The SSC Ultimate Aero is a mid-engined sports car that was produced by SSC North America (formerly known as Shelby SuperCars) from 2004 until 2013. The SSC Ultimate Aero held the world production car speed record title, according to the Guinness World Records, from 2007 (when it was officially timed at Template:Cvt) until the introduction of the Bugatti Veyron Super Sport in 2010. In April 2013, the Guinness World Records temporarily disqualified the Veyron's record time for a period of five days due to concerns about electronic speed limiting changing the function of the car, but after investigation reinstated the Veyron as the record holder.[1]
The SSC Ultimate Aero was not sold with electronic driver aids such as an anti-lock braking system or traction control system, as according to Jerod Shelby (no relation to Carroll Shelby), "Early design philosophy on the car was to make it a driver's car. I wanted a car that you not only throttled with your right foot but at times you could steer with your right foot and a sensor."
History
SSC Aero SC/8T Number 1 (2004)
The first SSC Aero prototype was completed in 2004 and began road testing in anticipation of the SSC Ultimate Aero production vehicle.
- Engine - Supercharged Template:Cvt LS1-based V8
- Power - Template:Cvt at 6,600 rpm
- Torque - Template:Cvt at 5,800 rpm
- Redline - 7200 rpm
- Top speed - Template:Cvt (claimed)
- Dry weight - Template:Cvt
SSC Ultimate Aero SC/8T Number 2 (2005)
Wind tunnel testing indicated that the Ultimate Aero could theoretically reach a top speed of Template:Cvt given appropriate transmission gear ratios, although the supplied transmission would result in Template:Cvt at the car's redline.[4] The base Aero, however, had a theoretical top speed of about Template:Cvt.[5] The Ultimate Aero accelerates from 0–Template:Cvt in 2.78 seconds,[6] slower than the Bugatti Veyron which achieves 0–100 km/h in 2.46 seconds, partially due to its AWD drivetrain.[7]
Specifications:[4]
- Engine - Supercharged 6,300 cc Chevrolet Corvette C5-R V8
- Power - Template:Cvt at 6600 rpm
- Torque - Template:Cvt at 5800 rpm
- Redline - 7200 rpm
- Max Speed - Template:CvtScript error: No such module "Unsubst".
- Dry weight - Template:Cvt
2006
Styling of the Aero includes the use of butterfly doors similar to those found on the McLaren F1 and Ferrari Enzo. Carbon fibre and titanium are used throughout the car, helping to limit the weight to Template:Cvt for the standard Aero. The SSC Ultimate Aero was the final version of the prototype, introduced in 2006. It had an increased engine displacement of 6,300 cc and increased boost to 100 kPa.

- Engine: supercharged 6,300 cc Chevrolet Corvette C5-R V8
- Power: Template:Cvt at 6950 rpm
- Torque: Template:Cvt at 6200 rpm
- Redline: 7200 rpm
- Top speed: Template:CvtScript error: No such module "Unsubst".
- Dry weight: Template:Cvt
2007–2008
The Ultimate Aero TT was a twin-turbocharged version of the Ultimate Aero. The 6-speed transmission was readjusted to increase the theoretical top speed to Template:Cvt at 7200 rpm. Wheels on the base model are sized Template:Cvt at the front and Template:Cvt 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 Template:Cvt, and Ultimate version Template:Cvt. 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.[8] Later cars are expected to cost US$285,000.[9]Template:Update inline Only 24 Ultimate Aero TTs were produced from 2006 to 2007. The Ultimate Aero TT made its international debut on the International Show Circuit in November 2006. The Ultimate Aero TT claimed the Guinness World Records for the fastest production car, after it was officially timed at Template:Cvt in Washington.[10] For 2008, the Ultimate Aero received four updates:
- New twin-turbocharged V8
- New aluminium engine block
- Standard HRE monoblock wheels
- Azentek Atlas computer infotainment system[11]
Specifications:[10]
- Engine - twin-turbocharged 6,300 cc bored-out LS6
- Power - Template:Cvt at 6950 rpm
- Torque - Template:Cvt at 6150 rpm
- Redline - 7200 rpm
- Top speed - Template:Cvt
- Dry weight - Template:Cvt
SSC Ultimate Aero TT
In 2009, SSC updated the Ultimate Aero TT, with the new version having an increase in power of 15% over the older model. SSC predicts a top speed of over Template:Cvt is possible. In order to prevent the engine from overheating, airflow to the engine has been increased 20% with new carbon fibre louvres. 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 which rises up to Template:Cvt when the brake is pressed.[12] This updated model reached a top speed of Template:Cvt in a test, according to SSC.[13]
Specifications:[13]
- Engine: twin-turbocharged 6,300 cc SSC V8
- Power: Template:Cvt at 6100 rpm
- Torque: Template:Cvt at 6100 rpm
- Redline: 7200 rpm
- Top speed: Template:Cvt
- Dry weight: Template:Cvt
A 2009 SSC Ultimate Aero, albeit with the new prototype SSC Tuatara gearbox fitted, was able to complete six runs of 0–Template:Cvt from 15.1 to 15.8 seconds, according to SSC's gear ratio testing results.[14]
SSC Ultimate Aero EV
In 2009, SSC announced that they would be commencing production of the Ultimate Aero EV, an electrically powered version of the Ultimate Aero. This car featured twin electric motors, claimed to be capable of producing Template:Cvt and Template:Cvt of torque through a three-speed automatic transmission.[15] SSC claimed that the car would be able to accelerate from 0–Template:Cvt in 2.5 seconds, and reach a top speed of Template:Cvt.[15] However, the car never entered production.
2013
In 2013, SSC introduced the Ultimate Aero XT, which was a special version of the Ultimate Aero that was built to celebrate the end of its production. Five XTs were planned, but only one was built. They utilised some components that were designed for its Tuatara replacement; for example, the Ultimate Aero XT was fitted with SSC's new 6.9-litre all-aluminium twin-turbocharged V8 engine and a seven-speed paddle-shifted gearbox.[16]
- Engine: twin-turbocharged 6,900 cc SSC V8
- Power: Template:Cvt at 6800 rpm
- Torque: Template:Cvt at 6800 rpm
- Redline: 9100 rpm
- Top speed (theoretical) - Template:Cvt
- Top speed (actual): Template:Cvt
- Drag coefficient: Template:Cd
- Dry weight: Template:Cvt
- Kerb weight: Template:Cvt
Speed record
Simulation and testing at NASA's Langley Research Center had shown the Ultimate Aero TT theoretically capable of attaining about Template:Cvt,[19] sufficient to surpass the production car record-holding Bugatti Veyron's Template:Cvt.
A Template:Convert stretch of Route 93 was closed on March 21, 2007, to allow SSC to test the Ultimate Aero TT, but the attempt was called off due to bad weather, and an effort the following day failed due to sub-optimal conditions, with test driver Rick Doria reporting wheelspin at speeds above Template:Cvt.[20]
Six months later SSC announced they had established a new production car speed record of Template:Convert in West Richland, Washington on September 13, 2007. In accordance with FIA Speed Records rules it was an average of two runs in opposite directions, Template:Convert and Template:Convert. The results were verified by the Guinness World Records on October 9, 2007. SSC is currently one of only twenty-six car manufacturers in history to have held the record.
SSC also applied to Guinness for the world record for the highest power for an emissions-legal production car.[21]
Its record was broken on July 4, 2010, by the Bugatti Veyron Super Sport, which reached a certified top speed of Template:Cvt.[22]
