- Report: It Looks Like Volvo is Working on a TCR Race Car
It’s become such a popular rallying cry that it’s almost a cliché now, but turbo lag is one of the great sins of our time—and the cardinal sin of years gone by. Now, though, Volvo is fighting back like a paladin riding on the wings of electrification as this video by popular YouTuber Jason Fenske explains.
There are a number of ways to fight turbo lag, and Volvo has two big ones. The first is surprisingly low tech, but also deliciously Rube Goldbergian since it involves filling a high-pressure air tank with compressed air that’s then shot at the turbo fans when you matt the accelerator.
By spinning up the turbo (the first of two turbos), Volvo shrinks the spool time and gets the turbo working faster.
This system is mainly available on diesels, though. The second system you can actually see right now, on Volvo’s T8 twin-engine powered cars.
This system effectively throws every possible solution at the problem, taking advantage of a supercharger’s inherent low lag, then adding an electric motor to get even more low-down torque to the wheels.
When you add it all up, you get a car with virtually no lag between pressing the pedal and making the scenery melt past your windows.
