Default UK Engines: High rev test?

I was just curious about UK standards for cars. The reason cited in "Evo" for the US 2.5L Sti engine not making its way to the UK s because it would not pass a "high revving test" (p. 022 <- I knew this would come in handy oneday).

I was just wondering if someone could clue me into what this is, or if it was just 'slang' since most UK cars are free revving behemoths.

If I had a scanner, I would scan the article for those of you without the magazine.

If you read carefully, they are talking about "high revving" emissions tests. This statement has nothing to do with seeing how well the engine will rev or with durability issues - if that was what you were implying.

250bhp 'PPP' Kit For WRX

Subaru's fabulous new WRX is currently being scrutinised by Banbury-based Prodrive, which hopes to have a 250bhp upgrade available by May. The STi can already be had with a Prodrive Performance Pack but for those who can't quite stretch to it or feel that an STi is a little too uncompromising, the new WRX PPP should strike the perfect balance between outright power and everyday usability.

As with the STi's performance upgrade, Prodrive has limited changes to engine management and a freer-flowing catalyst and tailpipe. Final power outputs have yet to be confirmed but Prodrive has already extracted around 260bhp from the WRX engine. This would probably be pegged back to around 250bhp so as not to tread on the toes of the standard STi but expect similar torque of around 250lb ft. The slightly softer set-up of the WRX works brilliantly on UK roads and the WRX PPP could very well be the pick of the range. The performance kit will cost 2-2.5K, bringing the total cost to around 22-22,500.

Meanwhile, North American enthusiasts can now order the top-spec STi, but not as we know it. The US STi, launched at the Detroit Show, has a 2.5-litre version of the fabled Subaru boxer engine that kicks out an impressive 300bhp and 300lb ft torque. It's a real surprise that the US market is getting a higher spec engine as often performance variants are made a little tamer before they are deemed suitable for the Americans. The US press pack even talks of lightweight rear window glass and a stereo is only listed as an option!

Subaru UK says that there are no plans to bring the bigger-engined STi to the UK. Although US emissions regulations are very strict they don't include a high-revving test and this may mean that the bigger engine doesn't meet UK regs without extensive engineering work. Even so Prodrive said it was 'very interested' in the engine, mainly because the extra capacity will mean a much more torquey delivery.
I guess they haven't heard about the EPA's new Supplemental Federal Test Procedure (SFTP) US06, where emissions are measured during rapid acceleration to speeds OVER 80 MPH. Contrast that with Europe's "high speed" emissions test, the Extra Urban Drive Cycle (EUDC), which has a maximum speed of only 120km/h (74.5 mph). Compare the drive cycles yourself. First the US "high speed" test:

and then the EU's "high speed" test:

The US test seems designed to mimic a Honda Civic driver on crack. It's meant to simulate, using EPA terminology, aggressive driving. On the other hand, the EU's test looks pretty tame with lots of cruising thrown in.
