The Lotus E23 Hybrid is a Formula One racing car which Lotus used to compete in the 2015 Formula One season. It was driven by Romain Grosjean and Pastor Maldonado. This was the team's only car to use Mercedes engines, after a 20-year partnership with Renault.

Images of the 2015 car were released on 26 January 2015.[2][3]

Season summary

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.
