Engine Specs

The 2025 Nissan Altima is the simplest Altima lineup in years: one 2.5-liter four-cylinder for every trim, a CVT, optional all-wheel drive, and four grades running from about $28,140 to $35,970 before destination. The turbo option is gone, but the interior tech took a step forward.

The N54 and N55 make identical factory numbers and get there differently: two small turbochargers against one twin-scroll unit with Valvetronic. The argument between them is about what each engine accepts afterwards.
