While the car’s engine is often referred to as a flat-12, it is technically correct to call it a V12. Although the pistons in the Testarossa’s 12-cylinder are horizontally opposed, the engine isn’t what the automotive world classifies as a flat or boxer engine. The Ferrari ‘flat-12’ is actually a 180-degree V12.

In an informative video, DriveTribe’s softy-spoken Mike Fernie explains that, despite Ferrari calling the Tipo F113 engine in the back of its Testarossa a flat-12 (and later naming the 365 GT4 and 512, which share this powertrain, Berlinetta Boxers), the engine is actually neither a flat-12, nor a boxer.

The 512 TR sports a 4.9-litre (4.943 L (4,943 cc)) longitudinally rear-mounted flat-12 engine, with a maximum power output of 319 kW (434 PS; 428 hp) at 6,750 rpm. Have another FAQ about the Ferrari 512 TR?…Model years for Ferrari 512 TR (1991 to 1996)

Ferrari’s mid-engined, flat-12 Testarossa was unveiled to an expectant media at the Champs Elysees Lido nightclub on the eve of the 1984 Paris Salon….Detailing.

In addition to that six cylinders in a row can be balanced perfectly, better than 4 cylinders in a row. That is the reason that many luxury sedans rely on V12 engines – they run significantly smoother than V8 engines. On the other hand a V8 engine is simpler, lighter and has a better efficiency (less moving parts).

For Ferrari’s V12 engines, a flat plane crank is not possible, but they use a configuration that gives a similar firing pattern. Ferrari’s V12s can have larger displacements, around 6.0-liters, because each individual piston stays small. V12 Engine. The number of cylinders makes a big difference in the sound as well.

Boxer engines are a type of flat engine; however, flat engines are not necessarily boxer engines. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks. Each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward.

Production cars From 1973-1996, Ferrari used flat-twelve engines in various production models: the 1973-1976 Ferrari 365 GT/4 BB, the 1976-1981 Ferrari BB 512, the 1981-1984 Ferrari BB 512i, the 1984-1991 Ferrari Testarossa, the 1991-1994 Ferrari 512 TR and the 1994-1996 Ferrrari F512 M.

Large V12 diesel engines are common modern cruise ships, which may have up to six such engines. An example of a currently produced V12 marine engine is the Wärtsilä 46F engine, where the V12 version has a displacement of 1,157 L (70,604 cu in) and a power output of 14,400 kW (19,300 hp).

The inline-four engine is the most common four-cylinder configuration, whereas the straight-6 has largely given way to the V6 engine, which although not as naturally smooth-running is smaller in both length and height and easier to fit into the engine bay of smaller modern cars.
