# Top 50 Supercars listed by power to weight ratios

What do motorcycle riders and Formula 1 drivers have in common? They know the benefits of a large power to weight ratio.

Big power + Light weight = Massive Power to Weight ratio and lots of smiles all around. If you ride a motorbike you get to skip lugging around a few thousand pounds of windows, doors and safety equipment and in return your engine has less to drag around, which definitely livens things up.

Formula 1 drivers are probably the biggest power-to-weight ratio junkies of anyone because the typical power-to-weight ratio of a standard Formula 1 car is around four hundred and twenty-two watts per pound. That will do me just fine.

So, what is power to weight ratio?

Power-to-weight ratio (or specific power or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. The engine’s power output is divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle’s size.

It basically means that you can’t just focus on horsepower because it only shows one side of the story when it comes to a car’s speed and performance. If you really want to know how fast a car is you need to know the power to weight ratio (the higher the number is, the better).

Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle.

By cutting on down the weight of a car, car makers can increase the speed and performance of their supercars. The more power a car has per pound, the higher the power-to-weight ratio.

Here’s a comparison of power to weight ratios for context:

Koenigsegg released an upgraded version of their fastest car called the CCXR Special Edition. The most obvious change is a contoured rear wing which is permanently fixed. This was probably motivated by Top Gear and Jeremy Clarkson who requested a larger wing to steady the car during its second visit at the show. Beyond the wing, only detail changes such as uncovered headlights, color-coded carbon fiber and new suede seats are fitted. Learn about the 2007 Koenigsegg CCXR Edition.

#### 42. 2007 Weber Sportscar

Power to Weight (hp/lb) 33.74 | Power to Weight (hp/ton) 818.18

Weber Sportcars from Tobel, Switzerland are dreaming big with their latest mock-up revealed at the 2007 Top Marques Monaco show. What they have in mind is a 250 mph, carbon fiber supercar that is shaped largely by aerodynamics. After nine months of computer-aided design, they were able to make a full size model of what the final shape might look like. Included is an active rear wing that changes in angle for both acceleration and braking. Power for the car comes from a 7.0l supercharged V8 that will churn out 950 bhp to the rear wheels.

#### 43. Ferrari LaFerrari

Power to Weight (hp/lb) 30.16 | Power to Weight (hp/ton) 599.37

The LaFerrari is the first car in Ferrari history to be powered by the HY-KERS system. With a 6262 cc V12 that punches out 800 CV and revs to a maximum of 9,250 rpm. It also features a very high 13.5:1 compression ratio and a high specific output equal to 128 CV per litre. The engine is coupled with a 120 Kw (163 CV) electric motor, giving it a combined power output of 963 CV.

The high torque levels available at low revs from the electric motor allowed the engineers to optimise the internal combustion engine’s performance at higher revs, thus providing a constant supply of exceptional power throughout the rev range. Total torque generated is in excess of 900 Nm. Learn about the

#### 44. Bugatti Veyron 16.4 Super Sport

Power to Weight (hp/lb) 29.22 | Power to Weight (hp/ton) 653.00

Bugatti describes the Super Sport as “a car with a uniquely high performance of 1,200-hp (882 kW) offering experienced drivers a whole new dimension of excitement, with a maximum torque of 1,500 Newton metres”. We say it is an animal. Acceleration is manic and unlike anything you will ever experience. Perhaps most amazing is how relentless the acceleration is all the way past 200mph, continuing to pull hard to the end. Learn about the

#### 45. 2013 McLaren P1

Power to Weight (hp/lb) 28.25 | Power to Weight (hp/ton) 623.17

The McLaren P1™ will have the combined force of two highly-efficient powerplants, offering the optimum mix of superb throttle response, day-to-day drivability and top speed. A mid-mounted 3.8-litre twin-turbo V8 petrol engine and a highly effective electric motor give a combined output of 916PS (903 bhp) and a maximum torque figure of 900Nm, ensuring instantaneous throttle response through the rev range, more akin to a naturally aspirated engine. Emissions of less than 200g/km on the combined cycle are reduced to zero in full electric drive mode, while the Formula 1-derived DRS and IPAS technologies offer an increase in straight-line speed and an instant boost of power. Learn about the

#### 46. Caterham Seven 620R

Power to Weight (hp/lb) 25.83 | Power to Weight (hp/ton) 598.08

A newly-engineered, two-litre supercharged Ford Duratec engine pumps out 310bhp, providing even more of a kick in the back for the driver and propelling the Seven 620R from 0-60mph in under 2.8 seconds. Learn about the

#### 47. Pagani Huayra

Power to Weight (hp/lb) 24.83 | Power to Weight (hp/ton) 547.41

The engine is a version of the Mercedes-Benz V12 specifically developed for Pagani. Called the M158, power output is raised to nearly 700 with use of two turbochargers. The all-new monocoque central Huayra is built in carbon-titanium, with its gullwing doors that include a good portion of the roof. The research focused on the application of advanced composite materials and technologies first tested on the Zonda R, to achieve the highest levels of rigidity combined with maximum lightness. I guess that’s why Pagani finds itself on our list of cars with the best power to weight ratio. Nice work Mr Pagani. Learn about the Pagani Huayra.

#### 48. Porsche 918 Spyder

Power to Weight (hp/lb) 24.53 | Power to Weight (hp/ton) 521.76

Put the Porsche 918 Spyder in “Race Hybrid” mode for maximum performance and the car accelerates like it is on a slingshot. The 918s combustion engine is chiefly used under high load with the electric motors providing additional support in the form of boosting. My guess is that repeated acceleration runs would need the electric power assist to rocket the car to the quarter mile in under 10 seconds. Learn about the

#### 49. 2006 Bugatti Veyron

Power to Weight (hp/lb) 23.71 | Power to Weight (hp/ton) 490.45

After years of applause, celebration, doubt, then ridicule, the first production Bugatti Veyron has hit the road as the fastest available supercar. A pre-production car achieved a two-way average speed of 252.95mph at parent company Volkswagen’s Ehra Lessien test track in Germany. The Veyron destroyed records. It was the fastest accelerating (0-60 in 2.46 seconds), most consuming (5.82 mpg), most expensive (1,440,800 USD) and quickest (253 mph) production car available and it did so in dramatic fashion. An icon. Learn about the 2006 Bugatti 16/4 Veyron.

#### 50. Ferrari 458 Speciale

Power to Weight (hp/lb) 19.41 | Power to Weight (hp/ton) 430.11

The 458 Speciale’s mid-rear-mounted 4497 cc GDI engine is the most powerful naturally aspirated Ferrari 8-cylinder ever developed, punching out 605 cv at 9000 rpm and maximum torque of 540 Nm at 6000 rpm, while its record 135 cv/l specific power output is also the highest ever achieved by a naturally-aspirated road-going engine. The 458 Speciale’s increased power and torque are also the result of redesigning various engine components and reducing internal friction. Most of the bodywork panels have been redesigned without modifying either the passenger cell or the signature design features of the 458 Italia. The thickness of the glass used has been reduced to cut weight, while the rear windscreen is now a Lexan© panel. Learn about the Ferrari 458 Speciale.
