Engine and Transmission
Underhood is the 2.5-liter QR25DE inline-four, which is also used in the Altima. In the SE-R, it makes 177 horsepower and 172 pound-feet of torque. The Spec V has a higher compression ratio (10.5:1 versus 9.6), a 7000-rpm redline (up from 6200), and unique intake and exhaust manifolds, connecting rods, pistons, and camshafts to increase output to 200 horsepower and 180 pound-feet. The CVT in the SE-R works in automatic mode, or the driver can use steering-wheel-mounted shift paddles to operate in manumatic mode. SE-R engines will run on regular unleaded gasoline; the Spec V requires premium.
The SE-R Spec V adds larger brakes, sport-tuned shocks and struts, lowered ride height, larger front stabilizer bar, reinforced upper cowl, trunk-mounted V-brace, and red front seatbelts.
