McLaren will unveil their 2018 Renault-powered MCL33 on February 23 with Toro Rosso’s STR13 breaking covers two days later.
This season McLaren will race with Renault power after saying goodbye to Honda.
The swap meant McLaren were forced to make a few changes to the car, however, technical director Tim Goss says they managed to do so “without any significant compromise to the chassis.”
McLaren will launch the new car on February 23.
