The turbocharger vs supercharger debate continues to divide people into two groups of forced induction preference. There are those who still prefer the high rev, exhaust gas process and the lower rev, stable crankshaft crowd. The latest at the Volvo engine plant in Skövde gives us something new to talk about on this front.
Volvo has had its fair share of issues, but their re-engineered 4, 5, and 6-cylinder powerplants are not one of the problems. In fact the brand continues to invest in an on-going modernization effort. What brings turbocharging and supercharging together is their 2.0-liter inline 4-cylinder T6 engine. They are not the first ones to bring these together, but they feel they addressed difficult issues successfully. Derek Crabb, their VP of Powertrain Development, told Popular Mechanics that “the big issue was getting them to work together with refinement. The units themselves are simple,” he adds, “but control, refinement, and noise/vibration/harshness was where the big challenge was.”
The combo may not be new, but Volvo claims this to be the first in its class to deliver over 2 horsepower per gram of CO2 emissions, the T6 churns 302 horsepower, 295 lb-ft of torque, and a nice fuel economy rating of 24 mpg city, 35 mpg highway for a 0 to 60 mph time of 5.6 seconds.
What are your thoughts on turbochargers vs. superchargers or celebrating the combination?
