Being able to read in more than one language allows you to read even more road tests. Only reading English can give one a skewed perspective; What the Americans say about cars is best ignored, the Australian and South African markets are somewhat insular and irrelevant. The British, while masters of the language, only appear to care about diesels.
And so I was reading a Swedish comparative road test: The (then - early 2010) new Volvo S60 2.0T vs its competition from the usual German triplets. I was actually reading this test (does one need a reason, really?) for more into the featured ethanol burning A4 2.0 TFSI Quattro when I glanced across to the figures for the BMW 325i, a car I had hitherto ignored - because obviously no one can afford to run a normally aspirated 3.0 straight 6 in this day and age of downsizing and forced induction - when I was socked to see it was the most economical car in the test, beating it’s 1.8 and 2.0 blown 4pot competition. Surely not? But no, the testers were quite sure, despite being the fastest and most powerful car on test it used the least fuel. (and put out the least CO2, if you care about or even believe in that sort of thing - I assure you, your taxman does.) For the kind of practical and sensible reasons that could only be understood by a Swede the Audi was still pronounced the winner, but that’s hardly the point here. The point is that here is a “big six” you could afford to commute in, and what’s more, how did I not know about this?
Now having something to set my obsessive mind to, much very enjoyable research followed. The late 2007 facelift of the BMW e90 included, in addition to the “Efficient Dynamics” set of modifications, the new direct injection N53 in place of the the Valvetronic N52 but only in Europe. In the case of the 325i the engine was now a 3.0 instead of a 2.5. Power remained the same, torque increased slightly but the headline is the dramatically improved economy. Comparing tests done on the pre- and post-facelift 325is done by the same Swedish mag, a dramatic improvement indeed. Suddenly there is no need to bother with a Golf GTi or Skoda Octavia RS.
This knowledge of course, in addition to requiring visits to the nearest BMW dealer to check their “Premium Used” section, and replacing excitement at the launch of the new forced induction only f30 with a slightly bittersweet feeling, also lead me to suddenly wonder about a e60 5-series. Didnt it also receive the N53 and Efficient Dynamics kit - yes, in Europe it did. Doesn't that mean it will also be amazingly economical? Should I not in fact perform my daily commute in a 530i auto? No, apparently not, in the single tests each I can find of the post 2007 525i and 530i is was pretty thirsty. Sad. How can it use so much more fuel than the (only) 220kg lighter e90?
I don’t know and I am unlikely to find out due to the paucity of information I am forced to work with. Why does nobody test these cars? When someone tests a 3-series, why it is always 320d? (or a 335i?) Why wasn't more fuss made of the N53 and its amazingly economy? Why where we being told to buy 2.0 turbo 4s, when we could have had one of the last attainable normally aspirated sixes? Why it is so hard to find any test on any BMW with name ending in -25i? Yes I know I am very boring, I want to sit and read fuel consumption figures, I want to compare the e90 and e60s and work out some kind of pattern - because I live in the real world were petrol costs money and what to see what the real costs are.
I am sick of this massive diesel preference, specifically in the English motoring press. Comparing the tested figures of the last, now sadly gone e90 325i to the 320d of the same time show that you’d really have to do a lot of mileage for total cost of ownership (ignoring depreciation) of the 325i to be greater than that of the 320d. Now don't get me wrong, the 320d is a great car. I dont like diesels but I am forced to admit that it is excellent…but compared to the incredible joys of a 3.0 BMW straight6? For similar money, can you get your head around that?
And yet nobody knows, for these cars are simply ignored.
Edit 16 months later:
It appears, sadly, that the N53 suffered a fair amount of reliability issues, specifically injector problems and now appears to be largely dead. Even in the F10 its place has been taken by the new turbo 4 bangers. I say appear because, as always, there is virtually no information on this, and in any case relatively few N53 engined E90s were sold. (Because you were all to busy buying diesels, weren't you?)
But to end this on a more positive note, here is the article in the original gansta: (Excuse the language.) http://www.gizoogle.net/xfer.php?link=http://gtdriver.tumblr.com/post/17656547265/more-power-for-the-people-a-3-0-six-for-everyone&sa=U&ei=umqwUc3hJO-N7AaEsoCYBw&ved=0CCoQFjAG&usg=AFQjCNHn6JuJURy5DG6q5kre93rr_l2oMg
