only available transmission was a 4-speed automatic. These models offered the appearance of a standard Sentra coupled with the power of an SE-R. 2004 model year refresh In 2003, Nissan launched the 2004 model year which saw a minor facelift for all Sentras. Transmission gearing and build quality was improved for the 2004–2006 SE-R Spec V which resulted in a quicker quarter-mile time of 15.2 seconds. The now automatic only SE-R (starting in MY2003) was capable of a quarter-mile time of 16.0 seconds. The SE-R & Spec-V retained the dark housing headlights and gained "smoked-out" or darkened tail lights in the rear. 1.8 Special Edition The Special Edition was produced for model years 2005 and 2006. Exterior features included a rear spoiler, fog lights, SE-R-style front grille, and 16-inch alloy wheels borrowed from the SE-R. Interior features included 320-watt six-disc Rockford Fosgate nine-speaker sound system, and a charcoal cloth interior and leather-wrapped wheel borrowed from the SE-R model. The only available engine was the QG18DE paired with either a four-speed automatic or a very limited quantity five-speed manual.

The 2004 model year also featured a new style of tail-light which is reminiscent of the Skyline GT-R's quadruple taillights. Volcanic Orange, an exclusive color for the SE-R and Spec V trim was available for 2004–2006 models. The interior was also redesigned. Starting in 2005, the SE-R embossed "goose-neck" shifter handle from the previous models was replaced by an all black, leather stitched ball-top shifter. The original two-tone interior cloth found in previous Spec V models was changed to all-black mesh for the 2005 & 2006 model years. A big brake option featuring Brembo four-piston calipers up front, 12" vented front discs and upgraded 10.9" rear discs were available for 2004–2006 Spec V models. ABS was unavailable with this option from the factory.
