The Koenigsegg Regera
The Koenigsegg Regera has a top speed of 251 mph (404 km/h). It can accelerate from 0 to 62 mph (100 km/h) in 2.8 seconds, 124 mph (200 km/h) in 6.6 seconds, 186 mph (300 km/h) in 10.9 seconds, and 249 mph (400 km/h) in 20 seconds. Getting from 0 to 400 km/h (249 mph) and back to a standstill as quickly as possible has become a hotly contested acceleration and braking benchmark for the world's fastest hypercars. It's not just a test of engine power and braking grip, it's also an extreme test of traction control, ABS, active aerodynamics, and suspension systems. And it's probably appropriate; a lot of multi-million dollar hypercars aren't focused on racetrack times, but they do offer 1,600-plus horsepower and outrageous top speeds. And since they're driven by, well, whoever can afford them rather than the world's most skilled drivers, the companies that make them do seem to feel an obligation to make extreme acceleration, high speeds, and savage braking as...
