Is the Facelifted Version of the E53 SUPERIOR? (2005 and 2006 production runs 4.8is)

[BMW-x5-48is]

Hello my fellow x5ers.. I wanted to share something I came across in my finds... I get my car serviced at a local shop that only does BMW for the past 20-30 years.. They told me I am lucky I got the last of the facelifted models as they had steel parts others dont have.. I didnt quite know what he ment so did some digging around and find this nice info below... Infact there is even a small HP difference, between a 2004 x5 4.8is, and a 2005 one or a 2006 one.. see below :-)

Engine: N62B48 4.8 L (4799 cc/292 in³)

265 kW (360 PS) @ 6200 500 N·m (369 lb·ft) @ 3500 6500 for
year: 2004

270 kW (367 PS) @ 6300 490 N·m (361 lb·ft) @ 3400 6500 for year: 2005



as you can see above - there is small difference of HP and Toque from 2004 to 2005 and 2006 models... 2005 and 2006 models have 367 PS and the prior ones, from 2004 have only 360 PS.. Small difference but there is a reason for that... As you guys know shortly after 2006 BMW discontinued production of the FACELIFED E53's because new models (E70s) were coming off the line... So believe it or not, the last of the X5's the 4.8is with the upgraded parts were ONLY avaliable for 2 years in all of bmw history (2005's and 2006's)...and the 2005 and 2006 year one seen ADDITIONAL improvements over the previous models...


N62B48 Update (They did this update only for last 2 years of production)
The N62 was updated. Originally the N62B48 engine was developed for the 2004 BMW E53 4.8is. Bore was increased to 93.0 mm (from 92.0 mm) and stroke to 88.3 mm (from 82.7 mm) for the 4799 cc N62B48 engine. So they ALMOST like STROKED the beast..... see below guys more interesting stuff:

Updates for the N62B48 engine included:

1.) The crankshaft bearing caps featured apertures to improve ventilation lengthways in the crankcase and reduce pump and splashing losses;

2.) The introduction of a steel crankshaft for greater strength;

3.) Symmetrically-formed and narrower connecting rods

4.) A stronger aluminium-silicon alloy cylinder head

5.) Revised exhaust manifolds which prevented residual gases from entering the combustion chamber to improve cylinder charge and torque progression at lower engine speeds; (great for CITY DRIVING)

6.) A modified oil pan that was made from steel (previously cast aluminium) and had a 16 mm lower bottom section; and, An increased capacity oil cooler.


WHO THE HELL KNEW !!! I though the 2004 were identical to the 2006 year ones.. I guess not??? So seems the 2005 and 2006 ones were the best of the best.. If you have that year.. consider yourself lucky I guess
