The last two teams competing in this year’s Formula One World Championship have revealed their race cars for the upcoming season. The first race on the calendar will be the Australian Grand Prix, which takes place in Melbourne on March 25, and will be followed by the Bahrain Grand Prix in early April.

First up, we have Scuderia Toro Rosso and its new STR13, which now features a RA618H Honda power unit instead of a Renault-sourced one that was used in last year’s STR12. The car also sports the team’s familiar blue-and-red livery that now sports ‘Honda Hybrid’ letterings near the sidepods.

For the 2018 season, the STR13 will be campaigned by two drivers that first made their F1 debuts in 2017 – 22-year old French national Pierre Gasly and 28-year old New Zealander Brendon Hartley.

“I am really looking forward to begin this new season and enter a new era for our team, working together with Honda. It’s an exciting time for Toro Rosso because we have not had our own engine supplier before, so to partner with a manufacturer, with the history Honda has, will be great,” said Toro Rosso team principal Franz Tost.

The other team to lift the veils off of its 2018 competitor is Sahara Force India with the VJM11. Last season, the team finished fourth in the constructors’ championship, and is looking to reinforce its proud reputation for punching above their weight.

Powered by a Mercedes power unit, the VJM11 features tighter sidepods and a striking pink livery, the latter without the ‘Force India’ branding as the team is considering a potential name change. Sergio Perez (Mexico) and Esteban Ocon (France) return for another season with the team, after securing the seventh and eighth spots in the drivers’ championship in 2017.

As with every other F1 race car revealed for the 2018 season, both the STR13 and VJM11 gain the Halo protection device, while saying goodbye to T-wings, shark fins and trick suspension – small link in the front suspension connected to the upright allowing ride height to vary over the course of a lap depending on steering angle.
