Twenty-five years of automotive compute, driven rather than read. Each safe lane change moves the platform up a level of complexity, from one ECU per function toward the compute for the entire vehicle.
One function, one box. Infotainment, cluster, and rear-seat each ran on their own compute, wired to their own screens.
Lane 01 · MULTIMEDIA PLAYBACK
2001-2013 · Mistral / Harman
The first center display plays media from every source of the era: CD, Made for iPhone / iPod, hands-free calling, and media streamed from the phone. All on a single compute box.
What this lane change brought
ImpactConsumer media made production-real inside the car, one function on one ECU.
Lane 02 · PREMIUM INFOTAINMENT
2013-2016 · Harman / JLR
Navigation and infotainment come together for the driver and every passenger, front and rear. Two separate boxes: one drives the front dual display, the other drives rear-seat entertainment.
What this lane change brought
ImpactEvery occupant, front and rear, gets navigation and infotainment, across two separate boxes.
Lane 03 · WORKLOAD CONSOLIDATION
2019-2020 · Intel · Chery, Hongqi
A single SoC drives infotainment for all passengers and the driver cluster together, safely partitioned for mixed-criticality with ACRN. Fewer boxes, less wiring, lower cost.
What this lane change brought
ImpactFewer boxes, less wiring, lower cost: one SoC runs the cluster and cabin infotainment side by side.
Lane 04 · SOFTWARE-DEFINED VEHICLE
Q4 2025-present · Jaguar Land Rover
Two high-performance compute boxes and two zonal boxes run the entire vehicle: IVI, ADAS, and all vehicle functionality. Zonal boxes drive no screens, they manage the sensor and actuator nodes.
What this lane change brought
ImpactFrom one ECU per function to a couple of HPCs and zonal boxes running the entire vehicle.
