2013 Nissan Altima

2013 Nissan Altima: Powertrain-wise, the new QR25 2.5-liter four-cylinder features variable timing on both cams and a composite variable-volume intake manifold to broaden the torque curve. The engine is lighter and features a magnesium oil pan and a smart-charging alternator, and peak output increases from 170 hp and 175 lb-ft to 182/180. Combined with a next-gen CVT (wider ratio range, 40 percent less friction, improved control logic).

EPA fuel economy improves from 23/32 mpg to 27/38 (the unchanged VQ 3.5-liter V-6's EPA scores jump from 20/27 to 22/30, thanks to the CVT). A hybrid model will follow at an unspecified date. The CVT is the only transmission available regardless of engine choice. Production begins in May for June deliveries, and this lighter, quicker Altima appears to have what it takes to hold its position against the traditional front-runners.
