Trioba 2+1

Last updated

The Trioba 2+1 is a high performance electric sports car for the year 2020 mainly for the right hand drive market (UK, India and others) conceptualized by the Indian car designer Shashwath Bolar. It derives its inspiration from organic and asymmetrical forms in nature, fashion and sculpture. The Trioba 2+1 concept won the 3rd place in the “Stile Italiano Giovani 2008” International Car Design Exhibition at Turin, Italy. The exhibition was also part of the World Design Capital – Torino 2008.

Electric car automobile propelled by an electric motor

An electric car is a plug-in electric automobile that is propelled by one or more electric motors, using energy typically stored in rechargeable batteries.

United Kingdom Country in Europe

The United Kingdom, officially the United Kingdom of Great Britain and Northern Ireland but more commonly known as the UK or Britain, is a sovereign country lying off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state‍—‌the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of 242,500 square kilometres (93,600 sq mi), the United Kingdom is the 78th-largest sovereign state in the world. It is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017.

India Country in South Asia

India, also known as the Republic of India, is a country in South Asia. It is the seventh largest country by area and with more than 1.3 billion people, it is the second most populous country as well as the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives, while its Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.

Interior space

The interior space is based on enhancing social interaction and focuses mainly on the third seat. From Shashwath’s MA Automotive Design (Coventry University, 2006 - 2007) research and three seat user tests, it has been found that the following parameters affect social interaction directly and indirectly and these have been considered while designing the interiors:

Exterior

Once the seating layout was established the exterior was designed around it, hence designing inside out. The form is largely symmetrical and asymmetry is introduced in such a way that it does not hamper aerodynamic efficiency. The features include asymmetric body panels and bonnet, which creates interesting, highlights and provides space for boot and a spare wheel. The non – driver side has an asymmetrical gull-wing door, which provides easier ingress and egress for occupants.

Aerodynamics branch of dynamics concerned with studying the motion of air

Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is the study of motion of air, particularly as interaction with a solid object, such as an airplane wing. It is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these fields. The term aerodynamics is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for the development of heavier-than-air flight and a number of other technologies. Recent work in aerodynamics has focused on issues related to compressible flow, turbulence, and boundary layers and has become increasingly computational in nature.

Power

This rear driven concept has modulated Li-ion batteries, which gives the freedom to use space behind the third seat in such a way that optimizes seating space within. The Power Control Unit (PCU) provides sufficient power to the rear wheels through the Rear battery (Power = 250KW) and transmission unit. Air-intakes are provided to cool the Li-ion batteries and large vents are provided at the rear for dissipating heat from batteries.

Lithium-ion battery rechargeable battery type

A lithium-ion battery or Li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery.

3-seat concept

Since 2000 there have been many 3 seat / 2+1 concepts launched by almost all big OEMs (Original Equipment Manufacturers) in various motor shows around the world like the Jeep Treo, Renault Zoe, Wind, Nissan Urge, Pivot, Volvo 3CC Ford Reflex, etc. This clearly shows an upward trend for this new segment of cars.

Moreover research shows that one-child family is a growing trend all over the world and also the average occupancy in cars has gone down (The avg. occupancy per car in UK has gone down from 1.64 to 1.59 between 1985/86 and 2002/03). [1] Looking at the rate at which our natural resources are getting depleted, it is ironical to build cars that over satiate our demands rather than meet our needs. This clearly shows the huge potential for the 3 seat cars in the near future.

Development

Once final sketches, renderings and package drawing was done a quarter scale clay model was done in 6 weeks. Later a mould was taken and an FRP model was created out of the mould. Further sanding, hand polishing, painting and finishing was made on the FRP model to arrive at the final model.
