Ok, our FSE stopped by for awhile today and it turns out that at the last minute BMW has decided against the twinturbo setup for the E90
Instead they will bump up the displacment to 3.5 and 3.0 liter, which will end up rendering the x25 a thing of the past.
In 2007 the 2.0 inline 4 twinturbo diesel engine will be in the US however. Laying down 220+ HP and 416 ft-lbs torque. Coming with the diesel will be the E87 1 series, however it will only be availible as a sedan. BMW won't be bringing the hatch version over here for some reason. Also look for the 635 and 630 to be availible.
Our first E61 arrived today. A gunmetal 530xi. The wagons will be availible in 2 or 4 wheel drive for the inline 6 engines but the 550 touring will only be availible in 2 wheel drive.
I will update te designations portion of the thread a bit later to include the E61 5 series touring.
