The Nissan Sentra is powered by one of two advanced 4-cylinder engines. Most trims use a 1.8L 4-cylinder engine capable of 124 horsepower, while a 1.6L turbocharged 4-cylinder powers the SR Turbo and SR NISMO (Nissan Motorsport) models and puts out 188 horsepower. Standard on the Sentra S and NISMO manual is a 6-speed manual transmission, while all other trims feature a standard continuously variable transmission (CVT). Overall, the Sentra is fuel-efficient, with ratings of at least 30 mpg in combined city and highway driving even on cars equipped with manual transmissions.

The 2019 Sentra is divided into six different trim levels; S, SV, SR, SR Turbo, SL and NISMO. Starting with the base S model, though basic, includes several nice features and amenities. Standard items include 7-inch touchscreen display, rearview monitor, Bluetooth connectivity, remote entry and trunk release, power door locks, cruise control, intelligent automatic headlights and speed sensitive volume control for the stereo.

The next step up in the Sentra is the SV trim, which includes more upscale features such as NissanConnect with Mobile Apps, Apple CarPlay and Android Auto, premium cloth seats, intelligent key with push-button start, dual-zone temperature control and a 370Z inspired steering wheel.

The Sentra SR offers sharper styling, thanks to the 17-inch alloy wheels, a rear spoiler and LED headlights. Additional features include heated front seats with premium sport cloth trim, sport interior trim, fog lights, heated outside mirrors and intelligent cruise control. The SR Turbo is equipped like the SR, but its 188-hp turbocharged engine offers a significant power upgrade. Larger vented front disc brakes provide stopping power worthy of that extra power and a power moonroof is included as well.

The Sentra SL is the top-of-the-line trim and includes everything that comes on the SV, plus leather seating, power driver's seat, dual-zone climate control, a power moonroof, a Bose premium 8-speaker audio system and Sirius XM satellite radio.

Finally, Sentra NISMO keeps the same 1.8L engine as the SR Turbo but adds sport-tuned suspension and steering systems, 18-inch alloy wheels, an aerodynamics kit, special NISMO exterior trim and NISMO interior with red trim.

Several safety features are available on the Sentra. A blind spot warning system helps when changing lanes, while a rear cross traffic alert system makes backing out of parking spots easier. Other technology-driven safety features available on the Sentra include a forward emergency braking system and intelligent cruise control. Both systems use radar mounted at the front of the car to help avoid accidents.
