Best of both worlds with the 911S

The 1974 model year marked the first truly significant change to the 911 since its launch some 10 years earlier. A response to increasingly stringent legislation from the US, it introduced a raft of subtle but telling improvements that would go largely unaltered until production ceased some 15 years later.
 
Chunky build numbers over that period make what is now universally described as the G-Series, although technically that designation only applies to ’74 cars, one of the most widely available, affordable and, in many cases, unloved 911s of the air-cooled era. But the progress made by Porsche for the G-programme created a safer, more powerful, tractable, refined and reliable 911, yet one still blessed with the unique characteristics that by now had won over the world.
