The Volkswagen Karmann Ghia received its final engine update in 1971 – the twin-port 1585 cc flat-four, now producing 60 bhp. The compression ratio remained at 7.5:1, but the crankcase was stronger, the aluminum oil cooler more efficient and top speed now near 90 mph. A thermostat now controlled the engine air preheating system. Defroster outlets were larger and felt carpets were new.

The twin-port engine offered a useful increase in power and was accompanied by front disc and rear drum dual-circuit brakes as well as a 12-volt electrical system. The rear tread was wider and a sway bar included with softer rear springs. With two double-jointed constant velocity joints on each rear axle and trailing arms, the rear suspension eliminated the rear wheel “tuck under” problem with earlier cars when they were cornered hard. However, the Super Beetle’s McPherson strut front suspension never made it to Karmann Ghia models, which continued to have torsion bar suspension all round.

A 3-speed semi-automatic transmission (called Automatic Stick Shift) was still available for the 1971 Karmann Ghia Coupe and Convertible, but itit was never popular and quite a few cars were subsequently fitted with 4-speed manual gearboxes.

Coupe sales declined to 21,133 but Convertible production increased to 6565. Prices rose slightly again, with the 1971 Volkswagen Karmann Ghia Coupe costing $2575 and the Convertible $2750.

Exterior colors increased to 12 in number, with perhaps the best range available so far. They were Lemon Yellow, Amber, Blood Orange, Bahia Red, Black, Adriatic Blue, Irish Green, Willow Green, Light Ivory, Silver Metallic, Gemini Blue Metallic and Gold Metallic.
