Nissan's 2019 Altima will enter its sixth generation with an array of new features, including a pair of new engines, all-wheel drive, and rear automatic braking. Nissan unveiled its new midsize sedan at the New York International Auto Show.

As previously announced, Nissan is adding its driver-assisting ProPilot Assist feature as standard equipment on the SV, SL, and Platinum grades. The technology combines adaptive cruise control with a lane keeping system. Nissan has added it to 2018 models including the Leaf and Rogue.

Nissan is offering five trim grades, including the base S and SR.

Nissan will offer rear automatic braking that detects objects behind the vehicle and applies brakes when a driver is backing up to avoid a rear collision. The technology is part of the Nissan Safety Shield package that also includes automatic emergency braking with pedestrian detection, lane departure warning, radar-based blind spot warning, rear cross traffic alert, and high beam assist.

Two new engines include an optional 2.0-liter variable compression turbocharged inline-four cylinder that replaces the former 3.5-liter V-6. The new standard engine will be a 2.5-liter DOHC direct-injection inline-four cylinder engine. The new all-wheel-drive system is available on trims with this engine. The front-wheel-drive 2019 Altima will offer the 2.0-liter on the SR and Platinum trims.

The 2019 Altima is lower, longer, and wider than the outgoing model that includes available 19-inch wheels. Interior updates include standard a NissanConnect infotainment system and 8-inch multi-color touch display with Apple CarPlay and Android Auto.
