Pricing and specifications of the upgraded Mercedes-Benz CLS53 AMG S have been revealed ahead of the car's local showroom debut in October.
Unveiled at January's Detroit auto show, the update introduces 'S-Model' mechanical, equipment and styling enhancements to the high-performance CLS-Class 'four-door coupe' sedan and Shooting Brake wagon variants, similar to those applied to the new E63 AMG S.
Power and torque from the 5.5-litre twin-turbocharged V8 of the Mercedes CLS63 AMG S rise 44kW and 100Nm for peak outputs of 430kW at 5500rpm and 800Nm from 1750-5000rpm.
The power boost cuts the sedan’s 0-100km/h sprint by three-tenths to 4.1 seconds, while the wagon is just one-tenth off the pace at 4.2sec. Both are electronically limited to 250km/h, though an optional driver’s package unlocks a more potent 300km/h top speed.
Despite the performance increase, combined cycle fuel consumption remains at 10.0 litres per 100km for the sedan and 10.3L/100km in Shooting Brake guise.
Differentiating the CLS63 AMG S from the rest of the CLS-Class range is an AMG body kit comprising a unique bonnet, single-bar black and chrome grille, front bumper, rear diffuser and sports exhaust with quad outlets; wide-track front axle; 19-inch 10-spoke matt grey alloys; red brake calipers; and S-Model badging.
As before, the flagship CLS features a seven-speed dual-clutch automatic transmission with four drive modes and Race Start function, as well as ride control sports suspension with adjustable dampers, high-performance brake system, speed-sensitive sports steering, and a limited-slip differential.
The enhanced cabin comes standard with black nappa leather and alcantara upholstery, sports seats with AMG logos and silver seatbelts, performance steering wheel, instrument cluster with race timer, IWC analogue clock, illuminated doorsill panels, piano black trim and brushed stainless steel pedals.
Standard safety includes distronic plus adaptive cruise control, blind spot and lane keeping assist systems, Pre-safe brake and brake assist pre-emptive systems.
The Mercedes-Benz CLS63 AMG S sedan is priced from $262,645 while the Shooting Brake costs from $265,145.
