BMW N62B48TU engine

The Bavarian concern BMW has top engine families, which are produced from the noughties to the present day. They have won the trust of the public, as they have impressive characteristics and are also famous for their reliability and safety. Among such families, the N62 series deserves the most attention.

This lineup is extensive, and during the period of production has acquired several powerful power units. From year to year, the series was replenished with new generations of engines, which adopted the best features of the predecessor – M62TU. This led to the appearance of the N62B48 engine, and then to the well-known modification – N62B48TU.

For starters, it’s worth noting that there are more powerful engines in the BMW lineup, with high torque and good performance even under extreme loads. But few engines have the balance of performance, reliability and economy that the N62B48TU boasts.
With a displacement of 4799 cc. it has a maximum power of 333 hp. As for torque, the gasoline engine produces 490 N*m at 3400 rpm. Fuel consumption deserves special attention. The N62B48TU motor consumes 11.1 liters of gasoline AI-95 or AI-98 (your choice) per hundred kilometers.

The given information shows that the V-shaped eight-cylinder N62B48TU has high power and performance indicators. The same has been repeatedly proved in practice. It was originally intended for the X5 xDrive48i E70 and excelled in a variety of driving conditions, accelerating this solid SUV to 100 km/h in 6.5 seconds. Here it is advisable to take into account that the X5 xDrive48i E70 has a mass of no less than 2785 kg, and the N62B48TU engine is sharp enough to make the driver feel confident on the road.

Advantages

Once again, the N62 series is extensive, but this engine has a number of characteristic innovations that distinguish it from other engines. We are talking about:

• in the intake duct;
• DISA intake system;
• a new crankshaft and dipstick;
• modified oil pump;
• refined intake and exhaust valves;
• implemented management system ME9.2.2-3;
• improved spark plugs;
• the presence of a secondary air supply system.

This is why the N62B48TU has gained its popularity. CO2 emission is 260 g/km. Of course, at this level, it is difficult to call this engine a leader in terms of environmental friendliness, but even the same Bavarians had “dirty” motors, which, nevertheless, are still in use and in great demand.

Disadvantages

Here it is necessary to mention the high oil consumption. Owners of other BMW models face a similar problem. By the way, many owners of E90 complained that the oil pressure was lost. Unfortunately, it is hardly possible to correct this shortcoming. The owner should prepare for the fact that the N62B48TU is demanding to oil and needs it constantly. In addition, this engine has one unpleasant peculiarity – lubricants get into the fuel mixture, especially during over throttle, as a result of which there is a blue smoke with a characteristic smell of oil from the exhaust pipe.

At first, this problem is not so noticeable, especially if you drive the SUV with N62B48TU in a measured and careful manner, without over throttling. However, as the operation progresses, this defect becomes more and more noticeable, and if not regularly serviced, it may entail:

• clogging of internal components;
• the destruction of catalysts;
• increased engine wear.

If catalytic converters are not deformed and replaced in time, tiny fragments enter the combustion chamber. It is not difficult to guess that this leads to damage to the cylinders and, as a consequence, expensive repairs. The solution to this malfunction can be timely replacement of oil caps. In addition, you should not leave the car idling for a long time, because the operating temperature of the engine reaches 105 degrees Celsius.
The undeniable advantage of this engine is that in Russia you can easily find all the necessary spare parts for its partial or major repairs. This is facilitated by official dealers. If their price is too high, then you can use the dismantling. Services engaged in the sale of used parts can offer parts of good quality and at a reduced price.

Chip Tuning

As noted above, the base power of the N62B48TU is 333 horsepower, but simple manipulations can increase this figure. There are cases when this engine
gave out 367 hp at 6300 rpm, which is a good indicator. This is facilitated by the adaptation of valvetronic on the launcher.

The explanation for such a power increase is that BMW engineers knowingly underestimate the factory parameters, increasing the reliability of the engine N62B48TU and reducing its wear. Besides, even 333 hp is enough for SUVs. If you need to increase this indicator for the sake of dynamics, then you should take care of filling good oil and gasoline with high octane number, because otherwise there may be a variety of malfunctions N62B48TU.

In addition, it is recommended to monitor the operating temperature of the engine so that it does not overheat. Alternatively, you can think about the cooling system so that it effectively removes
warm air and cools down the engine.

Conclusion

The N62B48TU is the perfect solution for the large and heavy X5 xDrive48i E70. With proper care of the car, you can avoid a lot of difficulties and extend the life of this engine. By the way, motorists followed this path and still use N62B48TU without serious problems. As for the increased oil consumption, it can be
regarded as a reasonable payment for good dynamic performance and reliability.
