Bioframe concept is my proposal for the Local Motors and Arpa-E contest 2015, whose requirements is to create a purely conceptual, novel lightweight vehicle using advanced materials and innovative structural solutions while maintaining/exceeding current vehicle safety standards, in addittion to 5 seater sedan distribution, and current engine/drivetrain. 

This concept is inspired by the internal human bone tissue structure, ellipsoid shaped (very aerodynamic and structurally more stable than a box shaped conventional spaceframes), and biomorphic design.

Aerodynamics has been improved. The shape of the frame permits much better airflow through all the car body. The top of the vehicle is soft and rounded, without hard changes in the curvature like a conventional car, and the down sides permit to channel the air coming from the radiators, by de sides, then through the rear suspension, exiting by the center of the low pressure behind the car.

The weight of this vehicle is 781 kg  (44% weight reduction over a current sedan with similar size which weights 1400 kg). This is possible by using a new reinforced Aluminum matrix composite bodyshell, innovative architecture, and graphene components.

SEAT MLX 2100-Maglev personal vehicle

SEAT MLX 2100 - Maglev personal vehicle

Year 2100. If the current progression is maintained, the estimated number of cars in the world will be more than 10000 milions. Huge cities, constant colapses, even the air traffic density becomes dangerous.
To solve this hipothetical future chaos, arise the idea of magnetic levitation personal vehicles: the SEAT M.L.X. (Magnetic Levitation Xshape). 
This was one of the projects during my internship at SEAT, the second semester of 2014.

With the apropiate road distribution, optimization, and suitable infrastructure of magnetic ground, this vehicle is able to travel at speeds of 600+ km/h, thus lighten the extreme traffic density in the cities, and interurban displacements, reducing or eliminating the need of traveling by plane.

The SEAT MLX is a 4 seater maglev vehicle, equivalent to a current family sedan, for the year 2100. Its shape is created mainly following the aerodynamical function, vital, due to its high speeds, besides very tensional surfaces, with its reinterpreted characterstic SEAT double blisters in the sides, agility feeling, sharp lines and aeronautic influence. 

The body is a monocoque structure, combination of advanced composite materials and ultraresistent and light polymers.

Its two main systems are: the magnetic levitation system, composed by two big rotary electroamgnets, with which is achieved the ability of hovering above the magnetic road with great stability due to the gyroscope effect, and the other is the propulsion system, formed by four hybrid microturbines.

The engines of the propulsion system are a combination of ultra efficient micro turbines running on biodiesel, with a powerful electric motors with multiplier transmision to move the turbines at adecuate speeds.

Electric charge is stored in ultra light and efficient bateries and super capacitors based on carbon nanotubes, extremely optimized in the year 2100. Those are located longitudinally between the seats, in the place of a current car driveshaft. Charge process is achived by plugin the batteries and regenerative braking (the air pressure at high speeds move the turbines with power enoug to roate the electric engines acting as generators).

The MLX is able to change its direction and trajectory using two elements: the four stabilizers located in the ends of the vehicle like the wheel arches of a conventional car, mainly for high speed directional stability control, and the four hybrid engines located in the place of the wheels of a current car, which aren´t parelel. The front engines are slightly convergent respect the direction of travel, and the rear engines divergent. This is so to help turning while hovering at low speeds, accelerating the left engines to tur right, and vice versa.

Other interesting elements of the SEAT MLX are the laser headlights and rear lamps integrated in the stabilizers, and double sidded mirror material in the rear doors.

SEAT Roadster


This Roadster concept is one of my personal projects during my stay at SEAT as intern (second half 2014).

It´s the result of my research, as to how to fill the gap in the VW group range in this kind of vehicle. With its sporting appearance, high performance, 2 seater, lightweight, rear wheel drive, this is the perfect competitor against the new mazda mx-5.

The SEAT Roadster has been designed with character and fun to drive in mind; it´s based on very dynamic shapes, geometric sculptures, and very tense lines. It has a windshield that flows from the bonnet, which doesn´t have A pilars due to the stiffness of the frame and roll over bars. Its short overhangs contributes to the good handling and maintain the size as compact as possible.

On the sides we can find its muscular shoulders, followed by the carbon panels that cover the engine cooling exits. The body is aerodynamically efficient, with low drag and remarkable downforce, due to the shape of the top border of the windshield, directing the air flow towards the roll over structure and transversal wing on the rear, achieving a continuous air flow with minimum turbulences over the top an rear of the car, and the front and rear integrated wings in the bottom of the body, in adittion to the venturi-effect underbody and rear difusser.

In the front side, predominates the carbon fiber panel which gives its powerfull personality, and the angular headlights,similar to the rearlights, which visualy connects with the shoulder line and converge towards the rear emblem.

With minimal modifications, we have the cup version, a true racing machine, for trackdays and One-Make series Championships.

Technical info: Hybrid powertrain, 1.4 tsi engine (same as ibiza cupra block) more tan 200 hp and electric, total combined output>240 hp; weight < 960 kg (2130 lbs), Weight distribution Front/Rear: 50/50. Power to weight ratio=4 kg/ hp, better than mazda mx5, similar to: Nissan 370z, Porsche 911 careara, Jaguar F-type S v6.

Railgun Rifle Concept


New Electromagnetic railgun rifle concept (electrically powered electromagnetic projectile launcher). Powerfull as the current huge railguns, but light and compact as a bullpup assault rifle. The massive electrical power required is supplied by an atomic battery. Heat dissipation issues are solved using a water cooling system, bosted by several fans. Muzzle velocity> 2000 m/s. Rate of fire> 1700rpm
