The 535d isn't listed on their Web page for the Stig lap times.
Its moderately fast for car that after all has twin turbchargers car, I would have expected more straightline perfomance.
What lap time did it get?
The quote from the top gear page was actually that they preferred the petrol engined version..?
Is the BMW 535 diesel as good as their petrol engine 5 series? Well, we wouldn't have thought so, after all, diesel engines are loud, cover the ones you love with a thick layer of soot and produce one huge lump of torque at about 3000rpm.
That said though, the 535d is really very good indeed. The secret to its success is the use of twin turbochargers. The concept isn't a wholly new one, and it's also not especially complicated either. Most people who have driven a car with a turbo, especially a diesel, will be able to tell you it's great when it kicks in. But therein lies the problem, a big turbo needs quite a lot of petrol and air going through it to make it work. So what BMW have done is stick a smaller turbo on as well. This means that you get more power throughout the whole rev range.
So, is the diesel better? Well, it's cheaper, does more miles per gallon, and at 70mph it's even quieter than the petrol version. So, in some ways yes. But let's face it, the diesel can't be better than the petrol unless it's faster. And it isn't. So it's not.

BHP is BHP, assuming the normal decent powerpand attributed to Maserati engines I can't see it even being remotely close - not remotely
