Nissan Altima 2013's all-new exterior design starts with its wide, aggressive stance and dramatic front end styling. Though retaining the same wheelbase as the previous generation Nissan Altima, it has a wider front and rear track (+1.4 inches) and deeper fenders (+0.8 inches each side) – which combine with a crisp new .
As for the engines, a choice of two proven Altima powerplants – the 2.5-liter DOHC 4-cylinder and 3.5-liter DOHC V6 – are again offered for the new model year.
The Nissan Altima 2.5 S model includes 6-way power-adjustable driver’s seat, Advanced Drive-Assist™ Display, steering wheel-mounted audio controls, cruise control, Nissan Intelligent Key®, six speakers, auto on/off headlights, in-cabin microfilter, Tire Pressure Monitoring System with individual tire pressure readouts, and much more. Altima 3.5 S adds 18-inch wheels and tires, plus paddle shifters with manual mode.
The 2.5-liter QR25 engine has been redesigned to be lighter and more efficient. It now includes variable valve timing on both exhaust and intake camshafts, and the new intake system opens the valves at a higher rpm to help keep the torque curve flat. Featuring cutting-edge technology such as a new thermoplastic resin intake manifold, this engine simultaneously produced more power despite being lighter. Horsepower has increased by seven to an estimated 182 hp (from 175 hp), while torque remains the same at 180 lb-ft (est.). The advanced, award-winning VQ35DE 3.5-liter V6 remains rated at 270 horsepower (est.) and 258 lb-ft of torque (est.).
Targeted fuel economy for the Nissan Altima 2.5-liter 4-cylinder/CVT combination is 27 mpg city, 38 mpg highway and 31 mpg combined. Fuel economy for the 3.5-liter V6/CVT Altima is rated at 22 mpg city, 30 mpg highway and 25 mpg combined. Also contributing to the improved fuel efficiency are tires with reduced rolling resistance and a new regenerative alternator that only operates when the vehicle is coasting.
The all-new 2013 Nissan Altima is offered in four 2.5-liter engine equipped models, 2.5, 2.5 S, 2.5 SV and 2.5 SL, along with three 3.5-liter V6 equipped models, 3.5 S, 3.5 SV and 3.5 SL.
