I think that the tide is turning in favour of diesel for performance because you can get 1500-4500rpm thrust of a large NATASP petrol engine without the punishing fuel usage. But let's not forget the TFSi motors from VAG, for example. 170bhp from a 1.4 litre petrol is sensational. OK, the torque is adrift of a diesel with similar BHP output but the TFSi can be revved sweetly to the 6500+rpm red line and deliver performance all the way through.

Therefore, the gears can be shorter, which will increase the torque at the road wheels.

You can no longer choose diesel for just for economy, neither can you choose petrol just for performance. Neither excels at either over it's similarly priced couterpart anymore.

The gap is closing fast. Perhaps it's time for a totally new engine technology? That MB diesotto principle is interesting.

As and when I can justify buying another car (business is so slow at the moment that we're managing with one car in the family) I will probably go for a pre 2002 large engined petrol car on account of road tax and the fact that no-one wants anything over 3 litres anymore. That opens up a whole range of BMWs; Jags and Mercs or which there are thousands available up and down the UK for bargain money.

£6000 budget buys a very tidy BMW 535i V8 with a full dealer history.

No motoring is cheap, the govt has seen to that across the board.
