The published power for the 4.4 Litre M62 was 286 BHP (sometimes quoted as 282 BHP) which is the same figure as quoted for the 4 Litre M60. Although the Nikasil process had been used previously with no problems, the combination of the M60 and fuels with high Sulphur levels softened the cylinder walls. Again, BMW changed the differential from 3.15 to 2.93 when the M62 was introduced (except for the Sport 740i which retained the 3.15) and the acceleration The same differential ratio change was present on the 8-Series 840ci. On the basis of M62B44 a junior 3.5-liter variation was produced, named M62B35, and a model with displacement 4.6 L M62B46 and M-version – S62B50. Mechanically the M62 lost a couple of useful parts, the duplex timing chains and the idler sprocket, in their place was added a single timing chain and plastic chain guides.
As Nikasil deterioration resulted in catastrophic engine problems due to bore failure there were no engines that were affected but kept running for any length of time, and this meant that the Nikasil failure period was limited. The resultant wear meant a loss of compression and as the engine was designed without replaceable cylinder liners the engine was Although a great many M60's were re-fitted with a new short-block by BMW, these were initially Nikasil blocks and could have failed again. It was sold alongside the M30 straight-six and the mighty M70 5-Litre V12 in the E32. The long final drive ratio certainly didn't help, especially since the part-throttle gear-changes were made well below the power-band.

BMW N62B48 N62 4.8L Turbo Engine BMW N62 From Wikipedia, the free encyclopedia The BMW N62 is a V8 DOHC piston engine which replaced the M62 and was produced from 2002–present.
Again, BMW changed the differential from 3.15 to 2.93 when the M62 was introduced (except for the Sport 740i which retained the 3.15) and the acceleration figures again remained the same.The same differential ratio change was present on the 8-Series 840ci. The long final drive ratio certainly didn't help, especially since the part-throttle gear-changes were made well below the power-band. The M60B30 was fitted to my first 7 Series and was a good introduction to this great engine, I'm on my 7th BMW Mention the M60 engine, even today in 2018, and the next word will be Nikasil. A successor to the BMW M60, the M62 features an aluminium engine block and a single row timing chain.
The BMW M62 is a naturally aspirated V8 petrol engine which was produced from 1995 to 2005. In performance terms, the M62 produced a hefty amount of torque at lower revs and the more sophisticated DME 5.2 engine management increased fuel economy.However, the improvements didn't really make that much difference, especially with the longer final drive, and it wasn't until the M62TUB was introduced that the performance targets were realised. The M62 engine is a consistent further development of the BMW V-8 cylinder engine series introduced in 1992. The M62 was produced as the 3.5 Litre M62B35 and the 4.4 Litre M62B44 and fitted to the E31 and E38. BMW's solution was to replace the Nikasil process with a new cylinder-hardening process called Alusil. BMW M62 firing order – 1-5-4-8-6-3-7-2. Perversely, the published acceleration remained the same as did the BHP, owners who have driven both versions would disagree. To address the lack of performance at low revs the M62 was introduced in 1995.The M62B44 fitted to the 840ci, the long cable across the front of the engine is for cruise The M62TUB44 fitted to the E38 - The CC, ASC and throttle cables have been replaced with EMLThe M62 was produced as the 3.5 Litre M62B35 and the 4.4 Litre M62B44 and fitted to the E31 and E38. The DME 5.2 engine management added a lot tighter control of the engine and the diagnostic capabilities were increased drastically.The M62TUB44 is really the engine that the M60 aspired to be, it has heaps of low-down torque, is economical and produces much lower emissions. In 1998, a "Technical Update" was applied to the M62, resulting in the M62TU variants. The new V8 produced more power per litre, but more importantly it was more economical and produced less pollution. In 1998, a Technical Update included VANOS (variable valve timing) for the intake camshafts. After a shaky start the modern BMW V8's have proved to be an unrivalled success. After a shaky start the modern BMW V8's have proved to be an unrivalled success. Around the same period, the Sulphur levels in fuels was reduced and those engines that suffered bore wear were replaced, and those that were not replaced were not affected once the Sulphur levels decreased. The new V8 produced more power per litre, but more importantly it was more economical and produced less pollution. Welcome to RealOEM.com! Perversely, the published acceleration remained the same as did the BHP, owners who have driven both versions would disagree. In the United States, power for 2001-2003 540i models was increased to 216 kW (294 PS; 290 bhp).The M62TUB46 is based on the M62TUB44. It was sold alongside the M30 straight-six and the mighty M70 5-Litre V12 in the E32. It has been many years now since Nikasil failure was a worry with the M60 engine - It might have been expected that the 730i V8 (218 BHP) would have much better performance than the 730i I-6 (185 BHP), and the M30 engined E32 would be dropped - but this was not the case as BMW fitted the V8 models with a 3.23 differential whereas the I-6 730i got the much shorter 4.1. Engines produced from 1996-on are considered to have two banks (bank-1 and bank-2). The M62B46 was developed by Alpina, and was designated the F3, based on the M62B44. Alusil technology integrates silicon throughout the aluminum cast so that liners or treated bores within this block family are not needed.
