Structural optimization principles for edge AI in motorsport telemetry

In motorcycle motorsport, engineering decisions are constrained by mass, stiffness, fatigue life, and thermal margins. In a comparable way, deploying large language models (LLMs) for edge or trackside assistance is limited by memory capacity, bandwidth, latency, and power. This paper presents a systems-engineering framework that relates structural lightweighting and post-training quantization (PTQ) through second-order sensitivity. In mechanics, safe material removal is governed by the stiffness matrix [Formula: see text]; in neural networks, safe precision reduction is governed by curvature information encoded in the loss Hessian [Formula: see text]. To ground this analogy, we combine a structural case study based on topology optimization of a Formula Student upright with an edge-oriented evaluation of low-precision LLM deployment using established PTQ pipelines (GPTQ and AWQ). The structural example illustrates how sensitivity-guided material removal preserves load paths and mechanical integrity, while the LLM study examines how sensitivity-aware quantization can reduce computational footprint while maintaining operational usefulness in telemetry-related inference. To assess deployment feasibility, we define two practical metrics: a Digital Factor of Safety ([Formula: see text]), based on a perplexity-derived integrity threshold, and Intelligence-per-Watt (IPW), which captures energy-aware inference efficiency. For a 32B-class operating point, INT4 weight-only deployment reduces memory footprint from 61 GB to 18 GB, improves throughput from 26.0 to 69.9 tok/s, and lowers measured power from 295 W to 165 W while remaining within the proposed integrity envelope. The contribution is methodological rather than algorithmic: we do not introduce a new quantization method, but a reproducible framework for analyzing when low-precision LLM deployment becomes feasible under motorsport-inspired resource constraints. The results support the practical relevance of stiffness-informed digital lightweighting, while also highlighting that the evidence is limited to the structural and computational case studies considered here.

Abstract

In motorcycle motorsport, engineering decisions are constrained by mass, stiffness, fatigue life, and thermal margins. In a comparable way, deploying large language models (LLMs) for edge or trackside assistance is limited by memory capacity, bandwidth, latency, and power. This paper presents a systems-engineering framework that relates structural lightweighting and post-training quantization (PTQ) through second-order sensitivity. In mechanics, safe material removal is governed by the stiffness matrix [Formula: see text]; in neural networks, safe precision reduction is governed by curvature information encoded in the loss Hessian [Formula: see text]. To ground this analogy, we combine a structural case study based on topology optimization of a Formula Student upright with an edge-oriented evaluation of low-precision LLM deployment using established PTQ pipelines (GPTQ and AWQ). The structural example illustrates how sensitivity-guided material removal preserves load paths and mechanical integrity, while the LLM study examines how sensitivity-aware quantization can reduce computational footprint while maintaining operational usefulness in telemetry-related inference. To assess deployment feasibility, we define two practical metrics: a Digital Factor of Safety ([Formula: see text]), based on a perplexity-derived integrity threshold, and Intelligence-per-Watt (IPW), which captures energy-aware inference efficiency. For a 32B-class operating point, INT4 weight-only deployment reduces memory footprint from 61 GB to 18 GB, improves throughput from 26.0 to 69.9 tok/s, and lowers measured power from 295 W to 165 W while remaining within the proposed integrity envelope. The contribution is methodological rather than algorithmic: we do not introduce a new quantization method, but a reproducible framework for analyzing when low-precision LLM deployment becomes feasible under motorsport-inspired resource constraints. The results support the practical relevance of stiffness-informed digital lightweighting, while also highlighting that the evidence is limited to the structural and computational case studies considered here.
