Just listen to its straight-six engine sing.
There was a time when the Nissan Skyline GT-R was an unassuming four-door sedan, rather than the two-door beast we know it as today. Launched in 1969 and codenamed PGC-10, only 832 examples of the original four-door Nissan Skyline GT-R were built until production ended in 1971, making it extremely rare. That means you’re very unlikely to see it on US roads, but talk show host Jay Leno managed to track one down and take it for a spin in the latest episode of Jay Leno’s Garage.
This particular 1969 Nissan Skyline GT-R comes courtesy of Orange County-based car dealership Original Rare. At the time, the GT-R was essentially a stripped-down version of the original Skyline designed to tear up the track. Unlike the current V6-powered Nissan GT-R, the four-door version was powered by a naturally aspirated 2.0-liter inline-six engine.
In stock form, it produced around 170 hp and was mated to a close-ratio five-speed manual gearbox. The unit utilizes a four-valve setup, which was ahead of its time in the 1960s. This particular example, however, runs on 45 mm Weber carburetors and features racing cams and a different set of headers. As a result, the power output has been cranked up to around 200 hp. Unlike the heavy all-wheel-drive GT-Rs that succeeded it, the original Hakosuka model was a lightweight rear-wheel drive machine built to dominate the racetrack. And that it did, as the four-door GT-R secured 33 consecutive race victories.
Weighing in at just 2,400 pounds, Leno even compares the car’s power-to-weight ratio to his McLaren F1, as it’s only 100 pounds heavier than the British hypercar but can seat four people. The video is worth watching just to hear the vintage GT-R's straight-six engine sing. Trust us, it sounds absolutely glorious.
