Have you ever heard of a Lichtkanal? No, me neither, until earlier this week when Audi shipped us down to its Ingolstadt HQ in southern Germany.

It turns out that the company’s new ‘light canal’ is a 120m-long tunnel, which is used to test new types of lighting technology and ‘camera-based lighting assistance systems’. Audi claims the tunnel is the ‘longest driveable lighting tunnel in Europe.’

The new tunnel – which goes into full operation this March – is part of a bigger department at the Ingolstadt engineering centre, which Audi calls the Lighting Assistance Centre.

The German company is taking innovation in lighting technology very seriously. It says that cutting-edge lighting technology and design is an important part of the brand’s future. Not just for "active safety" but also for "design differentiation" and "making technology visible".
