The 2005 Nissan Altima 2.5 SL is more of an option package than its own trim, basically adding the features you get on the 3.5 SL onto the 2.5 S model. This front-wheel drive family sedan comes with a 175-hp, 2.5-liter DOHC inline-4 engine and 4-speed automatic. No manual transmission is offered. Like the 2.5 S, the 2005 Altima 2.5 SL comes with cruise control, power features, a CD player, and dual front airbags. Similar to the V6 model, the 2.5 SL adds leather upholstery, an 8-way power driver's seat, a CD changer, heated seats and mirrors, a trip computer, wheel-mounted audio controls, and automatic headlights.

Available options include a sunroof, foglights, a rear spoiler, a new optional navigation system, antilock brakes, and airbags. Dual front airbags earn 5-star crash ratings, but side impact bags are extra. Rear seats split-fold 60/40, and the trunk holds nearly 16 cubic feet and can be outfitted with a cargo net. Owners say the I4 engine is energetic and fun to drive, and the 2005 Altima 2.5 SL is comfortable, roomy, stylish, and good on gas. There are reports of rattling, a cheap-looking interior, and a hard-to-read radio display due to sunlight glare.
