The diesel R8 is pointless though.
Why if you spent 80k on a car would you car about your fuel bill?
I mean I don't see why anyone would drive a diesel by choice for any other reason than a low fuel bill.
I dont know about you but I really like the power delivery of a good diesel engine, especially the latest 2.0 D in BMWs (350Nm torkz!). I'd take a 120d over a Focus ST anyday. (first and last time i will say it!

So a Diesel V10? BAM!!!!!
