It didn't lose 3 horsepower. Horsepower means different things throughout the world.

250 German (international) Horsepower = 247 American Horsepower

It is about a 1% difference.

I read a short Q&A with the Mazda release manager linked from this forum about a week ago and he said:

247 horsepower at the crank after EPA certification
204 horsepower at the wheels

(I wish I had bookmarked the link).

Also for what it's worth, my dealer said the reason for the long port delay was the cars failing one of three EPA tests.

 

You are all right.

Mazda had said 250 HP for most of the waiting period.

Mazda changed this to 247 HP a few months back, probably after EPA certification.

The magazine ads just say "250 HP" without qualifying what "HP" means.

The big glossy brochure that opens on either side (Part No 9999-92-010R-04) says "Horsepower, SAE NET - 250."

There's also a disclaimer saying that anything may have changed after publication of the brochure and you should check with your dealer for actual information.

Bottom line, though, it's 247, and if you don't think that's good enough, buy something else...

 

I know it's not a big difference but he said 204-207 hp at the wheels. Is it common for a car to lose 40 hp in drivetrain losses? How does it work, a fixed hp loss or a percentage?

 

lol Us Euro's have lost 20bhp before it gets to the wheels 231ps or 228bhp then drivetrain loss ...

 

I've just gained over 6hp on the Atkins Diet then!:D

 

It's funny reading this thread now... LOL. It's funny Mazda was never sued over the HUGE discrepancy between their numbers this time around.

 

rofl

 

he he - the claim went from 250 to 247 to 232
The actual we now know - is more like 215 at the flywheel .
Wonder what the original poster would think of that !
