Rate It: Infiniti’s All-Electric, Open-Wheel-Race-Car Design Study

Infiniti isn't really known for its open-wheel race cars. Despite that, the Japanese luxury brand made one anyway. Called Prototype 9, the design study was styled to look like a vintage Grand Prix racer.

If you're hoping this old-school-looking machine makes cool prewar engine noises, you might be disappointed. Power comes from a lithium-ion battery "from Nissan Motor Corporation's Advanced Powertrain Department" said to be good for approximately 148 horsepower and 236 lb.-ft. of torque. It can accelerate the 1962-pound car to 60 mph in under 6 seconds, according to Infiniti.

The prototype doesn't just have old-school looks; it was actually built the old-school way. The body was completely handmade, and the chassis underneath was made with a steel ladder frame. The suspension is based on leaf springs, the steering is non-power-assisted, and the brakes do without a booster (though disc brakes are used on all four corners).

Perhaps the best summary of this design study comes from Alfonso Albaisa, Infinit's senior vice president of global design:

"Prototype 9 celebrates the tradition of ingenuity, craftsmanship and passion of our forebears at Nissan Motor Corporation, on whose shoulders we stand today. It started as a discussion: What if INFINITI had created a race car in the 1940s? If one were to imagine an open-wheeled INFINITI racer on the famous circuits of the era, such as Japan's Tamagawa Speedway, what would that look like? The sketches were stunning and the idea so compelling that we had to produce a prototype. As other departments became aware of this, they volunteered their time to create a working vehicle."

Before we throw the spec sheet at you, let us know what you think about this unusual design study. Is this an exercise in breathtaking design, or is this just a backward prototype that will soon be forgotten?

I'll admit that Formula 1 has fallen off my radar recently, but it looks like I should start paying closer attention. yes

Infiniti also has some old history Indy racing. Sample from 2001.  But, which is more forgetable?  Infiniti or Indy Racing? Ha.  

Infiniti: the Rodney Dangerfied of lux cars.

as a werid aero guy... who has the following opinions:

I'd like to see more formula cars with minimal aero;  

I'd like to see more formula cars with simplified suspensions;   

I'd like to see more electric powered formula cars


so, this is like 300% approval from my end

If that thing had decent range, I'd rather daily drive it than a Leaf. Turn signals? I've got a functional left arm.

love the view from the back.  I would have preferred a track nose variant instead of what they gave it.  That's really the only possible complaint I have.

Love it.  I'd really like to see this one in the flesh.

It's "functional range" could be 30 miles and I'd still drive the hell out of it. It's like the EV 3-wheeler Morgan was gonna make but pulled back on at the last second.

I hope this is a sign that Infiniti is gonna do some more wild stuff in the near future.
