In this article, we find out the cost of a Mercedes Benz C250 and answer the following questions: what is the engine in the Mercedes Benz C250? What are the driver assistance systems available in C 250? Is C250 reliable? Should you buy the C 250?
How much does the C 250 cost?
The Mercedes Benz C 250 cost can be between 41,000 USD to 47,000 USD depending on the model’s specification. The C 250 model variant is only available in the fifth generation of the C Class model series 205. It was produced from 2014 to 2018 after 2018 it was replaced by the C300 model variant.
The C 250 also came with a diesel engine option and it was represented by the letter d at the end of the number. The cost of the C250 d was slightly more expensive than the petrol engine variant as diesel engines and exhaust gas after-treatment are expensive to manufacture.
The Mercedes Benz C Class model series W205/W206 is a standard sized sedan from Mercedes Benz. It is also available in the AMG line and AMG 63 model series. The C class coupe comes with a 4MATIC all-wheel-drive system. The C class comes in different body styles like 2 door sports coupe and soft-top convertible model.
C class is the entry-level model in the sedan segment of Mercedes Benz, it can easily accommodate 5 passengers and more than 400 litres of boot space. The first generation was launched in 1993 with the model series W202. It was well-received in domestic as well as international markets, the first generation of the C class was also the entry-level model in the Mercedes Benz lineup until the new generation of cars like the A-class was launched in 1997.
Currently, the C class is in its fifth generation with the model series W206 which will be replacing the W205 C class. The C class is manufactured in all Mercedes Benz factories; the only exceptions are the AMG 63 and AMG 63s models which have hand-built high-performance engines.
The C250 and 250d offered good performance and fuel economy but customers looking for more power went with the C 300 as it had better output and was also available with the 4matic drive system. Customers looking for more fuel economy usually bought the C180 or C200 model variants.
The C250 models were stuck in no man’s land and therefore Mercedes Benz pulled the plug on the C250 petrol model. The Diesel C250 d had a longer run than the petrol model as the torque of the engine was good and diesel is a cheaper fuel than petrol in most of the international market.
What is the engine used in the Mercedes Benz C 250?
The older generations of the C class used the M271 inline 4 cylinders 2.0 litres petrol engine in the C250 model variants. The C 205 continued to use inline 4 cylinders but the engine in the new generation of the C class was M274. M274 was miles ahead of the performance of M271.
The engine and cylinder head are made up of aluminium alloy. Cylinder walls are lined with Nanoslide coating. Nanoslide is an extremely thin coating applied to the inner surface of the cylinder to reduce friction between the piston. Twin-wire arc spraying (TWAS) is used to spray an extremely thin coat of iron-carbon alloy on the cylinder walls. The friction between the piston and piston rings is reduced by almost 50 per cent.
The double overhead camshafts were partially mounted in the cylinder head cover and cylinder head, this allowed for much lighter construction from M271.
Variable valve timing was achieved by camshaft adjustment for both intake and exhaust camshafts which can advance or retard the opening and closing of intake as well as exhaust valves. Thanks to the camshaft adjustment the torque curve of the engine is very wide with maximum torque generated as early as 1800 rpm.
M274 also introduced a secondary coolant circuit for the liquid-cooled charge air intercooler. The turbocharger is a wastegate type with linkage operated by a vacuum cell. The boost pressure transducer controls the vacuum supplied to the vacuum cell according to the signal from the engine control unit.
The biggest improvement over the M271 was in the Fuel system, the M274 fuel system is a direct injection and fuel injectors are directly mounted in the fuel rail. A single high-pressure fuel pump generates a fuel pressure of 200 bars; it is driven by a spring-loaded cam roller on the exhaust camshaft.
There is an independent vacuum pump driven by the intake camshaft and the intake manifold vacuum is fully utilised to improve the cylinder charging. The C250 used 7 G Tronic gearboxes and later 9G-Tronic was also introduced in limited markets with the facelift model.
What driver assistance systems are available in the C250?
The C250 did not have many advanced driver assistance systems like the latest C class with model designation C206. The following are some of the assistance systems available in the 250 as standard.
- Reversing camera.
The C250 used a reverse camera located in the trunk handle. The camera can be activated by reverse gear. There is also an option to open the camera cover from the command operating menu. Display from the camera is available in the command display with guidance lines moving according to the steering inputs.
This system monitors driver steering inputs and checks for any irregular movements. If the journey is long, attention assists alert the driver to take breaks and maintain focus while driving.
- Cruise control
Vehicle speed can be set to cruise on the highways with the help of a cruise control selector lever. The driver must be aware of the surroundings as there is no active brake assist or radar sensor.
Parktronic uses proximity sensors located on the front and rear bumpers. The driver can check the distance to the obstacle with the help of LED indicator lights on the front dashboard and the rear roof trim.
Is the Mercedes Benz C250 reliable?
The fourth generation of the C class had many reliability issues with the ABS wheel speed sensor and the camshaft adjusters. C250 in the fifth generation of C class W205 rectified the reliability issues of the previous generation. The C250 is a very reliable car and only a few engines were affected by abnormal noise concerns due to defective camshaft adjusters.
There are also a few cases reported with faulty auxiliary oil pumps on the C250 models with the 7G-Tronic transmission. The auxiliary pumps caused disruption in the CAN network of the car and replacing the pump was the only solution.
The Mercedes Benz C 250 was priced correctly and had good performance and comfort levels. But it was not a good choice considering the C 300 model was only a little bit more expensive than the C250 and offered a better drivetrain with the 4matic system.
