Gordon Murray, the ace automobile designer and his team Gordon Murray Design introduced a frugal T.25 car back in 2010. The car was designed to solve the urban transportation problem and used a prototype oil developed by Shell Lubricants to boost the mileage. Years later, Shell has done a "total rethink" of the T.25 concept by taking the frugality to a completely new level.
The Shell concept city car uses half of the energy needed to build and run a normal city car and has a similar size, giving it a staggering mileage figure of 38kmpl. The three seater car is made as an example of energy efficiency improvements and shows how less materials can improve road transport sector. Interestingly, Shell aims that showing that how lubricants can be an integral part of vehicle manufacturing and how modern technology can use the process of "co-engineering" to develop body and design with lubricants.
Various studies done (all independent) has shown how Shell's concept car can reduce 34% of the primary energy of its complete lifecycle as compared to a typical car in the UK. If the Shell concept car goes into production, it will use half the energy required to build and run a typical hatchback in the UK and 69% less than that of an SUV available in the UK.
The concept is co-engineered by some of the world’s leading vehicle, engine and lubricant designers. The car takes a holistic view of energy reduction starting from the design material selection, aggressive downsizing and streamlining the body. That, along with the increase in efficiency through innovative engine design and lubricant formulation impacts the overall minimization of energy lifecylce.
Each of the three elements of the vehicle work optimally with each other to produce one immensely efficient car. The car’s fuel consumption has been carefully monitored using a range of vehicle testing protocols including both steady state and urban driving styles. The test results indicated a consumption of 2.64litres per 100km (38km/litre) at 70kmph with an improvement of 4.67g CO2/km, a 5% improvement from the use of standard lubricant.
The bespoke lubricant is provided by Shell for all the fluids for the car, especially the motor oil to complement and enhance the overall efficiency. While the special lubricant based on premium product Shell Helix Ultra with PurePlus Technology aimed at minimizing the friction. Engine guru Osamu Goto’s optimized the 3-cylinder petrol engine to reduce the friction too.
Goto re-designing and optimized many internal engine components and reduced CO2 emissions by 7.1% as compared to standard lubricants, highlighting the value of co-designing engine and fluids. As for the base car, the Shell Concept Car is thought-over version of the Gordon Murray Design T.25 city car which was introduced in 2010. Shell produced a prototype oil for T.25 to improve its energy efficiency.
The new car uses Gordon Murray Design’s patented iStream platform and weighs just 550kg. Carefully built using materials with low energy and CO2 footprint, the car uses a number of 3D printed components to accelerate the construction of the vehicle. Intensive use of recycled carbon fibre helps the assembly of the car in a quarter of the price of a conventional steel car.
