Mercedes-Benz 117 model CLA of the manufacturer Mercedes-Benz is a four-door mid-range vehicle ( C 117 ).This was presented to the public on 15 January 2013. The manufacturer refers to the four-door sedan as a four-door coupe .Stars in the Euro-NCAP - crash test (2013) the full 5 stars.

History

As part of the Mercedes-Benz Fashion Week Berlin and launched on 13 April 2013 Europe-wide after production began on 25 January 2013. The only production site is the factory in Kecskemét, Hungary .

A first study called Concept Style Coupe was presented at the Beijing Motor Show in April 2012. The C 117 is the third model based on the modular front-drive architecture (MFA). The approximately equal size Mercedes C-Class has rear wheel instead of front-wheel drive. This also explains why, for reasons of space, only four-cylinder engines are used on the CLA.

In the first year of sale 59,200 copies were sold worldwide. Around half of the customers did not previously drive a Mercedes-Benz model .

Following the success of the CLA , Mercedes-Benz presented a station wagon variant at the end of 2014 . The Mercedes-Benz CLA Shooting Brake (X 117) recalls detail elements such as the frameless side windows on a coupé, but at the same time offers the versatility and utility of a station wagon. The market launch took place on March 28, 2015. 

On March 16, 2016, Mercedes-Benz released information on the revised version, which had its world premiere at the 2016 New York International Auto Show . It was available from April 2016. In July 2016, she came to the dealers. 

Specifications

The main features of the design and the proportions of the CLA are based on the larger and higher-positioned CLS . The concept of the four-door coupé, which was established in 2004 with the CLS in the upper class, should also be realized in the middle class.

The C 117 has a long bonnet, a narrow window graphic and frameless side windows, which are a unique feature in this class. The front shows similarities to the A-Class , but there are differences, such as the slightly modified shape of the headlights or the side air intakes in the skirt. The radiator grille with the Mercedes-Benz star integrated in the radiator grille is not visually integrated in the bonnet, but designed separately.

The roof is flattened coupé like the domed tail ends slightly sloping in. With almond-shaped tail lights. The fuel cap is typical for Mercedes-Benz - on the left side.

The design of the interior is strongly based on the A and B class . The basic version of the C 117 has a three-spoke steering wheel with aluminum double strut from the CLS . The instrument cluster has two analogous round instruments, each containing another small round instrument, between which there is a 11.4 cm multifunction display. On the instrument panel is analog as of the B-Class . The central display with a diagonal of 14.7 cm in the base and 17.8 cm with the choice of navigation system, which is located above the three air vents in the cross design of aluminum, is now integrated into the instrument panel top. Below the decorative element with the air vents there is a control unit, which flows to the armrest and consists of two separate compartments, starting with the operation of the radio and the navigation system and including the climate controllers. The control knobs are made of aluminum.

The shift lever is omitted on models with the dual-clutch gearbox , the handbrake is replaced on all models by an electric parking brake (triggers automatically when starting), so that instead of two storage compartments. The operation of the radio and navigation system takes place via a rotary and push button in front of the center armrest.

The CLA is equipped as standard with Collision Prevention Assist . It is a radar-based collision warning with adaptive brake assist . It reduces the risk of a rear-end collision from 7 km / h upwards through visual and audible warnings of detected obstacles. At the same time, the brake assistant prepares for the upcoming braking, which is initiated as soon as the driver presses the brake pedal clearly.

For the CLA , the preventive occupant protection system Pre-Safe known from the larger series is also available. The standard equipment includes the fatigue warning Attention Assist , the hold function of the brake and hill start assist . Available as an option are the adaptive cruise control Distronic Plus , Adaptive Highbeam Assist, a Blind Spot and Lane Keeping Assist, a traffic sign recognition , a parking assistant , the voice control system LINGUATRONIC and a reversing camera.

When Collision Prevention Assist and Distronic Plus are available, autonomous braking is initiated at speeds up to approximately 200 km / h when a collision threatens and the driver does not respond by reducing speed.

Engines 

At the market launch, five engines with only four cylinders are offered. On the side of the gasoline engines there is a 1.6-liter direct-injection engine with turbocharger and a power of 90 kW (122 hp). In addition to the normal version CLA 180 , this engine is also available in the aerodynamically and fuel-efficient CLA 180 BlueEFFICIENCY Edition . The 115 kW (156 hp) more powerful version of the same engine in the CLA 200 ranks above that . Furthermore, there is the CLA 250, a two-liter direct-injection engine with turbocharging, which comes to a power of 155 kW (211 hp). On the diesel engine side, only the most powerful variant of the OM 651 will be offered. The CLA 220 CDI mentioned model from 2.1 liters of displacement 125 kW (170 hp). All engines meet the Euro 6 emissions standard at the start of the market. In addition, the CLA 45 AMG with 265 kW will be available from June 2013 .

As of September 2014, the CLA 200 CDI has a capacity of 2.1 liters instead of 1.8 liters and since then has been offered with four-wheel drive as the CLA 200 CDI 4MATIC . Since then, the CLA 220 CDI has also been offered as a 4MATIC variant. The CLA 220 CDI (4MATIC) has a power output of 5 kW (7 hp) for vehicles delivered from the beginning of November 2014.

Manual transmission 

As a transmission, a newly developed 6-speed manual transmission is used for the two weaker gasoline engines. The three-shaft gearbox with the designation F-SG 310 is very compact with a length of 345 mm and has a low dry weight of 46 kg. The upper shaft, which contains the reverse gear and the gears three and four, does not run in an oil bath. As a result, the drag torque is reduced and the shifting comfort is also given in cold operation. The first two gears are synchronized via a triple cone, while the following gears have a double cone. These measures also increase the shifting comfort. A magnet on the selector shaft, passing through a Hall sensor is detected, ensures that the current gear position is detected. The start-stop system and the reversing lights, which are standard in all models, are controlled by this. Gears are laid by cables while the clutch is hydraulically operated. The shift forks are made of cast aluminum and are roller-mounted in the gearbox.

Dual Clutch Transmission

As automatic a specially comes from Daimler -developed dual clutch transmission used. The 7G-DCT transmission is fitted as standard in vehicles with the most powerful diesel and gasoline engines and is also available at a surcharge for all other engines. The exception is the CLA 180 BlueEFFICIENCY Edition , which is only available with the 6-speed manual transmission.

The 7G-DCT is a split-shaft three-shaft transmission. The partial transmissions each have their own multi-plate clutch running in the oil bath , which allows switching without interruption of traction. The spread of the gears was chosen at 7.99 high, in order to provide sufficient torque at low gears while lowering the speeds in the higher gears. The 7G-DCT is 367 mm long and weighs 86 kg. Despite an oil filling quantity of only 6 l hydraulic oil Sufficient cooling is ensured because the oil is actively cooled. In addition to a mechanically driven oil pump, there is an electric auxiliary pump, which supplies the gear during a stop operation with the engine off with oil. Thus, the restart can be done without delay, and the standard start-stop function can be easily realized. In addition, the electric auxiliary pump supports the mechanical pump at high loads. The hydraulic of the mechanical parking lock is electronically controlled, whereby the gear selector lever could be positioned right behind the steering wheel. Thus, more storage space was created in the center console.

The driver can choose three transmission programs. The Economy program switches fully automatically and is designed for economical driving. In sport mode , the transmission also shifts automatically, reducing the response times for a sporty driving style. In the third mode, the driver manually shifts the gears via shift paddles behind the steering wheel. In the automatic shift programs, the driver can also make manual shift interventions, whereby the automatic mode is reactivated after 10 seconds without further switching operations. This time is extended on downhill or on winding roads. Permanent communication between the transmission and engine control unit ensures improved efficiency. 

Suspension 

Front is MacPherson front suspension , rear a newly developed four-link - rear axle installed. In addition to improved handling, this allows the later use of the 4MATIC all - wheel drive . Initially, only variants that are powered by the front wheels offered. There is a choice of suspension options, including the optional sports suspension with direct steering, with the front body lowered by 15 mm and the rear by 10 mm. The CLA has a Dual Pinion EPS , an electromechanical steering system with an electric motor built directly into the steering box.
