Of the team’s 151 Constructors points to date in 10 rounds this season, more than a third have been scored in the past two races.
“A really great weekend,” said Lewis.
“We are not there yet but we have taken a huge step,” he added.
George added: “As a team our aim was to maximise what we could achieve today, and we did that with P3 and P4.”
Good Friday to Solid Saturday
Lewis and George locked out the second row – the best team Quali result of the season.
A thousandth of a second kept George from P4 in Imola. It was the same story a week later in Monaco. Just two tenths left Lewis six places behind polesitter George in Montreal. But in Spain we were very much in the mix.
The hard yards were put in by reserve driver Fred Vesti in the Sim in Brackley on Friday, a fine effort considering just six days earlier he had driven 12 of the 24 hours for his team at Le Mans on his event debut.
“The recent steps we have taken with the car are clearly helping, and we are looking to build on that tomorrow,” said George.
“We are starting to be more consistent and that is really huge for us. That is only down to every member of the team putting in the extra hours and I want to say a big thank you for that,” added Lewis.
