BMW B58B30, B58B30M0, B58B3000 engines
Content
The series of BMW B58B30, B58B30M0, B58B30O0 engines is quite fresh, but many motorists have already liked it. The new line of 6-cylinder engines quickly became popular due to its wide power potential and long service life.
Historical summary
Serial production of engines began at the beginning of 2015 and blocked the production of the previous generation - the N52 models. BMW B58B30, B58B30M0, B58B30O0 series motors are manufactured for new BMW production cars, namely:
- Liftback 3 series in the back of F30 or F31;
- Station wagon 3 series with a body 335i;
- Sedan 4 series CF32 F;
- 7 Series sedan with 340i body
- And an exclusive version of the long 7 Series 740I G sedan
This is interesting! At the time of the launch of large-scale production, the B58 series was represented only by the B58B30M0 engine, the rest of the engines appeared later due to the need to fit the power unit to the framework of a particular car. The entire B58 series has similar technical characteristics, but differs in dimensions and mounting system.
Specifications: what is special about the BMW B58B30, B58B30M0, B58B30O0 models?
The main feature of the B58 series engines is a body made of aluminum and carbon fiber, which made it possible to reduce the weight of the power unit to 100 kg. Lightweight motors are easy to install in any car, regardless of body architecture, which guarantees a balanced weight distribution.
The six-cylinder B58 is characterized by high power and performance, which is explained by the manufacturability of the equipment - among the design features are:
- Indirect charge air cooling system;
- Upgraded fuel intake and exhaust system;
- Installation of a paired Vanos system;
- Stabilized crankshaft.
The BMW B58B30, B58B30M0, B58B30O0 series equipped with a mass of electrical equipment - the introduction of a programmed control system made it possible to adjust the oil pump, as well as fuel and cooling systems. This step made it possible to reduce fuel consumption and increase the performance of the power unit without reducing the operational resource: the engines are less overloaded, which prevents the possibility of overheating.
| Characteristics | Parameters |
|---|---|
| Displacement, sm3 | 2998 |
| CO2 emission in g / km | 159 – 204 |
| Maximum power, hp | 326 – 360 |
| Maximum torque, N * m (kg * m) at rpm. | 500 (51) to 4800 |
| Cylinder diameter, mm | 82 – 89.6 |
| Number of valves per cylinder | 4 |
| The piston stroke, mm | 84 – 94.6 |
| Compression ratio | 10.2 |
The B85 series functions stably only on high-octane fuel - the use of gasoline of a class less than A95 leads to detonation in the cylinders, which significantly reduces the life of the power unit. Average fuel consumption is 8.9 liters in the city and from 6.5 liters on the motorway.
Engines also need high-quality technical fluid: 5W30 or 5W40 oil is recommended to be changed every 7 km with a mandatory flushing of the system. The average fluid consumption per 000 kilometers is 1000 g.
It's important to know! The VIN number of the motors of the series is stamped on the front of the crankcase - the presence of a serial code in another part of the engine indicates that the model is not original.
Weaknesses and shortcomings of the series: an overview of design features
BMW has taken care of the reliability of the series - all engines are characterized by high-quality assembly and flexibility of software settings, which allows you to calibrate the engine for any driving style. The factory equipment of the B58, with timely maintenance and gentle use, has practically no vulnerabilities, however, with intensive use, the following can be observed:
- Cylinder chipping - an aluminum and carbon fiber body can crack when the engine is chronically overheated or as a result of attempts to artisanally increase power;
- Loss of compression - the problem is characterized by rupture of seals caused by engine overheating or constant operation at high speeds;
- Increased fuel consumption - the situation consists in the failure of electrical equipment. To correct it, it is necessary to reset the settings of the fuel supply system and turbine control to factory settings, and also, if necessary, adjust the ignition.
The B58 series has a long warranty and if there are malfunctions in the engine, it is better to seek help from an official service station.
Possibility of tuning
The BMW B58B30, B58B30M0, B58B30O0 engines operate through direct fuel injection and the operation of a blower turbine, which expands the possibilities for modernization. To increase the power potential of the power unit, it is necessary:
- Replace the exhaust system with a sports model;
- Install a high power turbine;
- Reflash the fuel injection system;
- Stabilize the ignition for increased power.
Note! Boring cylinders or replacing pistons with non-original models is strictly prohibited, as the aluminum and carbon fiber body may not withstand processing. An increase in power by more than 400 horsepower is fraught with a decrease in the operational resource and the approach of expensive repairs.
Conclusion: briefly about the possibilities of the series
In 2017, the BMW B58B30, B58B30M0, B58B30O0 series took the top spot in the "Reliable Engine of the Year" list, proving to be a stable and durable option for everyday driving. The mass of electronic equipment and build quality guarantees an operational life of components of 400 km, however, with the timely replacement of consumables and regular engine diagnostics, much more will pass.
Particular attention must be paid to the quality of fuel and engine components during the period of guaranteed maintenance: if factory defects do not surface up to 50 km, the engine will last for decades. A car based on the B000 is perfect both as a family vehicle and for businessmen or sports car enthusiasts.
