The first production car to use a V16 engine was the [[Cadillac V-16]], introduced in January 1930. The [[Cadillac V16 engine]] was initially produced with a displacement of {{convert|452|cuin|L|1|abbr=on}}, [[overhead valve engine|OHV]] and a V-angle of 45 degrees. For the 1938 [[Cadillac V16#1938–1940|Series 90]], the engine was revised to a displacement of {{convert|431|cuin|1|abbr=on}}, a [[flathead engine|flathead valvetrain]] and a V-angle of 135 degrees (the latter in order to achieve a lower cowl height). This 431&nbsp;cu. in. version produced as much power as its immediate predecessor while being far less complex, had a stiffer crankshaft that aided durability and smoothness, and even had an external oil filter, a rarity for any car at any price in those days.

The [[Marmon Motor Car Company]] actually began development of a V16 engine in 1927 (earlier than Cadillac). Its development program took longer, however, and the ''Marmon Sixteen'' was released in 1931. This engine had a V-angle of 45 degrees, used pressed steel [[cylinder liner]]s and was constructed mostly of aluminum. Only 400 Marmon Sixteens were produced between 1931 and 1933. 
In 1991, the [[Cizeta-Moroder V16T]] began production, featuring a 16-cylinder engine in a unique configuration. Rather than a conventional V16 layout, the engine was actually two separate sets of [[transverse engine|transversely mounted]] V8 cylinders in a single block with gearing between the two sets providing a single output from the center of the engine to the transmission. Only a few cars were produced before the company ceased operations. In June 2024, Bugatti unveiled the [[Bugatti Tourbillon|Tourbillon]], the successor to the [[Bugatti Chiron|Chiron]], marking a modern revival of the V16 configuration.<ref>{{Cite web |last=Communications |first=Bugatti |date=2025-04-24 |title=Silence to Symphony: The Birth of Bugatti’s new Mechanical Heart – Bugatti Newsroom |url=https://newsroom.bugatti.com/press-releases/silence-to-symphony |access-date=2025-05-08 |website=newsroom.bugatti.com |language=en}}</ref> The Tourbillon features an 8.3L (506 cu in) naturally aspirated V16 engine co-developed with [[Cosworth]]. Weighing just 252 kg in total–lighter than the naturally aspirated [[Aston Martin]] 6.0- litre V12-the engine incorporates titanium connecting rods and a carbon fibre inlet plenum to minimize weight. Paired with three electric motors, the hybrid system delivers a combined 1,800 horsepower, enabling the car to accelerate from 0 to 100km/h in just 2.0 seconds. <ref>{{Cite web |title=Cosworth’s most powerful naturally aspirated hypercar engine unleashed |url=https://www.cosworth.com/news/cosworth-s-most-powerful-naturally-aspirated-hypercar-engine-unleashed/ |access-date=2025-05-08 |website=www.cosworth.com |language=en}}</ref>
