This new episode of Head 2 Head sees Motor Trend’s Jonny Lieberman and Mike Shaffer team up to compare a couple of sledgehammer saloons: the Mercedes E 63 AMG 4MATIC S-Model and BMW’s M5 Competition Package.
As well as optimized chassis settings, the Competition Package’s presence means output from that 4.4-litre biturbo V8 powerplant is raised to 423 kW (575 hp) and 680 Nm of torque, while the meatier E 63 AMG 4MATIC S-Model enjoys a 5.5-litre bi-turbo V8 producing 430 kW (585 hp) and 800 Nm.
