Thats about as likely as one of auto express's exclusives. Looks more like a one off pimp my ride style aygo and a big pinch of salt. Its probably running a standard aygo engine, but with uprated elements ro acheive a 7.5 0-60 and 127 top speed.
If Toyota themselves were to make an uprated Aygo, surely it would use an engine from one of their existing cars. The celicaVVT 190 lump perhaps.
Plus I'd imagine the first publicly available shots wouldn't be from a window looking into the company carpark in the UK.
