The last update should be coming for Monza, the car has had all it can from Lotus, the final update is a full and final update of suspension components from Penske.
Then the T127 will just be about optomisation till the end of the season, get that extra 0.5% out of it from setup and general understanding of the package. All in all this should bring Lotus to within a second a lap of STR and BMW Sauber lap time wise.
The car for 2011 is in full swing, and with the anticipated Renault deal being announced soon, the team will not have to worry about engines and gearbox troubles for 2011 as they are taking the whole Renault hydrolic package as well, the only thing they will have to develop is rear suspension on the Renault package.
