IP67 is a cable and enclosure spec, not a total system spec. While it will help with connectors, the control systems themselves are still industry standard manufacturing. Let's not overstate the effects of IP67.
Are u familiar with the control systems they are using?
"14 Updatable modules with SOTA"
"new Defender also employs advanced consumer technology including high performance Snapdragon processors and advanced QNX operating systems to deliver its connected features"
"The new Land Rover Electrical Vehicle Architecture (EVA 2.0), forward-facing digital camera, advanced ultrasonic sensors and powerful 3Gbit/s onboard network support a comprehensive suite of driver assistance technologies, with the cameras and sensors governed by a single integrated processor, or domain controller."
"To ensure the electrical systems are as rugged and robust as the rest of the vehicle, the Defender is the first new Land Rover vehicle to benefit from enhanced validation testing, the result of a $45m (£37m) investment in new facilities and infrastructure."
Hardly industry standard.
Most dodgy electrics come from environmental impacts, heat, dust, water ingress, dodgy connections.
IP67 is a huge thing towards electrical reliability and something I've not heard of before in a civilian 4x4.
Lets not understate it either
"The electronics and connections in the new Defender have been designed to meet the IP67 water immersion standards. That means they can be submerged in one metre of fresh water for an hour without intrusion or damage."
