How Koenigsegg broke the land speed record with its Agera RS

Tires. Downforce. Weight. Horsepower. Aerodynamics. When you're going 277 miles per hour in a production car, everything matters

This month a Koenigsegg Agera RS hit the highest speed ever for a production vehicle.

Driver Niklas Lilja averaged a top speed of 277.87 mph across two runs in the $2-million coupe on a 11-mile, closed-off stretch of Highway 160 near Pahrump, Nevada. 
 

That beat the previous record of 267.8 mph set by a Bugatti Veyron Super Sports model seven years ago in Germany. It also beat the Hennessey Venom GT and McLaren F1 that had previously owned or approximated similar top speeds.  

What’s more, Lilja set records for highest speed in a single direction on a public road
