My attempt at doing one on Pagani's behalf

There's no wheels as of yet because I'm trying to think up a design, besides I'm awful at drawing them anyway

.
Based on the Pagani Huayra, this is the Huayra Vision GT. Just like the original Huayra, the Vision GT uses AMG's twin turbocharged V12 engine, but it has been subtly modified producing 730 brake horse power, 10 more than in the standard car. This allows it to achieve a 0-60 time of 2.4 seconds and a top speed of 225 mph.
However, unlike the original Huayra this version uses a double clutch system as opposed to the single clutch offering, allowing for smoother and quicker gear changes when accelerating at breakneck speeds. The standard version used a single clutch system to save weight, rendering the use of a much heavier double clutch transmission slower, but by saving every gram we can on the body, lack of paint and the interior, we have achieved a classified yet lower weight prior to fitting a second clutch. The result is a 0.5 second faster 0-100 time than the original Huayra, making this car one of the fastest accelerating road-legal cars on the planet.
The body itself has also undergone some changes, such as lowering the nose of the car, making the bonnet several degrees steeper proving more front end grip when cornering at speeds of over 100 mph. The headlights have also undergone a slight change, purely to distinguish the car from the original version. Part of the weight saving process was to remove the dynamic flaps from the front end, which have been replaced by air intakes which direct cool air towards the front brake discs, lowering the temperature of them after decelerating from 150-0 in less than 6 seconds.
The rear dynamic flaps remain though, however they too have undergone some changes. They sit at a slightly steeper angle when accelerating, ensuring as much tyre/road contact is produced contributing to the savage 0-100 time. The flaps have also been made larger providing more wind resistance when bringing the car to a stop, and more downforce when driving this car up Eau Rouge.
A car this powerful produces a massive amount of heat, which is why every vent on the side of the Huayra has been drastically increased in size. In addition to this, a roof scoop has also been added to the car to help lower those high temperatures.
