2019 Mercedes-Benz S560e Has Unique Talents but Isn't the Star of the Lineup

2019 Mercedes-Benz S560e. The Mercedes-Benz S-class sits at the top of its rarefied segment, with unmatched comfort and leading-edge technology that put it a step ahead of the competition from BMW and Audi. Now Stuttgart is rolling out a plug-in hybrid, the S560e, and the question is whether it brings further glory to the line or fails to support its good name.

This is the second plug-in S-class, and this new version has a lithium-ion battery that is considerably larger than the one in the previous S-class hybrid. With its new battery, Mercedes says this plug-in hybrid can travel 30 miles without starting the internal-combustion engine. And the electric motor can silently propel the S560e at speeds up to 80 mph. Beyond that, the familiar twin-turbocharged 3.0-liter V-6 comes to life; it contributes 362 horsepower. It also powers the nonhybrid S450, yet it's not as silky smooth as the next-generation 3.0-liter inline-six that's already used in some Europe-market versions of the S-class.

Together with its 121-hp electric motor, the S560e produces an impressive total system output of 469 horsepower, 33 more horses than the previous S550e's 436. That's sufficient for a sprint from zero to 60 mph of just under five seconds, according to Mercedes. Still, that acceleration is not nearly as good as that of the V-8-powered nonhybrid S560, which needed just 4.2 seconds to get to 60 mph by our measure. One factor may be the weight of the S560e—this plug-in hybrid weighs roughly as much as the 12-cylinder S600. Read more about the 2019 Mercedes-Benz S560e...
