AFFALTERBACH (Germany): Mercedes-AMG is finally ready to show off the production version of the 1,000hp+ Mercedes-AMG ONE
The world premiere today of the two-seater super sports car brings the world's most modern and efficient Formula 1 hybrid drive technology from the race track to the road for the first time - nearly 6 years after the company said it would build such a car.
It has previously been reported that only 275 units will be produced at US$2 million (RM8.8mil) apiece. All have been snapped up already.
The 1,695kg hypercar has an electric range of 18km. With all systems in play, it can sprint from 0-100kph in 2.9s, and 0-200kph in 7s, thanks to an AMG 4Matic + all-wheel-drive system and new seven-speed automated manual transmission designed specifically for it. Top speed is rated at 352kph.
Let's dig into the juicy bits.
The performance hybrid produces a total output of 782 kW/1,063 hp from one combustion engine and four electric motors.
The complex development was carried out in close cooperation with the Formula 1 experts at Mercedes-AMG High Performance Powertrains in Brixworth. The Mercedes-AMG ONE will also officially be seen in action for the first time in the UK, as part of the Festival of Speed at Goodwood from June 23-26.
Further motorsport technology found in the unique hypercar includes a carbon-fibre monocoque and carbon-fibre body to the load-bearing engine/transmission unit, active aerodynamics and the push-rod suspension.
With its complex technology, the two-seater Mercedes-AMG ONE offers even more than a Formula 1 racing car in some cases. It features the AMG Performance 4MATIC+ fully variable all-wheel drive with hybrid-driven rear axle and electrically driven front axle with torque vectoring. It can also drive purely electrically.
The E PERFORMANCE hybrid drive of the Mercedes-AMG ONE comes directly from Formula 1 . It consists of a highly integrated and intelligently networked unit comprising one hybrid, turbocharged combustion engine with a total of four electric motors.
One has been integrated into the turbocharger, another has been installed directly on the combustion engine with a link to the crankcase and the two remaining motors drive the front wheels.
The 1.6-litre V6 hybrid petrol engine with electrically assisted single-turbocharging corresponds in its technology to the current Formula 1 power unit. The four overhead camshafts are driven by spur gears.
To achieve high engine speeds, the mechanical valve springs have been replaced by pneumatic valve springs. The engine, mounted in mid-engine position in front of the rear axle, revs up to 11,000 rpm. However, for longer durability and the use of commercial super plus petrol, it deliberately stays below the F1 rev limit.
The high-revving power unit is boosted by a high-tech turbocharger. The exhaust gas turbine and compressor turbine are positioned at a distance from each other and connected by a shaft.
This allows a lower installation position for the turbocharger. On the shaft is an approx. 90 kW electric motor. Electronically controlled, this drives the turbocharger shaft directly, accelerating the compressor wheel up to 100,000 rpm before the exhaust gas flow takes over. The Formula 1 designation for this unit is MGU-H (Motor Generator Unit Heat).
The major advantage: the response improves significantly, immediately from idle speed (when the exhaust flow is still weak) across the entire rev range.
The 1.6-litre V6 engine responds even more spontaneously to accelerator pedal commands, while the overall driving experience is highly dynamic. In addition, the electrification of the exhaust gas turbocharger enables higher torque at low engine speeds. This also increases agility and optimises acceleration. Even when the driver takes their foot off the accelerator or brakes, the technology is able to maintain boost pressure at all times. This ensures a continuously direct response.
The electric exhaust gas turbocharger in the Mercedes-AMG ONE has yet another advantage: it uses part of the surplus energy from the exhaust gas flow to generate electrical energy as a generator. This is either stored in the high-voltage lithium-ion battery or fed to the electric front axle or the electric motor (MGU-K = Motor Generator Unit Kinetic) on the combustion engine.
The MGU-K has an output of 120 kW, is positioned directly on the combustion engine and is connected to the crankshaft via a spur gear system - another technology that ensures maximum efficiency and performance in Formula 1.
The two 120 kW electric motors on the front axle reach rotor speeds of up to 50,000 rpm. They are each connected to the front wheels via a reduction gear.
The front axle, which is thus driven purely electrically, operates wheel-selectively in each case and thus enables individual torque distribution for particularly high driving dynamics ("torque vectoring"). In addition, the two electric motors also allow the braking energy to be optimally used for recuperation - up to 80 percent under everyday driving conditions.
This energy is stored in the battery and is available for a longer electric range or for more drive performance. Each electric motor is controlled by its own power electronics located in close proximity to the electric motors in the floor assembly.
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 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 km.
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.
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.
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 reduce the cable diameters, for example, thereby saving design space and weight.
The six drive programs available 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.
> Race Safe: standard program with on-demand hybrid driving mode and all-electric start-up. Only when higher power is required does the combustion engine switch on.
> Race: hybrid driving mode with special charging strategy. The combustion engine runs continuously and can charge the high-voltage battery more so that full electric power is always available.
> EV: all-electric driving.
> Race Plus (race track only): active aerodynamics, chassis lowering by 37 mm (front)/30 mm (rear), firmer chassis tuning, special performance management.
> Strat 2 (race track only): active aerodynamics, even firmer suspension tuning and vehicle lowering by 37 mm (front)/30 mm (rear). Full power from all motors as in Formula 1 qualifying.
> Individual: settings according to personal preferences for the road modes.
The 0-200kph sprint in 7.0 seconds is achieved with the RACE START function in the Race, Race Plus and Strat 2 drive programs.
Completely new, automated 7-speed manual transmission
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 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.
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.
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.
At the same time, nine air vanes per wheel ensure active ventilation of the wheel arch and 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.
The design of the carbon-fibre body is based on the principle of form following 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 50kph, 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 roof is dominated by the air intake derived from Formula 1, through which the engine draws in fresh air as needed.
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 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 two high-resolution, free-standing 10-inch displays with individual Mercedes-AMG ONE graphics are finished with high-quality real-metal parts and adapted to the instrument panel.
The instrument cluster display is in a slightly raised position in front of the driver. The multimedia monitor on the right of the centre console is tilted towards the driver. The double-nozzle ventilation unit is suspended under the centre screen like a gondola. Screen and nozzles merge into one unit and underline the purist design concept. The ventilation nozzles repeat the basic rectangular shape of the displays.
The door panels are in functional, high-grade carbon fibre, and integrate smoothly into the sporty interior.
In the radically designed race steering wheel, operating and functional elements are combined with original race car components to ensure safe operation in extreme driving situations.
The "shift light" is displayed at the top of the steering wheel rim, as is usual in racing cars.
The steering wheel, which is flattened at the top and bottom and has an integrated airbag, offers further motorsport trim elements: the two integrated AMG steering wheel buttons can be used to activate various functions without having to take your hands off the wheel. For example, the drive programs, the nine-stage AMG Traction Control, or the activation of the suspension settings.
The Mercedes-AMG developers have also thought about suitability for everyday use and further ease of operation: air conditioning and electric windows are on board as standard, and the infotainment system ensures seamless connectivity.
The most important information is displayed on the road in the line of vision above the steering wheel, so that the driver is not distracted. To ensure optimal rearward visibility despite the vertical wing on the rear, the interior mirror is replaced by a screen. It shows real-time footage from a MirrorCam integrated into the rear. The screen housing is fully integrated into the roof and accommodates further controls.
Inspired by the Formula 1 racing car, the material contrasts continued in the interior. Here, too, the exposed carbon fibre of the monocoque forms a delightful contrast with the material/colour combination of the seat pans in magma grey nappa leather and black DINAMICA microfibre. With their special design, the seat inlays support air circulation at the driver's back. Yellow contrasting topstitching adds further highlights as standard, but other colours are also available.
Material-appropriate and high-quality details, such as the ventilation nozzles in silver shadow and dark chrome, create further individual highlights. The seat belt straps and contrasting topstitching in the typical AMG yellow underscore the performance claim. Customers also have extensive options for very personal individualisation, which can be specified in consultation with Mercedes-AMG.
