Singer's Firefly Commission: A 964-Generation 911 With 710 Horsepower and a 218-MPH Top Speed

Singer built the Firefly Commission from a Porsche 911 of the 964 generation. It makes 710 horsepower and reaches 218 miles per hour. Those are the two numbers any 911 owner will stop on. The car is still recognizably a 964, and those figures are what set it apart. The car is going to auction, and Robb Report Motors says it could sell for close to $4 million. That is the publication's forecast, not a sale price, and we will report the actual result once the car sells. Until then, the Firefly Commission is a one-off Singer build on a well-loved 911, and the numbers above are what we know about it.
