Nissan's smallest cars juggle models and features for 2003. All Sentras are 4-cyl 4-dr sedans. The base XE and step-up GXE use a 126-hp 1.8-liter engine that meets the stricter emissions standards of last year's California-only CA model, which is dropped. New is the Limited Edition, basically a GXE with a 165-hp 2.5-liter engine, plus standard automatic transmission, ABS, and front side airbags. XE and GXE offer automatic as an option to 5-speed manual, and this year go from 14- to 15-inch standard wheels. Again topping the line are the sporty 2.5-liter SE-R and SE-R Spec V models with 165 and 175 hp, respectively, plus 6-speed manual transmission for the Spec V. SE-R boasts specific interior trim, sport suspension, 16-inch wheels, and 4-wheel disc brakes. Spec V has a tighter suspension, 17-inch wheels, unique exterior touches, and sport front seats, now with silver-color cloth inserts instead of red. Side airbags and ABS remain available for GXE, SE-R, and Spec V.
