The SSC Ultimate Aero is an American-built mid-engine supercar by Shelby SuperCars. SSC stands for Shelby SuperCars and TT stands for Twin Turbo. It is faster than its rival, the Bugatti Veyron. Its higher-performance limited production version, the SSC Ultimate Aero TT,[1] is the fastest production car in the world, with a recorded speed of 413 kilometres per hour (257 mph).[2] This speed was achieved during tests on September 13, 2007 in West Richland, Washington, United States and verified by Guinness World Records on October 9, 2007.[3]
The Aero and the Shelby SuperCars company are the brainchildren of Jerod Shelby (no relation to car designer Carroll Shelby), who spent over seven years designing the car. Although the basic Aero model is no longer produced, the Ultimate Aero is still in production with an MSRP of around $654,400.[4]
Prototype (2004)
SSC Ultimate Aero SC/8T prototype #001 was built using a supercharged engine sourced from the Corvette C5R mated to a G-64 6-speed manual transmission (also seen in the Dodge Viper). It weighs 1,270 kilograms (2,800 lb). Prototype #001 was sold in 2008 Barett-Jackson Palm Beach auction with winning bid price of $189,200.

Specifications (2006)
Styling of the Aero includes the use of butterfly doors similar to those found on the Mercedes/McLaren SLR, Saleen S7, Mercedes-Benz CLK-GTR, and the Ferrari Enzo. Carbon fiber and titanium are used throughout the car, helping to limit the weight to 1,293 kilograms (2,851 lb) for the standard Aero. Rumors persist that the Ultimate Aero TT is nothing more than a stripped down racing version of the base Aero (rumors that the car has no air conditioning for example); however, such claims have been proven false.[5][6]
The engine in the base Aero model was a Supercharged V8 Chevrolet Small Block series engine rated at 792 kilowatts (1,062 hp) at 6600 rpm and 1,357 N⋅m (1,001 lbf⋅ft) at 5800 rpm, with the supercharger at 55 kilopascals (8.0 psi) and running on 91 octane gasoline. The Ultimate Aero has increased engine displacement of 6.34 L (387 cu in) and increased boost of 96.5 kilopascals (14.00 psi), resulting in 855 kW (1,147 hp) at 6950 rpm and 1,113 N⋅m (821 lbf⋅ft) at 6200 rpm, running on 91 octane gasoline.[6]
Wind tunnel testing indicates that the Ultimate Aero could theoretically reach a top speed of 439 km/h (273 mph) given appropriate transmission gear ratios, although the supplied transmission would result in 418 km/h (260 mph)[6] at the car's redline. The base Aero, however, should "only" reach about 380 km/h (236 mph).[7] The Ultimate Aero accelerates from 0-96 km/h in 2.78 seconds,[8] slower than the Bugatti Veyron which achieves 0-96 km/h in 2.46 seconds because of its 4WD layout and quad-turbocharged W16.[9]
Specifications (2007)
The engine in the base Aero model is same as the previous year, but the Ultimate Aero has a 6.35 litres (388 cu in) engine, rated at 882 kilowatts (1,183 hp) at 6950 rpm and 1,483 newton-metres (1,094 lbf⋅ft) torque at 6150 rpm, and the supercharger is replaced by a twin turbocharger with cabin adjustable boost pressure. The car is designed to use 91-octane gasoline.[10] The 6-speed transmission is readjusted to increase the theoretical top speed to 437 kilometres per hour (272 mph) at 7200 rpm.
Wheels on the base model are sized 460-millimetre (18 in) at the front and 480-millimetre (19 in) at the rear, while the Ultimate Aero TT has wheels an inch larger at each end.
The 2007 models are heavier, with the base model weighing 1,293 kilograms (2,851 lb), and Ultimate version 1,250 kilograms (2,760 lb). Unlike the previous year, base models have a navigation system, 10-speaker audio/CD/DVD system, video/DVD screen, back-up camera, air-conditioning, and trunk space as standard equipment. These come optional on the Ultimate.
The first production 2007 Ultimate Aero TT car was sold on eBay for US$431,100. Later cars are expected to cost US$485,000.[11] Only 24 Ultimate Aero TTs are going to be produced from 2006-2007. The Ultimate Aero TT made its international debut on the International Show Circuit in November 2006.
Specifications (2008)
In 2008 models of Ultimate Aero, 3 changes were made:
- New Twin-Turbo V8
- All new aluminum engine block
- Standard HRE Monoblok wheels
- Azentek Atlas computer infotainment system[12]
The '08 Aero TT was to have a theoretical top speed of 430 km/h (267.19 mph)
Specifications (2009)
The new Ultimate Aero has 15% more horsepower and theoretically capable of reaching 287 mph (462 km/h), with 6th gear rated top speed of 287.102 mph (462.046 km/h). In order to prevent the engine from overheating, airflow to the engine has increased 20% with new carbon fiber louvers. The nose has been redesigned to make the car more aerodynamic, and the interior has been redesigned. The new Aero also has a new AeroBrake system, which is a spoiler that rises up to 8 inches when the brake is pressed to slow the vehicle.[13]

Ultimate Aero EV
SSC announced the production of the Ultimate Aero EV, an electrical version of the sports car.[14] The released specifications include using 500 horsepower (373 kW) electric motor, with SSC also exploring the potential of using 2 engines in 2 or 4 wheel drive configuration. The SSC, once in production, will be the fastest electric car on the market. "I think we can do it faster, leaner and cleaner than any other manufacturer," claims the SSC founder, Jerod Shelby. SSC planned to produce its first prototype in February 2009, with production to begin as early as Q4 of 2009.
As part of the production plan, SSC also announced it had contracted with Sheffield International Finance Corporation to initiate the company's first acceptance of outside capital since its inception.[15]
SSC announces electric powertrain and Ultimate Aero EV specifications.[16] ". SSC will display its AESP in the Ultimate Aero EV in order to prove that electric-powered vehicles will not only match but also provide more linear power ... and overall performance than internal combustion cars. The Ultimate Aero EV uses a twin motor AESP producing an astounding 1,000 HP and 800 lb-ft of torque enabling it to rocket to 60 mph in a mere 2.5 seconds and reach a top speed of 208 mph. Not only does the Ultimate Aero EV have a range of 150-200 miles on a single charge, but SSC's "Charge on the RunTM" onboard charging system allows for full battery recharges in as little as 10 minutes. Mind you, this is not the solution for perpetual motion."

Speed attempt
SSC tested the top speed capability of the Ultimate Aero TT on March 22, 2007. The original test was scheduled for March 21, 2007 but was called off due to bad weather conditions. SSC closed down a 12-mile (19 km) stretch of U.S. Route 93 in Nevada for the event. Their goal was to replace the Bugatti Veyron as the fastest production car ever produced, which at the time could achieve 253.5 mph (408.0 km/h). Simulation and testing at NASA's Virginia facility had shown that the Ultimate Aero TT is theoretically capable of approximately 273 mph (439 km/h).[17] The March 22nd attempt failed to break the record, due to sub-optimal conditions. Test driver Rick Doria reported "wheel-spin" at speeds above 190 mph (310 km/h).[18] Despite the failure of the attempt, the car still reached 242 mph (389 km/h).
SSC announced they had broken the speed record for the world's fastest production car with 256.18 mph (412.28 km/h) in West Richland, WA on September 13, 2007. The reported record speed came from an average of two runs in opposite directions, in accordance with Guinness Book of World Records rules. The first run clocked 257.44 mph (414.31 km/h) and the return trip 254.91 mph (410.24 km/h). The results of this test, verified by Guinness World Records on October 9, 2007, gave the SSC Ultimate Aero the title of world's fastest production car, with a top speed of 256.18 mph (412.28 km/h).[19] This beat the previous record holder, the Bugatti Veyron, that has a top speed of 253.81 mph (408.47 km/h).
In addition to the fastest production car record, SSC also applied for the world record for the highest horsepower for an emissions-legal production automobile.[20]
The record-breaking 2007 Shelby SuperCars Ultimate Aero Chassis #TT-02 was later put into auction by Shelby SuperCars, which also included SSC World Record commemorative watch, key fob, original record-breaking wheels and tires, framed official Guinness World Records certificate with commemorative photo signed by Shelby SuperCars team.[21]
