Hi, I am about to order a new 9-5 wagon :D :D
I was just wondering what the difference is between the Linear and Arc engines (besides the Hp).
Is the turbo, intercooler, pistons etc.. different or is it just software?

Does it matter on what kind of transmission? I am ordering manual.

Thanks for replies!

Arc has an Aero engine with "detuned" software. Obviously, it can be brought back to the Aero level and beyond ;). It also has bigger brakes and some other goodies not available on the Linear.
