![]() ![]() The car sported a wing at the back that added downforce to the vehicle at higher speeds. It was extended to the rear by a sloped windscreen mounted on the tailgate. Since Mercedes-AMG built the GT Coupe as a grand tourer, it carefully crafted the greenhouse with a raked windshield followed by an arched roofline with an option for a panoramic glass roof. The hood boasted two power domes that reflected the V-shaped engine underneath it. On the flared front fenders, behind the wheels, the car manufacturer installed extracting vents. In addition, they created an air curtain that lowered the drag resistance. It was flanked by functional side scoops that channeled the air from the front of the vehicle to the front discs to cool them. At the front, the car featured the Panamericana grille specific for vehicles built in Affalterbach. The 2024 GT Coupe shared its underpinnings with the 2024 Mercedes-Benz SL, but everything else was different. But after nine years and around 18,900 units sold, the model needed a much-deserved retirement paving the way for the new generation, the C192. The automaker introduced this nameplate in 2014 and kept it alive until 2023. Still.In the summer of 2023, Mercedes-AMG launched the second generation of one of the most famous products, the GT Coupe. L/D 0.3 is 1 unit lift for every 3.33 unit drag, not 3. SCC got its numbers wrong, or there was miscommunication somewhere between Nissan, its engineers, its engineering spokesperson, and SCC.Įrror earlier. what other streetable car can do that? It kills everything by miles including just about every supercar, should have had many articles written specifically about its revolutionary aerodynamics, and will soon be copied by other manufacturers. If you put this car with SCC's numbers into overall production and race context, it is superior to almost anything out there. The SCC numbers don't match Nissan's aero chart. It's just highly improbable to this degree, without heavy ground effect and aggressive underbody tunnels. If anyone comes across any new figures, especially direct from Nissan, please post here. I wish Nissan would just come out and give us some exact numbers.Ĭlick to expand.yes ok, so that reinforces the point that it is able to get up there in speed. Downforce must be far less than what SCC is quoting. The actual drag figure (and therefore the actual downforce figure too) must be a lot smaller since they are for the most part fixed by ratio (there are exceptions but not to any significant degree with road cars). And we know it doesn't have anywhere near that kind of power.Īt similar speeds, these drag figures are also way higher than almost all production and racecars on record, especially these days. and at that speed it is still about 1903 lbs drag (assuming chart is right), requiring 950 whp to overcome. It's also been written that GTR without electronic intervention will go onward to about 186 mph, so we know it can get up there in speed. This is an enormous amount of drag and will require around 1000 whp to overcome. Plugging 740 lbs of downforce at 200mph, you end up with 2220 lbs of drag at 200mph. I hate to think I'm botching up such simple calculation, but just scribbling on paper I'm quite sure something's wrong.Ĭl around -0.09 (or +0.09 by F1 convention)Īt L/D 0.3, every unit of downforce is accompanied by 3 units of drag. Either that, or the chart Nissan published is wrong, because none of the numbers match. I think the numbers quoted by some magazines including SCC are misquotes of Nissan engineers, or the Nissan engineers mis spoke. ![]() I don't think this is what's happening though. Or because for some reason Nissan is using two separate reference areas for lift and drag which would be very unconventional, and possibly invalidate that L/D reference chart they published. There is a huge discrepancy between all the different sets of downforce and drag figures and calculations I've seen so far, I think partly because of the lack of official figures.
