Audi has unveiled a new supercar, the Nuvolari, which is reported to have over 1,000 horsepower, although one outlet suggests it may have 978 horsepower. The car has been spotted being tested at the Nurburgring, and it is expected to arrive next year, potentially as a replacement for the R8. However, details about the car's powertrain are unclear, with some outlets suggesting it has a V8 engine and others indicating it may be a hybrid or have a Lamborghini-powered engine.
