We're often told by motorsport engineering types that technology developed on racing cars will eventually filter through to road-going vehicles.
These days though it's hard to see where. If anything, race cars seem to be adopting road car technology - like hybrid systems - in an effort to make the sport greener in a world increasingly worried about climate change.
Every other recent road car development seems to have come from within the road car industry. Automatic parking systems certainly weren't developed to make F1 cars quicker, and we doubt cylinder deactivation came from NASCAR. Then there's blind spot detection, adaptive headlights, stop-start systems... none of which you'll find on the average British Touring Car.
Nissan though is thinking outside of the box. And inside a triangle.
What you see here is the BladeGlider concept, and if you're familiar with your motorsports you'll recognise the shape immediately from a brace of rather unusual race cars.
Unsurprisingly, the BladeGlider is the brainchild of the same man who conceptualised those two racers - Nissan Motorsport Innovation director Ben Bowlby. And aside from the conversation-starting looks, the delta-wing design has some surprising benefits for both race cars and road cars.
The narrow one-metre front track and wide rear have several effects on the way the car corners. It's very manoeuvrable, but also highly stable with 70 percent of the car's weight on the rear wheels. It's not a pendulous Porsche 911-style weight either, because despite appearances those small front wheels do an equal amount of the work.
Nobody can really explain that better than Ben Bowlby himself, so here he is explaining just how the Deltawing race car deals with the same unusual setup - skip to around 8:00 for the full story.
Impressive, no? It gets better - the shape is also great for aerodynamics (it has a very small frontal area compared to most cars), while Nissan says the unusual cockpit design means almost unparallelled visibility too.
The engineering doesn't stop there. Like the ZEOD RC race car, BladeGlider is an electric vehicle. In fact, it's more of an electric vehicle because it isn't expected to last for a full 24 hour Le Mans race, so doesn't need a petrol engine to prop up the batteries.
Nissan doesn't go into specifics but says a production BladeGlider - if and when one appears - would use in-wheel electric motors rather than a central motor and a pair of driveshafts.
The battery is a little more conventional, hailing from the Nissan Leaf - but like everything else in the car, it's positioned further back to optimise weight distribution. Your passengers will add to that by sitting either side and to the rear of the driver, echoing the car's shape.
It's almost too much to take in, in one sitting. Individual aspects of these features would be innovative enough, but Nissan appears to have taken the sports car rulebook and fed it to the dog.
There's absolutely no guarantee a car like this will appear on our roads in the near future... but you won't hear us complaining if it did.
