Lotus E23 Hybrid

After the team's dramatic slump in 2014, the 2015 season marked a small improvement in form. The car was considered an improvement compared to the disastrous Lotus E22, which suffered from reliability issues and struggling for competitiveness due to the underpowered and unreliable Renault power unit and the fundamental flaws of the E22 chassis. However, both driver errors and unreliability cost the team points finishes in many races, limiting the car's potential of consistent points scoring. Maldonado retired in 5 out of the first 6 races either due to collisions or car problems. Grosjean and Maldonado collided with each other, in Spain and Britain. A highlight of the season however was Grosjean's podium finish in Belgium. Lotus ended its last season with 78 points and a 6th place in the World Constructors' Championship, before its buyout from Renault Sport. == Sponsorship and livery ==

The livery was completely changed with a new gold graphics design and the red accents were mostly removed while retaining the triple stars (signifying Team Enstone's three Constructors' Championships) behind the cockpit. The team had lost the Rexona sponsorship as Unilever switched into Williams. This was the final year for the following sponsors: Yotaphone, Saxo Bank, PDVSA and Proton. The team promoted the movie Mad Max: Fury Road at the Spanish Grand Prix. The team sponsored Pharrell Williams' recording label I Am Other in Monaco. The team paid tribute to Jules Bianchi in Hungary, with "#JB17" present on the engine cover . At Singapore, Lotus celebrated the launch of the Forza Motorsport 6 and to celebrate, drivers wore green Xbox overalls. ==Complete Formula One results==
