2014 Mercedes-Benz CLA45 AMG - Review and Release Date

Mercedes-AMG kicked off the automotive spring of 2013 in the "Big Apple" in dynamic style as the CLA45 AMG celebrated its world premiere at the 2013 New York International Auto Show. The philosophy behind this four-door mid-series coupé matches that of the successful CLS 63 AMG, the trendsetter among four-door high-performance coupés. A glance at this high-tech package suffices to show that the CLA45 AMG also has all the typical DNA to make it a perfect representative of the AMG's Driving Performance brand claim: with a peak output of 265 kW (360 hp) and maximum torque of 450 Newton metres, its turbocharged engine is not only the most powerful four-cylinder unit in series production anywhere in the world but also a highly efficient one that meets the EU6 emissions standard. With fuel consumption of 6.9 litres per 100 km according to NEDC combined figures, the CLA45 AMG meets even the most exacting requirements. The performance-oriented AMG 4MATIC all-wheel drive of the CLA45 AMG similarly sets a new benchmark in its competitive segment.

Ola Källenius, Chairman of Mercedes-AMG GmbH: "With the CLA45 AMG, Mercedes-AMG is launching a unique and highly desirable automobile with all the typical DNA of AMG. A high-tech package that includes the most powerful series-production four-cylinder engine in the world as well as performance-oriented AMG 4MATIC all-wheel drive, it embodies Driving Performance at its best."

The new four-door high-performance coupé offers an exceptional combination of an excitingly sporty driving experience, extravagant design and exclusive individuality. With the CLA45 AMG Mercedes-AMG is establishing a completely new segment - as it did previously with the CLS 63 AMG Shooting Brake (2012) and the CLS 55 AMG (2004). At the time of their launch, neither of these AMG models had any direct rivals, but went on to inspire other automotive manufacturers. Turbocharged engine, all-wheel drive and the AMG SPEEDSHIFT DCT 7-speed sports transmission - the CLA45 AMG features the same drive system that is already powering the A45 AMG to deliver highly dynamic and efficient performance.

The combination of high performance and torque, together with the performance-oriented AMG 4MATIC all-wheel-drive system, gives the CLA45 AMG driving characteristics almost on a par with those of a sports car. The performance coupé accelerates from zero to 100 km/h in 4.6 seconds and its top speed is 250 km/h (electronically limited). But the AMG 2.0-litre turbo engine is impressive not only in terms of its dynamic performance but also with regard to its efficiency and environmental compatibility. The CLA45 AMG achieves a fuel consumption level of 6.9 litres per 100 kilometres according to NEDC combined figures, while it already meets the EU6 emissions standard that only comes into effect in 2015 as well as the limit for the particle count per kilometre of 6 × 1011 part./km that will become mandatory in 2017.

The basis for these impressive figures is provided by the high-tech package which has been put together by Mercedes-AMG. As a high-performance engine belonging to the BlueDIRECT family, the four-cylinder turbo engine features spray-guided direct petrol injection via piezo injectors positioned centrally in the four combustion chambers. The combination of multiple fuel injection and multiple spark ignition improves fuel utilisation and increases thermodynamic efficiency substantially, leading to lower exhaust emissions. Other highlights include the gravity-die sandcast all-aluminium crankcase, weight-optimised crank assembly with forged steel crankshaft and forged pistons with friction-optimised piston rings, NANOSLIDE cylinder wall technology, air-water charge air cooling, generator management and ECO start/stop function.

The CLA45 AMG comes with variable, performance-oriented AMG 4MATIC all‑wheel drive as standard. In developing this all-wheel drive, the focus was firmly on performance and dynamism. The power flux to the rear powertrain is provided by a compact power take-off unit (PTU) which is fully integrated in the 7-speed sports transmission. It does not possess an oil circuit of its own. Instead, it is supplied with lubricant from the oil circuit of the sports transmission. This configuration gives rise to substantial weight advantages in comparison to rival systems which branch off power by means of an add-on component with its own oil circuit. Together with the friction-minimised tapered roller bearings, the PTU achieves an excellent level of efficiency. As an additional bonus, the system weight of the new AMG 4MATIC all-wheel drive is up to 25 percent lighter than the all-wheel-drive versions offered by the competition.

A two-part propeller shaft transfers the power from the AMG 2.0-litre four-cylinder turbo engine to the rear axle. In the interests of favourable weight distribution, an electrohydraulically controlled multiple-disc clutch is integrated with the rear axle differential. The multiple-disc clutch immediately detects slip at the front axle. A hydraulic pump instantaneously presses the discs together and channels the engine torque to the rear wheels as necessary. All this takes place virtually without the driver noticing. To enable particularly fast response, the pump is always active and does not require to be started up each time it is needed, as is customary with other systems. Power distribution is fully variable: in normal driving, the CLA45 AMG uses front-wheel drive in the interests of optimum efficiency. When the driving dynamics so require, the variable AMG 4MATIC all-wheel drive splits the torque between front and rear axle up to a ratio of 50:50 percent. The variables influencing the power distribution ratio are vehicle speed, lateral and longitudinal acceleration, steering angle, speed difference between the individual wheels, selected gear and accelerator position.

The sales release date for the CLA45 AMG is in July 2013; market launch will start in September. Sales price in Germany, incl. 19 percent VAT, is 56.078,75 EUR.
