I would have to drive both because the 300 is a 2L with a massive turbo and as good as they might be in the car range the V-class is a much heavy vehicle, this requires torque rather than a short mind blowing power band ripping up through the 9speed gearbox.
It all sounds rather odd to me, fantastic in a sporty car but how does that translate to a camper van.
The 220 drives well, by all accounts the 250 hasn’t upset anyone so it’s probably safe to say the 300 is going to be fine, by all accounts it’s a much quieter engine and better refined my concern is related to just how busy is it going to be trying to match the narrow power band with one of those 9 gears.
I should just book a test drive.
