Third gear. In the new C 63 S Coupe there are two ratios before it and four after, but it’s not until Third where you feel all the mighty thrust of its twin-turbo V8 engine.Reaching third gear under full throttle is pretty hard to achieve cruising Kings Cross on a Saturday night or idling along Parramatta Road five days a week, which is, realistically, how many AMGs sadly spend their time.It’s also impossible to savour legally unless you’re on the hallowed stretch of derestricted Stuart Highway north of Alice Springs, or on a racetrack like we thankfully were at the C 63 S Coupe’s Australian launch.Read the full Mercedes-Benz C63 S coupe 2016 review.
