The 2009–2018 presidential state car went into service on January 20, 2009 and drove President Obama the two miles (3.2 km) down Pennsylvania Avenue from his inauguration to the inaugural parade.
 A Cadillac, the presidential state car was not based on any single model of car, though it had the "dual-textured grille and the dinner plate-sized Cadillac coat-of-arms badge" emblematic of the Cadillac CTS and the Cadillac Escalade.
 The headlights and taillights were identical to those used on other Cadillac production models.
 Anton Goodwin of CNET's Road/Show blog noted that speculation was that the presidential state car was based on the GMC Topkick platform.
 If that is to be the case, then Goodwin assumed the car would feature either a gasoline-powered Vortec 8.1-litre (490 cu in) V8 engine or a diesel-powered Duramax 6.6-litre (400 cu in) turbo V8 engine.
 Autoweek magazine asserted that the car ran on a gasoline-fueled engine.
 The Obama/Trump presidential state car was speculated to be much heavier than its predecessor as it is equipped with Goodyear Regional RHS tires that are usually reserved for medium- and heavy-duty trucks; speculated weights range from 15,000 to 20,000 pounds (6,800 to 9,100 kg).
 Due to the weight of the car, it could only reach about 60 mph (97 km/h), and only achieved 3.7 to 8 miles per US gallon (64 to 29 L/100 km; 4.4 to 9.6 mpg‑imp).
 The limousine was reported to cost between US$300,000 and US$1,500,000 (equivalent to about US$400,000–1,600,000 in 2019).
 The presidential state car was maintained by the United States Secret Service.

The doors had no keyholes; the way to open the passenger doors on the limousine is a secret known only to the Secret Service.
 It had more five-inch-thick (13 cm) bulletproof glass than the previous model.
 It also had run-flat tires and an interior that was completely sealed to protect the occupants in the event of a chemical attack.
 The 2009 presidential state car model had night vision optics, a tear gas cannon, onboard oxygen tanks, an armored fuel tank filled with foam to prevent explosion, and pump-action shotguns.
 Whether it was or was not armed with rocket-propelled grenades, the car could fire "multi-spectrum infrared smoke grenades as a counter-measure to a rocket-propelled grenade attack or anti-tank missiles."
 The car featured eight-inch-thick (20 cm) doors.
 General Motors spokeswoman Joanne K. Krell said of the presidential state car, "The presidential vehicle is built to precise and special specifications, undergoes extreme testing and development, and also incorporates many of the top aspects of Cadillac's 'regular' cars—such as signature design, hand-cut-and-sewn interiors, etc."

In 2013, the presidential state car was outfitted with standard Washington, D.C. license plates that read "TAXATION WITHOUT REPRESENTATION" in reference to the district's lack of representation in the United States Congress.
 The switch came after the D.C. city council petitioned the president to use the plates on his motorcade, which would be seen by millions of people as the president heads down Pennsylvania Avenue for his second inauguration.
