The Sl600 has 510 HP and not 493???!!

Why does everyone say that the HP on the R230 Sl600’s are 493?

Even a google search on that spec shows that result. But It’s incorrect…

Look at this old brochure from Mercedes themselves. You can clearly read that their Mercedes V12 bi-turbo produces 510 HP and not 493 HP.

“Sometimes you have to turn it up to 12. The SL 600 draws its strength from 12 bi-turbo cylinders. The V-12 summons 510 horsepower and 612 Ib-ft of torque.” -Mercedes Source

Power levels were bumped up a bit later in the production run.

The earlier cars, like yours, were rated for 493 hp / 590 lb-ft. "Everyone says that" because it is literally printed in the owner's manual.

In typical MB fashion, however, those numbers are likely on the conservative side.

Tunes are readily available which boost these numbers significantly; enough to make it feel like a different car. The BIG names charge ridiculous amounts for their tunes; small private businesses charge much less, have great results and can fine-tune for additional mods and desired octane.
