The Lotus T128,[1] known prior to its launch by its project number TL11, is a Formula One motor racing car designed by Mike Gascoyne, Lewis Butler and Marianne Hinson for Team Lotus in the 2011 Formula One season. 2011 saw the car abandon its Cosworth engine in favour of one developed by Renault. The T128 was launched online on 31 January 2011.[2] Team Lotus retained an unchanged driver lineup in 2011, with 2010 drivers Heikki Kovalainen and Jarno Trulli racing the T128.
