The Ten Production Cars With The Craziest Power-To-Weight Ratios

We may earn a commission from links on this page.

Horsepower only shows one side of the story when it comes to a car's speed – if you really want to know how fast a car is check out the weight-to-power ratio. Just like golf, lowest number wins.

10.) Pagani Huayra


2980 lbs

740 hp

4.14 lbs/hp

If this list is starting with a wild 740 hp Pagani you know it's going to be interesting. The Huayra is staggeringly light for a car with a V12.

9.) Porsche 918 Spyder Weissach Package


3616 lbs

887 hp

4.08 lbs/hp

The 918 barely edges out the Huayra, but only if equipped with the stripped out Weissach Package, otherwise the Pagani would just have it.

8.) Caterham 620R


1201.52 lbs

310 hp

3.88 lbs/hp

Performance like this in a car that was designed in 1957 is just bonkers. This unassuming little thing is keeping some seriously impressive company here.

7.) McLaren P1


3196.7 lbs

903 hp

3.54 lbs/hp

The McLaren P1 is impressively light given its complex hybrid drivetrain – lighter than a Corvette Stingray.

6.) Bugatti Veryon Super Sport


4162 lbs

1184 hp

3.52 lbs/hp

Unfortunately for the McLaren, the Veryon Super Sport's raw power gives it the slightest edge in weight-to-power. Still though, this is the heaviest car on the list by far and away.

5.) LaFerrari


3150 lbs

950 hp

3.32 lbs/hp

Both the name and the performance of LaFerrari could be described as silly, but we're talking about two different definitions of silly.

4.) Ariel Atom 500


1213 lbs

500 hp

2.43 lbs/hp

Holy crap. Talk about a quantum leap forward: the Atom 500 has nearly a pound less per hp than LaFerrari. Think about that for a minute.

3.) Hennessy Venom GT


2743 lbs

1244 hp

2.205 lbs/hp

God bless America. And England too I guess, since the Venom GT is based off of a Lotus. The incredible ratio explains why it can do this.

2.) Koenigsegg One:1


2954.19 lbs

1340 hp

2.2046 lbs/hp

Koenigsegg's crazy One:1 just barely inches out the Venom GT. It's so close,"inches out" might be an overstatement. Crazy that cars like this exist – almost as crazy as the people who make them.

1.) Caparo T1


1212.54 lbs

575 hp

2.11 lbs/hp

The Caparo T1 is more like a LeMans prototype than a road car but these things are road legal in the UK. Jeremy Clarkson said it accelerated in a way he'd "never ever experienced" which makes sense, given it's absurd weight-to-power.
