Illuminati Motor Works (IMW) “Seven”

The Latest episode of Translogic was devoted to Illuminati Motor Works (IMW) “Seven” from Illinois, the all-electric car that a few years ago participated in the Automotive X-Prize.

This strange looking vehicle is designed with aerodynamics in mind and the result is 207.5 MPGe – more than twice the number for Chevrolet Volt and Nissan LEAF.

Low drag helps to achieve more than 200 miles of range from just a 33 kWh battery pack (LiFePO4 type).

The Seven took second place in Automotive X-Prize and didn’t win the $10 million top prize, which would’ve helped to offset the cost of $200,000 (including $110,000 in parts and materials alone).

Such a unique car must have unique doors – two pairs of Falcon-style doors, but there are more unusual solutions like four steering wheels.

0-60 in 6.2 seconds and 130 mph top speed comes from AC induction liquid cooled electric motor feed from 100 kW inverter.

After the Automotive X-Prize competition ended, Seven spent his retirement for educational purposes.

It has a touch of Carmen Ghia in it…

Glad to see you covering a truly revolutionary EV for a change.

It’s definitely a very respectable combination of performance and efficiency.

I like it. I would definitely drive it.

It’s awesome, but what happens to the MPGe when they load if full of sound deadening, air bags, air conditioning…etc.

I bet a Volt and a Leaf would get much higher ratings if they were stripped down too…

The IMW ‘7’ is a very robustly built EV – it weighs 2,900 pounds, and I’m pretty sure that it could be built with those things and not gain any weight.

The most important factors to high efficiency is drivetrain efficiency (‘7’ has ~92% plug-to-wheel!) and aero drag. Weight is third on the list, and with an EV, there are two ways to regain some of the energy “invested” in the moving car – coasting and regen when you want to slow down.

“Such a unique car must have unique doors – two pairs of Falcon-style doors. . .”

Those are gull-style doors, not falcon-style doors. Gull-wing doors have only one hinge. Falcon-wing doors have a second hinge that allows them to be opened in tight parking spaces and when the car is resting on its roof after an accident, things that gull-wing doors can’t do with their single hinge design.

I think that four wheel steering might sound better than four steering wheels.

Is that what they meant? That makes much more sense!

The IMW ‘Seven’ is at about 2X as efficient as a typical EV. It achieves this by having a very efficient drivetrain – it has ~92% plug-to-wheel efficiency, which is about half the loss of a typical electric drivetrain. It does not have BMS; but rather they use bottom balancing to control charging. This keeps the cells much cooler, and the range improved. It coasts by default when you lift your right foot off the accelerator. This is – by far – the most efficient way to move the car. EV’s don’t idle and the AC induction motor in ‘7’ has no permanent magnets, so there is virtually no drag from the drivetrain. It has regen, switchable by the driver, for when they need to slow down. ‘Seven’ has very low aero drag – the Cd of the previous (silver X-Prize) body was measured at 0.23, and this carbon fiber body is significantly better. The design focused on minimizing the frontal area, as well. The long tapered tail is an important part of the low drag. It consumes just ~129Wh / mile at 60-70MPH on flat ground, in low wind conditions. This is outstanding – it is significantly lower than… Read more »

I’m surprised that so few EVs actually use AC induction motors. Tesla is famous for it, but that’s pretty much it – most use permanent magnet designs.

*and so is Tesla Motors…

when can I buy one?

Just as soon as an OEM has the nerve to build them. With the exception of Tesla, they are all depressingly conservative. But that is what happens when you are a huge company with lots of investors with no interest in your company, other than maximizing their returns.

Good ol’ corporations – protects the “owners” from losing their shirt, provides access to easy capital, and protects everyone involved from responsibility and innovation.
