5 Things You Might Not Know About the C6/4F RS6

1. The bumper side vents are for the intercoolers

The intercoolers received their air from these vents, and increased the density of the intake air resulting in greater efficiency and the the lower temperature also suppressed knocking. The compressed air streams were then merged, then distributed to the small individual cylinders in the intake manifold.

2. The Torsen T3 Differential can send up to a 100% of the power to the rear wheels

In normal conditions, power was usually distributed with 40% going to the front and 60% to the rear resulting in a 40:60 split, and also up to 70-80% going to the front wheels when needed. A 100% can also go to the rear axle depending on driving styles, the axles featured open differentials with electronic diff locks.

3. The engine uses no balance shafts, yet it is still well balanced

The iconic BUH engine featured IHI RHF55 turbochargers with one per cylinder bank providing a boost pressure of 23.2 psi (1.6 bar) and a compression ratio of 10.5:1. It used an aluminium engine block and was claimed to be the first even firing aluminium block V10 engine. These engines are quite popular in the tuning scene being able to hold over 800 horsepower on stock internals, without compromising on reliability.

4. It's quite different compared to the S6

The RS6 is fitted with Dynamic Ride Control, which makes the suspension tougher when cornering in order to get rid of body roll. The BUH engine also had a forged steel crank shaft that pinned its entire length, unlike the split design on the S6’s BXA engine.

5. It uses a Lamborghini derived engine block

The BUH engine has 400 other unique parts which weren’t found in the Gallardo 5.0 though, and it’s also related to other Audi V10 engines like the BUJ, BSM and so on.
