The S-Class – previously known as the “Special” Class – is Merc’s full-sized coupe and sedan, a flagship luxury vehicle that promises the highest levels of refinement, the finest materials, and the most advanced technology offered by the German automaker. Following its reintroduction in 1972, there have been six generations of the S-Class, with the latest generation introduced for the 2014 model year. But now, the calendar is telling me the date is 2017, and all that luxury, technology, and opulence can be had with some green sensibilities as well. Merc’s latest entry in this segment is the S 560 e, the successor to the S 550 e, which once again seeks to find a balance of both long range and a local emission-free motoring, all with that characteristic Mercedes gloss. The S 560 e just broke cover at the Frankfurt Motor Show, and it when it hits U.S. dealers in 2019, it’s expected to arrive with a twist-happy 3.0-liter V-6, 25 miles of all-electric range, a nine-speed automatic transmission, and plenty of Eco-focused features, plus all the traditional luxury bits, of course.
