2020 Mercedes-AMG CLA 45 S 4MATIC+ Shooting Brake Technical Data:
Engine: 2.0-litre 4 in-line with roller bearing twin-scroll turbocharger
Displacement: 1991 cc
Max. output: 310 kW (421 hp) at 6750 rpm
Peak torque: 500 Nm at 5000-5250 rpm
Drive system: AMG Performance 4MATIC+ fully variable all-wheel drive with AMG TORQUE CONTROL
Transmission: AMG SPEEDSHIFT DCT 8G dual-clutch transmission
Combined fuel consumption: 8.4-8.2 l/100 km The stated figures were determined in accordance with the prescribed measuring method. These are the “NEDC CO2 figures” according to Article 2 No. 1 Implementing Regulation (EU) 2017/1153. The fuel consumption figures were calculated based on these figures.
Acceleration 0-100 km/h: 4.0 s
Top speed: 270 km/h electronically limited
One new feature which makes a substantial contribution to the incomparable driving experience is the active, fully variable AMG Performance 4MATIC+ all-wheel drive: for the first time, this system offers selective power distribution to the wheels on the rear axle via AMG TORQUE CONTROL. This means that the power is distributed to the left and right rear wheels highly flexibly and at different ratios, according to the given driving situation – resulting in optimum traction, whatever the road surface conditions and whatever course the route takes. In addition, spectacular Drift mode (standard on the S-Model, included in the optional AMG DYNAMIC PLUS package for the base model) provides for even greater driving enjoyment. This is made possible by a newly developed rear axle differential, which for the first time incorporates two multi-plate clutches. These open and close at lightning speed to control the torque flow for each rear wheel individually.
The extremely dynamic driving experience in a completely new dimension is greatly assisted by the fully variable all-wheel drive included as standard. The secret is AMG TORQUE CONTROL in the new rear axle differential: This has two electronically controlled multidisc clutches, each of which is connected to a rear axle drive shaft. In this way, the power can not only be completely variably distributed between the front and rear wheels, but also selectively between the left and right rear wheel. This means that depending on the drive mode, the traction can be separately distributed to both rear wheels.
The result is consistently optimum traction, even in adverse road conditions and during extreme cornering manoeuvres, for example on the racetrack. Furthermore, this sophisticated solution allows Drift mode (standard in the S-Models, included in the optional AMG DYNAMIC PLUS package for the basic models), which makes “powersliding” possible for even more driving pleasure. Drift mode can be called up in the “RACE” driving mode using the shift paddles, provided that ESP® is deactivated and the transmission is in manual mode.
With an output of up to 310 kW (421 hp), the completely new Mercedes-AMG 2.0-litre engine is currently the world’ s most powerful turbocharged four-cylinder manufactured for series production. Mercedes-AMG has bettered the output of the preceding engine by 30 kW(40 hp). Maximum torque has also increased from 475 to up to 500 newton metres. The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, on the “One Man, One Engine” principle.
The four-cylinder engine delivers extremely agile drive power in two output ratings: with 310 kW (421 hp) as the S-Model and with 285 kW (387 hp) in the basic version. The new compact sportscars absolve the sprint from zero to 100 km/h in record time: the CLA 45 S 4MATIC+ Shooting Brake requires just 4.0 seconds, while the base model CLA 45 4MATIC+ Shooting Brake gets up to speed in 4.1 seconds. The top speed of the base model is electronically limited to 250 km/h, while the S-Model leaves the factory with a top speed of 270 km/h. With the optional AMG Driver’s package, the base variant can also driven at up to 270 km/h.
Apart from its performance figures, the new engine impresses with its immediate response. To this end the torque curve was carefully balanced (“torque shaping”): The peak torque of 500 newton metres (480 newton metres for the basic version) is available in a range of 5000-5250 rpm (4750-5000 rpm in the basic version). With this configuration the AMG engineers have achieved a power delivery akin to a naturally aspirated engine.
With a maximum charge pressure of 2.1 bar, the 2.0-litre four-cylinder turbo engine is also the leader in its segment in this respect. The electronically controlled wastegate (exhaust relief valve) allows the charge pressure to be controlled even more precisely and flexibly while optimising responsiveness, especially when accelerating from partial load. Numerous parameters are taken into account in this process.
