Before the common combustion engine in the museum of thermal power drives joins the steam engine, we show it in its technical splendor and sculptural beauty – nine examples, from Alfa Romeo to Ferrari to Volvo.

Ferrari F140 GA – the monument
His sober name is Ferrari F140 GA. And if numbers and data bring you closer to the engine, here are a few: 6,496 cm3, 800 hp at 8,500 revolutions, maximum 718 Nm at 7,000. How this feels and sounds can be experienced in the Ferrari 812 Superfast. The base engine made its debut in 2002 in the Enzo with a displacement of 6 liters and 660 hp. The V12 inherited the exotic cylinder angle of 65 degrees from the Ferrari Formula 1 engines of the early 1990s. The slightly larger bench angle compared to the classic V12 has the advantage, among other things, that the intake system with steplessly variable nozzles fits well between the cylinder banks. The high-speed V12 (limit: 9,000 rpm) can deliver more than 80 percent of its maximum torque at 3,500 rpm. In addition, the resulting irregular firing interval creates the characteristic Ferrari V12 sound.
Mercedes M 256 48V – The electrified
With the M 256, a completely new generation of inline six-cylinder engines made its debut at Mercedes in 2017, a design that was actually already declared dead. Some advantages of the in-line six: Outstanding running culture through regular firing intervals and perfect mass balance. The M 256 has 2,999 cm3 and is designed with a long stroke of 83 mm and a stroke of 92.4 mm. The engine has some special features. In addition to an exhaust gas turbocharger, the engine has an additional electrical compressor that responds to gas commands before the exhaust gas turbine revs up. In addition, there is no belt drive for auxiliary units, the coolant pump and air conditioning compressor are supplied electrically by the integrated starter generator and the associated 48-volt electrical system. With 16 kW and 250 Nm, the starter generator can either push or recuperate as required.
