<< Prev Page 2 of 3 Next >>  The lithium-ion energy storage system is also a special Mercedes-AMG development. Its technology has already proven itself in the Mercedes-AMG Petronas F1 Team's Formula 1 hybrid racing cars under the toughest conditions and can also be found in the battery of the Mercedes-AMG GT 63 S E PERFORMANCE. The AMG High Performance Battery combines high power that can be called up frequently in succession with low weight to increase overall performance. Added to this are the fast energy draw and the high power density. This means that during a brisk drive in hilly terrain, for example, drivers can immediately call on the full power potential on uphill stretches, while recuperation is strong when driving downhill.The arrangement of the battery cells and the cell cooling mirror the Mercedes-AMG Formula 1 racing car. For everyday use, however, their number is many times greater in the Mercedes-AMG ONE. The capacity of 8.4 kWh is sufficient for a purely electric range of 18.1 kilometres. Charging is via alternating current and the integrated 3.7 kW on-board charger. In addition, the battery can be supplied with fresh energy via recuperation or from the combustion engine. The lithium-ion, high-voltage battery and the DC/DC converter supporting and charging the 12 V onboard electrical system are accommodated in space-saving configuration in the vehicle floor behind the front axle. The basis for the high performance of the battery is the innovative direct cooling: A high-tech coolant flows around all the cells and cools them individually. Background: Every battery needs a defined temperature for optimum power delivery. If the battery becomes too cold or too hot, it noticeably loses power at times, or has to be regulated to avoid damage if the heat becomes excessive. The even temperature of the battery therefore has a decisive influence on its performance, service life and safety. The coolant circulates from top to bottom through the entire battery past each cell with the help of a high-performance electric pump and also flows through a heat exchanger attached directly to the battery. The system is designed to ensure even heat distribution in the battery. The result is that the battery is always in a consistent, optimal operating temperature window of 45 degrees Celsius on average - no matter how often it is charged or discharged. It may well be that the average temperature is exceeded when driving at high speeds. The protection mechanisms are therefore configured so that the maximum performance can be obtained from the battery, with the temperature level subsequently lowered by direct cooling. Only direct cooling makes it possible to use cells with very high power density. Thanks to this individual solution, the battery system is particularly light and compact. The low weight is also due to the material-saving busbar concept, and the lightweight yet strong crash structure of the aluminium housing. It ensures the highest level of safety. Another feature is the high voltage of the drive system, which operates at 800 volts instead of the usual 400 volts. Thanks to the higher voltage levels it is possible to significantly reducing the cable diameters, for example, thereby saving design space and weight. All in all, the High Performance Plug-in Hybrid Drive System offers numerous intelligent operating strategies that are optimally adapted to different application scenarios. The drive programs range from purely electric operation to a highly dynamic mode (Strat 2), which corresponds to a setting used in Formula 1 qualifying for the best possible lap times. Despite the high system complexity, the driver will always receive the optimal combination of performance and efficiency - depending on the current requirement. The Mercedes-AMG ONE starts silently at first by switching on the electric motors on the front axle. In parallel, the catalytic converters are preheated. The combustion engine will not start until the correct catalytic converter temperature is reached.
Power is transmitted to the rear wheels by means of a 7-speed manual transmission completely newly developed for the Mercedes-AMG ONE. The lightweight transmission design saves weight, while integration into the body-in-white enhances rigidity and takes up little space. It is specifically designed for the high torque and speed capacity of the powerful Formula 1 hybrid powertrain. Shift rods and the 4-disc carbon-fibre clutch are hydraulically controlled. The gear ratios are designed to minimise the power difference after upshifting and keep the combustion engine at high revs. The locking differential is integrated into the transmission. The basis for the outstanding driving characteristics of the Mercedes-AMG ONE is the lightweight and high-strength carbon-fibre monocoque, the technology of which also originates from Formula 1. The same applies to integration of the engine and transmission: both fulfil load-bearing functions and completely support the rear suspension. The chassis is an aluminium construction at the front and rear, each with five links and two adjustable suspension struts. The coil-over suspension has several special features: both push-rod spring struts have been installed across the direction of travel. The innovative arrangement of the spring and damper unit replaces the function and use of a conventional tubular cross stabiliser. This solution reliably prevents rolling movements, even during very rapid directional changes, without being uncomfortable. Roll stiffness and roll damping are completely independent of lift stiffness and lift damping. Wheel bearings with ceramic ball bearings for less friction reflect the attention to technical detail. The adaptive damping adjustment can be adapted via the drive program: the C (Comfort) and S (Sport) suspension settings are available in the EV, Race Safe, Race and Individual drive programs; the S (Sport) and S+ (Sport+) suspension settings are available in the Race Plus and Strat 2 drive programs. As part of the active aerodynamics, the chassis can be lowered hydraulically: by 37 millimetres on the front axle and by 30 millimetres on the rear axle. In addition, a lifter for the front axle (can only be activated in the road drive programs) prevents the Mercedes-AMG ONE from touching down on underground parking ramps, for example. The overall tuning of springs and dampers has been designed for perfectly balanced, easily controllable and highly dynamic handling. This is also assisted by the all-wheel drive and torque vectoring. Unlike in Formula 1, ABS is on board as standard, while ESP® can be regulated in three stages, as is customary at Mercedes-AMG. ESP® ON stands for high safety and is always activated in "Highway" mode. ESP® SPORT HANDLING MODE allows higher yaw angles before system intervention for sporty driving. ESP® OFF switches the system off for extremely dynamic driving on closed-off circuits. All three settings are possible in "Track" mode. A new development is the 10-spoke forged aluminium wheel with centre lock, which is exclusive to the Mercedes-AMG ONE. This has a radial carbon-fibre partial cover with an aerodynamically sophisticated shape: it improves the aerodynamic efficiency of the vehicle by enhancing the flow around the wheel. This is another example of how the AMG development team has paid the utmost attention to even the smallest aspects, so as to improve the efficiency of the hypercar. Newly developed 9-spoke magnesium forged wheels designed exclusively for the Mercedes-AMG ONE are also available as an option. In addition to the centre-lock technology, they feature a patented bionic design to maximise lightweight construction and rigidity. The aerodynamically designed carbon-fibre partial cover is a good example of the combination of low weight, optimised brake cooling and aerodynamic efficiency. At the same time, nine air vanes per wheel ensure active ventilation of the wheel arch and thus improved heat dissipation from the brakes. At the front, the Mercedes-AMG ONE runs on 10.0 J x 19 wheels with 285/35 ZR 19 Michelin Pilot Sport Cup 2R M01 tyres, which were developed exclusively for the hypercar, and at the rear on 12.0 J x 20 wheels, with Michelin Pilot Sport Cup 2R M01 tyres in size 335/30 ZR 20. The exclusivity of the tyres is reflected in the design of the sidewall, which incorporates the vehicle silhouette and the number 1. A special, weight-optimised AMG carbon-fibre ceramic high-performance composite brake system is used for deceleration. The front axle sports 6-piston fixed callipers and also internally ventilated and perforated brake discs measuring 398 x 38 millimetres. The rear axle is fitted with 4-piston fixed callipers. In addition, it has internally ventilated and perforated brake discs measuring 380 x 34 millimetres. The low weight of the system reduces the unsprung masses and thus increases driving dynamics and agility. Furthermore, the ceramic brake features a longer service life, higher corrosion resistance and higher thermal stability. The "AMG Carbon Ceramic" lettering and the specially painted brake callipers visually distinguish this unique brake system. The design of the carbon-fibre body is inspired by the top class of motorsport. But above all, it embodies the Mercedes-AMG principle that fascination is always linked with function. Each component fulfils a task. The mid-engine concept based on a carbon-fibre monocoque plus a load-bearing engine/transmission unit provides the extremely muscular proportions: the cockpit is positioned far forward, as is typical for racing, combined with voluminous wheel arches, a wasp waist and a wide tail. Designers and aerodynamics experts worked closely together on the design. Even the basic body has been aerodynamically designed for maximum downforce and balance. And this move has been a successful one: the Mercedes-AMG ONE generates downforce from as low as 50 km/h, which becomes increasingly stronger as the speed increases. The front view is characterised by the large front apron, the various air intakes of which extend across the entire vehicle width. The trapezoidal centre section bears a large, white AMG logo. Above it, on the vehicle body, is the Mercedes star. It is designed in the form of an artistically and technically perfect airbrush motif - by a specialist in the UK. The AMG-typical A-wing under the centre section adds another characteristic highlight and merges seamlessly into the wings. Large air intakes dominate on the left and right, framed by U-shaped air deflectors and each divided by two black transverse fins. Flat LED headlamps blend seamlessly into the body contours. The black air outlets in the bonnet guide the hot airflow around the sides of the driver compartment. This allows the flow of fresh air to pass unhindered across the driver compartment and into the intake tract on the roof. The active flaps on the front diffuser influence the aerodynamic performance at the front axle and ensure excellent aerodynamic balance. The active air vents (so-called louvres) in the front wheel arches also increase the downforce on the front axle. The low, dynamic greenhouse has an unmistakable, spherical architecture with a distinctive window pattern. The large, dark area stands for important technical functions. These technical components form a visual contrast to the clean overall lines of the vehicle. The roof is dominated by the air intake derived from Formula 1, through which the engine draws in fresh air as needed. The black intake transitions elegantly into the black, vertical shark fin: it prevents cross-flow and/or a breakaway of airflow at the rear and thus improves cornering stability. Overall, this also means more performance and safety at high speeds. The power unit is hidden under two removable carbon-fibre covers. Large NACA air intakes are integrated into each of these, guaranteeing optimum guidance of the airflow for the radiators placed below. The side view shows a sensual and clear surface design, equally combined with functional features. The vehicle flanks are tautly recessed, with black carbon-fibre surfaces redirecting the airflow around the vehicle body as in motorsport. The airbrush design on the flanks was created by the same artist who designed the paintwork for the Formula 1 racing cars. Tight-fitting wheel arches stretch over all four wheels like muscles, ready to leap into action. The doors open diagonally forwards and upwards. The fuel filler flap is at the rear right, and the charging socket for the plug-in hybrid battery is at the rear left. The sharp spoiler lip and the two-part rear diffuser bring aerodynamic efficiency and performance advantages at high speeds. This also applies to the specially shaped underbody with longitudinal fins and openings for cooling ducts. The rear wing is a two-piece retractable blade plus integrated adjustable flap. The design of the exhaust tailpipe with its large, round outlet and two further small, round apertures has been adopted directly from the Formula 1 cars. The muscular appearance is further enhanced by the rear apron with its large, black mesh and carbon-fibre components. The tail lights each feature three diamond-shaped lighting elements to echo the graphic design of the AMG brand logo, and therefore also the design of the headlamps. The high-tech materials and colour combinations of the outer skin are transferred directly from racing. Functional exterior components are presented in exposed carbon fibre and contrasted with sculpturally sensual paint surfaces. The active, hydraulically controlled aerodynamics increase downforce on the front and rear axles and also improve aerodynamic efficiency. Depending on the driver's preference and the selected drive program, three different aerodynamic setups are available:
