London - Red Bull will give a first glimpse of its new Honda-powered RB15 Formula One car next week on the same day that world champion Lewis Hamilton's 2019 Mercedes breaks cover at Silverstone.
Former champion Red Bull, which finished third overall behind Mercedes and Ferrari last year, has switched from Renault power units to Honda for the season, starting in Australia on March 17.
The team also has a changed line-up, with Australian Daniel Ricciardo now donning yellow Renault overalls and replaced by young Frenchman Pierre Gasly alongside Dutch driver Max Verstappen.
Verstappen, 21, won two races last year and will be hoping Honda provide a reliable and powerful engine after the manufacturer's return to Formula One with McLaren ended in divorce at the end of 2017.
Honda supplied Red Bull's junior team Toro Rosso last year.
