  We present a successful deployment of high-fidelity Large-Eddy Simulation
(LES) technologies based on spectral/hp element methods to industrial flow
problems, which are characterized by high Reynolds numbers and complex
geometries. In particular, we describe the numerical methods, software
development and steps that were required to perform the implicit LES of a real
automotive car, namely the Elemental Rp1 model. To the best of the authors'
knowledge, this simulation represents the first fifth-order accurate transient
LES of an entire real car geometry. Moreover, this constitutes a key milestone
towards considerably expanding the computational design envelope currently
allowed in industry, where steady-state modelling remains the standard. To this
end, a number of novel developments had to be made in order to overcome
obstacles in mesh generation and solver technology to achieve this simulation,
which we detail in this paper. The main objective is to present to the
industrial and applied mathematics community, a viable pathway to translate
academic developments into industrial tools, that can substantially advance the
analysis and design capabilities of high-end engineering stakeholders. The
novel developments and results were achieved using the academic-driven
open-source framework Nektar++.
