Both Toyota and Porsche have unveiled their Hybrid vehicles set to compete in the FIA World Endurance Championship.

Toyota Gazoo Racing unveiled the latest evolution of its TS050 Hybrid, which the Japanese manufacturer hopes will return them to the top of the FIA World Endurance Championship for the first time since 2014.

A joint effort between engineers in Germany and Japan, Toyota’s new LMP1 challenger has undergone extensive development over the winter to comply with the ACO’s new technical regulations.

The car boasts a new 2.4-liter V6 turbo-charged petrol engine, combined with a smaller, lighter, 8MJ hybrid system delivering 1000 horsepower. A raised nose and sharp undercuts to the sidepods are among the raft of modifications to the bodywork aimed at improving aerodynamic efficiency.

Porsche also revealed its updated 919 Hybrid, which the German team hopes will defend its FIA World Endurance Championship Drivers’ and Manufacturers’ titles in LMP1.

The new 919 Hybrid car features a radically revised aerodynamic package, in compliance with new regulations from the FIA placing limitations on downforce, and will be powered by a 2-liter V4 combustion engine, the most efficient in Porsche’s history to date.

This will be combined with an 8MJ hybrid system which recovers energy during acceleration and braking, generating 900 BHP.

The challengers were revealed to the world media at Monza, where the official two-day Prologue will be staged over the weekend.
