Question: When did the team formerly known as the Renault team design the Lotus E20?

<P0-S0> The Lotus T128, known prior to its launch by its project number TL11, is a Formula One motor racing car designed by Mike Gascoyne for Team Lotus for use in the 2011 Formula One season. <P0-S1>  2011 saw the car abandon its Cosworth engine in favour of one developed by Renault. <P0-S2>  The T128 was launched online on 31 January 2011. <P0-S3>  Team Lotus retained an unchanged driver lineup in 2011, with 2010 drivers Heikki Kovalainen and Jarno Trulli racing the T128. <P0-S4>  It was confirmed that the team would start the season without the Kinetic Energy Recovery System, but senior figures suggested they would adopt it if the car proved successful, however the team continued for the rest of the 2011 season without KERS. <P0-S5>  The team changed from the Cosworth CA2010 engine used in 2010 to the Renault RS27 series, as well as exchanging a transmission developed by X-Trac to one built by Red Bull Technologies. <P0-S6>  The design of the T128 also incorporated a "bladed" rollbar similar to the one developed by Mercedes in 2010, but thicker and with sturdier air intakes to conform with FIA regulations. <SEP> <P1-S0> The Renault R31 was a Formula One racing car designed by Lotus Renault GP for the 2011 Formula One season. <P1-S1>  The car's distinctive black and gold livery was designed as a tribute to the Team Lotus cars of the 1980s and the famous John Player Special liveries (those cars also used Renault engines). <P1-S2>  Speculation suggested that as the design is reminiscent of a cigarette package, the team would be in violation of strict anti-tobacco laws in Canada and would be unable to use it at the 2011 Canadian Grand Prix. <P1-S3>  However, senior team personnel dismissed the claims, stating that "another famous team" was racing with colours similar to those of another tobacco brand and had done so in Canada without trouble in previous years. <P1-S4>  Ultimately, the car raced in Canada with no changes to its livery. <SEP> <P2-S0>  The team competed under the Lotus name from 2012 until 2015, following the renaming of the former Renault team based at Enstone in Oxfordshire. <P2-S1>  The Lotus F1 Team was majority owned by Genii Capital. <P2-S2> Lotus F1 Team was a British Formula One racing team. <P2-S3>  Lotus F1 was named after its branding partner Group Lotus. <P2-S4>  The team achieved a race victory and fourth position in the Formula One Constructors' World Championship in their first season under the Lotus title. <P2-S5>  The team was sold back to Renault on 18 December 2015, The Lotus F1 Team name was officially dropped on 3 February 2016, and announced that they would compete as Renault Sport Formula One Team. <SEP> <P3-S0>  The E20 was the twentieth Formula One car to be designed at Enstone since 1992, and was named in tribute to the contribution made by the facility and its personnel in their twenty-year history. <P3-S1>  The car was also the first from Enstone to carry the Lotus name, since the team ceased using the Renault name following their renaming from Lotus Renault GP at the end of 2011. <P3-S2> The Lotus E20 is a Formula One racing car designed and produced by the Enstone-based Lotus F1 Team for the 2012 Formula One season. <P3-S3>  The team continued to use Renault engines for the car. <P3-S4>  The car, which was launched by the team on its website on 5 February 2012, was driven by 2007 World Drivers' Champion Kimi Räikkönen and 2011 GP2 Series champion Romain Grosjean, both of whom returned to Formula One after a two-year absence.
