Zonal architecture replaces a kilometer of wiring with a lot more code Does constant engine starting and stopping shorten a hybrid engine's life? Cell-to-pack and structural batteries: what happens to them in a crash? Steer-by-wire deletes the steering column — what happens if the motor fails? Why car brakes fade on a long mountain descent but never in city driving Why do power-split hybrids get better city mileage than highway mileage? Series hybrids in city buses: how does the duty cycle change the design? Series vs parallel hybrids: which layout wastes less energy at highway speed? Which compute platform runs a full perception stack under 100 watts? Gigacasting saves weight but turns a fender bender into a write-off Plug-in hybrid battery sizing: why do some PHEVs only manage 20 electric miles? Carbon fiber is strong and light: why is it still not in cheap cars? Do roof-mounted lidar units survive years of vibration and road salt? Why steering feel has gotten worse on electric power steering cars Why the paint shop is the dirtiest part of building a car What is a Miller cycle engine and why do hybrids rely on it? Turbo downsizing vs a bigger naturally aspirated engine: which sips less? How much of a new car's development is simulation rather than real prototypes? Are brake dust and tire particles counted as vehicle emissions now? Magnesium car wheels and engine parts: great on paper and rare in practice 48V electrical systems: which features would not exist without them? Software defined vehicles: can a maker change how my car drives with an update? Why do hybrids need a separate cooling loop for the inverter and battery? How engineers balance ride comfort against body roll in a family sedan Do hybrid systems recover energy while coasting or only under braking? Do the digital cluster and the head unit share one computer? Why do premium interiors still creak when the temperature drops? What a car maker learns from mule test vehicles before the body exists How much water it takes to build one vehicle and where it goes One platform serving three body styles and four brands: what the design team gives up Why tall SUVs feel tippy in an emergency lane change How adaptive high beams dim around oncoming traffic without the driver touching anything
