The benefits of Formula 1 racing were thought to be exclusive to Europeans, whose vehicles have been developing along with the motorsports championship since 1950. However, Koreans can now enjoy the same benefits as Europeans with Renault Korea Motors' SM6.
The carmaker's new SM6 TCe 300 sedan is equipped with the same engine that is used in the Alpine and Renault R.S. models. The engine creates a maximum output of 225 horsepower and torque of 30.6 kilogram-meters with 1,798 cubic centimeters of displacement. Its torque reaches the highest level in the wide range of 2,000 revolutions per minute (RPM) to 4,800 RPM. This is equivalent to the performance of a 3.5-liter naturally aspirated engine.
The twin scroll turbocharger technology of the TCe 300 engine minimizes turbo lag and exhaust pressure loss, resulting in immediate acceleration. This is the principle of quickly turning the turbocharger by separately configuring the exhaust passage of the cylinder to suppress exhaust interference.
In fact, Renault's turbo engine is an F1 racing legend.
When Renault first jumped into the F1 in 1977, all carmakers used a 3.0-liter naturally aspirated engine. Renault joined the race with a V6 1.5-liter turbo engine (EF-Type).
Back then, the F1 rule allowed either a 3.0-liter naturally aspirated engine or a 1.5-liter supercharger or turbocharged engine. Renault's choice of the turbo engine was a bold and surprising decision that is still talked about today.
Renault It successfully overcame turbo lag with two small turbochargers, which led to its first F1 victory in 1979 and opened the era of the turbo engine.
By 1985, all carmakers adopted turbo engines for their F1 racers.
