At the time of its release, the Environmental Protection Agency (EPA) gave the Sentra MPG the highest gasoline mileage for gasoline powered cars marketed at that time, 43 miles per gallon in city and 58 miles per gallon in highway, a combined 48 miles per gallon. Curb weight of only 1875 pounds helped it to achieve that number. The Sentra MPG featured a three-way exhaust catalyst and an electronically controlled fuel metering unit to monitor the air-fuel mixture automatically and make adjustments to boost fuel mileage. Trim levels were Standard, Deluxe and XE, while price range were between US$4,949 for the base two-door sedan up to US$6,899 for the two-door XE hatchback coupe. Standard equipment on all models were four-wheel independent suspension, front disc brakes and rear drums, rack and pinion steering, maintenance free battery, rear ashtray and bucket seats. Deluxe models added halogen headlamps, remote-locking gas filler door, carpeted trunk and rear wiper-washer on the wagon. Deluxe and XE offered tinted glass, trip odometer, vanity mirror, dual remote mirrors and door trim. XE offered cut pile carpeting, analogue quartz clock, remote rear window opener, low-fuel warning light, AM-FM Clarion stereo radio, power steering, tachometer and 155/13 whitewall radial tires.

Also, the 1.5 L was replaced by a 1.6 L E16 as the standard engine, available with a five-speed manual or three-speed automatic. Later that year the Sentra also received an electronically controlled carburetor. In April 1985, Nissan started production of the Sentra in the Smyrna, Tennessee plant, after a US$85 million investment. The only body style manufactured in the US was the two-door sedan. The 1985 model-year received aerodynamically styled headlamps, a revised grille and blackwall tires. An SE option was introduced as two-door hatchback model, with alloy wheels, black lower body paint and black out grille. An automatic transmission was optional on all Sentras except the
