Unfortunately for the automotive world, there are legal limitations on what can be driven on public roads. Thankfully, there are tracks all across the world to accommodate those non-street legal supercars so automakers can continue pushing the envelope. Here’s our top 10 amazing cars you can’t legally drive on the street.
Aston Martin Vulcan
Recently introduced, the Aston Martin Vulcan is arguably the best looking machine the British automaker has ever created. For a brand that has built its reputation by teaming up with James Bond, the Vulcan is likely more car than 007 would ever need. Using a 7.0-liter naturally aspirated V12 engine designed and developed in collaboration with Aston Martin Racing, the Vulcan has more than 800 horsepower and a completely carbon fiber chassis. This track-only supercar will be limited to just 24 units worldwide and comes with carbon-ceramic disc brakes matched to Brembo racing calipers. Oh yeah, did we mention it costs around $2.3 million?
Dodge Viper ACR-X
The track-only version of the Dodge Viper ACR was built to commemorate the end of the second-generation Viper. Named Viper ACR-X, the purpose-built race car was powered by an 8.4-liter V10 engine mated to a six-speed manual transmission, packing 640 hp and 605 lb-ft of torque. Fully adjustable suspension along with staggered 18- and 19-inch wheels paired to Michelin slicks helped make the Viper ACR-X one of the most venerable cars to ever hit the track. Just how good did it perform? It turned in a Nurburgring lap time of 7:03.06, good enough to make it the third-fastest track-only car ever.
One of those cars that bested the Viper ACR-X’s Nurburgring time is the Ferrari 599XX, stopping the clock at 6:58.16. Sporting a 6.0-liter V12 engine churning 720 hp and 506 lb-ft of torque, the 599XX was a track-only iteration of the 599GT Fiorano with more hardcore aerodynamics and a stripped interior. The race car comes in about 600 pounds lighter than the 3,953-lb 599GTB Fiorano and has 108 more horsepower and 58 lb-ft more torque. It did the sprint from zero to 62 mph in just 2.9 seconds without launch control and was limited to just 29 units.
Ferrari FXX K
Ferrari’s latest track-only machine is considered a hypercar: it produces 1,036 hp and is based on the LaFerrari. Along with enhanced aerodynamics, the Ferrari FXX K has 664 lb-ft of torque to back up its four-digit horsepower figure through a 6.3-liter V12 engine paired to an electric motor. Up front are massive 15.7-inch carbon-ceramic Brembo disc brakes while the rear gets impressive 15-inch rotors. No official Nurburgring time has been announced for the FXX K, but rumor has it that it completed a lap in 6:35. Priced more than $3 million, fewer than 40 will ever be built.
Lamborghini Murcielago R-GT
Based on the standard Murcielago, the R-GT was developed jointly with Reiter Engineering and Audi Sport. Unlike the standard Murcielago, the Murcielago R-GT was rear-wheel drive only, with the Italian automaker producing a mere nine units so that it could comply with race rules. The R-GT was equipped with the same 6.0-liter V12 engine with power output set at 580 hp and 443 lb-ft of torque while tipping the scales at 2,425 lbs.
Lamborghini Sesto Elemento
Lightweight, powerful and stunning, the Lamborghini Sesto Elemento has an overall curb weight of just 2,202 lbs. The 5.2-liter V10 engine was borrowed from the Gallardo to produce 570 hp and 400 lb-ft of torque, helping the exotic go zero to 60 in less than 2.5 seconds. Only 20 units were ever produced and were reportedly priced between $2.2 million to $2.9 million.
McLaren P1 GT-R
McLaren wasn’t going to sit idle as Ferrari unleashed the FXX K. The British automaker conjured up its track-only weapon with the P1 GTR, which is only available to current P1 owners. Now, it’s not as powerful as the FXX K since it has “only” 986 hp, but it does use a 3.8-liter twin-turbo V8 paired to an electric motor, just like its P1 counterpart. Aerodynamic improvements result in a 10 percent improvement in downforce while the British automaker managed to strip away 110 lbs of weight. A total of 45 units will be produced, but the company did admit it could make up to 375 units, matching the production figures of the standard P1. Yes, McLaren actually thinks every P1 owner wants a P1 GTR.
Mercedes SLR McLaren 722 GT
Some would say this is the hottest Mercedes SLR McLaren of all time. The ultra-rare 722 GT was limited to just 21 units and featured an aggressive widebody, massive rear wing and 19-inch OZ Racing wheels on all four corners. Stripped down to just 3,064 lbs, the SLR McLaren 722 GT was powered by a 5.4-liter supercharged V8 with “well over” 670 hp and 610 lb-ft of torque. The track-only superccar was offered at a cool $1.2 million in the U.S.
Pagani Zonda R
Currently the fastest track-only car on the Nurburgring, the ridiculous Pagani Zonda R holds a 6:47.50 time thanks to an AMG-sourced 6.0-liter V12 engine with 750 hp and 524 lb-ft of torque. Limited to just 15 units, the Zonda R is built on a carbon-titanium chassis and comes with Brembo brakes, forged alloy APP wheels and Pirelli P Zero tires. A 12-way Bosch Motorsport traction control and ABS system allows the driver to fully adjust the settings, making it the ultimate track car.
Porsche Cayman GT4 Clubsport
We might be jumping the gun here, since the Porsche Cayman GT4 Clubsport isn’t debuting until the 2015 L.A. Auto Show in November, but we can only imagine how awesome it’s going to be as a track-only variant of the Cayman GT4. Powered by the same 3.8-liter flat-six engine, the GT4 Clubsport will have 385 hp while weighing 2,866 lbs. It will come standard with a welded-in safety cage, a racing bucket seat and a six-point harness. Expect more details on the Porsche Cayman GT4 Clubsport to surface ahead of its world premiere on November 18 in Los Angeles, California.
