<< Prev Page 2 of 3 Next >>  As a high-performance engine belonging to the BlueDIRECT family, the AMG 2.0-litre four-cylinder turbo engine features spray-guided direct petrol injection via piezo injectors positioned centrally in the four combustion chambers with an injection pressure of 200 bar. The combination of multiple fuel injection and multiple spark ignition improves fuel economy and significantly increases thermodynamic efficiency, leading to low exhaust emissions. The CLA 45 AMGShooting Brake therefore already complies with the Euro 6 emissions standard, including the limit for maximum particulate emissions that comes into force from 2016. In June of this year,the four-cylinder turbocharged engine achieved a memorable double at the "Engine of the Year Awards 2014" by winning the "New engine 2014" and "1.8-litre to 2-litre" categories. As far as its technology is concerned, the AMG 2.0-litre turbo unit is related to the 4.0-litre V8 biturbo engine in the new Mercedes-AMG GT that delivers up to 375 kW (510 hp).A twin-scroll turbocharger, maximum dethrottling of the exhaust system and an innovative new injection strategy result in an instantaneous build-up of charge pressure and swift generation of high torque from low revs. A positive side-effect: fuel consumption and exhaust emissions also benefit from twin-scroll technology. With a maximum charge pressure of 1.8 bar, the AMG 2.0-litre four-cylinder turbo engine leads the field on this front, too. The sports exhaust system with automatic exhaust flap control succeeds in resolving the conflicting aims of a dynamic driving experience and the long-distance comfort for which Mercedes is renowned: unobtrusive when driving at a constant speed, the engine's soundtrack switches to AMG's hallmark emotion-stirring tone in response to sharp acceleration and use of the double-declutching function. The AMG SPEEDSHIFT DCT 7-speed sports transmission features, three distinct transmission modes, a double-declutching function dependent on the transmission mode and a RACE START function for optimum acceleration.The strengths of the dual-clutch transmission include spontaneous gear shifts without loss of tractive power, a tailor-made control strategy based on the AMG SPEEDSHIFT functions, extremely smooth gear shifts, and a high level of efficiency. The shift times in the manual mode "M" and the sport mode "S" are extremely sporty. Quick and precise retardation of the ignition interruptions and suppressing injection under full load lead to even faster gear shifts in "M" and "S" modes, with a more thrilling sound. The transmission control fully utilises the benefits of the direct injection technology right up to the physical limits: the quicker engine response ensures that injection is suppressed with even more precision. This results in a highly fascinating shift speed and an emotional sound experience. In "C" mode (Controlled Efficiency), smooth transmission and engine characteristics support a fuel-efficient and comfort-oriented driving style. In addition, in "C" mode the ECO start/stop function is active. Another special feature designed to enhance dynamic performance and driving enjoyment is the so-called "Momentary M mode" - as seen in the new Mercedes-AMG GT sports car. AMG Performance 4MATIC - this highly sophisticated variant of the 4MATIC all-wheel-drive system provides the best possible mix of dynamism, traction and efficiency in any driving situation. This is made possible by fully variable distribution of drive torque, ranging from full front-wheel drive to a 50:50 split. 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 control 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 without the driver noticing. Power distribution is fully variable: during normal driving, the CLA 45 AMG Shooting Brake uses front-wheel drive for optimal efficiency. Depending on driving conditions and driver input, the variable all-wheel-drive system splits the torque between the front and rear wheels up to a ratio of 50:50. The 3-stage ESP program offers a choice of three customised driving modes: "ESP ON", "Sport Handling Mode" and "ESP OFF" can be activated at the push of a button. Like the other AMG high-performance compact cars, the CLA 45 AMG Shooting Brake also comes equipped with elaborate axle technology. The AMG axles feature independent steering knuckles at the front together with specially configured elastokinematics. All axle bearings have a more rigid design compared to the standard production version. These measures result in more spontaneous and direct turn-in and handling characteristics as well as greater lateral acceleration capabilities. The AMG chassis with its specially tuned spring/damper elements and more powerfully proportioned anti-roll bars forms the basis for superb lateral dynamics and reduces body roll when cornering at speed. The AMG Sport speed-sensitive steering gives the driver extremely precise control over the vehicle. The purpose-designed high-performance braking system, meanwhile, with vented and cross-drilled brake discs all round provides for dependable, instantaneous deceleration. << Prev Page 2 of 3 Next >> |
