The unique way the twin turbochargers work makes these performance figures possible. A smaller turbocharger yields near immediate response for swift initial acceleration before a larger turbocharger comes in midrange to provide additional thrust through to the red line. Form just 1750 rpm peak torques available to deliver a seamless wave of smooth acceleration.
The introduction of Efficient Dynamics which is a technology with Brake Energy Regeneration and the implementation of various needsonly operations of ancillary units for the first time in the 6 Series range make the performance possible.
