Vintage, Jet-Powered Sports Car Hybrid Absolves Prius’ Sins
Old cars provide emotional experiences—they inspire not in spite of their inefficiencies, idiosyncrasies, and performance shortcomings, but because of them. As it is with interesting people, the hardships endured in a car’s making, the inherit flaws in their characters, and the ways they transcend these shortcomings are what make them extraordinary. These inspirations are what imbue an unliving object with a “soul”, that essential, elusive, and difficult-to-define ingredient present in all great machines.
Hybrids are the antithesis of our hobby because they are designed to be that way; they are mere conveyances engineered to be as unobtrusive and efficient as technologically possible, where common wisdom dictates the inclusion of any trace elements of this human spark would only detract from their core mission statements of MPG and ease of use above all else. We petrolisti reject this false narrative and the miserable cars that it produces.
Believe it or not, though, one of Toyota’s earliest hybrids wasn’t entirely incompatible with the concept of cool—in fact, it’s probably one of the coolest cars they ever built. Called the Sports 800 Gas Turbine Hybrid, it was heavily based on Toyota’s first-ever production sports car, from which the “Sports 800” part of its name came from. Predating the largely Yamaha-engineered 2000GT by a couple of years, the 800 was a tiny, pod-shaped thing with a Targa roof and a horizontally-opposed, air-cooled twin of 800 CC. A descendent of the Publica 700 economy car, the “Yota Hachi”, or “’Yota 8” as it’s affectionately known may have packed only 45 HP under its diminutive hood, but it didn’t weigh very much, either, contributing to a respectable 100 MPH top speed. A little over 3,000 were built during a four year run, and surviving cars are now pretty valuable.
A full decade later, in 1979, Toyota revealed the aforementioned hybrid version at that year’s Tokyo Motor Show. Equipped with a small, 30 HP turbine attached in parallel to a generator which in turn fed an electric motor running through a two-speed gearbox, there was no mechanical connection between the combustion motor and the driven wheels—a bit different, then, to how it’s more commonly done today.
With 33% less power and nearly half a ton more weight than its conventionally motivated siblings, the Turbine Hybrid must’ve been dead slow, and probably not even all that efficient, given the relatively narrow operational range and high thirst of jet engines. In an impressive engineering feat, though, Toyota scored big time with the experiment, as they were keen to show off their ever-increasing R&D capabilities. This was exemplified by the litany of pioneering Toyota tech introduced in the following decade—two examples of which I own myself: the world’s first mass-produced DOHC, 16-valve four cylinder that rests a few inches behind the driver’s seat of my MR2, and the incredibly over-engineered, paradigm-shifting LS400—my ’93 hasn’t used a single drop of oil in 25,000 miles of hard use. Both are inextricably and directly linked back to the teeny little jet car.
If Toyota put a turbine in the Prius today, I’d find a way to buy one tomorrow. Overcooked pasta chassis dynamics and an implied interest in bad indie rock be damned, a freakin’ jet engine washes away all automotive sins.
