Shell Eco-marathon: Students with fuel-efficient cars all set to compete

13 Pakistani teams will be up against 137 others in Malaysia.

ISLAMABAD: There is excitement and fear on Haider Khan’s face as Shell Pakistan’s team inspects the fuel-efficient car he and friends from the University of Engineering and Technology (UET), Peshawar, have designed.

Khan and his seven team members - all of them final-year mechanical engineering students - make up one of the 13 student teams from eight Pakistani universities, which have registered to compete in the Shell Eco-marathon in Malaysia in July.

The Eco-marathon, an annual event which takes places in Asia, Americas and Europe separately, challenges students to build vehicles that can travel the farthest distance using the least amount of fuel. In other words, the car which travels the most number of kilometers per litre of fuel wins.

Pakistani students face numerous challenges in building the cars, but this July they will be competing against 137 other teams from 15 different Asian countries and they hope to leave Malaysia as winners.



On Saturday, five of the 13 Pakistani teams prepared for the event by participating in a launching ceremony at the College of Electrical & Mechanical Engineering (EME) in Rawalpindi. There, the cars performed laps and Shell experts tested the cars for the Shell Ec0-marathon’s safety guidelines so as to fix  any problems before the competition.

To Khan’s relief, his team’s car - a 184 kilogram, 78cc grey four-wheeler named “Octa Mechanica”, which does around 65 kilometres per litre (km/l) - passed most of the tests, with a few suggestions from the specialists.

“We learned twice as much by building this car than what we learnt from textbooks in four years of engineering school,” he said.

For their car, Khan’s team modified a 125 cc bike’s engine. They used an aerodynamic, fibre glass body to increase mileage and are also trying to attach an Electronic Fuel Injection (EFI) system for more improvements.

Khan said the inspiration to enter the competition - this is the first time two teams from UET Peshawar are competing - came after seeing other Pakistani teams participate.

The team from EME College has participated in the event for the past three years, each time improving their mileage and performing better in the Asian contest.

In order to increase the mileage, we have tried to reduce the car’s weight and to minimize friction losses, explained Muhammad Usman, a final-year mechanical engineering student from EME College.

Usman said that the EME’s latest car is built from light-weight Aluminium and they have reduced friction in the energy-to-tyre transmission by using unidirectional clutch bearings.



Like Khan’s team, the EME car falls under the “Urban concept” gasoline category, one of the two major categories for the Eco-marathon; the other being “prototype” cars. The urban concept cars have to be as close to commercially produced cars as possible while the prototype cars could be more futuristic: three-wheelers and comparatively smaller in size.

Usman, who is managing the 2013 EME college team, said the competition has become a college tradition now.

“The seniors train the juniors not only in technical expertise but also how to get sponsors to fund the work,” he said.

Sponsors are important as funding and resources are the two major hurdles faced by Pakistani students.

“There is not much awareness about such innovation in Pakistan and we were disappointed by the response from Pakistani companies when we went looking for sponsors,” Khan said. “At times, we had to put Rs70,000 each from our own pockets into the project.”

Even when the universities support testing and trials, the urban concept cars cost around Rs400,000 to Rs500,000; the prototypes half as much.

But on top of the research and development work, the teams have to bear airfare for students and freight charges for transporting the cars to Malaysia, Usman said. Adding that they were still looking for a sponsor to finance an even lighter carbon fibre exterior for their car.

On Saturday, Shell Pakistan subsidized some of these costs by awarding six cash prizes to the teams worth Rs 0.9 million altogether - Khan’s team and Usman’s team won separate awards worth Rs200,000 each for most innovative car and best mileage respectively.

Shell Pakistan Managing Director, Omar Sheikh, said that in addition to bringing recognition for Pakistan on the world stage, the competition also has some direct benefits.

“Such events encourage young enterprising individuals and are also a way for Shell Pakistan to foster innovation in the area of energy,” said Sheikh.
