2018 Nissan Altima 3.5 SL Specs

The 3.5 SL is the only trim to receive the more powerful 3.5 V6 engine, which pairs with the larger 18-inch alloy wheels and paddle shifters. Standard features on this top-tier trim comprise LED headlights, adaptive cruise control, front and rear sonar, and a seven-inch touchscreen infotainment system that supports Apple CarPlay and Android Auto. NissanConnect Services and voice recognition, as well as SiriusXM traffic are added, and the radio monitor is upgraded to seven inches. A power sliding glass moonroof rounds out the 3.5 SL’s offering. While it costs $4,000 more than the 2.5 SL, this trim is also the only one that comes standard with smartphone integration, making it the most appealing to today’s buyers.
