How many miles will a Mercedes Benz C 300 last?
A Mercedes Benz C 300 will last for more than 250,000 miles or 10 years. Mercedes Benz has significantly improved the overall built quality of the C 300. It does not have the problems commonly found in the predecessor models like the W 204, and W205 C300. The latest C300 is a fifth-generation model and it is based on the MRA-II platform designed by Mercedes Benz.
The service life of the C 300 also depends on periodic maintenance and the way it is driven. If periodic maintenance is not performed then naturally the engine and the transmission can be damaged due to degrading fluids and engine oils.
Mercedes Benz launched the fifth generation C class with the model series W 206. All the engine options in the latest C class are inline 4 cylinders with the use of a 48V high voltage electrical system. The MRA-II platform provides more rigidity and also allows the use of rear axle steering to reduce the turning radius and high-speed stability.
In terms of quality and refinement, the W206 C 300 is on par with the latest generation of the S class, and the interior design is heavily inspired by the S class. There is a rear-wheel drive as well as a 4Matic model in the C 300.
Why is the Mercedes Benz C 300 so reliable?
The Mercedes Benz C 300 is so reliable because of the following reasons:
New engine and transmission
The Mercedes Benz C 300 has the latest engine and transmission combination. The engine is an inline 4-cylinder M254, it has an all-aluminum engine block and cylinder head construction. There are double overhead camshafts partially mounted between the cylinder head and the cylinder head cover.
The cylinder walls have an anti-friction Nanoslide coating along with a conical honing which helps to reduce wear and improve the fuel economy. The turbocharger has a specially designed exhaust manifold, exhaust gasses from cylinders are accumulated before it is directed to the turbine wheel in order to increase the efficiency and the boost pressure of the turbocharger.
The fuel injectors have piezo crystals, the control unit can precisely control the fuel injection quantity. There is also a multi-spark mode in the ignition system that can quickly produce a secondary voltage in spark plugs to produce multiple sparks in one ignition store.
Both the fuel and the ignition system are employed in all the petrol Mercedes Benz engines and it is tried and tested for reliability. The transmission is the 9-speed fully automatic torque converter used with a lock-up clutch to minimize losses.
The mechanical oil pump now works with an inbuilt auxiliary oil pump located on the electrohydraulic valve body. Both the pumps work together to produce the pressure inside the transmission, the oil filter is also integrated into the transmission oil pan.
The C 300 has an integrated starter and alternator, it is an electric motor sandwiched between the engine and the transmission. The electrical motor can not only start the internal combustion engine but also provide an additional 21 BHP to the power output of the engine.
When the internal combustion engine is running, the electric motor can generate high voltage. It charges a 48 V high voltage electrical battery in the car, a 12 V battery is also present to power the electrical systems in the interior. A DC to DC converter is used to charge the 12 V battery from the 48-volt high voltage battery.
There is no need for a conventional starter motor and alternator to start the car and generate the power supply needed to charge the battery. Hence, all the problems associated with the starter motor and alternator are non-existent.
The high voltage battery is also liquid cooled and the main 12 V battery is located in the trunk of the car. Therefore, both batteries can easily last for more than 3 years. The batteries do not require any maintenance and the battery management control unit ensures that there is no conspicuous charge balance in the battery.
All the ancillary components like the coolant water pump, air-conditioning compressor, and supercharger are powered by the ISG or integrated starter generator. There is no need for a poly V belt on the M254 engine. It is a truly beltless engine that increases the overall reliability of the vehicle.
Advanced communication network
The W 206 C class uses Flexray communication protocol, the data transfer speeds are more than 20 Mbps. A high-speed can network is also present in vehicles and a central gateway control unit is integrated to transfer data between the Flexray and CAN communication protocol.
The advanced communication networks have allowed the use of advanced driver assistance systems. Active Distronic plus, Active brake assist, and Active blind spot assist comes as standard in the Mercedes C 300. The onboard communication network is very fast and reliable.
Mercedes ME connect also allows remote access to various systems in the vehicle, Customers can not only use the pre-entry climate control without stating the internal combustion engine but also check the status of various systems in the car.
What are the technical specifications of the Mercedes Benz C 300?
The technical specifications of the Mercedes Benz C300 are given in the table below
|Technical specifications||of Mercedes Benz C 300|
|Engine||Inline 4 cylinder M254|
|Transmission||9G-Tronic fully automatic transmission|
|Maximum power||254 HP|
|Maximum torque||400 Nm|
|Trunk capacity||455 L|
|Curb weight||1575 Kg|
The fuel consumption of the Mercedes Benz C 300 in the city is 25 MPG while on the highway it’s 49 MPG. It is not possible to drive the C300 only on battery power as it has a mild hybrid system. The top speed of the C 300 is 155 Mph and the 0-62 times are 6.0 seconds.
This blog explained the reasons behind the reliability of the latest Mercedes Benz C 300. There are no rust issues in the MRA-II platform and all the suspension components along with the hybrid subframe are made up of aluminum. The C 300 is definitely built to last long and Mercedes Benz also offers 5 years standard warranty along with options for an extended warranty package that will ensure the reliability of the vehicle.
