Despite midsize sedan sales being on the decline, Nissan recently gave the Altima a new lease of life. The all-new 2019 model features a 2.0-liter variable-compression turbo four-cylinder, a revised 2.5-liter naturally aspirated engine, and, for the first time in the model's 26-year history, an AWD system. Its smaller sibling, the sensible Sentra, on the other hand, has received some updates for the 2019 model year before the next-generation model arrives next year.

Now on sale at dealerships, the 2019 Sentra starts at $17,790, plus an $895 destination and handling fee, which is an $800 increase over the outgoing model. As standard, the Sentra still comes with 16-inch steel wheels, a four-speaker audio system and Bluetooth connectivity. With the exception of the Sentra S base model, all trims now include a seven-inch NissanConnect infotainment system featuring Android Auto and Apple CarPlay.

Starting at $18,480, the Sentra SV can be equipped with a new SV Special Edition Package, which features 17-inch aluminum-alloy wheels, a glass moonroof, and rear disc brakes. It also includes illuminated visor mirrors, a Special Edition badge and Blind Spot Warning, Rear Cross Traffic Alert, and Intelligent Cruise Control assists.

Moving up the range, the Sentra SR, which starts at $20,590, offers a sportier appearance, with unique 17-inch 10-spoke aluminum-alloy wheels, lower body side sill extensions, rear spoiler with integrated LED brake light, fog lights and a chrome exhaust tip. If you want more luxury, the Santra SL starts at $23,020 and comes equipped with leather upholstery, heated front seats and a six-way power driver's seat. It also has an auto-dimming rearview mirror, a moonroof, HomeLink and an 8-speaker Bose audio system.

The range-topping Sentra Nismo starts at $25,840 and features unique styling inside and out. It also has sport-tuned suspension, a revised steering system and gripper tires wrapped around 18-inch alloy wheels.

All naturally aspirated Sentra models are powered by a 1.8-liter 4-cylinder engine that produces 124 horsepower, mated to an advanced Xtronic transmission. An optional six-speed manual transmission is also available for the Sentra S. The manual version increases the power output to 130 hp. The Sentra SR Turbo and Sentra Nismo feature a 1.6-liter Direct Injection Gasoline turbocharged engine that delivers 188 horsepower. The Sentra Nismo is available with either a six-speed manual or specially tuned Xtronic transmission.
