Both the 911T and 911E disappeared from the 1974 line-up as the 911 got its most serious makeover for the time being with arrival of fourth generation (1974-1977). Taking their place were a letter-free 911 and, finally in America, a Carrera. All featured versions of the 2.7-liter engine introduced earlier on the Carrera RS and new styling to accommodate energy-absorbing bumpers mandated by U.S. regulations.
The new body-coloured bumpers made the '74 911s look more contemporary and featured black rubber boots at the ends that looked like bellows. All the engines also adopted electronic fuel injection as emissions regulations grew even tighter. That put the output of the 911's 8.0-to-1 engine at 150 (DIN) bhp, and the 911S' and Carrera's 8.5-to-1 power plant at 175 (DIN) bhp.
The U.S. Carrera carried the same bodywork, wheels and tires as the European Carrera RS, but had to stay with the 911S engine to meet emissions. Other changes to all 911s included new aluminium and magnesium suspension components, new front seats with integrated head restraints, some other interior revisions and a rigid fiberglass top for the Targa.
Porsche eliminated the base 911 for 1975, narrowing the line to just the 911S and Carrera with one engine. More modifications were made to deal with emissions regulations and that hacked the output of the 2.7-liter six down to 165 (DIN) bhp in every state except California, where it was rated at just 160 bhp. These were not the quickiest 911s ever. The big news for '75 was taking place in Europe with the introduction of fabulous Turbo Carrera that did not make it to the United States that year, but it would for 1976.
The 911S was the only normally aspirated 911 for '76 and, virtually unchanged from '75, it was easy to overlook. In fact it was a joy to overlook as all eyes fixated on the 234-horsepower 930 (Porsche's internal model number) Turbo, which had one real, live turbocharger blowing into its big 3.0-liter engine, the 911 Turbo Carrera became one of the few great performance machines of the 1970s.
Except for a move of the Turbo from 15- to 16-inch wheels and tires, the 1977 911s were very much carryovers from '76. The front quarter windows no longer opened, revised ventilation system for more output, and there were new vacuum brake boosters, but otherwise status quo was maintained.
