“This upgrade will not be as big as the tool that we delivered last year in Austria and Singapore, but it should be a decent step.
“It should be noticeable. I can’t say much more than that because otherwise, we talk about numbers that we’d like to keep confidential.
“But let’s say not as big, probably as Austria in Singapore, but noticeable if things correlate with our expectation with the wind tunnel numbers, for instance, and with the computer simulation.
“It’s always a big if because even if the hit rate of this correlation has been good over the last 12 months, there’s always possible surprises.”
