2018款奔驰S级轿跑车和敞篷车近日亮相法兰克福车展，这两款车与年初发布的轿车版采用相同改款幅度，但增加了OLED尾灯组。作为标配，双门版S级的尾部采用左右各33组OLED光源。这也是车尾最大变化。而S63和S65的车头采用Panamericana格栅.其中S63搭载了一台4.0升而非原来的5.5升V8双涡轮增压引擎，虽然排量下降，但功率提升了20千瓦/27马力至450千瓦/612马力，扭矩900牛米。除了动力升级，S63还提供了新的AMGPerformance4Matic+全驱系统及可变扭矩分配功能。与V8引擎搭配的九速自动变速器也是首次出现在轿跑车和敞篷车上。S63百公里加速时间3.5秒，最高时速250公里，如果选装Driver’s套装可提升至300公里。而S65搭载一台6.0升V12双涡轮引擎，功率463千瓦/630马力，扭矩1000牛米，搭配七速自动变速器，百公里加速时间4.1秒，最高时速仍为250公里。除了S63和S65，S560搭载的V8双涡轮引擎功率345千瓦/469马力，扭矩700牛米，由于采用停缸技术，油耗进一步降低。无论是后驱还是全驱版本，百公里加速时间均为4.6秒。入门级车型S450搭载一台3.0升V6引擎，功率270千瓦/367马力，扭矩500牛米，轿跑车版本百公里加速时间5.5秒。S级轿跑车和敞篷车内部配备奔驰最新一代信息娱乐系统，标配无线充电，升级版魔幻车身控制悬挂，增加了更多安全设备。
Mercedes S-Class Coupe, Cabrio Bring Their OLEDs To Frankfurt
You could say Mercedes’ stand at the Frankfurt Motor Show is quite packed. the S-Class Coupe and Cabriolet now feature just about the same updates introduced earlier this year on the Sedan, but with an OLED twist. As standard, the two-door S-Class models are going to feature a total of 66 organic light-emitting diodes at the back.
The OLEDs (33 left + 33 right) would have to be the most significant change at the rear whereas the biggest novelty at the front is represented by the Panamericana grille reserved for the S63 and S65 models. Speaking of which, the former has made the transition from the old biturbo 5.5-liter V8 to a 4.0-liter engine, also a V8 with a pair of turbochargers. It might be down on displacement, but power is actually up by 27 hp (20 kW) to a monstrous 612 hp (450 kW) while torque stands at a respectable 664 lb-ft (900 Nm).
Aside from getting an engine transplant, the S63 also boasts a new AMG Performance 4Matic+ all-wheel drive system with variable torque distribution. It receives the V8 power from a nine-speed automatic transmission making its debut on both the coupe and cabrio. The new hardware helps the S63 cover the sprint to 62 mph (100 kph) in an amazing 3.5 seconds before topping out at 155 mph (250 kph) or 186 mph (300 kph) with the optional Driver’s Package.
The big daddy V12 6.0-liter biturbo in the S65 packs 630 hp (463 kW) and a mountain-moving 737 lb-ft (1,000 Nm). The immense power is delivered to the rear wheels through a seven-speed automatic transmission enabling the coupe to do the quick run in 4.1 seconds onto the same limited top speeds as the S63.
Elsewhere, the S560 has a biturbo V8 with 469 hp (345 kW) and 516 lb-ft (700 Nm). Mercedes mentions it’s one of the most economical V8 engines in the world and benefits from cylinder deactivation by turning off four of the cylinders and save fuel while under partial load. Both rear- and all-wheel-drive models run to 62 mph (100 kph) in 4.6 seconds when fitted with this engine.
Sitting at the bottom of the range is the 3.0-liter V6 in the S450 where it produces 367 hp (270 kW) and 369 lb-ft (500 Nm) for a sprint in a not-too-shabby 5.5 seconds in the case of the coupe.
All versions have been further modernized by getting Mercedes’ latest and greatest infotainment system, standard wireless charging, upgraded Magic Body Control suspension, and more safety tech than ever before.
