SSC Ultimate Aero


The SSC Ultimate Aero is a mid-engined sports car that was produced by SSC North America from 2004 until 2013. The SSC Ultimate Aero held the world production car speed record title, according to the Guinness World Records, from 2007 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.
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, "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

The first SSC Aero prototype was completed in 2004 and began road testing in anticipation of the SSC Ultimate Aero production vehicle.
Specifications:
  • Engine - Supercharged LS1-based V8
  • Power - at 6,600 rpm
  • Torque - at 5,800 rpm
  • Redline - 7200 rpm
  • Top speed -
  • Dry weight -

    SSC Ultimate Aero SC/8T Number 2 (2005)

testing indicated that the Ultimate Aero could theoretically reach a top speed of given appropriate transmission gear ratios, although the supplied transmission would result in at the car's redline. The base Aero, however, had a theoretical top speed of about. The Ultimate Aero accelerates from 0– in 2.78 seconds, slower than the Bugatti Veyron which achieves 0–100 km/h in 2.46 seconds, partially due to its AWD drivetrain.
Specifications:
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 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.
Specifications:
  • Engine: supercharged 6,300 cc Chevrolet Corvette C5-R V8
  • Power: at 6950 rpm
  • Torque: at 6200 rpm
  • Redline: 7200 rpm
  • Top speed:
  • Dry weight:

    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 at 7200 rpm. Wheels on the base model are sized at the front and 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, and Ultimate version. 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$285,000. 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 in Washington. 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
Specifications:
  • Engine - twin-turbocharged 6,300 cc bored-out LS6
  • Power - at 6950 rpm
  • Torque - at 6150 rpm
  • Redline - 7200 rpm
  • Top speed -
  • Dry weight -

    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 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 when the brake is pressed. This updated model reached a top speed of in a test, according to SSC.
Specifications:
  • Engine: twin-turbocharged 6,300 cc SSC V8
  • Power: at 6100 rpm
  • Torque: at 6100 rpm
  • Redline: 7200 rpm
  • Top speed:
  • Dry weight:
A 2009 SSC Ultimate Aero, albeit with the new prototype SSC Tuatara gearbox fitted, was able to complete six runs of 0– from 15.1 to 15.8 seconds, according to SSC's gear ratio testing results.

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 and of torque through a three-speed automatic transmission. SSC claimed that the car would be able to accelerate from 0– in 2.5 seconds, and reach a top speed of. 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.
Specifications
  • Engine: twin-turbocharged 6,900 cc SSC V8

  • Torque: at 6800 rpm
  • Redline: 9100 rpm
  • Top speed -
  • Top speed :
  • Drag coefficient:

    Speed record

Simulation and testing at NASA's Langley Research Center had shown the Ultimate Aero TT theoretically capable of attaining about, sufficient to surpass the production car record-holding Bugatti Veyron's.
A 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.
Six months later SSC announced they had established a new production car speed record of 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, and. 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.
Its record was broken on July 4, 2010, by the Bugatti Veyron Super Sport, which reached a certified top speed of.
