The SSC
Ultimate Aero is an
American-built mid-engine supercar by Shelby SuperCars. The higher-performance limited production
version previously held the Guinness Book of World
Records record
for being the fastest production car in the world (succeeded by the
2010 Bugatti Veyron Super
Sport), with a
recorded speed of 412.29 km/h (256.19 mph). This speed was achieved during
tests on September 13, 2007 West Richland,
Washington, United States and
verified by Guinness World Records on October 9, 2007. SSC contends that this speed
however does not reflect the SSC Ultimate Aero TT's
full potential. SSC estimates that the newer, more powerful and lighter weight
2009 Ultimate Aero TT is capable of a top speed of over 270 mph
(430 km/h). The SSC
Ultimate Aero does not have electronic aids such as ABS brakes or traction control, as according to Jerod Shelby; "Early
design philosophy on the car was to make it a drivers car. I wanted a car that
you not only throttled with your right foot but at times you could steer with
your right foot."
The Aero and the Shelby SuperCars company are the
brainchildren of Jerod Shelby (no relation to retired racing
driver and sportscar builder Carroll Shelby), who started out building exotic
"replicars" including a Fiero-based Ferrari F355 replica
and a Lamborghini Diabloreplica
based on a spaceframe which later was used in the Ultimate Aero prototype.
Jerod later moved from building replicas to designing his first Supercar and
after seven years it finally began to take shape. Although the basic Aero model
is no longer produced, the Ultimate Aero is still in production with an MSRP of
around $650,000.
Prototype (2004)
SSC Ultimate Aero SC/8T prototype #001 was built using a Lamborghini Diablo Replicar chassis with
twin turbocharged engine sourced from the Corvette C5R mated to a G-64 6-speed
manual transmission (also seen in the Dodge Viper). It weighs
2,800 pounds (1,270 kg). 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 McLaren F1 and Enzo Ferrari. Carbon fiber and titanium are
used throughout the car, helping to limit the weight to 1,293 kilograms
(2,850 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.
The engine in the base Aero model was a Supercharged V8 Chevrolet Small Block series engine rated at 1,077 PS (792 kW; 1,062 hp) at 6600 rpm and 1,357 N·m (1,001 ft·lbf) at 5800 rpm, with the supercharger at 8 psi (0.55 bar) and running on 91 octane gasoline. The Ultimate Aero has increased engine displacement of 6.34 L (387 cu in) and increased boost of 14 psi (0.97 bar), resulting in 1,203 PS (885 kW; 1,187 hp) at 6950 rpm and 1,113 N·m (821 ft·lbf) at 6200 rpm, running on 91 octane gasoline.[8]
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) at the car's redline. The base Aero, however, should "only" reach
about 380 km/h (236 mph). The Ultimate Aero accelerates from 0–96 km/h
in 2.78 seconds, slower
than the Bugatti Veyron which
achieves 0–96 km/h in 2.46 seconds partially due to its AWD drivetrain.
But the Aero does out-perform the famous Bugatti in a quarter-mile drag race,
and surprisingly outhandles its more modern competition in both skid pad
G-force and slalom tests.
Specifications (2007)
The engine in the base Aero model is the same as the previous
year, but the Ultimate Aero has a 6.35 litres (388 cu in) engine,
rated at 1,199 PS (882 kW; 1,183 hp) at 6950 rpm and 1,483
newton metres (1,094 ft·lbf) 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 Petrol. 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 (2,850 lb), and Ultimate version 1,250 kilograms
(2,800 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$285,000. 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.
Specifications (2008)
In 2008 models of Ultimate Aero, 4 changes were made:
§
New
Twin-Turbo V8
§
All new
aluminum engine block
§
Standard
HRE Monoblok wheels
Specifications (2009)
The new Ultimate Aero has 15% more power, resulting in
1,287 hp (960 kW; 1,305 PS) at 6075 rpm 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 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 to slow the vehicle.

Ultimate Aero EV
SSC announced the
production of the Ultimate Aero EV, an electrical version of the sports car.
The released specifications include using 500 hp(373 kW) electric
motor, with SSC also exploring the potential of using 2 engines in 2 or 4 wheel
drive configuration. "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.
SSC announced electric powertrain and Ultimate Aero EV
specifications. "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 (746 kW) and 800 lb·ft (1,100 N·m) of torque
enabling it to rocket to 60 mph (97 km/h) in a mere 2.5 seconds and
reach a top speed of 208 mph (335 km/h). Not only does the Ultimate
Aero EV have a range of 150–200 miles on a single charge, but SSC's
"Charge on the Run" 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
253.7 mph (408.3 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). 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). Despite the failure of the attempt, the car
still reached 389 km/h (242 mph).
SSC announced they had broken the speed record for the
world's fastest production car with 412.28 km/h (256.18 mph) 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 FIA Speed Records rules. The first
run clocked 414.31 km/h (257.44 mph) and the return trip
410.24 km/h (254.91 mph). 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 412.28 km/h (256.18 mph). This beat the previous record holder, the Bugatti Veyron, that had 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 power for an emissions-legal
production automobile.
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.
The car's record was broken on July 4, 2010 by the Bugatti Veyron Super
Sport, which reached a certified top speed of 431.072 km/h
(267.86 mph).
On July 17th 2011, it was announced the successor to the
Ultimate Aero would be named the Tuatara.
