Swedish car firm Koenigsegg has broken the speed record for a production car after recording a two-way average speed of 277.9mph in the Agera RS (pictured). Driver Niklas Lilja did the run at Pahrump, Nevada, and the speed breaks the previous record holder, the Bugatti Veyron Super Sport, which recorded a speed just shy of 268mph in 2010.Just last week the Hennessey Venom F5 was unveiled and it has a projected top speed by the company of over 300mph. If achieved, this would comfortably break the record, now held by the Koenigsegg.High time to take a look at the world’s fastest cars, and how they stack up at the moment. Autocar has driven nearly all of these cars, so we’ll throw in our driving observations along the journey.
McLaren 675LT – 205 mph
A development of the McLaren 650S, the Longtail has a 3.8-litre twin-turbo V8 that produces 666bhp and is 100kg (220 lbs) lighter than its donor.Our verdict: “Don’t want one only because the 675 LT is quick. The difference you’ll note from behind the wheel is not necessarily how much faster you’d be going than in a 650S, but how much more fun you’re having while you’re doing it.”
