Koenigsegg Agera R $ 1.6 million. The Agera R can burn 0-60 in 2.8 seconds, reaching a top speed of 260 mph. It includes elements to reach 270 mph, but the supercar is electronically capped at 235 mph. With the completion of certain documents, the company will open the speed limit for one occasion.
Shadow R1 5(AC) Sqdn RAF Waddington. RAF Shadow R.1 is based on King Air 350 platform, an aircraft that has seen widespread use since introduced a few years ago for service in the Middle East and Afghanistan. The basic aircraft has a massive user base (over 6,000 aircraft), is safe and reliable with proven performance and great adaptability. It has a high top speed, plenty of endurance and payload (for sensors, DAS and Comms) and pressurised cabin, perfectly suited to the role.
Koenigsegg Agera R: $1.6 million Debuting in 2011, the Agera R can accelerate from 0–62mph in 2.8 seconds and has a theoretical top speed of 273 mph. It also set several land speed records for a two-seat production car: it can go from zero to 300 kilometers per hour then back to zero in 21.19 seconds.
6. Koenigsegg Agera R — $1.6 million. Rather than running on regular gas, the Koenigsegg Agera R runs on biofuel — essentially fuel produced from living organisms such as plants and microalgae. Yes, it's that special. With a 0 to 100 km/h acceleration time of just 2.9 seconds, and a theoretical top speed of 443 km/h, the Agera R stands among the most powerful, and expensive, cars on the planet — and it's environmentally conscious to boot.
7. 9ff GT9-R — 1,120 hp at 6,400 rpm: Surely if John Hennessey's hyper-modified Lotus Elise/Exige counts, so does the 9ff GT9-R. 9ff starts with a basic 911, stretches it to allow for a proper midengine layout and then drops in a 4.0-liter twin-turbocharged flat-6 good for 1,120 hp. Top speed: 260 mph.
