The new BMW twin-turbo V-8 has been engineered for a new line of cross-over SUVs for 2009. Technically, it's a unique peice of work: instead of the usual turbocharger location that you'd expect, the turbos are housed inside the V of the engine. The cylinders heads are reversed, with the exhaust ports inside the V and the intake ports on the outside.
- Advantage: packaging of the engine in roughly the same width and length as the standard V-8.
- Disadvantage: height, heat on the top of the engine, and management of overall airflow thru the engine compartment.
