Making performance versions of performance cars somehow seems like a needless operation, but the likes of the Ferrari Speciale, the Porsche GT3 RS, or the Lamborghini Performante showed there is a market for these types of performance cars. Within the McLaren macrocosmos, we have the so-called LT line up. It is still a small lineup, but with the recent introduction of the fascinating, 600LT, the LT offering now includes the 675LT, the 675LT Spider, and the 600LT. However, there was a fourth LT car. The one that all modern McLaren LT performance beasts take a bow to. Their grandfather, if you like - the McLaren F1 GTR Longtail.
