Hi,

I am not an Audi owner, but I am considering buying a second-hand A4 or A6 with the Multitronic transmission. The reason for this is just because I like the concept of a CVT, but they've never seemed to be any good until Audi took the bull by the horns!

My question is this: would a diesel engine or a petrol engine be more suited to the Multitronic transmission?

My first thoughts were that a petrol engine would be more suitable because, for a given power output, the engine will be generating less torque. Less torque means less slippage between the chain and the cones.

Then I thought that maybe this isn't necessarily true. Maybe more torque causes the chain to bite more and provide more friction with with to deliver the power more efficiently.

Audi must know the answer to this question, but they don't provide any contact for technical enquiries.

Maybe the difference in efficiency is small, so that the deciding factor becomes another practical consideration like noise, engine response or fuel economy.

Any ideas?

Many thanks!
