German horsepower battle

Audi is working on an upgrade for its 5-cylinder, 2.5-liter gasoline engine to catch up with AMG's 4-cylinder, 2.0-liter turbo in the upcoming Mercedes-Benz A45 AMG.

Audi's quattro division is impressed by AMG's engine and they plan on tweaking the combustion process of the five-cylinder unit as an attempt to squeeze additional horsepower and torque, while at the same time slashing emissions.

While the AMG 4-cylinder turbo engine produces 350 hp (261 kW), the most powerful version of the 5-cylinder, 2.5-liter TFSI offered by Audi develops only an additional 10 hp (7.4 kW) compared to the German four-pot.

Audi also has another thing to worry. In September 2014 the EU6 emissions regulations will be introduced in Europe. In an interview given by quattro development boss Stephan Reil to Motoring.com.au, he said "the five-cylinder engine has to be EU6-compliant and we have to modify it" by making changes to the catalysts and geometry.

It should be noted that Euro6 compliance is more or less almost identical to the EPA Tier 2 Bin 5/CARB ULEV-II compliance for tailpipe emissions. This could mean we could see this engine on a higher-end Audi model for the US market in a few years.

the 2.0l four pot in the S3 already has 225kw so they can do better for the 2.5l

I always thought the Porsche/Audi 3.0L I4 16V vario cam engine as last built in the 1995 Porsche 968 was worth another look. Like the 968 or not: that engine was the hammer, be it the 16V version or the 8V turbo. The 3.0ltr in a 4cylinder, the torque simply fantastic. That engine "cleaned up", to EU6 spec. with direct injection and all the modern electronics would be good for at least 350 to 420 hp. "Hubraum ist durch nichts zu ersetzen". Audi dug out the 5cyl. from the grave. Why not this I4?
