Self-driving cars will carry a premium of at least £10,000 when they are introduced around 2021, thanks to the suite of high-powered computers and sensors that will be needed to make them safe at any speed.
Up to nine cameras, nine radars and a laser-scanning lidar system will be standard equipment, feeding data to up to five high-powered processing computers — all of which will add significant cost.
“There will be very powerful computing power in a self-driving car,” revealed Eric Coelingh, Volvo’s head of autonomous driving, speaking at a conference in London to discuss the future of self-driving cars. “We are talking processors measured in gigabytes, rather than the kilobytes we have now. The price will depend on volume, but we are talking expensive componentry that could easily be £10,000.”
Volvo’s design for a self-driving car also features the so-called ‘redundancy’ of safety-critical parts. The idea, which was developed in the aerospace industry to improve air safety, will also add cost. A self-driving Volvo will, for example, feature two antilock braking pumps and two electrical steering systems, one of each reserved as a back-up to be used if a main unit fails.
