It’s easy to forget how dreary the mid- to late-1970s were. The oil shortage and new emissions regulations meant that cars with larger engines than their predecessors struggled to achieve the same performance. The Nissan Fairlady 240ZG was a benchmark of the carefree pre-oil crisis times, clocking a 0-400m (about a quarter-mile) time of 15.8 seconds. Mazda’s SA22 Savanna RX-7 was the first Japanese car to match the ZG’s time, though it came a whole six years later, the first bright spot in what would become a new era of performance. Happy Sevens Day from JNC!
