It's a three-way tie for the #1 spot, but Tesla still carries the torch.
If you desire owning the world's quickest road-going production car, then the Tesla Model S P100D with Ludicrous is by far your most sensible choice.
With its 2.28-second time from 0 to 60 mph, the Model S P100D became the world's quickest production car some time ago. It's top spot has been challenged, but no vehicle has surpass the mighty Tesla yet, not even the single-seat, stripped down Dodge Challenger SRT Demon.
Autocar compiled a list of the Top 10 quickest production cars available today and sure enough, the Model S P100D sits in the number one spot (shared with two other cars, both of which are single-seaters and one is a plasticy kit car).
Ultima Evolution Coupe
Here's Autocar's blurb on the trio of #1 quickest cars:
1: Ultima Evolution Coupé, Dodge Challenger SRT Demon, Tesla Model S P100D – 2.3sec to 60mph
The term 'race car for the road' is bandied around fairly liberally, but it’s hard to envisage a more accurate description for the 1020bhp, 6.8-litre supercharged V8-engined Ultima Evolution Coupé. Meanwhile, Dodge strapped a mammoth supercharger and other performance parts to the Challenger Hellcat to create the wheelie-pulling, 829bhp SRT Demon, and Tesla upped the largest battery pack of its Model S saloon to 100kWh, and managed a time of 2.28sec.
And here are the remaining Top 10 (yep, that's a second Tesla on the list - the only automaker with two in the Top 10. And there's the electric Rimac Concept One too):
2 - Bugatti Chiron
3 - Ariel Atom 3.5R
4 - Rimac Concept One
5 - Koenigsegg Regera
6 - Hennessey Venom GT
7 - Caterham 620R
8 - Tesla Model S P90D
9 - BAC Mono
10 - Ferrari F12tdf, Lamborghini Aventador, Porsche 911 Turbo S
