2. KOENIGSEGG AGERA RS: 278 MPH
In terms of spec sheets, Hennessey’s Venom F5 is more impressive. Its claimed top speed of 301 mph obliterates everything else on this list by a significant margin, but Hennessey hasn’t verified its numbers with the Guinness Book of World Records. Koenigsegg has, so even though it gets the silver medal here, in the real world, the Agera RS is the true speed king.
To set the official record, Koenigsegg asked the Nevada Department of Transportation to close an 11-mile stretch of Route 160 between Las Vegas and Pahrump. On public roads, the 1,160-hp Swedish supercar hit 284.55 mph during its first run and 271.19 mph during the second, which averages out to 277.9 mph.
