2020 Mercedes-AMG A 45 S 4MATIC+ Technical Data:
Engine: 2.0-litre 4 in-line with roller bearing twinscroll 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: 8.4-8.3 l/100 km (The stated figures were determined in accordance with the prescribed measuring method) Acceleration 0-100 km/h: 3.9 s Top speed: 270 km/h electronically limited
The active, fully-variable AMG Performance 4MATIC+ all-wheel drive distributes the power to the rear axle wheel-selectively by AMG TORQUE CONTROL – for top traction and the spectacular Drift mode.
This is made possible by a new rear axle differential featuring two multidisc clutches – one for each rear wheel. With an output of up to 310 kW (421 hp), the completely newly developed 2.0-litre engine is 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. With an output per litre of up to 155 kW (211 hp), the new Mercedes-AMG high-performance turbo engine even ranks ahead of many well-known super-sports car engines.
The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, on the "One Man, One Engine" principle. In the 45 models, the four-cylinder ensures extremely agile performance in two output classes: with 310 kW (421 hp) as the S-model and with 285 kW (387 hp) in the basic version.
This positioning logic has already proved successful for the AMG Performance models with a V8 engine, and meets individual customer wishes even better. The new compact sportscars absolve the sprint from zero to 100 km/h in record time: the A 45 S 4MATIC+ requires only 3.9 seconds (CLA 45 S 4MATIC+: 4.0 seconds), while the basic A 45 4MATIC+ model absolves this discipline in 4.0 seconds (CLA 45 4 MATIC+ in 4.1 seconds).
The top speed of the basic models is electronically limited to 250 km/h, while the S-models are capable of up to 270 km/h ex factory. With the optional AMG Driver‘s Package, the top speed can also be increased to 270 km/h for the basic variants. 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 maximum torque of 500 Nm (480 Nm in the basic variants) is available within a range of 5000-5250 rpm (4750-5000 rpm in the basic variants). With this configuration the AMG engineers have achieved a power delivery akin to a naturally aspirated engine.
The engine developers were able to realise a dynamically increasing torque curve in the lower engine speed range, thereby improving throttle response. The increasing torque at higher rpm makes the engine more free-revving. Moreover, the high maximum engine speed (up to 7200 rpm) emphasises the engine's sporty character.
To reduce friction between the pistons and cylinders, the linings are coated using patented NANOSLIDE technology. This gives the linings a mirror-like surface for minimal friction, is twice as hard as conventional grey cast-iron liners and therefore makes them much more durable. NANOSLIDE was developed by Daimler AG, and is protected by more than 90 patent families and more than 40 patents. This coating was first used in AMG's M 156 V8 engine, has enhanced other AMG engines for many years and can also be found in the Formula 1 engine of Mercedes AMG Petronas Motorsport.
Turbocharging and direct injection with a spray guided combustion process not only allow a high power yield, but also improve thermodynamic efficiency and therefore reduce both fuel consumption and exhaust emissions. For the first time, the new high-performance four-cylinder has two-stage fuel injection. In the first stage the particularly fast and precisely operating piezo injectors supply fuel to the combustion chambers at a pressure of up to 200 bar. This is a multiple process at times, and is controlled by the engine management system as required. In the second stage there is additional intake manifold injection using solenoid valves. This is needed to achieve the engine''s high specific output. The electronically controlled fuel supply has an operating pressure of 6.7 bar.
The 2020 Mercedes-AMG CLA45 Has 382 HP and a Rear-Drive Drift Mode
The all-new CLA45 packs the world's most powerful series-production four-cylinder.
The 2020 Mercedes-AMG CLA45 has a 382-hp turbocharged engine and an all-wheel-drive system with a Drift mode.
AMG says it will hit 60 mph in 4.0 seconds, 0.6 second quicker than its claim for the 302-hp CLA35.
The CLA45 goes on sale in the U.S. late this year; so far, there are no plans to bring the 416-hp CLA45 S across the pond.
Mercedes-AMG recently showed off its newest engine, a turbocharged 2.0-liter inline-four that is the world's most powerful series-production four-cylinder. Now, AMG has revealed the first car that the new engine will be going into: The second-generation CLA45, a compact "four-door coupe" that packs a whole lot of power: 382 horsepower, to be exact, 7 hp more than the outgoing model.
But before we get into the details, a caveat. The car in these photos is a Euro-spec CLA45 S, which packs 416 horsepower and a number of other features not found on the "base" CLA45; so far, Mercedes says it has no plans to bring the S model to the United States, but we're keeping our fingers crossed.
The CLA45's 382-hp turbo four—more details on it here—is mated to a 4Matic+ all-wheel-drive system and a new eight-speed dual-clutch automatic transmission that delivers superfast shifts and strong acceleration no matter the gear. With its standard launch-control function, Mercedes says the CLA45 will hit 60 mph in 4.0 seconds, a tenth quicker than its claim for the 2019 model—which went from zero to 60 in 3.8 seconds in our testing.
Top speed is quoted at 155 mph. An AMG exhaust system is standard and has a flap that automatically opens or closes depending on the driving mode for better noise. The new, variable 4Matic system packs what Mercedes calls AMG Torque Control on the rear axle differential. Essentially, there's an electronically controlled multi-disc clutch connected to a driveshaft for each rear wheel, which allows torque to be distributed between both the front and rear wheels and each rear wheel individually. That means the CLA45 can send 100 percent of its 354 lb-ft of torque to just the rear wheels, making it essentially rear-wheel drive, and when equipped with the available Drift mode, the CLA45 will be able to easily do just that: drift.
Mercedes doesn't detail exactly what the mode does to achieve the "spectacular" powerslides it says the CLA45 can do, but it requires stability control to be deactivated and the car to be in manual mode. Also part of the 45's range of enhancements are up to six different configurable driving modes, the AMG Dynamics stability-control system that debuted on the updated C63, model-specific steering tuning, and additional chassis bracing.
The CLA45 has different suspension tuning and a number of new components, and three-mode adaptive dampers are optional. Up front are 13.8-inch brake discs with four-piston calipers, while the rears are 13.0-inch discs with single-piston calipers.
An available Dynamic Plus package adds the adaptive dampers, an increased top speed of 167 mph, touch control buttons on the steering wheel, bigger brakes with red calipers, and the aforementioned Race and Drift modes. Compared to its lesser CLA250 and AMG CLA35 brethren, the 45 is visually distinguished by AMG's vertically slatted Panamericana grille and large lower air intakes in the front bumper. The front fenders are wider, there are new side skirts, and a bigger rear diffuser houses quad round exhaust pipes.
Multiple 19-inch wheel designs are available, and the CLA45 can be had with exterior styling packages that add more gloss-black trim pieces, more chrome trim pieces, or additional aerodynamic enhancements like front dive planes and a rear spoiler that increases downforce. On the inside, there are new sport seats, an AMG steering wheel, gloss-black trim, stainless-steel pedals, a ton of special displays and functions for the MBUX infotainment system, and a whole bunch of AMG badges. Standard upholstery is a combination of black MB-Tex and microsuede, with a number of red accents covering bits including the seatbelts, the air vents, and the stitching.
Leather upholstery in multiple two-tone color schemes will be available, along with AMG Performance bucket seats. Mercedes hasn't announced pricing for the CLA45, but when it goes on sale in the U.S. by the end of the year it should be a bit more expensive than the current model's $54,095 base price. If the CLA45 S makes its way across the pond, it could arrive a few months later with a sticker price about $10,000 higher.

Los cuatro cilindros salvajes de AMG: 421 CV de locura
¿Sacar 421 CV de un motor de 2.0 litros y cuatro cilindros salvajes? ¿Cómo lo hacen? Intentar explicar al ceo de AMG, Tobias Moers, que la potencia máxima de un motor es solo un número… El hombre no puede contener el orgullo de que el nuevo propulsor M139 de 421 CV AMG, que monta el A45s, sea el motor turbo de cuatro cilindros más potente en producción. Pero todavía hay más, los rivales no están ni cerca. El del BMW M135i rinde 306 CV. El del Civic Type R, 320 CV. De acuerdo, son coches en otra línea de precios, pero lo cierto es que con las mismas herramientas básicas: cuatro cilindros, 2.0 litros de desplazamiento y un turbo –el motor AMG es un 30% más potente– o 50 CV más por litro. Entonces, ¿cómo lo ha hecho AMG? La clave de la eficiencia y la potencia en el M139 es la orientación. Descrito por Moers como una unidad “fundamentalmente nueva”, el bloque está girado 180 grados comparado con el predecesor, así que el colector de escape y el turbo se asientan detrás del motor, y el sistema de admisión va delante. ¿Las ventajas? Menos “tubería” y entrada más directa y eficiente para el escape y admisión, junto a un capó más bajo para una menor resistencia.
Pero la potencia no es nada sin control, y AMG ha trabajado duro en evitar que el M139 y 4 cilindros salvajes se convierta en un motor como una granada de mano, con retardo e insensible. La turbina del turbo de doble caracola está alimentada por dos conductos independientes del colector, de modo que la corriente de presión del turbocompresor es más constante en todo el orden de encendido de la mecánica, aumentando su par y la capacidad para responder a las órdenes de su pie derecho. Con ese fin, el turbo gira sobre rodamientos más caros y de baja fricción, un detalle heredado de los V8 de AMG.
La potencia y la durabilidad aumentan aún más con un sistema de enfriamiento que trabaja a destajo –el turbo está refrigerado por aire, agua y aceite–, un cárter de diseño superrígido inspirado en la competición y pistones de aluminio forjado que funcionan en cámaras recubiertas con un recubrimiento de baja fricción desarrollado en la F1. Y, por supuesto, al igual que sus V8, cada M139 es ensamblado con todo su amor por un solo técnico de AMG, de manera que esos 4 cilindros salvajes hayan sido construidos con el máximo mimo.
Solo lo mejor
El gran turbo de doble desplazamiento se trata como a la realeza, con conductos gemelos del colector de escape para aumentar el par y la respuesta. También tiene un sistema de enfriamiento robusto, gira sobre rodamientos de rodillos y es manejado por una válvula de descarga electrónica, para optimizar el turbo para cualquier combinación de posición del acelerador.
Listo en todo
La atención al detalle está en todas partes. La bomba de agua es eléctrica, no está vinculada a la velocidad del cigüeñal, por lo que funciona tan fuerte como sea necesario. Y cada válvula de escape tiene la opción de dos levas, en lugar de una comprometida.
Girado por completo
En relación con su predecesor, el motor M139 de AMG gira 180°; turbo y escape en la parte trasera del compartimento del motor, admisión en la parte delantera. Las tuberías más cortas y directas ayudan a aumentar la eficiencia.

En Practicas
Buenas tardes.
A mi el Clase A me gusta muchísimo y tiene que ser una "bomba" en todos los sentidos.
Me gustaría saber las rev. del turbo cuando sopla para el par máximo y la cantidad de calor que hay que disipar para refrigerarlo con tres sistemas, como para que el S&S te lo pare en "seco". No se donde estarán los límites de la física en los motores de calle, pero "haberlos haylos".
Un saludo.
