What is the cause of turbo lag in the BMW M4?

I recently test drove a BMW M4 and noticed significant turbo lag when accelerating. Can you explain why this is happening? Is there a way to minimize its effect?

Hi Samantha, turbo lag in the BMW M4 is caused by the time it takes for the turbocharger to reach its optimal speed and deliver increased power. This can be minimized by keeping the engine revs higher and shifting at higher RPMs. Additionally, a performance-tuned ECU can also help reduce turbo lag.

Hey Samantha, turbo lag is a common issue with turbocharged engines and can be improved by upgrading to a higher quality turbos or installing an aftermarket boost controller. Additionally, proper maintenance and regular oil changes can also help minimize turbo lag.
