SSC Ultimate Aero TT

The SSC Aero is an American-built mid-engine sports car by Shelby SuperCars. Its higher-performance limited production version, the SSC Ultimate Aero TT,is currently the fastest production car in the world, with a fastest recorded speed of 413 km/h (257 mph).This speed was reportedly achieved during tests on September 13, 2007 in West Richland, Washington, United States and verified by Guinness World Records on October 9, 2007.
The Aero and the Shelby SuperCars company are the brainchildren of Jerod Shelby, who spent over seven years designing the car. The basic Aero model is no longer produced, while, as of 2008, the Ultimate Aero costs about 620,000 dollars.

Specifications (2006)

Styling of the Aero includes the use of butterfly doors similar to those found on the SLR McLaren, Saleen S7, Mercedes-Benz CLK-GTR, and the Enzo Ferrari. Carbon fiber and titanium are used throughout the car, helping to limit the weight to 2,850 lb (1,293 kg) 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 is a supercharged 382 cu in (6.26 L) V8 engine rated at 1,062 hp (792 kW) at 6600 rpm and 1,001 ft·lbf (1,357 N·m) at 5800 rpm, with the supercharger at 8 psi and running on 91 octane gasoline. The Ultimate Aero has increased engine displacement of 387 cu in (6.34 L) and increased boost of 14 psi, resulting in 1,046 hp (780 kW) at 6950 rpm and 821 ft·lbf (1,113 N·m) at 6200 rpm, running on 91 octane gasoline.
Wind tunnel testing indicates that the Ultimate Aero could theoretically reach a top speed of 273 mph (439 km/h) given appropriate transmission gear ratios, although the supplied transmission would result in 259.8 mph (418 km/h) at the car's redline. The base Aero, however, should "only" reach about 236 mph (380 km/h). The Ultimate Aero accelerates from 0-60 mph in 2.78 seconds, slower than the Bugatti Veyron which achieves 0-60 mph in 2.46 seconds.

Specifications (2007)

The engine in the base Aero model is same as the previous year, but the Ultimate Aero has a 6.35-litre (387.2 cu in) engine, rated at 1,183 bhp (882 kW) at 6950 rpm and 1,094 lb·ft (1,483 N·m) 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.The 6-speed transmission is readjusted to increase the theoretical top speed to 273.75 mph (437 km/h) at 7200 rpm, however whether the vehicle is able to reach this speed is highly questionable and has never been tested.
Wheels on the base model are sized 18-inch (460 mm) at the front and 19-inch (480 mm) 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 2,850 lb (1,290 kg), and Ultimate version 2,750 lb (1,250 kg). 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.

Specifications (2008)

In 2008 models of Ultimate Aero, 3 changes were made:
All new aluminum engine block
Standard HREbe geared for 458 km/h (284.60 mph) but whether the car can reach this speed has yet to be tested
