BTW, the diesel HPFP pump the fuel to even larger pressure than the gasoline engine. A major advantage of diesel over gasoline is that diesel act as a lubricant.
I should have clarified.

I meant that it's not the same HPFP that exists in the 335i.

Around here diesel is more expensive than 93 octane gas. If I had a 335d I don't think I'd be able to recoup the extra cost of the car/fuel for as long as I owned the vehicle.
Bet money that he was pushing the car a lot harder than belied in the article.

This is mixed city/highway. My trip to Phoenix over the holiday had me pacing for a 700+ mile tank (and I didn't go the random routes he did), until I started doing a bit of city driving while there.

That is if you are so inclined to tamper with the stock car ofcourse, and not entirely necessary.
Urea is ridiculously cheap, and as mentioned, is covered by the maintenance agreement..and it's every 15k miles. Really not a big deal. A 125lb/ft torque boost is not common out of JUST a PROcede, and requires bolt-ons as well. Add a tune to the 335d, however, and you're over 500lb/ft of torque with minimal effort (and I *am* talking about at the wheels, not at the crank, since the car already has 525lb/ft of torque at the crank, give or take). Since you've apparently not driven the 335d, your opinion is subjective about 'fun to drive'. You don't need to rev to 8k for a car to be fun. Once you've heard or ridden in the 335d under WOT, I promise you that you won't have the same opinion you do now.
