Mercedes S550 Plug-in Hybrid
It’s hard to find flaws in a Mercedes S-Class. In the past, power and comfort came at some price in terms of fuel efficiency. With the S550 Plug-in Hybrid, you get all the benefits of the Mercedes flagship sedan, but now with 20 miles of all-electric range and (depending on how you drive and charge) as much as 40 miles per gallon.
