The SSC Ultimate Aero is a mid-engined sports car that was produced by SSC North America (formerly known as Shelby SuperCars) from 2006 until 2013. The SSC Ultimate Aero held the title of the fastest production car in the world, according to the Guinness World Records, from 2007 (when it was officially timed at 256.14 mph (412.22 km/h)) until the introduction of the Bugatti Veyron Super Sport in 2010. However, 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, thereby reinstating the Ultimate Aero as the fastest production car in the interim.[2]

The SSC Ultimate Aero was not sold with electronic driver aids such as antilock brakes or traction control, 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 "

Development history

1998 - Company Founded

Jerod Shelby founded SSC in 1998 and began working on the company's first prototype vehicle

2004 - SSC Aero SC/8T №1

The first SSC Aero prototype was completed in 2004 and began road testing in anticipation of the SSC Ultimate Aero production vehicle.

Technical specification

  • Engine - Supercharged 377.6 cu in (6,188 cc) Chevrolet Corvette C5R V8[3]
  • Horsepower - Initially 782 hp (583 kW; 793 PS) @ 6600 rpm as built in 2004. 908 hp (677 kW; 921 PS) @ 6600 rpm after 2005 upgrade.[4]
  • Torque - 860 N⋅m (634 lb⋅ft; 88 kg⋅m) @ 5800 rpm as built in 2004. 1,045 N⋅m (771 lb⋅ft; 107 kg⋅m) @ 5800 rpm after 2005 upgrade.[3]
  • Redline - 7200 rpm
  • Max Speed - 380 km/h (236 mph) as built in 2004. 390 km/h (242 mph) after 2005 upgrade.[citation needed]
  • Dry Weight - 2,720 lb (1,234 kg)[4]

2005 - SSC Ultimate Aero SC/8T №2

Wind tunnel testing indicated 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) at the car's redline.[5] The base Aero, however, had a theoretical top speed of about 380 km/h (236 mph).[6] The Ultimate Aero accelerates from 0–96 km/h in 2.78 seconds,[7] slower than the Bugatti Veyron which achieves 0–96 km/h in 2.46 seconds partially due to its AWD drivetrain.[8]

Technical specification

2006

Styling of the Aero includes the use of butterfly doors similar to those found on the McLaren F1 and Enzo Ferrari. 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. The SSC Ultimate Aero was the final version of the prototype, introduced in 2006. It had an increased engine displacement of 387.2 cu in (6,345 cc) and increased boost of 14 psi (0.97 bar).

Technical specification (Ultimate Aero)

2007–2008

The Ultimate Aero TT was a twin-turbocharged version of the Ultimate Aero. The 6-speed transmission is readjusted to increase the theoretical top speed to 437 km/h (272 mph) at 7200 rpm. Wheels on the base model are sized 460-millimetre (18.1 in) at the front and 480-millimetre (18.9 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 kg (2,851 lb), and Ultimate version 1,250 kg (2,756 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.[citation needed] Later cars are expected to cost US$285,000.[9] Only 24 Ultimate Aero TTs were produced from 2006-2007. The Ultimate Aero TT made its international debut on the International Show Circuit in November 2006. The Ultimate Aero TT claimed the Guinness World Record for the fastest production car, after it was officially timed at 256.14 mph (412 km/h) in Washington.[10] For 2008, the Ultimate Aero received four updates:

  • New Twin-Turbo V8
  • All new aluminum engine block
  • Standard HRE Monoblok wheels
  • Azentek Atlas computer infotainment system[11]

Technical specification (2007 Ultimate Aero TT)

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 270 mph (430 km/h) is possible. In order to prevent the engine from overheating, airflow to the engine has been 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 in (203.2 mm) when the brake is pressed.[12] This updated model reached a top speed of 257.41 mph (414.26 km/h) in a test, according to SSC.[13]

Technical specification (2009 Ultimate Aero TT)

  • Engine - Twin-turbocharged 387.2 cu in (6,345 cc) SSC V8[13]
  • Horsepower - 1,287 bhp (960 kW; 1,305 PS) @ 6075 rpm[13]
  • Torque - 1,112 lb⋅ft (1,508 N⋅m; 154 kg⋅m) @ 6150 rpm[13]
  • Redline - 7200 rpm[13]
  • Max Speed - 257.41 mph (414.26 km/h)[13]
  • Dry Weight - 2,750 lb (1,247 kg)[13]
  • Length - 176.2 in (4,475.5 mm)[13]
  • A 2009 SSC Ultimate Aero, albeit with the new prototype SSC Tuatara gearbox fitted, was able to complete six runs of 0-200 mph in under 16 seconds, (15.1s - 15.8s) 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 1,000 hp (746 kW; 1,014 PS), and 800 lb⋅ft (1,085 N⋅m; 111 kg⋅m) of torque, which was transmitted through a three-speed automatic transmission.[15] SSC claimed that the car would be able to accelerate from 0–60 mph (0–97 km/h) in 2.5 seconds, and reach a top speed of 208 mph (335 km/h).[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. Only five XTs were built, and they utilized 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-aluminum twin-turbo V8 engine and a seven-speed paddle-shifted gearbox.[16]

Technical specification (Ultimate Aero XT)

(official manufacturer numbers)

  • Engine - Twin-turbocharged 423.6 cu in (6,942 cc) SSC V8[17]
  • Horsepower - 1,300 bhp (969 kW; 1,318 PS) @ 6800 rpm[17]
  • Torque - 1,004 lb⋅ft (1,361 N⋅m; 139 kg⋅m) @ 6800 rpm[17]
  • Redline - 9200 rpm[17]
  • Max Speed (theoretical)[17] - 273 mph (439 km/h)
  • Max Speed (actual) - 256 mph (412 km/h)
  • Drag Coefficient - 0.357[17]
  • Dry Weight - 2,800 lb (1,270 kg)[17]
  • Curb weight - 2,850 lb (1,293 kg)[18]

Speed record

Simulation and testing at NASA's Virginia facility had shown the Ultimate Aero TT theoretically capable of attaining approximately 273 mph (439 km/h),[19] sufficient to surpass the production car record-holding Bugatti Veyron's 253.7 mph (408.3 km/h).

A 12-mile (19 km) stretch of U.S. Route 93 in Nevada 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 wheel-spin at speeds above 190 mph (306 km/h).[20]

Six months later SSC announced they had established a new production car speed record of 256.18 mph (412.28 km/h) in West Richland, WA on September 13, 2007. In accordance with FIA Speed Records rules it was an average of two runs in opposite directions, 257.44 mph (414.31 km/h) and 254.91 mph (410.24 km/h). The results were verified by the Guinness World Records on October 9, 2007. SSC is currently one of only 26 automobile 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 automobile.[21]

Its record was broken on July 4, 2010 by the Bugatti Veyron Super Sport, which reached a certified top speed of 431.00 km/h (267.81 mph).[22]
