With over ten engine variants, with two using turbochargers for added umph.

As stated, of the engines offered, two of them use turbo assemblies. One engine is a dual turbocharged diesel engine, since this post in on turbochargers, lets discuss a twin turbo arrangement. The one we are speaking of is a parallel twin turbo, not the sequential twin turbo arrangement.
Parallel twin-turbo is a description of a turbocharger system in which two identical turbochargers function in parallel at the same time, splitting the turbocharging duties equally. Each turbocharger is driven by half of the engine’s exhaust gasses. In essence it lowers the wear and tear on the turbo system, it is also a more complicated and expensive system to care for. Of course, it is made by BMW. So the supreme German engineering is there.
The turbo-ed gasoline engine offered in the E90 is called the BMW N54 engine. It is an inline 6 cylinder motor with 3.0 liters of displacement [2979cc or 181 cubic inches] having direct injection and twin turbochargers. Technically called the N54B30 it ranged from 306 horsepower to 335 horsepower depending on the year and model of Series 3 BMW.
A turbo is an outstanding and popular method of extracting more horsepower and torque from a smaller motor, thus saving weight [from a bigger engine] and offering unusually good fuel mileage for a super car like this.
