Supercars are not easy to afford. Even the supercars touted as "affordable" are something many of us can only dream of buying, let alone maintaining. The top tier of supercars is a whole new game though, and its where automakers start truly testing the boundaries of technology, power delivery, grip, and in some cases, ostentatiousness.

Cutting edge technology doesn't come cheap and there's a surprising amount of automakers and supercars at the top-end of the market. This isn't just a list of the most expensive top-tier supercars, but the ones we find most impressive and would try selling our neighbors kids on eBay for the chance to own.

Porsche 918 Spyder

Almost predictably, Porsche made only 918 units of its boundary-pushing hypercar. The 918 Spyder was the statement of intent of how Porsche planned to use hybrid technology. There's no attempt here to save fuel as it's all about using the electric motors to take performance to the next level. Porsche priced the 918 Spyder at $845,000 but after all the units were built by 2016, it's already commanding prices in the millions.

Aston Martin Vulcan

When you think of Aston Martin, it's generally going to be gorgeously sculpted and sophisticated GT cars fit for a spy living a multi-continental lifestyle most of us can only dream of. The Vulcan is not that. Instead of a luxurious GT car, Aston Martin built a full-strength track car that isn't legal for the road. Its inspiration comes from Aston Martin's road cars, but the Vulcan is an edgy and angry looking beast powered by an apoplectic naturally aspirated V12 designed to shave off lap times. Only 24 were built and you won't get one for less than $2.3 million if you can find it.

Koenigsegg Agera RS

The Agera has been around since 2011 and still impresses with a level of engineering precision and performance that's nothing less than stunning. Only 25 have been made, and for those with the couple of million dollars to buy one, then an upgrade will bring the Agera RS up to 1,360 horsepower. A 0-60 mph time of 2.8 seconds is crazy enough, but when you consider it will touch 124 mph in under seven seconds then its easy to understand why it's still relevant.

Bugatti Veyron EB 16.4

There have been four generations of what's probably the most well-known supercar on the planet. The third generation became the fastest street-legal production car in the world when it hit 267.8 mph in 2010, although the one you can buy if you have multiple millions tucked away in a mattress will be limited to 258 mph so the engine won't disintegrate. If you prefer a roof-off 250+ mph experience, then you'll want the 16.4 Grand Sport Vitesse SE model that ended the Veyron 's production run in 2015 at a price of $2.2 million.

Pagani Huayra

The Huayra was Horacio Pagani's difficult second solo album. Pagani's first car, the Zonda, blew minds and stole the production-based car Nurburgring lap record from Ferrari in 2010. The Huayra may look suspiciously like the Zonda, but it was a complete redesign and only 100 were made in agreement with Mercedes-AMG who supplied the specially produced twin-turbocharged 6.0-liter V12 engine. The base price was $1.1 million but for the latest BC track-focused version, the lucky 20 that ordered one paid around $2.3 million.

Lamborghini Sesto Elemento

Very few companies in the world do drama like Lamborghini. Sesto Elemento translates as "Sixth Element," in a nod to the copious amounts of carbon-fiber used in its construction. The chassis, body, and seats are made of carbon fiber, as is the driveshaft and as many of the suspension components as possible and the result is 2,202 lbs of track-focused car driven by a 5.2-liter V10 and a power-to-weight ratio of 3.86 lbs per horsepower. For some perspective, that's putting 562 horsepower into something that weighs close to the same as a fully loaded Fiat 500. Unlike a Fiat 500 though, only 20 were made and, if you can find one, don't expect much change from $3,000,000.

Ferrari LaFerrari Aperta

Aperta literally means "open," and this is the open top version of Ferarri's LaFerrari. It uses the same mid-rear mounted 6.3-liter F140 V12 working with the Formula 1 based HY-KERS kinetic energy recapturing system but with a few upgrades to deal with the extra weight needed to strengthen the chassis after losing the roof. The price tag of $2.2 million dollars is a full $1.2 million more than the original LaFerrari when it first sold in 2013.

Koenigsegg Regera

The Regera is another extraordinary Christian von Koenigsegg vision made real and has an extraordinary price tag of $2.2 million attached. The Regera's drivetrain is based around a 5.0-liter twin-turbo V8 that pushes out 1,100 horsepower, but also features the Koenigsegg Direct Drive system. That system is a crank-mounted electric motor connected via a hydraulic coupling to the engine to act as a launch motor to fill out the bottom of the torque curve. On top of that, each of the rear wheels has its own electric motor.

The end result is a smooth and instant delivery of relentless power that will get the car to 186 mph in 10.9 seconds. To get an idea of how relentless that actually is, 93–155 mph takes place in 3.9 seconds.

McLaren P1

The P1 was a one of the "Holy Trinity" of hybrid hypercars alongside the Porsche 918 Spyder and Ferarri's LaFerrari. It's a wonder of technical achievement and outright performance blended with daily drivability and a reputation for biting a driver that doesn't respect it when driven at the edge. The P1 originally sold for $1,350,000 but you're going to have to check your bank account for around $2.0 million if you want one now.

Ferrari F60 America

Ferrari's limited production run of 10 roadster derivatives of the F12berlinetta were built to commemorate 60 years of Ferrari in North America. The F60 is a pure modern-day homage to Ferrari's early era convertibles. The 6.3-liter naturally aspirated V12 has a surprisingly strong 18 mpg rating due to its start-stop technology and will take the beautifully-crafted F60 from 0-62 mph in 3.1 seconds. All ten were sold before they were built at around $2.5 million each.

Bugatti Chiron

The Veyron is still the fastest Bugatti on paper, but only because the tires don't exist yet to make a top-speed record run with the Chiron. In every other measurement, the Chiron is faster. It takes the extra 300 horsepower and blisters to 60 mph in a frightening 2.4 seconds and gets to 124 mph in 6.4 seconds. It set the record for getting to 249 mph by doing it in just 32.6 seconds, and then got back down to 0 mph in an eyeball pulling 9.4 seconds. The first 200 Chiron models to roll out of the factory sold for $2.7 million each before they were made.

W Motors Lykan HyperSport

W Motorsports is based in Dubai and the Lykan HyperSport is the first Arabic supercar. Its performance is supercar quality with a mid-rear mounted 3.8-liter twin-turbocharged flat-6 boxer engine that develops 780 horsepower. It'll accelerate to 60 mph in 2.8 seconds and top out at 240 mph. That isn't why it has an astonishing $3.4 million price tag though. The HyperSport's party piece is the headlights that feature titanium LED blades that have a total of 420 15-karat diamonds embedded in them.

You didn't read that wrong. The headlights are embedded with 420 15-karat diamonds. Of course, if you have that kind of money you can choose whatever damn jewels you like to go there and, according to Lykan, customers have also chosen rubies, sapphires, and yellow diamonds as well.

Lamborghini Veneno

The Sesto Elemento is Lamborghini's lightest car, but the Veneno is the Italian automaker's most expensive. In essence, the Veneno uses a carbon-fiber version of the LP700-4 Aventador's monocoque chassis, pushrod-actuated suspension, a 740 horsepower 6.5-liter V12 engine, and the seven-speed single-clutch ISR automated manual transmission you'll also find in the Aventador.

Just how expensive is it? When introduced, the price tag was a stunning $4,500,000.
