3. Koenigsegg Agera R

Top Speed: 273 mph (theoretical)

Debuting at the March 2011 Geneva Motor Show, the Koenigsegg Agera R is one of the fastest cars ever built. During test sessions in Ängelholm, the Agera R broke six world land speed records for a production car, including 0–189 mph in 14.53 seconds, and 0-189-0 mph in only 21.19 seconds. The braking performance required to maintain this record is enabled in part by the Agera’s stability, demonstrated by Koenigsegg’s test driver and drivetrain technician Robert Serwanski, who was able to brake from 186 mph to 0 without holding the steering wheel. The adaptive rear wing system is lighter than conventional hydraulic/electrical adaptive systems, and has the unique ability to compensate for head/tailwind due to its spring-loaded design.
