A team from Istanbul University developed the first Turkish-made electric car with up to 500 km of range.

It’s called T-1 and last month it traveled some 436 km from Istanbul to Ankara (see video story).

This is a three-seater (2+1) that weighs just 500 kg. Top speed is 120 km/h. The battery pack stores some 30 kWh of energy, so this 500 km range seems optimistic to us. Charging takes ~ 4 hours.

Energy usage after 4,650 km was 307 kWh, which is less than 7 kWh/100 km (62 miles).

As this is a prototype with composite structure, the cost is very high – roughly $200,000.

    I’m super happy to see a nation like Turkey proud of a tech accomplishment. Keep them coming, it’s refreshing to hear of this kind of development rather than wars, conflicts and dissent.

    It would be great to see an EV industry spring up so close to the traditional “Mecca” of the oil economy.

    Funny how projects like this and Masdar City an ecopia green city in the middle of the Abu Dhabi desert don’t get the press that fanaticism and violence do in our modern media.

    Where are the headlights hiding?

    1. It is a prototype – there is a place for them. Don’t worry, it can have headlights.

    2. Rob says:

      It doesn’t need them. You get two vans free with purchase 🙂

    Nice job. Throw some solar panels on there and collect some electricity while driving.

  4. Awesome – thanks for posting!

    We could have much longer range with today’s batteries – it comes down to the efficiency of the car itself. Most of the energy used by any car goes into pushing the air out of the way, and the turbulence this creates. A typical car shifts several TONS of air aside every mile it travels.

    At just ~30MPH the aero drag is HALF of the load on the drivetrain. And at just ~55MPH, it is THREE QUARTERS.

    Lowering the Cd (coefficient of drag) on a car is a matter of shaping the outside of the car properly, and once this is designed, it costs virtually the same to build as a high drag car.

    Going farther on the same battery means that cars can either go a lot farther and/or cost less to go the same range. EV’s like the EV1 and like the Illuminati Motor Works ‘Seven’ use HALF the energy (or less) than a typical EV; largely because they are low drag.

    Using half the energy means it goes twice as far on the same battery. And batteries are less stressed, and stay cooler. They get charged half as often, so the battery will likely last a lot longer. And obviously, they cost even less to operate.

    I think this car is entirely plausible. I wish them all the success!

    1. Mint says:

      The drag of this car is low not only because of a low Cd, but also a low frontal area because it’s a tiny car.

      The market for cars like this is really tiny. IMO, it’s much more of an experiment rather than a prototype for a viable product.

      The bigger the vehicle class, and the higher the performance, the more competitive a consumer EV is compared to gas.

      1. The Cd is far more important than the frontal area: the Tesla Model S has the *same* CdA as the Prius.

        It seats 3 people, so it would have plenty of practical uses. It is not unlike the VW XL-1 but with three seats instead of two.

        At about 111Wh/mile this Yerel T-1 is much more efficient than most EV’s.

        1. Dr. Kenneth Noisewater says:

          Cd is equivalent in importance to A. It’s just harder to improve.

          This is a pretty neat project, and certainly could compete with concepts like the Elio or Tango, when costs come down to more realistic levels.

          1. Cd is easier to improve than frontal area. There is only so small you can make a car.

            The sides of the Yerel T1 are not tapered – if the rear wheel track was reduced, then the Cd could be lowered even more – by as much as 40% lower.

        2. Mint says:

          Practicality is one thing, but desire is what sells cars, especially new cars (anyone being practical would buy used).

          Economical 2-seaters/3-seaters don’t sell, despite many attempts to do so.

          Something like this would not do well in crash tests, either.

          1. martinwinlow says:

            Desire can only take you as far as you have the money to cover it. If (when) oil starts to sky-rocket, suddenly (shock, horror) everyone will be wanting cars that cost less than ICEV cost to run. Ultimately, that means small. MW

          2. Crash worthiness is something that is largely engineered – you cannot just look at a car and determine its ability to protect the occupants in a crash.

            Deflection away from the impact is an under appreciated method of achieving very good protection.

    Istanbul seems like a great place to buy an EV. I was there last year and gas was $12/gallon!

  6. LuStuccc says:

    Students can do it but big cars companies with billion$ cannot?!?

    1. Mr. M says:

      Sure they can build a two seater with 0-62 mph time of 20s, 30kWh Battery, Moncoque, no Airbags, ESP, ABS, … (but with seatbelts) for (lets be fair) 80k$ (instead of 200k$) and NO Trunk. But i think the market is not that big, if you can already buy a model s for around the same price, more range, trunk, decent safety equipment, etc.

      What would you really prefer buying something like this over a model s?

      1. Lustuccc says:

        Sure with millions and millions more, Big Car cannot adress these issues… doh!

  7. BraveLilToaster says:

    Sure they can. But the compromises that go into this car basically make it nearly unmarketable. Just take everything that’s bad about the Miata , and then take away everything that’s good about it, like the acceleration, handling, air conditioning, and convertible roof, and you’ll have a car that every reviewer will pan from here to Baghdad. Trust me, we don’t need that. There’s a saying in engineering: perfect is the enemy of good. I’d rather take my Leaf and tell everyone that it drives like a normal hatchback than have the world think that EVs are impractical.

    1. Lustuccc says:

      15 Years of supposed R&D and many billions after, the giant cars companies cannot do even half of what Tesla acheived. of course…

  8. Rob says:

    I like it!
    It looks good!
    I’d bin the back seat and use the space for storage. It would be nice if they could up the performance a bit.

  9. Blueberry Blipblop says:

    Not even one video withot music where you can hear the sound of the car. Why has video editing become more important than what is in the video clips?

  10. BraveLilToaster says:

    After watching a few of the videos, I know the secret to that 7 kWh/100 km efficiency.

    Oh, sure, there’s the super lightweighting, the aerodynamics, the stripped and uncomfortable interior. But just as importantly, they weren’t keeping up with traffic on the highway.

  11. martinwinlow says:

    I assume 500kg is *without* the battery as that would only leave about 200kg for the car! Possible, I suppose – can someone confirm? Nice effort either way!

    1. tanntas says:

      Hey Martin, I am one of the member of the team, weight of the car is 500 kg including 30 kWh battery.

      The point of the project was to build an efficient vehicle. So, we carefully designed the vehicle to keep the weight lightest as possible.

      The weight of the battery pack is 180 kg and the car has carbon fiber monocoque structure…
