A V12 engine is a V engine with 12 cylinder (engine)s in two banks. Like a straight-6, this configuration has perfect primary and secondary balance no matter which V angle is used and therefore needs no balance shafts.A V12 with two banks of six cylinders angled at 60° or 180° from each other has even firing with power pulses delivered twice as often per revolution as, and is smoother than a straight-6 because there is always even positive net torque output with little variation. This allows for great refinement in a luxury car; in a racing car, the rotating parts can be made much lighter and thus more responsive, since there is no need to use counterweights on the crankshaft as is needed in a 90° V8 and less need for the inertial mass in a flywheel to smooth out the power delivery. In a large, heavy-duty engine, a V12 can run slower than smaller engines, prolonging engine life.

Aviation V12 engines were first seen in aircraft. By the end of World War I, the V12 configuration was a fairly popular one in the newest and largest fighters and bombers; the engines were produced by companies such as Renault and Sunbeam (car). Many Zeppelins had twelve-cylinder engines, from German manufacturers Maybach and Daimler. Various US companies produced the Liberty L-12; the Curtiss NC Flying boats, such as the first aircraft to make a transatlantic flight, the NC-4, had a set of four V12 engines.

V12 engines reached their apogee during World War II. fighter aircrafts and bombers used V12 engines such as the British Rolls-Royce Limited Rolls-Royce Merlin and Rolls-Royce Griffon, the Soviet Klimov VK-107, the American Allison V-1710 engine or the German Daimler-Benz Daimler-Benz DB 600 series and Junkers (Aircraft)-Jumo. These engines generated about 1,000 horsepower (0.75 MW) at the beginning of the war and above 1,500 horsepower (1.12 MW) at their ultimate evolution stage. The German Daimler-Benz DB 605 engine reached 2000 hp (1.50 MW) with Water injection (engines). Their use disappeared quickly after the advent of the jet engine. In contrast to most Allied V12s, the motors built in Germany by Daimler-Benz and Junkers-Jumo were primarily inverted, which had the advantages of lower centers of gravity and improved visibility for single-engined designs.

The legendary Rolls-Royce Merlin V12 was particularly effective in the Hawker Hurricane and Supermarine Spitfire fighters that won the Battle of Britain and swept the German Luftwaffe from the skies of England. The long, narrow configuration of the V12 contributed to good aerodynamics, while its exceptional smoothness allowed its use with relatively light and fragile airframes. The Merlin was also used in the Avro Lancaster and de Havilland Mosquito bombers. In the United States the Packard Motor company was licensed by Rolls-Royce to produce the Packard Rolls-Royce Merlin#Packard's legacy for use in the North American P-51 Mustang. It was also incorporated into some models of the Curtiss P-40, specifically the P-40F and P-40L. Packard Merlins powered Canadian-built Hurricane, Lancaster and Mosquito aircraft, as well as UK-built Spitfires in the shape of the Mark XVI, otherwise the same as the Mark IX with its British-built Merlin.

The Allison V-1710 was the only indigenous United States-developed V-12 liquid-cooled engine to see service during World War II. A sturdy and trustworthy design, it unfortunately lacked an advanced mechanical supercharger until 1943. Although versions with a turbosupercharger did give excellent performance at high altitude in the Lockheed P-38 Lightning, the turbosupercharger and its ductwork were too bulky to fit into typical single seat fighters. While a superb performer at low altitudes, without adequete supercharging, the Allison's high altitude performance was lacking.

After WWII, V12 engines became generally obsolete in aircraft due to the introduction of turbojet and turboprop engines, which had more power for their weight, and fewer complications in large aircraft.

V12 road cars In automobiles, V12 engines have never been common due to their complexity and cost. They are used almost exclusively in expensive sports cars and luxury cars and are sought after for their power and relatively vibration-free operation.

Prior to World War II, twelve-cylinder engines were found in many luxury models, including cars from Auburn Automobile, Cadillac (automobile), Packard, Lincoln (automobile), Franklin (automobile), Rolls-Royce Limited, Pierce-Arrow, and Hispano-Suiza. Packard's 1912 "Double Six" is widely regarded as list of automotive superlatives production V12 engine. With its list price of US$1000, the Auburn was the cheapest V12 car ever; money was apparently saved by having its valves horizontal, which did not make for the most powerful combustion chamber. Between 1916 and 1921,Georgano, G.N. Cars: Early and Vintage, 1886-1930. (London: Grange-Universal, 1985). there was a vogue of V12s, during which National (Indianapolis) copied the Packard engine, and Weidely Motors (also of Indianapolis) offered a proprietary engine. Soon after the end of World War One, Lancia offered a 22ο V12, FIAT had a 60ο model (1921-2), and even British truck manufacturer Ensign promised one, which did not appear, and in 1926, Daimler (Britain) offered a sleeve-valve Double Six.Georgano. In 1927, there was a resurgence, and Daimler, Cadillac, Franklin (automobile), Hispano-Suiza, Horch, Lagonda, Maybach, Packard, Rolls, Tatra (car), Voisin, and Walter all had V12s, while Cadillac in 1930 (until 1940) and Marmon (from 1931-3) went up to V16s (a move reminiscent of the '60s "horsepower wars".)

Improvements in combustion chamber design and piston form enabled lighter V8 engines to surpass the V12 in power starting from the 1930s and they disappeared from the American market after WWII. Similarly, as they seemed excessive for the postwar market, their production lines were not restarted in European countries after the war and even through the 1960s.

Ferrari have traditionally reserved their top V12 engine for their top-of-the line luxury sports coupes since 1971. The next year, Jaguar Cars came out with the Jaguar XJ12.

German manufacturers Mercedes-Benz and BMW both returned to V12 designs in model year 1991 and 1986, respectively. The BMW-designed V12 also appears in Rolls-Royce Motors cars, while the Mercedes engine is also seen in Maybach cars. Aston Martin introduced a (Cosworth) V12 model in 2000, while Cadillac has contemplated re-introducing the V12 after 60 years with a version of their Cadillac Northstar engine.

In 1997, Toyota equipped their Toyota Century with a 5.0 L DOHC V12 (model # 1GZ-FE), making it the first and only Japanese production passenger car so equipped.

TVR made and tested a 7.7 L V12 called the TVR Speed Twelve engine, reportedly making 800+ BHP naturally aspirated, but the project was scrapped after the car it was designed for was deemed too powerful for practical use.

Heavy trucks Tatra cars uses a 17.6 L air-cooled turbocharger diesel engine V12 engine in many of their trucks, for instance the Tatra T813 and Tatra T815. Some trucks have been fitted with twin V12s.

GMC Truck produced a large gasoline-burning V12 from 1960 to 1965 for trucks, the "Twin-Six"; it was basically GMC's large-capacity truck 351 V6, doubled, with four rocker covers and four exhaust manifolds. 56 major parts are interchangeable between the Twin-Six and all other GMC V-6 engines to provide greater parts availability and standardization Its engine displacement was 702 in³ (11.5 L), and while Power (physics) was not too impressive at 250 SAE net horsepower (190 kW), torque was 585 lbf·ft (793 N·m). It was possibly the last gasoline engine used in heavy trucks in the United States.

Detroit Diesel produced their Series 53, 71, 92, and 149 engines as V-12's, among other configurations.

Auto racing V12 engines used to be common in Formula One and endurance racing. Between 1965 and 1980, Scuderia Ferrari, Weslake, Honda F1, BRM, Maserati, Matra, Alfa-Romeo, Lamborghini and Tecno used 12-cylinder engines in Formula One, either V12 or Flat-12, but the Ford Motor Company (Cosworth) V8 (engine) had a slightly better power-to-weight ratio and less fuel consumption, thus it was more successful despite being less powerful than the best V12s. During the same era, V12 engines were superior to V8s in endurance racing, reduced vibrations giving better reliability. In the 1990s, Renault F1 V10 engines proved their superiority against the Scuderia Ferrari and Honda F1 V12s and the Ford Motor Company V8. The last V12 engine in Formula One, was the Scuderia Ferrari 044, in the Ferrari cars driven by Jean Alesi and Gerhard Berger in 1995 Formula One season.

At the Mondial de l'Automobile 2006 Peugeot presented a new racing car, as well as a luxury sedan concept car, both called Peugeot 908 and fitted with a V12 Diesel engine producing around or even surpassing 700 DIN HP. This took part in the 24 Hours of Le Mans 2007 race, with a podium finish and very competitive performance.

Large diesel engines V12 is a common configuration for large diesel engines; most are available with differing numbers of cylinders in V configuration to offer a range of power ratings. Many diesel locomotives have V12 engines.

Mercedes (MTU) manufactured a line of V12 diesel engines for marine use. These engines commonly power craft up to about 100 tonnes in pairwise configurations and range in power from about 1 to 4 MW.

Tanks and other AFVs V12 is a common configuration for tank and other armoured fighting vehicles (AFVs). Some examples are: One such V12 Tank engine made its way into a Hot Rod style car called the Blastolene Special.
