Too Extreme to Handle on Roads: Supercars considered not to be Street Legal

 

MCLAREN 720S GT3X:

Being made more hardcore and extreme by respawning and retuning the 720S The twin-turbocharged V-8 can churn out about 710 hp, way more than the 500 hp output of the 720S GT3, the car on which the GT3X is based. There is also a 'push to pass' system that can temporarily increase this output by 30 hp. There is no shortage of downforce too, thanks to that massive rear wing, an extended splitter, and cleverly positioned dive planes to control airflow around the sides of the car.

ASTON MARTIN VULCAN:

This fire-breathing monster comes loaded with a potent 7.0-liter naturally aspirated V12 engine that makes 820 hp at 7,750 rpm and 575 lb-ft of torque at 6,500 rpm. The lucky owners need to undergo a special training class by professional racing drivers before taking charge of the bonkers machine, capable of rocketing to 60 mph in 2.4 seconds. The Aston Martin Vulcan had its debut at the 2015 Geneva Auto Show and the carmaker would go on to build just 24 examples for carefully selected customers, with one of the cars later converted for road use.

LAMBORGINI ESSENZA SCV12

The production run is capped at 40 units and each one is fitted with the most powerful version of the Lamborghini V12; a power plant that generates up to 830 hp for a sprint to 60 mph in under 3 seconds. It is a machine specifically developed to provide the drivers the Lambo track experience and blast through the lap times. That engine combines seamlessly with various aerodynamic features and technical evolutions inspired directly from Lamborghini racing prototypes for breathtaking performances out on the tracks. Lamborghini offers the lucky owners the opportunity to store the cars at the company's headquarters in Italy.

KTM CROSS BOW

The KTM X-Bow can be driven on public roads in Europe but it's a different story once you cross the Atlantic. American regulators remain unconvinced about the safety features built into what they think is little more than a glorified go-kart with way too much power for its own good.

MCLAREN SENNA GTR:

The McLaren Senna ranks right up there with the best modern supercars that exist today. Now, imagine that level of performance dialed up by several notches and you've got this one - the McLaren Senna GTR. It uses the same twin-turbocharged V8 engine found in the Senna but the output is now about 814 hp instead of 789 hp.That massive wing is not just for show and helps the car achieve an incredible 2,200 pounds of downforce at 155 mph.

FORD GT MKII

The Ford GT MK II costs a whopping $1.2 million and will be restricted to a production run of only 45 units. It retains the same low-slung profile as the 'regular' Ford GT but you'll immediately notice the extras like roof scoop, aggressive rear diffuser, and that gigantic wing.
