I don't see any room for going to Costco or any real life thing like that,cant use it as it is. On the other hand,if 7/11 is your life style,it looks fine.
Putting the weight on the rear axles (as in a TWIKE) is great for cornering, but not for high speed on highways in truck turbulence or in gusty weather. The computer limits a TWIKE to 90 Km/h (55 mph) which is slow on European highways with cruising speeds of 120 km/h (75 mph).
In the TW4XP, weight is distributed lengthwise, to make higher speeds feel safe, too.
Apart from knowing perfectly what they are doing, these people actually listen to their customers !!!
I'm a 6 foot 4 inch (193 cm) Belgian and I've been a TWIKE pilot since 12 years (my TWIKE is an early model twin of the orange-yellow vehicle in the movie).
I have little headroom in the TWIKE, so I asked for 5cm more head and elbow room in the future model. The TW4XP provides that, so I'm very happy with it.
the Mitsubishi iMiev has a 16kWh pack and claims around 100mile range. that would be 160Wh/mile or more than 6miles per kWh.
don't kill the messenger but if your vehicle uses as much or more than commercial 1080kg (2380lbs) not particularly aerodynamic 4 seater cars then do you really know what you are doing?
doesn't it make sense that the4 cabin height and width should be reasonably minimal
interesting vehicle. either he is very small or the car could have been smaller. I would suggest a raised floor (smaller wind cross section) and a much smaller central column.
@DanFrederiksen You're right... Martin is not the tallest of people, the height of the vehicle therefore gives enough headroom for everybody. The central column houses the batteries. The ideal place for them: low and central weight distribution, well protected against impact.
@TW4XP unless he is midget small it looks like there is still too much headroom. the seats seem to indicate the same.
I understand the idea of the battery placement but you're not building a formula 1 car. if you placed the bulk of the batteries just behind the seats that would be excellent weight distribution too. is it lithium batteries? has to be lithium.
@DanFrederiksen Don't forget that this is a competition vehicle. We want to win the X Prize and need an excellent weight distribution, therefore the seats are mounted very low. The battery compartment is part of the load carrying structure, so we are not loosing any space with this, we need the structure anyway!
The production vehicle will have a hood that opens upwards as a door, this one will get fabric doors. The batteries are lithium-manganese. The steering is fully mechanical.
correct me if I am wrong but it's my impression that the xprize is about practicality combined with energy efficiency. not a race at all.
and it occurs to me that your vehicle is a 3 wheeler in which case the central line is certainly not the best weight distribution. likely the best is indeed just behind the driver low to the ground so as to balance on the wide span rear wheels
@DanFrederiksen You're right about the X Prize. But speed and acceleration are an important factor and in the end the fastest vehicle that meets the specifications will win the prize.
@TW4XP it's my impression that performance only matters as a tie breaker if the practicality, design appeal and energy efficiency is equal. if there is a 200mpge nice looking 4-seater then a 110mpge with ferrari performance wont beat it
as for structure I would think that a flat sandwich carbon fiber floor would be a near ideal base structure because it offers a smooth underside for vehicle aerodynamics, it's easy to make and ideal use of interior space. and can be quite strong with something like 20mm foam core. maybe even too stiff. fiber glass might be better
@DanFrederiksen Dan, there are zillions of possibilities to build such a vehicle. THIS is our solution and don't think a second that we don't know what we're doing! You will understand that I can't go into more detail ... this is still a prototype and we have competitors! Not just for the race, also for the production later.
Have a look on our website to get a better idea of how and why we are doing this and what our background is.

GUYS..... I logged on to check out your vehicle... not listen to crappy rock music. Who made this video??????

Vehicle is not aerodynamic. What is the point of the open wheel wells IN BACK?
TogetherinParis 1 year ago
@TogetherinParis Smoothness is most important at the FRONT
At the very rear the car's profile can be as rough as you like, because the airflow has become turbulent after the widest point of the car

btw don't feel bad, none of the other teams know what they are doing either. team illuminati certainly have a funky design : )
your design is pretty good with a few tweaks

btw what kind of Wh/mile numbers can you get with it for highway speeds? if it can go that fast

@DanFrederiksen We're still testing, but we expect something of the order of 5 miles per kWh.

Hallo Martin, hallo Barbara,
sehr schönes neues Video!
Und der TW4XP ist ja auch was für Sitzriesen...
Die Parallelfahrt TWIKE 3 zum TW4XP zeigt den Wandel sehr anschaulich.
Liebe Grüße kb
