Speed-sensitive steering is standard on all versions. as is Nissan's Advanced Air Bag System. steel side-door guard beams and a tire pressure monitoring system. Beyond the engines and safety systems. the six varieties of Sentra start to diverge.

The Tech Package swaps in a Rockford Fosgate 8-speaker audio system and a rear-view monitor. The SE-R gets bigger brakes for more stopping power as well as sport-tuned springs and a rear spoiler. The SE-R Spec V gets even bigger brakes--12. 6-inches vs. the SE-R's 11. 7-inch--and a 25-mm front stabilizer bar. The sport-tuned suspension gives the Spec V a lower ride. with shocks and struts set for stiffer handling.
