Team Profile
The 2012 competition marks the 4th Class 1 entry for Team SURTES.
This year, we focused on the refinement of the vehicle concept of our previous racing car through extensive research, design and testing. Hence, our main design objectives were on the optimisation of the technical solutions that we have developed over the last couple of years. We focused on improving the reliability and durability of all components without compromising their performance.
Through extensive use of lightweight, high strength materials such as carbon fibre, aluminium and titanium alloys, our 2012 car weighs less than 200kg. The chassis is a new and improved iteration of the hybrid chassis solution developed last year. It comprises a carbon fibre monocoque front and a tubular steel space-frame rear with enhanced reliability, maintainability and accessibility.
Power is provided by a 2009 Honda CBR600 RR engine, which has been chosen for its smooth wide-band torque characteristics. It is fitted with newly designed custom intake and exhaust systems, a bespoke carbon fibre dry sump lubrication system and a fully tuneable ViPEC V88 ECU.
To understand and enhance the dynamic behaviour of our racing car, we have developed and fitted advanced electronic systems for data acquisition and telemetry.
The car has been set up as a pure driver’s car with no electronic aids such as launch control or traction control, thus improving the visceral driving experience.
Extensive data acquisition has been carried out to optimise the vehicle suspension and the car’s handling to be bespoke for each of our drivers.
