New Honda F1 engine for Verstappen, will start Italian GP at rear

Honda introduced its Spec 4 engine during the Belgian Grand Prix last weekend, but it was only used by Verstappen's new team-mate Alex Albon and Toro Rosso's Daniil Kvyat.

Albon reverted to a pre-French Grand Prix engine for Saturday and Sunday as Honda was keen on having a fresh unit for the Monza weekend.

On Wednesday, Honda confirmed that both Verstappen and Kvyat's team-mate Pierre Gasly will get a fresh power unit in Italy, meaning both will start from the back of the grid.

"The main development is that we plan to run the Spec 4 PU with all four drivers for the first time after just Albon and Kvyat ran it in Belgium," explained Honda's technical director Toyoharu Tanabe.

"For their first race with Spec 4, Gasly and Verstappen will, therefore, take grid penalties and start from the back of the grid, but we believe they can still race strongly on Sunday.

"We gathered useful data in Spa, which we have used to make changes to PU settings and calibration in preparation for this race.

"We will try to maximise the potential of Spec 4 and hope to get another positive result, maintaining the momentum we gained in Spa."

Verstappen said after the Belgian GP - where he retired after a first-lap accident - that starting from the back at Monza was not a big concern given the overtaking opportunities.

"I think it can be alright to overtake," he told Autosport. "We all know Ferrari is going to be really quick there, and if you start from the back you probably won't catch the top four.

"Everything behind that I think it's possible to catch up with."
