How does the 1.3 MultiJet respond?
It is a small-displacement engine, so the relative gain in flexibility is noticeable, particularly when the car is loaded.
What is the 0.9 TwinAir?
It is the group's turbocharged two-cylinder petrol, an unusual design. It responds well to a measured map given how small it is.
Is a remap worthwhile on an MPV?
Yes, especially if the car is regularly full. The extra mid-range torque is most noticeable with a full load on board.
