Revolutions per millisecond
Two advanced Direct Injection engines, a 3.5L V-6 in the E350 and a 4.6L biturbo V-8 in the E550, operate with exceptional speed and precision. They can fire their spark plugs up to four times, and finely tune their fuel spray, all within a single millisecond. Quicker, leaner and cleaner all at once, they create a torrent of power and torque with only a trickle of emissions.
