liftgate-type hatch. The styling was well-executed to appear muscular and purposeful while the liftgate-type station wagon appeared revolutionary in an era of traditional and upright rear tailgates. All featured a "Sportabout" emblem at the rear of the bodysides. The 2- and 4-door sedans were carryovers. The I6 engine was now standard across the range. A marketing promotion in the Spring made available a new fabric folding sunroof on specially equipped Hornets, as well as on the Gremlin. The opening roof feature was included with the purchase of whitewall tires, custom wheel covers, pinstripes or rally stripes, a light group, and a special visibility group. SC/360 The SC/360 was added for the 1971 model year as a compact 2-door muscle car that was intended as a follow-up to the 1969 SC Rambler. The tire pressure sticker on the first 1970 models built hinted at the availability of the 360 V8 engine. The standard engine for the SC/360 was AMC's V8. The SC/360 was distinguished by styled wheels, body striping, individual fully reclining front seats as well as other performance and appearance upgrades. In standard form, with a two-barrel carburetor, the 360 produced (gross) and the car was priced at just US$2,663 (about $40 below the 1971 Plymouth Duster 340). This combination was offered by AMC to achieve a 12.5:1 weight-to-horsepower ratio for insurance rate calculations. With the addition of the $199 "Go" package's four-barrel carburetor and ram-air induction, the SC's power increased to . Optional in place of the standard three-speed was a Hurst-shifted GM Borg-Warner Super T10 four-speed or an automatic transmission. Goodyear Polyglas D70x14 blackwall tires were standard, with upgrades including white lettered tires, a heavy-duty suspension package, and the Spicer "Twin-Grip" limited slip differential with 3.54:1 or 3.90:1 gears. Although the SC/360 could not compete with the holdover big-engined muscle cars, the SC combined respectable quickness (0 to 60 mph in 6.7 seconds) and the quarter mile (1320 feet, 402 m) dragstrip in 14.9 at with a taut suspension, big tires, and modest size; thus Motor Trend magazine described it as "just a plain gas to drive ... it handles like a dream." Hot Rod magazine ran the 1/4 mile an SC/360 with automatic transmission weighing in 14.80 seconds at 94.63 mph in "bone-stock form" and predicted that high 13s could be achieved "with little more than a rejet and recurve of the carb and distributor."
