A detuned Formula 1 engine seems very unlikely considering:
1: F1 engines are limited to 3.0ltr displacement
2: Usable Rev renge is well above 10000RPM, max 18500RPM. This is not usable on street cars and especially not within the important US market where torque is important.
3: It won't be very reliable, a F1 engine only has to last 450km-500km. Developing an engine that has to last 100k++ miles will be impossible.
A V10 with at least 5.0 liters displacement will certainly one of the possibilities.
1: The new 6.0 litre V12 will provide for an excellent basis. Cut two cylinders and you get 5.0 litres!
2: Compared to a V8, a V10 allows smaller and thus lighter pistons and valves. There are a lot of benefits. The most important is that small cylinders are more efficient.
3: Compared to the V12, a V10 has smaller cranck-and camshafts. With smaller shafts, the magnitude of the torsional and harmonical vibrations are smaller. This allows a higher revving engine. Even compared to the older S38 and current S62 there may be benefits.
4: Last but not least, BMW already has gathered a lot of production experiences with a V10, the F1 engines.
