Launched in Japan in March 1978 as the Savanna RX-7, replacing the RX-3, the first-generation car paired a 1.1-litre twin-rotor 12A engine with a very light body (under 1,100 kg) and a near-even front/rear weight distribution.[1] It was a purer, smaller car than either generation that followed it: a strict two-seater with pop-up headlights, sold in the US and Europe on the novelty of a rotary engine that revved like nothing else on sale at the price.
The Wikipedia article covering this generation states power in US horsepower without specifying gross or net, and gives 0–60 mph acceleration figures with no metric 0–100 km/h equivalent published anywhere in the source; both are left out here rather than converted, per this site’s policy against converting between quantities that were never measured as each other.
