Our friends over at CarMagazine have spotted a mystery supercar at a UK facility. While Car’s first inclination was a Lotus Esprit, all inquiries so far say it isn’t.

What we know so far is that the prototype in the pictures is mid-engined and is powered by a 7.0 liter V8 engine producing up to 512 horsepower with 470 lb-ft of torque.

Other speculations say that this is McLarens upcoming baby supercar since it has similar proportions. Some say that this may also be the new Noble since an upgraded M15 is long overdue.
