All renters are responsible for tolls that are incurred during the trip Opt for nearly any of today's entry-luxury vehicles and you're in for a four-cylinder engine. Sure, most players in this space offer a more powerful six-cylinder option, but BMW's 3-series, Audi's A4, and Mercedes-Benz's C-class all come standard with a turbocharged inline-four. Most of these "base" powerplants deliver surprisingly hot performance, although that wasn't quite the case with the Benz—at least it wasn't until this year.
