The Aston Martin DBR9 is a racing car by Aston Martin Racing, first built in 2005. The name DBR9 is derived from the original 24 Hours of Le Mans-winning DBR1 car, named for then-owner David Brown, which not only won the 24 Hour race in 1959 but also the World Sportscar title.

Based on the Aston Martin DB9 road car, the DBR9 retains the chassis, and the engine block and cylinder heads of the road car's V12 engine. The rest of the car is re-engineered for high performance competition use. The DBR9's bodywork is a blend of optimum aerodynamic performance and the styling of the DB9 road car. All the body panels are constructed from carbon fibre composite (except the roof) to minimize the weight of the car. To complete the aerodynamic body, the bottom of the car is flat all the way from the front to the rear diffuser. To optimise rear downforce a carbon fibre wing has been added. The car goes from 0-60 mph in 3.4 seconds.

For the 2007 24 Hours of Le Mans, Prodrive made modifications to the DBR9 design in order to not only improve performance, but also to increase driver comfort in the cockpit. Due to new regulations put into place by Le Mans organizers, the DBR9 required the installation of an air conditioning unit in order to prevent overstressing drivers. Prodrive went further by putting a heat-resistant white roof on all new cars to assist in keeping cockpit temperatures down. Performance modifications included the removal of two cooling vents from the bonnet of the car due to no longer being necessary.

The Ford GT features many new and unique technologies, including super-plastic-formed aluminum body panels, roll-bonded floor panels, a friction-stir welded center tunnel, a “ship-in-a-bottle” gas tank, a capless fuel filler system, one-piece door panels and an aluminum engine cover with a one-piece carbon-fiber inner panel.

Brakes are four-piston aluminum Brembo calipers with cross-drilled and vented rotors at all four corners. When the rear canopy is opened, the rear suspension components and engine are visible.

The 5.4L Modular V8 powerplant is all-aluminum and fed by a Lysholm twin screw-type supercharger. It features a forged rotating assembly housed in an aluminum block designed specifically for the GT program. A dry sump oiling system is employed, allowing the engine to sit very low in the frame. The DOHC 4-valve heads are a revision of the 2000 Ford Mustang SVT Cobra R cylinder heads (with slightly increased wall casting thickness in the exhaust port). The camshafts have unique specifications, with more lift and duration than those found in the Shelby GT500 or 2003–2004 Ford Mustang SVT Cobra. Power output is 550 horsepower (410 kW) and 500 foot-pounds force (680 N·m) of torque. A Ricardo six-speed manual transmission is fitted featuring a helical limited-slip differential.

Performance:

* 0–60 mph (0–96 km/h): 3.3 seconds
* 0–100 mph (0–160 km/h): 7.4 seconds
* Standing 1/4 mile: 11.2 seconds @ 131.2 mph (211.1 km/h)
* Top speed: 205 mph (electronically limited)

The Ford GT is a mid-engined supercar. It was built by Ford Motor Company from 2003 to 2006. It began as a concept car designed in anticipation of Ford's centennial year and as part of its drive to showcase and revive its "heritage" names such as Mustang and Thunderbird. Camilo Pardo, the head of Ford's "Living Legends" studio, is credited as the chief designer of the GT and worked under the guidance of J Mays. The designers drew inspiration from Ford's classic GT40 race cars of the 1960s and the GT is sometimes mistaken for its 1960s counterpart.

Positive response on the auto show circuit in 2002 helped persuade the company to produce the car in limited quantities, and the first production versions appeared in 2005. It is a very high-performance, two-seater vehicle with a strong styling resemblance to its racing ancestor and performance to match. The powerplant is a mid-mounted supercharged 5.4 litre V8, producing 550 horsepower (410 kW) and 500 foot-pounds force (680 N·m). Top speed is 212 mph (341 km/h).
