As for the new image, we see a pair of exhaust pipes that are exiting out of the top and rear of the engine bay. We've yet to see a modern McLaren with this type of exhaust, as most have exhaust exiting directly out of the rear. One car you may be familiar with that has a similar exhaust setup is the Porsche 918 Spyder, which has exhaust exiting behind the driver and passenger seats.
This new model will have increased power, a lighter weight, better aerodynamics, and "enhanced driver engagement." Production of the car will also be very limited.
McLaren will be taking the mystery car for a drive up the famous Goodwood Hill Climb on July 12. After it's unveiling, McLaren will have unveiled five models under the Track22 business plan.
