In my quest to decide which Scooby to get I came across this (pinched from the nasioc forums!)

the new 2.5l WRX and sti brochure....

Interesting reading, the recommended minimum octaine (US figures) is 91 RON, and the WRX is producing 230bhp and 235ib-ft of torque. So even on 95RON with the same state of tune this should produce 240bhp.

Same with the STi 300bhp as standard with 97ron it must be upto 320bhp.

Or am I talking through my ar$e.

US Fuel ratings are different from UK, their 91/93 Ron fuel is similar to our super unleaded.

The Litchmeister is right. It's a common mistake (even in this month's Car magazine). The US uses (RON+MON)/2, we use RON.

Roughly:
US Regular, 87 = UK 91
US Premium, 90 = UK Unleaded 95
US Super Plus, 93 = UK Super Unleaded 98

Expect the 300bhp 2.5 STI to be around 275bhp when it gets here. Not entirely sure why, maybe stricter emissions.

I guess the advent of the 2.5 will make 2.0 jap imports less desirable. I wish Subaru UK would make an formal announcement, I have money burning a hole in my pocket and still no-one seems to know when the 06 STi will appear exactly.
