One of the earliest V4 internal combustion engines was that designed by Émile Mors of Paris to power his motor-car of 1897. The 90 degree V-angle with central camshaft and spark ignition meant its layout is much like more modern engines, though in this case the inlet valves were operated by suction alone. At the time the lack of vibration from this layout was a key selling point.
The V4 engine has not been widely used in cars, with Lancia, Ford and ZAZ the only companies to manufacture such an engine.
- The British Ford Essex V4 engine
- The German Ford Taunus V4 engine (also used by Saab, the Matra 530 and in the 1962 Ford Mustang I rear-engine concept roadster)
In the 1930 Matchless Silver Hawk used a narrow-angle V4, while Puch used a very wide-angle V4. V4 engines are more recently found in motorcycles, typically transversely mounted. This engine design enjoyed particular popularity during the mid-to-late 1980s. Models with V4 engines include:
- Aprilia RSV4

- Yamaha Venture and Venture Royale

Wisconsin Motors produced an air-cooled V4 engine that is used in various industrial, agricultural, and stationary applications. Farm equipment Manufacturers liked to use the Wisconsin V4s due to their compact size and power output.
Another use of the V4 engine is in outboard motors. They are two-stroke cycle and generally carbureted. Some of the largest manufacturers are Johnson, Evinrude and Yamaha. This type of engine is popular because of its small size, while still producing 140 hp (104 kW), or more.
