Théophile Allard, CTO and co-founder at Neural Concept The automotive industry is undergoing a structural shift. Development cycles compress from years to months, regulatory requirements multiply and customer expectations rise. The automotive industry’s structural challenges feel more burning than ever: deliver better vehicles, faster, without sacrificing quality or cost.

Goeff Lewis, Technical Director, Duvelco OEMs love SiC and GaN [1]; higher switching speeds lead to more efficient motors, which in turn mean greater range or lighter, less expensive batteries for the same BEV range. Higher switching speeds, dV/dt, can mean increased displacement current coupled onto the motor shaft [2].

Why Vehicle Motion Control matters for the powertrain Vehicle Motion Control (VMC) is shifting from a chassis-led specialist topic to a decisive development discipline for electrified drivetrains. As electrification and rising computing capability reshape vehicle architectures, motion can no longer be treated as the sum of separate domains. For powertrain engineers, that means traction, stability…
