At $1.7 million, the Koenigsegg Agera R is one of the most expensive supercars in the world. With its 5.0-liter V8 that produces 1,115 hp and ability to get to 60 mph in 2.9 seconds, it’s one of the most powerful and quickest too. Only 18 vehicles were produced and this model seen driving around San Francisco, CA is most likely the only one in the US. So seeing it drive around town incredible.
