Hotness...now it finally can compete with the Audi RS-4.

Damn thats sexy

Updated with more engine details. BER:thumbup:

Awesome! Why do the headers glow red-hot during testing? I don't imagine that happens when driving the car, does it?

You mean destroy the RS4. :thumbup:

Just wait for the FI setup on the RS4... :)

I still wish BMW would put some real torque numbers down for these HP numbers. 420hp/420tq...that would be a motor :drool:

:wow:

The way BMW is making the current M engines, allows them to be more responsive. Geared correctly, the lower torque doesn't matter at all.
