Sweet mother of all that is holy, this 402 hp M278 twin turbo 4.6 liter is a barrel of well engineered monkeys. Roads in the CL550, replaces the naturally aspirated 382 hp 5.5 liter still being sold as you read this. Acceleration to 60 mph now ought to take just 5.0 seconds, and we wouldn’t be surprised if someone sneaks into the highest fours.
