Details about the next-generation Mercedes-AMG E63 and E63 S have been leaked online ahead of its debut later this year.
Under the bonnet, the new E63 and E63 S will ditch the current model’s 5.5-litre twin-turbo V8. In its place will be a retuned version of the 4.0-litre twin-turbo that made its debut in the Mercedes-AMG GT coupe, and which also motivates the C63 and C63 S models.
If the Russian dealer brochure posted overnight on GermanCar4um is accurate, the new E63 will have 420kW of power and 750Nm of torque at its disposal.
That’s good enough to haul the mid-size model from 0-100km/h in under 3.7 seconds. Top speed will be electronically limited to 250km/h, while in official EU testing, the new car will have a fuel economy rating of 8.6L/100km.
While that’s impressive by itself, the E63 S will have substantially more spuds at its beck and call, with the brochure stating a maximum output of 450kW of power and 850Nm of torque. This cuts the 0-100km/h time down to 3.5 seconds, while the electronically limited top speed and fuel economy figures are unchanged at 250km/h and 8.6L/100km, respectively.
At present, the most powerful version of AMG’s 4.0-litre twin-turbo V8 has 375kW of power and 700Nm of torque against its name.
Meanwhile, the twin-turbocharged 5.5-litre V8 in the current E63 S cranks out 430kW/800Nm, and can hustle from 0-100km/h in 4.1 seconds.
According to the brochure, the new E63 and E63 S will both come fitted with a nine-speed MCT automatic transmission, electronic locking rear differential, and Air Body Control suspension as standard.
