2013 Altima: Next Generation Xtronic CVT, Redesigned Engine
The 2013 Nissan Altima is an evolution of a great car into a better one! For 2013, Nissan engineers kept the same basic dimensions as the previous generation but gave new attention to aerodynamic design, which helped give the new Altima a premium appearance. The new body-in-white features a new front tower strut brace like found on sports cars, and additional rear structural support built into the rear parcel shelf – enhancing structural rigidity and lateral handling response. At the same time, overall body weight has been reduced through utilizing aluminum hood and bumper reinforcements and expanded use of high-tensile steel. In addition, more than half the steel in the body is “high strength steel.” Total vehicle weight has been reduced by around 80 pounds.
The 2013 Altima’s exterior color palette has been selected to emphasize presence and quality feel. A new character color, Storm Blue, joins new Altima colors Cayenne Red, Pearl White and Java Metallic, and carryover colors Brilliant Silver, Saharan Stone, Metallic Slate and Super Black.
Altima’s improved version of Nissan’s QR25 engine reduces approximately 11 pounds while adding seven horsepower to 182 hp. The design adds 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. Torque is rated at 180 lb-ft. Other revisions include an aluminum exhaust manifold cover (previously steel), a more efficient starter motor, and thinner cylinder head walls.
The 2013 Altima’s advanced Xtronic CVT® design raises the standard in class yet again, providing a premium driving experience and rewarding acceleration that evokes the feeling of a higher class sedan.
A full 70 percent of the parts have been redesigned, which along with a downsized oil pump, lower oil level and low viscosity oil results in up to 40 percent reduction in internal friction (versus the previous design).
When starting from a full stop the continuously varying ratios (compared to step automatic transmissions) results in seamless acceleration. And, when accelerating while passing, acceleration is smooth and confidence-inspiring due to no stepped gear changes and minimized shift shock.
The new intelligent CVT logic also includes a Lift Foot Hold function that holds the gear ratio if the accelerator pedal is momentarily released and then reapplied, such as when merging onto a freeway; and a Brake Downshift function that “downshifts” the transmission when braking is applied before entering a corner, so re-acceleration is enhanced when exiting the corner because the CVT is already in a lower gear ratio.
