Lewis Hamilton says the new power unit of Mercedes for the Belgian Grand Prix will only bring a small performance gain and is mainly intended to improve efficiency.
The new power Unit will be raced by all three Mercedes-powered teams including Racing Point and Williams.
“It’s pretty much the same as the second one,” said Hamilton. “So not really any real improvements.
“We’ve constantly been at the forefront of the technology on the engine side. There have been years when we’re just constantly ramping up, ramping up. But when you’re constantly the leader it’s not always easy to keep leading, you have rougher patches. I think it’s been a bit of a harder year in terms of development.
“But we’ve still got great reliability. The last race I did on my first engine and my engine was fantastic throughout the race. So I think this next one it’s the smallest of steps. Not even half a tenth, probably. But I think it’s more reliability continues to improve. Efficiency, which is something we’re really focused on, I think efficiency is key.”
