10 JDM Cars That Were Ahead Of Their Time

Throughout Japan's golden carmaking era in the '80s and '90s, the country's automakers picked up a reputation for building the most technologically advanced cars in the world. However, they were building futuristic cars long before that, even if some of them have slipped under the radar of most enthusiasts. In fact, the country's history of automotive innovation stretches right back to the years following World War II, when Japan was in the early stages of transforming itself into the economic powerhouse it is today.

From the obscure electric vehicle produced in the late '40s to the legendary tuner car that forced European manufacturers to step up their game in the early '90s, there are many Japanese market cars that could be considered ahead of their time. We've picked out a selection of 10 of the best, covering both the best-known icons and a few forgotten gems that almost no one remembers.

EVs have a much longer history than many people give them credit for. The first EV to hit Japanese roads was the Tama Electric, which was unveiled in 1947, as Japanese companies were just beginning to rebuild after World War II. At the time, oil was in very short supply, but there was a ready supply of electricity as the demand from households was extremely low. The logical response from automakers was to build cars to take advantage of that plentiful supply, and the Tama Electric was just one of several prototype electric vehicles built with support from the Japanese government.

Official tests proved it to be the top performer out of those initial cars, with a range of around 40 miles and a top speed of around 22 mph. Not much, but enough for the Tama to function as a taxi until 1951, by which time oil supplies were increasing and combustion-powered cars were becoming the standard. 

With little need to improve EV technology as gas became the go-to source of power, the project was eventually abandoned. Tama would eventually be renamed Prince Motors and merge with Nissan, and today the original Tama Electric is preserved in Nissan's heritage collection.

The Toyota Sera was a small, futuristic sports car sold only in the Japanese domestic market. First unveiled in concept form, the production version hit dealerships in 1990, just as Japan's economic boom was peaking. It was based on the Starlet hatchback, but unlike its everyday counterpart, the Sera featured innovations like gullwing doors, a wrap-around glass cabin, and plenty of optional tech.

Perhaps the most unique option was the ten speaker surround-sound system, which included a dedicated subwoofer in the trunk. The system also made use of the cabin's glass canopy, with certain speakers rotating to bounce sound off a different part of the glass to create an experience supposedly like listening to live music. The car proved a hit at first, but after a couple of years on the market, the Japanese recession had slowed sales down to a fraction of their initial volumes. The Sera was eventually axed in 1995, and as innovative as it was, its unique audio system was never reproduced in any other production model.

However, its dihedral gullwing doors did end up proving to be ahead of the curve. They eventually inspired Gordon Murray, who noticed the car while he was working on the McLaren F1. Murray explained to Car Magazine that he drove past a Sera every day and eventually borrowed one, using its layout as the foundation for the era-defining supercar's gullwing design.

The Toyota Prius was the first production hybrid vehicle to hit the mainstream, but the Honda Insight trumps it in many respects, even though it never became as popular. Most importantly for any hybrid, it was significantly more efficient than the Prius, with 70 mpg achievable from its electrically assisted three-cylinder engine. That's a feat that even today's most fuel-sipping hybrids can't achieve -– the top-scoring model in our most efficient cars of 2023 only manages 54 mpg. The Insight is now over 20 years old, yet it still beats anything on the market today by a large margin.

This was in part down to its aerodynamic shape. Honda's engineers went to great lengths to ensure that the car was as slippery as possible, even going as far as partially covering the rear wheels to reduce drag. The interior was also stripped out to save weight, with only the bare necessities and little in the way of creature comforts. The car's laser focus on efficiency above all else was probably the main reason for its lack of commercial success compared to the Prius, but it resulted in fuel efficiency figures that, even two decades on, remain ahead of the pack.

At first glance, hydrogen-powered cars seem like an obvious answer to the current climate concerns — they boast similar ranges to modern gas cars, can be refueled in a few minutes, and produce no harmful emissions. However, they're far from a perfect solution. Concerns persist about the environmental impact of leaks and the process of hydrogen production itself, but the biggest issue, for now, is that there's simply not enough refueling infrastructure built to sustain a network of cars.

The Honda Clarity Fuel Cell is one of the latest attempts at marketing a hydrogen car to the masses and went on sale in Japan in 2016. SlashGear drove a Clarity a year later and found it to be, essentially, a decent Honda sedan. That's a good thing because, despite what some automakers seem to think, not all alternative fuel vehicles need to look like they come from outer space. That said, it's not entirely free from awkwardly angular styling, although it's not as ugly as the first generation Toyota Mirai.

The Clarity Fuel Cell was discontinued in 2021 due to low sales numbers, but that's hardly a surprise. After all, the only place in the continental U.S. with hydrogen fueling stations was California, so driving the car out of state was impossible. Work is continuing on improving hydrogen infrastructure across the U.S. and globally, so it seems that the Clarity was simply ahead of its time. For now, its potential remains largely unfilled.

If there's one JDM car that has become the poster child for being ahead of its time, it's Godzilla. Nissan's benchmark Skyline R32 GT-R first debuted in 1989 and, like all Japanese cars of its time, was officially rated at 276 horsepower thanks to a gentleman's agreement. However, its true output was much higher, and tuners quickly found that they could modify the RB26DETT to produce horsepower figures that were unheard of for a Japanese car at the time.

The GT-R's capabilities stretched to more than just raw power, however. Its Super HICAS four-wheel steering system and ATTESSA E-TS four-wheel drive system were a cut above anything seen on a Japanese car and among the most advanced in the world. In total, over 40,000 examples of the car would be made, with a small number heading to Australia but the vast majority destined for the Japanese market. 

In the decades since its debut, the R32 GT-R has become one of the most desirable JDM cars on the collector market, and for good reason. After all, it helped usher in a new era of Japanese engineering dominance, and with the right modifications, can still go toe-to-toe with many modern supercars today.
