In fact, the Japanese automaker claims that half of all hybrids sold are Toyotas. But it didn’t get there by resting on its proverbial laurels, and it isn’t going to maintain (let alone increase) its market share by doing so, either. That’s where the concept car you see here comes in. Taking position as something of a Prius of the future, the NS4 concept cuts a striking profile – certainly more striking than the current kamm-tailed Prius. But even though the technologies it encompasses are targeted to reach the market by around 2015, the show-car details – like that eminently dentable front beak -probably won’t. While Toyota works on all manner of electric and fuel cell powertrains, the NS4 packs a similar plug-in hybrid system as the current Prius PHEV. But the show car encompasses a slew of other technologies, like a smartphone-like interface to monitor and control everything from the air conditioning to the battery charge. Toyota has also packed the NS4 with its latest pre-collision and blind-spot monitoring systems, adaptive headlights and four new types of glass – the one part of the car we probably take most for granted. Of course, this being a concept car, Toyota has also replaced the side mirrors with an around-view camera system, but laws being what they are for now, don’t expect to see that in showrooms just yet.
