Mercedes-AMG SLC 43

Performance roadster from AffalterbachMercedes-AMG SLC 43, R 172, 2015

There need be no contradiction between high driving dynamics and low fuel consumption. This is proved by the new Mercedes-AMG SLC 43: thanks to the combination of 3.0-litre V6 biturbo engine and 9G-TRONIC sports transmission, the 270 kW (367 hp) roadster consumes just 7.8 litres of fuel per 100 kilometres (NEDC, combined). Consequently, the open-top two-seater not only uses 0.6 l/100 km less than its predecessor, the SLK 55 with V8 naturally aspirated engine, but is also the most efficient six-cylinder performance roadster on the market. The specially developed suspension and model-specific mountings for engine and rear-axle gear unit are designed for high lateral acceleration and low roll. Even greater driving dynamics is optionally available with the AMG RIDE CONTROL suspension with adaptive adjustable damping and the Handling package with mechanical limited-slip differential on the rear axle.

Compact, powerful and economical: “The new Mercedes-AMG SLC 43 unites the classic virtues of a roadster with exemplary efficiency. Weighing less and with lower fuel consumption, the new SLC 43 delivers a similar performance to the SLK 55 on the race track. This vehicle provides typical AMG driving pleasure in a compact open-top two-seater in line with the needs of today’s market,” says Mercedes-AMG chairman Tobias Moers.Mercedes-AMG SLC 43, R 172, 2015

With its maximum power of 270 kW (367 hp) and peak torque of 520 Nm (384 lb-ft), the 3.0-litre V6 biturbo engine can deliver impressive performance: sprinting from rest to 100 km/h (62 mph) in 4.7 seconds, its top speed is electronically limited at 250 km/h (155 mph). The key factors behind the snappy, agile roadster driving experience are the newly developed front and rear axles, new engine/rear-axle gear unit mountings, stiff elastokinematics and highly precise steering. Even greater transverse dynamics are made possible by the optional Handling package with mechanical limited-slip differential on the rear axle.

New model, new nomenclatureMercedes-AMG SLC 43, R 172, 2016

The new SLC 43 represents the entry point into the current roadster world of AMG. As well as being renamed from SLK to SLC, the open two-seater will feature the new AMG nomenclature. The established AMG convention of a two-digit number underscores the SLC’s clear affiliation to the AMG portfolio. In combination with its overall “engineered in Affalterbach” package of typical AMG driving dynamics, engine response and high efficiency, the SLC 43 is thus very competitively positioned in the segment. The 43 here stands for the 3.0-litre V6 biturbo engine that has been further developed by the AMG engineers. The Mercedes-AMG SLC 43 is therefore the first V6 model from Affalterbach to feature the new nomenclature. This will gradually be introduced across the future AMG model range.Mercedes-AMG SLC 43, R 172, 2016

High on power, low on consumption: the 3.0-litre V6 biturbo engine

Mercedes-AMG SLC 43, R 172, 2015

Mercedes-AMG SLC 43, six cylinder engine, 270 kW (367 hp).

The new SLC models from Mercedes-Benz come exclusively with a four-cylinder powerplant. 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 (2900 psi) fuel pressure. The AMG powerplant can be identified by the red aluminium insert in the engine cover.

Short shift times: the 9G-TRONIC sports transmission

Mercedes-AMG SLC 43, R 172, 2016The 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.

Mercedes-AMG SLC 43: 9G-Tronic automatic transmission

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.

Two options: the sports suspension

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.

Mercedes-AMG SLC 43: AMG sports suspension

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.Mercedes-AMG SLC 43, R 172, 2015

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.Mercedes-AMG SLC 43, R 172, 2015

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.Mercedes-AMG SLC 43, R 172, 2016

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.
