Mercedes will not repeat the development approach it used last year in the upcoming pre-season tests 📖ahead of the 2020 Formula 1 season.

In 2019, Mercedes began testing with a basic car design and initially appeared off the pace, before it introduced a completely revised package 𓃲for its W10 in time for the second test. This car went on𝔍 to race at the Australian Grand Prix and was victorious at the opening eight rounds.

But following the launch of Mercedes’ new W11 challenge▨r at Silverstone, technical director James Allison revealed the German manufacturer will not adopt the same philosophy during this year’s six-days of running at Barcelona.

"We will still have upgrades for Melbourne that will come in the second week of testing, but the 'entire new car' approach of 2019 won't feature," A🦄llison said.

"Last year, the regulations were changed quite significan🌸tly, and they were decided quite late in the year.

“Under those circumsta🐽nces, doing a launch car and a week two car gave us the chance to build the maximum amount of learning into our 🐽Melbourne car.

“With the regulations being more mature this year and with the opening stab of the 202♎0 development already being at the same level as the finish of last year's car, repeating last year's approach would not make sense.”

Allison explained the keyꦡ changes behind the design concept of its W11, which is centred around three key aspects, ꦗincluding an “adventurous suspension layout”.

"The regulations stayed largely the same for the new year, so for us it was all about try🍷ing to make sure that we don't run out of development steam on a package that worked pretty well for us last year," Allison explained.

"We wanted to change aspects of the concept of the car - aspects that would be completely imposꦜsible to change within a s👍eason - to give us a more fertile platform for the new season.

“We tried to make a few well-chosen architectural changes to keep the development slope strong even though the regulations are now a little 🧔bit lo𓃲nger in the tooth.

“At the front we have accepted more structural complexity around the uprights and wheel rims in order to 💜provide a higher perform🀅ance assembly overall,” he added.

"In the m𝓰iddle of the car we have followed the pitlane trend by moving our upper side impact tube to the lower position and banking the aerodynamic gain that comes with this layout.

“At the rea🌠r of the car 🍒we have gone for an adventurous suspension layout in order to free up aerodynamic development opportunity.

“All three 𒀰investments were improvements in t✤heir own right, but their real effect is to mobilise a raft of secondary aerodynamic gains both during the winter and, we hope, across the season to come."
