Nissan's flagship sedan shares an underskin design with the slightly smaller and less costly Altima. Maxima comes in sporty SE and luxury-oriented SL models, both with a 265-hp V6. Altima offers this same engine, but Maxima's is tuned for more power. SE comes with a 6-speed manual transmission. Optional on SE and standard on SL is a 5-speed automatic with manual shift gate. Both models come with ABS, front side airbags, and curtain side airbags. Traction control is standard. An antiskid system is optional with automatic transmission. Leather upholstery is standard for SL, optional for SE. Nissan's Skyview roof of dual tinted-glass panels is standard. A conventional sunroof is available. Also optional are a navigation system; heated front seats; and an Elite Package with full-length center console, twin rear bucket seats instead of a three-passenger bench, and power rear-window sunshade. Wireless cell phone connection is a new option for '06.
