As for the 675LT, it will be the lightest, quickest and most-focused member of the Super Series. It will come in coupe form only and feature a number of enhancements aimed at improving aerodynamics and creating more downforce at speed. One of these enhancements, of course, will be extended tail section, which we hear will look substantially different to the design used on other Super Series variants. The 675LT is also tipped to be around 220 pounds lighter than the 650S, which weighs just under 3,000 pounds dry.

Peak output will be a hellish 666 horsepower using American units for power, with drive going to the rear wheels via a seven-speed dual-clutch transmission.
