The RS carbon fibre side splitters work in a similar way to the RS front splitter in that they separate airflow most importantly when the car is in yaw with medium and high speed cornering, this in turn will increase downforce on loaded tyres and prevent air rolling underneath the side pod and creating lift.įront and rear wheel arch vents (available in body coloured gel coat or an exposed carbon fibre finish) generate downforce and reduce drag. If air passes too fast through the radiator core you generate a boundary layer so the heat from the radiator cannot attach itself to air passing through. This also helps with an additional small amount of downforce on the front axle while maintaining low co-efficient of drag. To control airflow at high velocity the entry into the radiator will generate a stagnation zone between high pressure and low pressure this backs up in front of the radiator as speed increases and will bleed off through new slots in the front body stiffener moulding and exit on the top surface of the front body. We designed an integral S Duct system for the front canopy. Now that the radiator has a totally uninterrupted flow of air it has improved cooling efficiency. At the same time it controls air flow over the leading edge and maintains a boundary layer over most surfaces. The re-design of the front body has reduced the frontal area to a minimum and also adds a lower co-efficient of drag. The only downside with using dive planes is that they will increase the co-efficient of drag. The carbon fibre front dive planes can be used to move the aero centre of pressure further forward and produce more downforce on the front axle.

The integral vortex generators on the outside points help to control wake around turbulent air from the front wheels, at the same time giving smooth flow to the underside of front dive planes (if fitted). The optional carbon fibre version also incorporates diffuser ramps to the underside to increase downforce while minimising the co-efficient of drag. The front splitter has been engineered to mount directly to the chassis, thereby removing any flexibility and putting loads direct into the chassis. Minimum co-efficient of drag achieved in the MIRA wind tunnel was 0.304 with the ability to adjust downforce to a maximum of over 1000kgs. The design brief for the Ultima RS aerodynamics was to improve high speed stability whilst reducing the co-efficient of drag to achieve a more aerodynamically efficient car, resulting in market leading levels of downforce. The result is truly remarkable – a car that is devoid of restraint and an improvement in almost every area. The RS is a real milestone in our company's development. The Ultima RS model is the most thorough and complete overhaul of the road legal Ultima ever to be released, with thousands of enhancement changes to specification.

Performance aside, the Ultima RS is a vastly improved and modernised supercar, with even greater levels of style, fit, finish, quality, safety, driver comfort, sophistication, usability, practicality and handling finesse. Every design facet of the restyled Ultima RS panels results in an increase in performance envelope capability compared to previous generation Ultima models. The new RS has market-leading levels of downforce via revised aero systems, perfected in the MIRA wind tunnel. With three decades of highly successful sales and performance accomplishments with our previous models, it was time to put everything we have learnt into the new Ultima RS flagship model.
