Mercedes-AMG SLC43 replaces SLK55

Mercedes-AMG SLC43 replaces SLK55

The Mercedes-AMG SLC 43 flicks its SLK 55 badging, swaps its atmo V8 for twin-turbo V6 and is ready for a price drop.

Joining the rush towards engine downsizing with forced induction, the new six in the compact roadster delivers 270kW from 5500rpm to 6000rpm, and 520Nm from 2000rpm to 4000rpm. Teamed with a fresh nine-speed automatic, the SLC 43 claims a 4.7-second 0-100km/h.

As we’ve previously reported, the 310kW/540Nm bent-eight dies, as the SLK 55 was the last vehicle in the AMG range to utilise the atmo 5.5-litre donk. The new engine is 0.6L/100km thriftier, claiming 7.8L/100km, although SLC 43 is a tenth slower than SLK 55 to the ton; which is the biggest hint the AMG version may be repositioned.

Meanwhile, re-engineered front and rear suspension kinematics include increased negative camber on all wheels, new front wishbone guide bearings and rear forged-aluminium track rods. Along with stiffer engine and rear-axle gear unit mounts, AMG says it contributes to making the SLC 43, “more controllable when driven at the limit”.

Mercedes AMG SLC43 replaces SLK55 interiorAMG Dynamic Select is now standard, with Eco, Comfort, Sport, Sport+ and Individual modes. The latter allows a mix and match of transmission aggression, steering (weight-only, as it’s not a variable ratio system), exhaust (flaps open in the Sport modes) and where applicable chassis preferences.

Three-mode AMG Ride Control adaptive suspension is optional, as is a mechanical limited-slip differential for the rear-drive roadster. An independent button works the three-mode stability control program, with on, Sport Handling Mode and off settings.

It is highly likely the new engine will prompt a price drop on the $162,400 SLK 55 AMG when the SLC 43 arrives locally in October 2016 – whether it is small or substantial remains to be seen, but we expect the latter.
