft = +25%

Example #1: Dodge Charger SRT Hellcat

707 hp sealvl, 0-60 mph in 3.4 seconds @sealvl.

686 hp @ 2,000 ft, 0-60 mph in 3.74 seconds @ 2,000ft.

654 hp @ 5,000 ft, 0-60 mph in 4.25 seconds @ 5,000 ft.

Example #2: BMW M4 Coupe

425 hp @ sealvl, 0-60 mph in 3.8 seconds @ sealvl.

412 hp @ 2,000 ft, 0-60 mph in 4.18 seconds @ 2,000 ft.

393 hp @ 5,000 ft, 0-60 mph in 4.75 seconds @ 5,000 ft.

*Note that I drive between 5,000 ft and 7,000 ft above sealevel everyday.

I have zero clue if these are even remotely accurate, but I like them! Go ahead and check out any cars you like, or just ask what car is fast to 60 mph at any elevation. For all of you that say horsepower doesn’t matter, ha! For others that don’t think 6 seconds from 0-60 mph is fast, I would need a 455 hp Camaro to experience 268 hp Camry/ 278 hp Accord acceleration @ sealvl. (Pretending my dataless fake math were actually cromulent, which it isn’t).
