The six-cylinder engine is reserved for the SLC 43 from Mercedes-AMG: the 3.0-litre V6 biturbo engine is characterised by a high power output together with low consumption and emissions. Installed close to the engine, the two turbochargers are especially spontaneous in their response. The high power output of 270 kW (367 hp) is attributable to, among other things, the 1.1 bar charge-air pressure. Especially tough and, therefore, wear-resistant, the NANOSLIDE coating on the cylinder liners reduces friction, thereby contributing to higher efficiency. The same applies to the spray-guided multiple injection with up to 200 bar fuel pressure. The AMG powerplant can be identified by the red aluminium insert in the engine cover.

The 9G-TRONIC sports transmission is specially matched to the demands of the SLC 43. By specifically adapting the software, the AMG developers have been able to significantly shorten the shift times. The multiple downshift allows even faster short bursts of speed, while the double-declutching function in the "Sport" and "Sport +" transmission modes makes for an even more emotive driving experience. In "Sport +" mode, partial ignition interruptions provide even faster gearshifts.

The standard-fit shift paddles allow lightning-fast manual shifting of the automatic transmission without the driver needing to take their hands off the steering wheel. Shifting in "Manual" mode, which is activated using a separate button next to the selector lever, is twice as fast as in the other transmission modes. Also, the transmission stays in the selected gear and does not automatically shift up when the engine speed reaches the limit.

With the standard sports suspension or the optional AMG Ride Control sports suspension with adjustable damping, the Mercedes-AMG SLC 43 offers two suspension options designed for high lateral acceleration and reduced roll. Common to both suspensions are the specially developed front and rear axles, which guarantee precise wheel location and high camber stability on compression and rebound.

The three-link front axle has been provided with stiffer steering knuckles, improved elastokinematics and increased negative camber. In combination with the likewise newly developed wishbone guide bearings, this design results in significantly more agile cornering, more precise and direct suspension feedback from the road and fast cornering speeds.

The four-link rear axle with optimised elastokinematics, increased negative camber and special forged-aluminium track rods not only improves the driving dynamics, but also makes the SLC 43 more controllable when driven at the limit.

The special AMG mountings for engine and rear-axle gear unit offer the ideal compromise between handling and comfort. They also contribute to the snappy and highly stable driving impression given by the roadster.

With its automatic adjustable damping system, the optional AMG Ride Control sports suspension allows an even more personalised suspension set-up, with each wheel being individually electronically controlled. The three suspension settings "Comfort", "Sport" and "Sport +" can be selected by the driver via the transmission modes using the DYNAMIC SELECT button.

The mechanically controlled AMG limited-slip differential on the rear axle makes for improved traction and handling in all driving situations, particularly when the driver adopts a sporty driving style. This is achieved by reducing the slip on the inside driven wheel when cornering, without control intervention in the brakes. When there is a difference in rotational speed between the rear wheels, the torque is distributed to the wheel with the better grip in order to reduce wheel spin.

The benefits are:
  • better acceleration out of bends
  • better acceleration from rest
  • greater stability on braking and at high speed
The AMG high-performance braking system is characterised by excellent deceleration, high fade resistance and precise brake control. Large-sized, internally ventilated and perforated brake discs are capable of absorbing plenty of braking energy and quickly dissipating the arising heat. Lightweight aluminium brake calipers reduce the unsprung mass, resulting in improved handling and comfort.

With the five DYNAMIC SELECT transmission modes Eco, Comfort, Sport, Sport + and Individual, the driver can change the characteristics of the SLC 43 at the tap of a finger. The available range extends from efficient and comfortable to extremely sporty. This modifies key parameters, such as the response of engine, transmission, suspension and steering. The modes are selected using a button in the centre console control panel.
  • "Eco" transmission mode: all parameters are programmed for maximum efficiency. The ECO start/stop and coasting functions (overrun mode for fuel-saving vehicle operation) are activated.
  • "Comfort" transmission mode: comfortable and fuel-efficient driving, e.g. thanks to early upshifts. Suspension and steering are set up for an emphasis on comfort.
  • "Sport" transmission mode: sporty characteristics thanks to a more agile response to accelerator commands, shorter shift times, earlier downshifts and more emotive gearshifts owing to double-declutching. A more dynamic set-up of suspension and steering.
  • "Sport +" transmission mode: extremely sporty characteristics thanks to an even more agile throttle response, increased acoustic emphasis on double-declutching on downshifts as well as selective torque control on upshifts with cylinder suppression for optimal shift times. Increased idle speed for faster pull-away. An even more dynamic set-up of suspension, steering and drivetrain.
  • "Individual" transmission mode: personalised set-up of drive, suspension, steering, air conditioning and ECO start/stop function.
Independently of the DYNAMIC SELECT transmission modes, the driver has the option of pressing the "M" button to switch directly to manual mode, in which gearshifts are executed exclusively using the shift paddles on the steering wheel.

Further personalisation of the driving dynamics is possible by means of the ESP button, which offers a choice between three control strategies for the Electronic Stability Program:
  • ESP "ON": early system intervention without adversely affecting the sporty character
  • ESP "Sport HANDLING MODE": late system intervention for a sporty driving style
  • ESP "OFF": system deactivated for an extremely sporty driving style on closed racing circuits
