Valtteri echoed his team-mate's confidence in the trusty steed that is his first Power Unit of the 2018 season and looked ahead to the prospect of unleashing the next generation when the time comes.
"We were initially expecting to bring the new Power Units to this race, which would have been a small gain compared to the old one," he explained. "We found some issues so, just to be safe, we need to make it perfect and hopefully run it in two weeks.
"For sure, the new one would have been a little bit better - but it's not like our old engine, the phase one, is a bad engine. It's a good one and it's still healthy. It's been reliable, so no concerns on that.
"We're also planning to use it again later this year in Budapest - but now, instead of that, we're going to use the new one in Budapest, so I think it's going to be a small penalty. Obviously, it would have been nice but that's how it is."
