Why did Subaru do this?

They must have had a reason for it?
Any ideas, suggestions?

Mainly down to the new emission rules

But they still churn out shed loads of CO2?

But less than before.

Think it was to do with the euro 5 standard, less to do with co2 and more to do with nitrogen dioxides ect. Might be totally wrong though!

Emission regulations, the bigger the engine the more **** it's allowed to pump out. The JDM cars still use the 2.0.

only because they had to have a 2.0 base car to be able to build grpN rally cars...............

Quick question Alyn, how come the UK Mitsubishi Evo's still use a 2.0, with the stricter emissions regs?

The 2.5 pumps more CO2 out but because its bigger it gets away with it (silly I know....)

There's no ban on the 2.0 emissions level, Subaru just get penalised by taxes/fines/etc.

Maybe Mitsi are just taking that on the chin, or maybe the engine is just more efficient natively... I dont know the stats on it.

More torque, more power, less lag, better powerband, improved fuel economy and lower emissions.

It's actually a brilliant idea: the 2.5 is lovely to drive and will produce great numbers. Unfortunately it was just very poorly executed by subaru, hence all the reliability issues.
