Technologies Used -
  1. Spot Cooling -
    The Immortus needs to use little energy, and air-conditioning is not an option. Therefore, the driver will be cooled with the strategic application of vented air. The knowhow that comes from this will be of value to other car makes looking to increase efficiency via better cooling approaches.
  2. No Side Mirrors -
    The Immortus, to be aerodynamic, will not have side mirrors. Instead, cameras in the rear of the vehicle will be used with screens inside to allow the driver to perceive the events behind. The knowhow and system developed doing this prove a potential to be superior to current systems. 
  3. Regenerative Shock Absorbers -
    Traditionally an academic pursuit these shock absorbers are so ideal for a solar car that they are being developed to take them from the theorised to the applied.
  4. Air Cooling -
    The Immortus must be light and always needs to charge and discharge. This means effective battery management and the effective use of air cooling as opposed to liquid cooling, which is heavier and also more prone to failure due to the extra parts.

Notes -
  1. This car is inspired by the world portrayed in post-apocalyptic movies, the Immortus is designed to exhibit a toughness that no other car has: endurance
  2. The ability to run on the power of the sun and store the energy for later use make it a car of practically infinite endurance. As long as the sun shines the Immortus lives...
  3. The initial model will be a specialised vehicle to showcase this new technology, which will be presented as a high-end custom vehicle for high network individuals.
  4. Looking at Tesla, EVX Ventures hope to replicate its strategy by first offering the Immortus as a luxury limited edition before affording it to the mainstream.
  5. Electric vehicles still need to be plugged into a power source to charge and often that main power grid is a dirty, rather than clean and renewable energy source. With solar powered vehicles there are no external plug ins and the whole system, including power and refill costs, steps beyond that of previous electric vehicles.
  6. The Immortus is currently our technology development platform where a 'concurrent engineering' approach is utilized. This approach has proven to be very economical and rapidly yields spin-off peripheral technologies with multi-industry applications.
    This project was a Finalist for Singularity University's Australian & New Zealand Global Impact Competition 2014. 
  7.  EVX is an early stage venture focused in the R&D and commercialization of high performance solar and electric vehicle technologies. EVX's ultimate vision is to make self-powering cars the future of transportation.
  8. EVX is supported by the research and development team at Swinburne University of Technology, one of the leading electric vehicle research groups in the world. Founded in Melbourne, Australia.

Notes -
  1. The Tesla Model V/5 is 12.5% smaller than Tesla Model E/3 and 30% smaller than Tesla Model S.
  2. The car is specifically made for developing economies, thence, the ground clearance is kept relatively high and top speed is kept within appropriate legal limits.
  3. Since the market for such a car would be predominately limited to metro-cities in developing economies, the range is not kept too high for long distance routes and is preferably useful for daily commotion within a city &/pr nearby places.
  4. The low cost of the car allows it to be considered a more economic and more efficient alternative to compact diesel cars which also leads to lesser air pollution within cities.
  5. To make the car's manufacture more geared towards developing economies, advanced hardware for technologies like "Autopilot", etc are left out which make this car simpler, cheaper, lighter and easier to manufacture.
  6. The Tesla app in the user's phone is used, and the phone is docked in the dashboard as a substitute for the expensive Interactive digital display. This is done, as phones are predominantly used in developing economies and serve as a more portable and easy-to-use digital device for the less articulate masses. This reduces the final cost of the car.
  7. The battery pack forms the bottom of the vehicle between the axles, concentrating the mass between the axles.
  8. This distributes its mass equally on its axles and lowering its rotational inertia, allowing it to turn more quickly.
  9. Since the battery pack is the single most heavy component of the vehicle, the car has a very low center of gravity height, due to the location of the battery pack.
  10. This also helps in achieving a high lateral acceleration and an increased protection against rollover. 
  11. The placement of the battery pack increases the rigidity of the passenger compartment, improving the passive safety of the car.

Notes -

Techniques Used/Notes -


  1. Highly Tuned FF1 EcoBoost® "Baby" Engine (3 Years Consecutive International Engine of The Year 2012,2013,2014) with DOHC, Direct Injection (@ up to 200bar) and Variable Valve Timing.
  2. A cylinder head with an integrated and cooled exhaust manifold that lowers exhaust temperatures for optimizing the fuel-to-air ratio.
  3. An innovative flywheel and front pulley design deliver improved refinement compared with traditional three-cylinder engine designs. 
  4. Engine friction is reduced by specially coated pistons, low-tension piston rings, low-friction crank seals and a cam-belt-in-oil design. 
  5. A variable-displacement oil pump tailors lubrication to demand and optimizes oil pressure for improved fuel efficiency. 
  6. Max revs increased to 7,500rpm by removing the heavy dual-mass flywheel (fitted to improve refinement and reduce gear rattle) and replace it with a lightweight steel version. It was dry-sumped.
  7. The engine block is cast iron instead of aluminum for up to 50% faster warm-up, at the expense of additional weight.
  8. Due to natural vibrations of a 3-cylinder design, the flywheel as with any other engine of similar configuration has been weighted properly to ensure smooth running, without the use of energy sapping balance shafts.
  9. Multiple fuel injections (namely 3), occur in a single combustion cycle.
  10. The engine also features an internal timing belt, bathed in the engine oil, for long life and greater efficiency and reduced noise. 
  11. The exhaust manifold is cast into the cylinder head, reducing warm-up times and therefore further aiding efficiency. All this is packaged in an engine block the size of an A4 sheet of paper.
  12. This car is a Formula Ford racer converted for road use that includes the addition of registration plates, wheel covers, front and rear lights, revised wing mirrors, road-legal tires. and a horn.
