Developing and validating full scale vehicle aerodynamic performance including, but not limited to measures such as lift, downforce, drag and aerodynamic balance. Full scale testing under fully controlled ambient conditions ensure accurate, representative and repeatable tests.
Evaluating vehicle performance such as speed, acceleration, braking and ride height comfort. The tunnel is not affected by the weather so is available all year round.
Assessing thermal and cooling performance of engine bay, radiator, powertrain and brake components. Testing and validating thermal counter measures. Evaluating heat soak issues.
Acoustic testing for passenger comfort and conformity to government legislation. Examples include the evaluation of cabin noise, engine sound levels, exhaust systems or even fitment of structures and assemblies.
One specific aerodynamic test Catesby Tunnel is perfectly set up to accommodate is a coastdown. The length of the tunnel means there is ample time to accelerate a vehicle up to typical speeds of 130-180kph before putting it into neutral and allowing speed to decay. The combination of constant environmental conditions and an incredibly smooth asphalt surface makes repeatability in the tunnel outstanding. This means tiny changes, such as placing a small camera mount to a vehicle can be easily spotted in the data.
Catesby Tunnel will obtain VCA certification of the facility for WLTP coast down in early 2023.
Determining noise source, measuring noise levels and analysing sound propagation as a consequence of turbulent airflows.
Representative vehicle emissions testing of carbon dioxide and pollutants such as carbon monoxide, hydrocarbons and oxides of nitrogen.
Practical testing of complex vehicle contamination processes due to adverse environmental conditions.
