The base model for Nissan's sport compact economy sedan is the 2006 Nissan Sentra 1.8, carrying a 1.8-liter, 126-hp DOHC I4 engine and choice of standard 5-speed manual or 4-speed automatic.  There are virtually no changes from 2005.  Minimally outfitted, the 2006 Sentra 1.8 is a front-wheel drive, four-door sedan with front disc and rear drum brakes.  No ABS is available.  15-inch wheels carry all-season tires and dual front airbags.  Side airbags are not offered.

Convenience-oriented, the 2006 Sentra 1.8 does have cupholders, a storage console, and a front power outlet.  Air conditioning is optional, but you do get intermittent wipers, tilt steering wheel, a trunk light, and variable power steering.  A radio and CD player are optional as well.  The backseat is a bit cramped, but the seats do split-fold, and the trunk holds up to 12 cubic feet, which is decent for a compact.  The biggest draw to the 2006 Sentra 1.8 is its high 28/34 fuel economy, but drivers also feel it handles well and is energetic.  Some have reported numerous mechanical problems, but the biggest complaint centers on the flimsy cupholders.
