McLaren has just released a promotional clip for the 675LT to celebrate the start of production and although their most powerful model of the Super Series has already sold out, nothing has stopped them from making a 4K video of beast going around Castelloli track in Spain. Compared to the previous series-topper, the 650S Coupe, the 675LT is 100 kg lighter and 24 HP and 22 Nm more powerful as McLaren’s engineers fiddled around with the V8 3.8-liter twin-turbo engine and squeezed 666 HP (496 kW) and 700 Nm.
