Some automaker tease us with blurry images featuring upcoming models, others release videos that give glimpses of what their new engine will sound like.
One such automaker is Bentley who has been working on their new twin-turbo 4.0-litre V8 for quite some time, so if you’ll follow the jump you will hear "the
prelude to a potent new Bentley driving experience that begins in 2012".
This upcoming engine was developed by Bentley in collaboration with Audi and even though its specifications remain unknown we could still have an idea of what to expect considering that the twin-turbo V8 in the Audi S8 delivers 520 HP and 650 Nm of torque.
